A RaCAS boom: Annual research showcase breaks two-decade record

Students welcome at RaCAS
Joe Pham and Diana Lee, work-study employees of the Experiential Learning Center, greet RaCAS participants in raucous fashion.

Celebrating research from the sciences to the humanities, the 21st annual Research and Creative Activities Symposium (RaCAS) primed creative minds and broke records this year, as more than 500 participants and viewers from the University of Colorado Denver and Anschutz Medical Campus joined in the event.

A record 238 student presentations infused two floors of the Student Commons Building at CU Denver with passionate inquiry on April 27, delving into topics from cancer treatments to virtual learning tools. Under the guidance of a new director, it was the largest RaCAS turnout ever in the research showcase’s two decades.

“That was one of my goals when I took this job,” said Lindsey Hamilton, director of Undergraduate Research and Creative Activities, who accepted the reins as RaCAS director on Jan. 1. “I wanted to bring more awareness to the research that’s taking place on our campuses and change the impression of RaCAS to be more inclusive of all scholarly work.”

Rather than focusing solely on outstanding completed research, Hamilton and crew advertised heavily that projects in progress and of all levels were welcome. “This is a great opportunity to practice presentation,” Hamilton said. “We told them communicating their work was a learning experience and a critical component to their education. And it worked. We had a great turnout.”

For the first time, RaCAS involved student- rather than faculty-organized mini-symposiums, with a record 15 participants. Hamilton also added an Emerging Scholar award to the honoree list, acknowledging the work of 19 students.

Targeting bladder cancer

“This is actually my fourth poster presentation this month,” said Kathleen Nguyen, a bioengineering undergraduate in the College of Engineering and Applied Science, who won a People’s Choice award for her presentation.

“I’ve met so many people. I think this experience is invaluable,” Nguyen said, adding that, in addition to culling connections, presenting at RaCAS and other symposiums helps inspire and prepare students for graduate school.

Looking at how nanoparticles can translate into medical uses, Nguyen highlighted a collaborative research effort in the Nanosafety and Nanotoxicology Lab in the Skaggs School of Pharmacy and Pharmaceutical Sciences. By combining gold nanorods and upconversion nanoparticles, the researchers are working on a noninvasive means of detecting and eradicating bladder cancer.

“We told them communicating their work was a learning experience and a critical component to their education. And it worked. We had a great turnout.” – Lindsey Hamilton, RaCAS director

Gold nanorods contain a property called surface plasmon resonance, Nguyen said. “Basically, that means they oscillate really fast under high-frequency lasers. So, when you shine lasers at near infrared light at these gold nanorods, they vibrate really fast and create a lot of heat, which can be utilized for thermal ablation of bladder cancer.”

By attaching upconversion nanoparticles, which will brightly fluoresce under low-frequency laser light, the aim is to detect and specifically target tumors with the complexes. “The idea is to attach these two together and insert them into the bladder in some sort of solution,” Nguyen said, explaining that the gold nanorod complexes have an anti-EGFR antibody called C225.

“It turns out that bladder cancer tumors have over expression of EGFR, so these gold nanorod complexes will only attach to the tumor,” she said. After the complex solution is allowed to sit in the patient for a short period of time, doctors would insert a catheter with a laser, detecting the tumors with low-frequency light and ablating them with high-frequency light.

Nguyen’s work is focused on how the gold nanorods could be used to activate immune responses that would detect and attack the tumor. “It’s really cool,” she said. “It’s very exciting.”

Bolstering embryology education

Focusing on educating future students in an area she has become passionate about but that has shown signs of declining interest, Angelique Dueñas, a master’s student in Modern Human Anatomy, presented a project weighing the value of 3-D virtual embryos in learning.

“I found it fascinating to see how we develop and why things are the way they are in our bodies,” Dueñas said, explaining her passion for embryology. After seeing a number of literature reviews on the medical curricula’s decreasing emphasis on embryology, she joined colleagues in their efforts to boost interest.

