Research Education Core (REC)

Overview

This Core, led by Paula Shireman, MD, MBA, and Peter Hornsby, PhD, promotes the career development of early-stage investigators. Accessing the research education, training and career development resources of UTHSCSA’s Institute for Integration of Medicine and Science (IIMS) and the robust and unique aging research resources and research education programs in South Texas, our Mentored Research Career Development (San Antonio OAIC RL5) Scholars are trained in the mechanisms that govern the aging process, and in the design of pre-clinical and clinical interventions for diseases and conditions that affect older adults. All San Antonio OAIC RL5 Scholars will have research projects, mentoring teams, and specific short- and long-term career goals. The REC also will sponsor various training and mentoring research experiences. UT Health and its partners offer a rich pool of available trainees and mentors, additional sources of career funding, laboratories, and multiple opportunities for didactic coursework. San Antonio OAIC RL5 scholars also are eligible for pilot support from the PESC.

Features of Training Experience

Program Entry: Scholars will be assessed to determine the competencies needed to move them forward to the next phase of their translational research career focused on aging. Each Scholar will work with a primary mentor and a multidisciplinary mentoring team, essential because Scholars must work with scientists making fundamental discoveries and with clinicians who provide for the needs of older adults with multiple co-morbidities. Milestones for each scholar will be developed that comprise the steps in his or her research project.

Program Progress: During the program, the multi-disciplinary Mentoring Team will monitor Scholar progress at quarterly group meetings. Progress will be measured and documented through written semi-annual self-evaluations with input from the primary mentor and committee.

Program Transition: Across the program there will be a focus on honing grant-seeking skills (e.g., individual career development awards), with activities including the KL2 Seminar Series – ‘Focus on Research Grant Excellence’ (FORGE) and Grant Writing with New Investigators (GWNI). As Scholars complete the program, each will be assisted with the next step of their career.

Core Activities: In addition to the IIMS/San Antonio OAIC RL5 Program curriculum, translational aging research focused training includes: ‘Introduction to Translational Science’ — provides a broad perspective on translational science processes from basic science discovery to population implementation and policy research; a clinical practicum with a San Antonio OAIC faculty member to learn principles of Geriatrics Assessment and measurement (especially important for individuals without prior geriatrics training); ‘Pharmacotherapy of Special Populations’ section related to older adults will provide instruction on drug utilization, impact, and evaluation.

Mitzi Gonzales, PhD

Mitzi Gonzales, PhD
Research Project: Pilot investigation of the role of cellular senescence on gait dysfunction in Alzheimer’s disease

Mitzi Gonzales is an Assistant Professor of Neurology and the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Disorders, who specializes in clinical neuropsychology. Her research broadly focuses on identifying mechanisms and biomarkers of advanced age-related cognitive decline and dementia in effort to aid timely diagnosis, prevent progression, and advance treatment discovery. Dr. Gonzales earned her PhD in Clinical Psychology from The University of Texas at Austin. She completed her pre-doctoral internship at the University of Illinois at Chicago and postdoctoral fellowship in Clinical Neuropsychology at the VA Northern California Health Care System. Dr. Gonzales joined UT Health as a clinical faculty member in 2017. Since her arrival, she has been the recipient of two pilot awards including a translational neuroscience project supported by the Center of Biomedical Neuroscience. Leveraging upon this pilot award, Dr. Gonzales’ RL5 project evaluates senolytic treatment as a novel intervention for reducing gait dysfunction in Alzheimer’s disease. Pre-clinical studies have demonstrated the combination of dasatinib and quercetin cleared senescent cells and decreased tau accumulation, diminished white matter hyperintensities, and rescued aberrant cerebral blood flow. As inflammation, tau accumulation, and altered cerebral blood flow have been linked to gait abnormalities, senolytic treatment may have efficacy for restoring gait dysfunction and improving functional status in Alzheimer’s disease. As an RL5 scholar, Dr. Gonzales will participate in a mentored translational research program across the fields of clinical neuroscience, biology of aging, and clinical trial design to advance her long-term career objective of developing interventions to modulate the pathophysiology of Alzheimer’s disease and attenuate the rate of age-related cognitive decline.

 

Jia Nie, PhD

Jia Nie, PhD
Research Project: Effect of Aging and mTOR Inhibition on Islet Cell Molecular Profiling in Marmosets

Jia Nie, PhD is a postdoc fellow at UT Health San Antonio in the Barshop Institute for Longevity and Aging Studies. She earned her PhD in Biochemistry and Molecular Biology through a joint dissertation between Pennsylvania State University Hershey Medical Center and Nanjing Medical University. Her studies focus on islet biology and metabolic diseases. Her predoctoral research demonstrates a serine/threonine protein kinase that is most closely related to the AMPK kinase mediates insulin secretion and incretin response in islet β-cells. In 2016, Dr. Nie earned a postdoctoral position on the NIA T32 Biology of Aging Training Grant at the Barshop Institute. Aging is the universal contributor to the etiologies of metabolic decline and related diseases, including type 2 diabetes. Clinical cases had reported the remission of human type 2 diabetes is possible but is dependent upon the capacity of islet function. During the T32 training period, her project aimed at identifying how pancreatic islet dysfunction contributes to the metabolic disease progression in older populations and developing therapies to prevent metabolic diseases of aging. By performing single-cell transcriptomic atlas of healthy mouse islets, she found that each cell types within islet at each life stage have different markers and functional characteristics and that age can shift the composition of islet cells contributing to aging progression. In her RL5 project, she will use the common marmoset (Callithrix jacchus) to determine changes in islets molecular profiles during aging, evaluate the contribution of these molecular changes to metabolic disease, and test the effects of lifespan-extending interventions on pancreatic islets. This RL5 opportunity will allow her to develop a unique niche, which can directly translate findings from basic studies to primates, with hope to improve the prevention and treatment of metabolic disease in older adults.