“It’s super important that medical students understand embryology,” Dueñas said. But the field has unique learning challenges. “It’s a three-dimensional subject,” she said of a fetus. “Then you add in time of a developing embryo, and it can be really challenging, especially when the classic presentation is 2-dimensional,” she said of textbook visuals.

So, her team designed 3-D printed models and virtual models and assessed their value. “You can use your mouse and look at all sides of the different organs,” Dueñas said, illustrating with a brightly colored eight-week embryo model on a computer screen. “You can click, and it will tell you what structure you are looking at,” she said, adding that the application used does have virtual-reality capabilities.

After recruiting 162 first-year medical, dental and graduate students, the researchers gave each volunteer a pre-quiz. They then assigned groups to a static pamphlet representation, a 3-D printed version and a 3-D virtual version. Then volunteers completed a post-quiz and survey.

“Students who interacted with the virtual model and the 3-D printed model seemed to increase their pre-test performance statistically significantly,” she said. “The pamphlet group did not.” Nearly 90 percent of students surveyed said they would like to see these resources in other stages and that it would enhance their understanding, Dueñas said. “They said they would even buy these resources, so it was really exciting for us.”

CU Anschutz wins $46.5 million NIH grant

The National Institutes of Health (NIH) recently awarded $46.5 million to the University of Colorado Anschutz Medical Campus and its Colorado Clinical and Translational Sciences Institute (CCTSI), a research partnership designed to speed up development of new treatments to address the greatest health needs of Coloradans.

In 2008, the CCTSI was launched with a grant of $76 million—the largest biomedical research and training award in the state’s history. This new five-year award brings the total funding from NIH to the CCTSI to more than $187 million.

Dr. Shikha Sundaram“The general public may not know the CCTSI name,” says Ronald Sokol, MD, CCTSI director and professor of pediatrics in the School of Medicine. “But they have probably benefited from the research that has come out of our institute over the past 10 years.” Examples include:

  • A cure for hepatitis C, which was made possible in part by dozens of clinical trials that were conducted by CCTSI investigators in our facilities over the past 15 years.
  • Precision medicine treatments for cystic fibrosis that target the defective protein caused by specific gene mutations and which have transformed the lives of patients.
  • Boosting the rates of health screenings that save lives in underserved Colorado communities, such as urban Latino, urban African American and rural eastern Colorado.
  • Decreased mortality rates in five Denver neighborhoods by developing community-based, culturally responsive approaches to tailor educational programs for cardiopulmonary resuscitation (CPR).

“The CCTSI is an engine that has enhanced the research enterprise on the Anschutz Medical Campus for many years,” says Dean John J. Reilly, Jr., MD, of the University of Colorado School of Medicine. “We are proud of their work and confident they will continue to provide essential support and leadership for the next generation of physicians and researchers.”

Over the next five years, the CCTSI will:

  • Develop, educate and sustain a diverse translational science workforce to ensure the highest research innovation, quality and safety.
  • Create a translational research environment in which team science and collaboration both locally and nationally are facilitated, supported and valued.
  • Engage local and national communities and stakeholders in all phases of the translational research process.
  • Create novel methodologies and resources to support and integrate research in special populations, including children, the elderly, the underserved and those with rare diseases.

“The grant will further establish the University of Colorado Anschutz Medical Campus, and all of our institutional partners, as biomedical research leaders, pioneers and innovators,” says Sokol. “We are thrilled to have the opportunity to continue to engage in the full spectrum of translational science to achieve our ultimate goal of getting more treatments to more patients more quickly.”

Study shows prenatal cannabis use associated with low birth weights

With marijuana use during pregnancy on the rise, a new study led by the Colorado School of Public Health shows that prenatal cannabis use was associated with a 50 percent increased likelihood of low birth weight, setting the stage for serious future health problems including infection and time spent in Neonatal Intensive Care Units.

New study shows association between prenatal cannabis use and low birth weights.

“Our findings underscore the importance of screening for cannabis use during prenatal care and the need for provider counselling about the adverse health consequences of continued use during pregnancy,” said the study’s lead author Tessa Crume, PhD, MSPH, assistant professor of epidemiology at the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus.

The study was published last month in The Journal of Pediatrics.

Crume and her colleagues utilized survey data from 3,207 women who participated in the Colorado Pregnancy Risk Assessment Monitoring System in 2014 and 15. They found the prevalence of marijuana use in the state of Colorado was 5.7 percent during pregnancy and 5 percent among women who were breastfeeding.

They also discovered that prenatal marijuana use was associated with a 50 percent increased chance of low birth weight regardless of tobacco use during pregnancy. Prenatal marijuana use was three to four times higher among women who were younger, less educated, received Medicaid or WIC, were white, unmarried and lived in poverty.

Crume said the numbers are surprising but also reflect changing attitudes toward marijuana, especially in a state like Colorado where it is legal.

“There is increased availability, increased potency and a vocal pro-cannabis advocacy movement that may be creating a perception that marijuana is safe to use during pregnancy,” Crume said.

The National Survey on Drug Use and Health suggests that cannabis use among pregnant women has increased as much as 62 percent between 2002 and 2014. At the same time, the potency of the drug has increased six or seven fold since the 1970s along with the ways it is consumed – eating, vaping, lotions etc.

“Growing evidence suggests prenatal cannabis exposure has a detrimental impact on offspring brain function starting in the toddler years, specifically issues related to attention deficit disorder,” Crume said. “But much of the research on the effects of prenatal cannabis on neonatal outcomes was based on marijuana exposures in the 1980s and 1990s which may not reflect the potency of today’s cannabis or the many ways it is used.”

The study found that 88.6 percent of women who used cannabis during pregnancy also breastfed. The risk of cannabis to the infant through breastmilk remains unknown. Various studies have found that cannabinoids are passed to the baby in this way. One of the study’s co-authors, Dr. Erica Wymore, MD, MPH, from Children’s Hospital Colorado and the CU School of Medicine, is currently conducting a study to evaluate this issue.

The researchers recommend that health care providers ask pregnant women about their cannabis use and advise them to stop during pregnancy and lactation.

“Obstetric providers should refrain from prescribing or recommending cannabis for medical purposes during preconception, pregnancy and lactation,” Crume said. “Guidance and messaging about this should be incorporated into prenatal care. And screening of pregnant women at risk for cannabis dependency should be linked to treatment options.”

The study co-authors include Ashley L. Juhl MSPH, of the Colorado Dept. of Public Health and Environment; Ashley Brooks-Russell, PhD, MPH, of the Colorado School of Public Health; Katelyn E. Hall, MPH, of the Colorado Dept. of Public Health and Environment; Erica Wymore, MD, MPH of the University of Colorado School of Medicine and Children’s Hospital Colorado and Laura M. Borgelt, PharmD, of the CU Skaggs School of Pharmacy and Pharmaceutical Sciences.

Annual Department of Medicine Research Day 2018

Battling breast cancer, hepatitis C and the nationwide opioid-addiction crisis were just three of the research goals highlighted as part of the Department of Medicine’s sixth annual Research Day on the University of Colorado Anschutz Medical Campus.

Gathered in the Fulginiti Pavilion on April 6, the department within the CU School of Medicine recognized 22 students, faculty and staff for their outstanding research achievements as part of the event. Focused on showcasing the diverse accomplishments at CU Anschutz, the event encourages discussion and collaboration across the the Department of Medicine’s multiple disciplines.

This year, a diverse panel of faculty judges selected 22 outstanding abstracts – all submitted by Department of Medicine students, postdocs, fellows and junior faculty. The researchers were then invited to present their projects at Research Day, said Jennifer Kemp, director of the Department of Medicine Research Office.

“The Research Day poster session presents a unique opportunity for our researchers to present their latest work to a broader audience than is typically found at a more specialized conference,” Kemp said. “This broad audience brings the potential to spark new ideas and catalyze new collaborators in different fields.”

Cancer biology

Lynsey Crump shares her research in cancer biology.

Lyndsey Crump, a third-year student in the Cancer Biology

program in the Graduate School, works in Traci Lyons’s lab. Crump has been exploring how signaling proteins can affect breast cancer progression. Specifically, she has looked at SEMA7A (Semaphorin 7A) and how its presence may indicate a worse prognosis.

“I want to try to help people,” Crump said of her passion in cancer biology. “One day I want to see this lab work to translate to clinical work, to give patients another potential course of treatment.”

Hepatitis C and public health

Andy Bryant, MD, studies hepatitis C in special populations.

Andy Bryant, MD, is an internal medicine resident at CU Anschutz studying the treatment of hepatitis C in a “safety net” population, or those who are either uninsured or have Medicare or Medicaid.

“Until this study, this population was overlooked,” said Bryant as he walked onlookers through his research. “Unfortunately, these people usually come in a lot sicker than those with traditional insurance. This means that their prognosis isn’t very good.”

Recent studies have helped underscore the potential for a new drug (DAA) that can cure hepatitis C. Originally, Medicaid and Medicare did not cover this drug, but Bryant’s findings help show the long-term potential savings of administering DAA.

Opioid prescribing habits

Angela Keniston, MSPH, an instructor in the department of hospital medicine, studies the prescribing habits of health care providers across the world.

Angela Keniston researches cultural opioid prescribing habits.

“Specifically, we wondered, do doctors in the United States prescribe opioids more?” Keniston said. “The answer, one we’ve all suspected, was yes.”

 

In conjunction with her study, Keniston also looked into cross-cultural patients’ perceptions of pain across cultures.

In the long run, Keniston would like to help doctors understand their patients’ expectations of pain, and ultimately change prescribing habits. “Pain is a normal experience,” she said. “We need our providers to shape the conversation with patients to help curb this prescribing epidemic in our country.”

Vascular problems associated with symptoms of menopause and quality of life measures

A new study shows that more frequent and severe menopausal symptoms such as hot flashes, sleep disturbance, loss of sexual interest, weight gain and other quality of life measures, were associated with markers of vascular aging, according to researchers at the University of Colorado Anschutz Medical Campus.

The researchers, however, found no association between these vascular markers and symptoms of depression. The study was published online today in Menopause, the Journal of the North American Menopause Society.

Kerry Hildreth, MD
Dr. Kerry Hildreth, MD, assistant professor in the Division of Geriatric Medicine, CU School of Medicine.

“The menopausal transition is a vulnerable time for women in terms of vascular health,” said the study’s lead author Kerry Hildreth, MD, assistant professor in the Division of Geriatric Medicine at the University of Colorado School of Medicine. “Many women also experience menopausal symptoms that can negatively affect their quality of life and can contribute to depression, which is an established risk factor for cardiovascular disease. We investigated whether these symptom and mood aspects of menopause were associated with markers of vascular aging.”

Hildreth and her colleagues studied 138 healthy women grouped according to the stage of menopause. They found that arteries were stiffer, and the endothelium, the layer of cells that line the blood vessels, was progressively less healthy across the stages of menopause. Menopausal symptoms and depression symptoms were greatest, and quality of life was lowest, in the late-perimenopausal and early postmenopausal stages. Importantly, more severe menopausal symptoms and lower quality of life were associated with worse vascular function.

Unique study

“To our knowledge this was the first study to examine the association of mood, menopausal symptoms, and quality of life measures with these key markers of vascular aging in a well-characterized population of women spanning the stages of menopausal transition,” the study said.

Dr. Kerrie Moreau, PhD, associate professor

Women entering menopause experience profound hormonal changes coinciding with adverse changes in cardiovascular disease risk factors like high blood pressure, weight gain and insulin resistance, the study said. This may help explain the acceleration of vascular aging during the menopause transition.

Although the majority of women do not experience depression during the menopause transition, the risk is two to three times higher than in premenopausal women. One hypothesis is that the brain has to adapt to the irregular fluctuations in estrogen, a potent neurosteroid, during perimenopause, and eventually to a new, lower baseline level after menopause. This may explain why depressive symptoms returned to lower levels in the late postmenopausal women.

But while the researchers did not find an association between depression and vascular dysfunction across the stages of menopause, they did find an association with common menopausal symptoms. These include vasomotor symptoms, such as hot flashes, palpitations and headaches, and general symptoms, such as sleeplessness, poor appetite, constipation, weight gain, and poor concentration.

Estrogen loss could play role

The reasons behind these changes are unclear but loss of estrogen could play a key role.

“Estrogen modulates the synthesis and uptake of serotonin which has neuromodulatory, thermoregulatory, and cardiovascular actions,” the study said. “Fluctuating and declining levels of estrogen with the menopausal transition may alter serotonin activity.”

Another culprit could be oxidative stress. Estrogen is a potent anti-oxidant and higher levels of oxidative stress are seen in estrogen-deficient, post-menopausal women compared to premenopausal women, according to the study. Hot flashes are also associated with higher oxidative stress.

Hildreth said the next step is studying the mechanisms underlying these associations between vascular aging and symptoms of menopause.

“A better understanding of these aspects of the menopausal transition will be important for developing effective lifestyle and therapeutic interventions to promote psychosocial well-being and cardiovascular health in women,” Hildreth said.

The other authors of the study include Kerrie Moreau, Ph.D.*, University of Colorado School of Medicine; Cemal Ozemek, Ph.D., University of Illinois at Chicago; Wendy Kohrt, Ph.D.*, University of Colorado School of Medicine, Associate Director of the Center for Women’s Health Research; Patrick Blatchford, Ph.D.*, Colorado School of Public Health.

Discovery could speed clinical translation of stem cell therapies

A team of scientists from the University of Colorado School of Medicine and the Charles C. Gates Center for Regenerative Medicine at CU Anschutz has reported a more efficient approach to reprogramming a patient’s diseased skin cells into stem cells, raising hopes for future clinical trials and potential cures for critical illnesses.

The results were published on Feb. 21, 2018 in Nature Communications.

The team is reporting a clinically safe approach that consistently reprograms healthy and disease-associated patient’s skin cells into induced pluripotent stem cells (iPSCs) with an unprecedented efficiency.

Dr. Dennis Roop, director of the Charles C. Gates Center for Regenerative Medicine.
Dennis Roop, PhD, director of the Charles C. Gates Center for Regenerative Medicine.

Since its initial discovery in 2006 by Shinya Yamanaka, MD, PhD, iPSC reprogramming technology has created considerable interest in the field of regenerative medicine for its potential of providing an unlimited source of patient-specific cells suitable for transplantation. This technology involves the reprograming of adult skin cells taken from a donor into immature embryonic stem cell-like iPSCs. These iPSCs can be grown outside the body, genetically manipulated, converted into a variety of adult cell types and then either transplanted back to the same patient as an autograft or used as a platform for drug screening and research.

Despite significant advances, current methods for reprogramming adult cells into iPSCs are extremely inefficient and inconsistent, with less than 1 out of every 500-1000 adult human cells becoming iPSCs. The low efficiency of these protocols, coupled with the length of time in culture, increase the chances of accumulating harmful mutations in iPSCs, thus compromising the safety of this technology for clinical applications.

To address the issue of low reprogramming efficiency, the team from the University of Colorado Anschutz Medical Campus optimized the cellular delivery of modified mRNAs, encoding several reprogramming factors in combination with microRNAs, and improved cell culturing conditions to enhance the growth of cells undergoing conversion into iPSCs.

“Many groups had previously attempted to improve reprogramming efficiency by identifying novel modulators of the process,” said Ganna Bilousova, PhD, an assistant professor of dermatology and one of the study’s lead scientists. “Instead of looking for new reprogramming enhancers, we took advantage of the versatility of RNA molecules to control the precise levels of reprogramming factors and microRNAs in cells during their conversion into iPSCs. We were surprised at how simple manipulations of the timing and dosing of the RNA molecules could affect the efficiency of reprogramming.”

The researchers showed that the fine-tuning of RNA delivery and cell culturing conditions dramatically enhanced the efficiency of reprogramming and improved the consistency of the process for disease-associated skin cells.

“Initiating reprogramming at a reduced cell density was critical for improving reprogramming efficiency in our study,” said Igor Kogut, PhD, an assistant professor of dermatology at the Gates Center. Kogut is also one of the paper’s lead authors. “There is a direct correlation between the rate of cell division and the efficiency of reprogramming. Our optimal, combinatorial RNA delivery regimen, which reduced the toxicity of the protocol, made it possible to initiate the process at a reduced cell density, down to individually-plated single cells.”

The goal now is to move the technology from the laboratory into clinical trials. Gates Center Director Dennis Roop, PhD, who is also one of the lead authors on the paper, recognizes the magnitude of the team’s work. He believes it holds great potential for the development of new corrective stem cell-based therapies for currently incurable diseases, such as Epidermolysis Bullosa (EB). Roop has had a long-standing interest in finding a permanent cure for EB, a group of inherited skin diseases that results in severe blistering and scarring. EB affects thousands of people across the United States and worldwide, and is characterized by chronic skin wounds similar in property to thermal burns, and indistinguishable from burns induced by chemical agents such as mustard gas.

“There are no effective therapies for EB, and iPSC technology provides an opportunity to develop a permanent corrective stem cell-based therapy for these severe skin-blistering diseases,” said Roop. “Our breakthrough in developing a highly-efficient reprogramming method, that avoids the use of viral vectors, may allow us to get FDA approval for one of the first iPSC-based clinical trials in the U.S..”

To accelerate getting iPSC-based therapies for EB into the clinic, the CU Anschutz team has established a consortium comprised of the University of Colorado, Stanford University (Anthony Oro, MD, PhD) and Columbia University (Angela Christiano, PhD).

The “EB iPS Cell Consortium” was initially supported by the EB Research Partnership (EBRP), the EB Medical Research Foundation, and the SOHANA Research Fund. More recently, the Consortium has received funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases through the 21st Century Cures Act for the Regenerative Medicine Innovation Project, and the California Institute for Regenerative Medicine’s Partnering Opportunity for Translational Research Projects. The research teams at both Stanford and Columbia have adopted the University of Colorado’s reprogramming technology as the method of choice for generating patient-specific iPSCs for future clinical trials, and thus are setting the standards for future iPSC-based therapies for other diseases.

Prior to receiving the above sources of funding for the Consortium, this study was supported by additional funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the US Department of Defense, the Foundation for Ichthyosis & Related Skin Types, the Dystrophic Epidermolysis Bullosa Research Association (DEBRA) International, The King Baudouin Foundation’s Vlinderkindje Fund, the Linda Crnic Institute for Down Syndrome, the Gates Frontiers Fund and private donors.

Curiosity: It’s what makes new interim vice chancellor tick

Robert Eckel at desk
Dr. Robert “Bob” Eckel is serving as interim vice chancellor for research while a search for a permanent replacement is underway. Eckel has served as program director of the Clinical Translational Research Center Network of the Colorado Clinical Translational Sciences Institute (CCTSI) and the CU Adult General Clinical Research Center. He was only the second endocrinologist ever to serve as president of the American Heart Association.

It might have been what killed the cat, but to Dr. Robert “Bob” Eckel, the University of Colorado’s new interim vice chancellor for research, curiosity reigns in propelling a successful career and research program.

“It’s what drives the bus here,” said Eckel, MD, recently tapped for the job left vacant by Dr. Richard “Dick” Traystman’s death this fall, as CU administrators launch a search for a permanent vice chancellor.

Although “filling Dick’s shoes is impossible,” Eckel, an international expert in his field of lipid and lipoprotein metabolism and a recognized face on the CU Anschutz Medical Campus after nearly 40 years, said he hopes his ingrained curiosity can serve as a catalyst for furthering the research enterprise at an institution that has been good to him and his profession.

“There are many components to a successful career in science and medicine,” Eckel said. “But curiosity, in my opinion, is one of the most important factors. If curiosity is driving you, then grants, papers and quality research will follow.”

Fanning the curiosity flame

The curiosity flame was lit early in Eckel’s career. After conceding that he was no Vivaldi and ditching the thought of a profession in music (a passion that led him to his first wife, a talented violinist), Eckel decided his idea of medical school was more on track. “And I knew it would make my mother happier.”

But his vision of being solely a clinically-focused doctor soon vanished. “I found out during my residency in internal medicine that I was starting to get increasingly curious about what made people sick and why they weren’t responding to therapy,” said Eckel, an endocrinologist in both the School of Medicine’s Division of Endocrinology, Metabolism and Diabetes and Division of Cardiology. He also has an appointment in the Department of Physiology and Biophysics.

“I thought if I wanted to pursue that drive, that ultimately I needed to be trained in research,” said Eckel, crediting his subsequent research-fellowship experience at the University of Washington for fanning the flames. “I came out on fire for research.”

‘There are many components to a successful career in science and medicine. But curiosity, in my opinion, is one of the most important factors. If curiosity is driving you, then grants, papers and quality research will follow.’ – Robert Eckel, MD

Bringing a dual perspective

Eckel, who often calls himself a “cross-dresser” as a preventive cardiologist and endocrinologist, said he loves all components of his job. “As a clinician, I’m more of a preventive cardiologist, but as a scientist, I’m a metabolically-driven guy,” he said, adding that his physician-scientist perspective brings a different “twist” to the vice chancellor position.

As an investigator, Eckel thrives on being tucked in his lab, where he and Assistant Research Professor Kimberley Bruce, PhD, have expanded their longtime focus on how lipids (such as cholesterol and triglycerides) and lipoproteins (which carry lipids) relate to obesity, metabolic syndrome, diabetes and cardiovascular disease.

The two have joined forces with Wendy Macklin, PhD, a leading expert on glial biology in the Department of Cell and Developmental Biology, in investigating how lipids and lipoproteins play a role in neurological disorders, such as Multiple Sclerosis and Alzheimer’s disease, with a renewed funding award on Feb. 1.

“Myelin is loaded with lipids,” Eckel said, referring to the myelin sheath that protects the body’s nervous system. With MS, a disabling degenerative disease that affects an estimated 400,000 Americans, myelin is slowly destroyed. “So we are involved in understanding how lipids and lipoproteins can be processed to re-myelinate nerves that have been demyelinated.”

Dr. Robert Eckel poses with Rocky and wife, Margaret, at a Nuggets game. Eckel credits the women in his life for much of his success.

Encouraging research partnerships

Bruce and Eckel have also teamed up with another top CU Anschutz Medical Campus researcher, SOM’s Department of Neurology’s Huntington Potter, PhD, in their work on the role of lipids and lipoproteins and the brain-degenerating Alzheimer’s disease. Alzheimer’s affects at least 5.5 million Americans, a number expected to soar with an aging population.

During her years working beside him, Bruce said Eckel has served as a great mentor and role model. “I’ve learned a great deal from Bob, not just about lipid and lipoprotein biology, but also about how to strive for scientific excellence while still keeping your feet on the ground,” she said. “I honestly can’t think of anyone better for this vice chancellor role.”

No stranger to cross-disciplinary collaboration, Eckel said researcher success also depends on networking. “None of us is an island anymore in science and medicine. There are no single-authored papers anymore. Science is really teamwork, and that’s something I will consider as I look at the big network of research on both campuses.”

Recognizing research’s influence

Eckel, winner of the Endocrine Society’s 2016 Outstanding Clinical Investigator Award, understands the power of research on both a professional and a personal level.

Diagnosed at age 5 with Type 1 diabetes, a disease he shares with two sons and opted early on to separate from his lab work, Eckel said he’s grateful for his colleagues who have made huge research strides in the insulin-related disorder.

“There’s been so much improvement in therapeutics for Type 1 diabetes,” he said. “I have a pump and a sensor,” he said, patting his lower chest, where a pump automatically infuses the insulin his body cannot make. “I’ve had this disease for 65 years now, and I’ve never felt better in my life. I feel fortunate to be alive, and that’s research,” he said.

Finding collaboration on all fronts

Eckel with family
Dr. Robert Eckel balances career and family, which includes three grandchildren and five grown children. Eckel, who emphasizes the importance of music in a well-rounded lifestyle, taught each of his kids piano until they were in sixth grade.

Eckel doesn’t just stand out in his field. In 2016, he won Father of the Year from the American Diabetes Association, for which he serves on the board. A devoted but humble family man, he doesn’t take the credit for his well-rounded success.

“It’s the women I’ve done it all with,” he said, acknowledging his first wife, who worked as a teacher while he went through medical school and then raised their five children before she died of breast cancer at age 45. “She was a great mom.”

Eckel eventually married his current wife, Margaret. “She stepped up and became a stepmom who’s now loved by all of my kids, and I’ve been married to her almost as long as I was my first wife. So I had great companionship and love from two women, and I probably didn’t deserve either one of them.”

On the professional side, Eckel said Bruce “runs the bus” in his research lab. “She’s smarter than I am. I’m lucky to have her.” With a retirement date set for July 1, 2019, Eckel hopes to have his research program ready to hand over to Bruce and to have fulfilled his new interim post to the best of his ability.

“I work at a great institution that’s been incredibly supportive, and it’s a privilege to serve,” said Eckel, who will not vie for the permanent post. “But right now, I’m neither intellectually nor emotionally ready to retire. The science is just too much fun.”

CU Anschutz students present research to lawmakers at Capitol

More than 50 researchers greeted Colorado lawmakers entering the Capitol building on Jan. 19, with the aim of raising awareness of the importance of research. Colorful posters highlighting the young scientists’ projects lined the rotunda’s walls, as the presenters’ lively voices bounced around the room’s large marble structures while they explained their work.

Hannah Hathaway, PhD, is proud to share her research.

“This is such a great event,” said Hannah Hathaway, PhD, president of the University of Colorado Postdoctoral Association, as she stood amid the array of posters targeting a wide range of disciplines, from biomedical to atmospheric research. “Not only do we get to present our work in a unique way, but we also get to see other research going on in Colorado.”

Early-career scientists representing 11 state institutions of higher education, including the CU Anschutz Medical Campus, CU Denver and CU Boulder, attended the event, hosted by the CU Anschutz chapter of Project Bridge. Bruce Mandt, PhD, director of the CU Postdoctoral Office, and Jerry Johnson, the CU contract lobbyist for state relations, helped the group with the event.

Project Bridge

“The goal of Project Bridge is to give scientists more tools to succeed by teaching them to communicate outside the world of academia,” said Erin Golden, PhD, president of the national student organization. “We accomplish this through holding trainings, inviting speakers to campus and engaging in a variety of advocacy events like the Capitol Investment.”

Golden launched the CU Anschutz chapter last year after coming from Johns Hopkins University, where Project Bridge was founded.

Erin Golden, PhD, is excited with the turnout of Capitol Investment Day.

“It’s great to see everything come together,” Mandt said. “It is so important to showcase the broad range of scientific work from around the entire state of Colorado.”

Gov. Hickenlooper declared Jan. 19, 2018, “Early Career Scientist Day” to commemorate the event, aimed at showing lawmakers the importance of funding research. The event boasted 71 of 100 state legislators, who pledged their attendance as co-hosts.

Career Development

While waiting for the legislators to arrive, researchers shared their short presentations with one another. The presentations and posters were designed to be informal and jargon-free.

“This type of presentation is unusual for scientists,” Mandt said. “Our presenters are getting excellent experience in explaining their work to a lay audience. This is a wonderful career-development opportunity.”

“If I have accomplished something today, it would be relaying how impactful this scientific exploration is,” said Christopher Covey, a fifth-year graduate student in CU Anschutz School of Medicine’s Department of Immunology & Microbiology. “We’ve all worked so hard to approach scientific problems from new angles. Maybe one day we will uncover something that was previously overlooked.”

Golden hopes Project Bridge will grow to include more events and that Capitol Investment will become an annual event.

“We’re so excited with the turnout,” said Golden. “We really feel like we are making a difference in Colorado’s scientific community, while giving our peers the tools they need to succeed.”