 

Rozmin B. Jiwani, PhD, RN

Rozmin B. Jiwani, PhD, RN
Research Project: Effect of Behavioral Intervention on Frailty in Older Adults with Type 2 Diabetes

Rozmin B. Jiwani, PhD, RN, is an Assistant Professor at the UT Health at San Antonio School of Nursing and has just completed her second year of post-doctoral fellowship at the Geriatrics Research, Education, and Clinical Center (GRECC) at the South Texas Veterans Health Care System. During the fellow-ship she received mentoring from Dr. Espinoza on her NIH R01 funded clinical trial to examine metformin as a potential prevention of physical frailty in older adults with pre-diabetes. Working with Dr. Espinoza, she has been exposed to several other clinical studies and has also gained experience in human subject safety principles and the regulatory process. During the fellowship, her research interests evolved on testing a behavioral lifestyle intervention for overweight/obese older adults with T2D using mobile health tools to enhance self-monitoring of diet and physical activity to prevent or delay the onset of frailty and to manage T2D.

In 2013, she completed her PhD in the field of cardiovascular disease for the high-risk South Asian population, where she explored and measured illness perceptions, coping behaviors, and appraisal in 102 South Asians with coronary artery disease using a mixed methods approach. She modified and translated her dissertation questionnaires into Urdu and Hindi (the prominent languages of South Asians). Her dissertation findings brought to the forefront issues related to traditional diet, sedentary lifestyle, and stress as the modifiable risk factors for their coronary artery disease. In 2015, she completed a yearlong post-doctoral fellowship from the National Institute of Health Funded Health Disparities Steps Toward Academic Research (STAR) Program at the University of North Texas Health Science Center, Center of Excellence on Health Disparities. Completion of this fellowship has fostered her research career to community leaders, and stakeholders committed to addressing health disparities. She has extensive clinical experience as an advanced practice nurse and registered nurse in the field of chronic disease in the adult population. Her program of research is focused on health promotion and disease prevention in the field of cardiovascular diseases and diabetes in vulnerable populations.

Her RL5 project aims to determine the feasibility of a behavioral lifestyle intervention using smartphones for the self-monitoring of diet and physical activity for the improvement of frailty measurements (primary outcome) and on weight management and glycemic control (secondary outcomes) in the overweight/obese community-dwelling older adults with T2D. As a junior investigator in a transdisciplinary research project, working with experienced mentors and gaining mentored career development will provide her with exceptional training experiences that she would otherwise not receive. Dr. Jiwani will continue her pursuit of attaining her long-term career goal for becoming an independent researcher in the clinical and translational field of developing and disseminating interventions to prevent and manage frailty and diabetes complications in community-dwelling older adults.

2015-2017 San Antonio OAIC Scholars

 

Corinna Ross, PhD
Corinna Ross, PhD

Corinna Ross, PhD
Research Project: The effects of chronic rapamycin treatment on motor and cognitive functionin a nonhuman primate model of aging, common marmosets.

Dr. Ross is a basic scientist with a career trajectory that is leading to an emphasis on translational research, with a clear connection to clinical research in aging. Her career development plan reflects this position. Her project continues her ongoing work and moves more centrally to the theme of emphasis of the San Antonio OAIC.

The work builds on the observations made earlier in mice, that a pure pharmaceutical, rapamycin, can reproducibly extend lifespan. This seminal observation set in motion a vast array of investigations in many labs. In particular, it became evident that it would be essential to study rapamycin in nonhuman primates. Whatever the fundamental mechanisms of action of rapamycin, it will be necessary to show that these mechanisms work in primates. In primates investigational studies can be done that are impossible in humans. Therefore there is a clear path from basic observations on standard lab model organisms via nonhuman primates to human subjects.

 

Sukeshi Patel, MD
Sukeshi Patel, MD

Sukeshi Patel, MD
Research Project: A study to evaluate proteostasis modulation with histone deacetylase (HDAC) inhibitors as potential aging modulating agents in cancer patients.

In this project, Dr. Patel is studying the action of a histone deacetylase (HDAC) inhibitor on indicators of the rate of aging in patients with metastatic colorectal cancer.

Dr. Patel represents an important developing area at UTHSCSA, geriatric oncology. While cancer strikes the older population disproportionately, most basic and clinical studies in cancer research are of younger individuals. It is vital to understand the changing biology of cancer in older individuals and to appreciate how these changes impact the effectiveness of therapeutic strategies. Moreover, an emerging concept is that drugs used to treat cancer may act as “gerontogens” – named by analogy with carcinogens, to indicate compounds that can actually cause aging, or change the basic rate of aging.

Dr. Patel’s selection as a OAIC KL2 scholar recognizes that clinician-scientists will be needed to advance the field of geriatric oncology by bridging the gap between basic biology (of both aging and cancer) and the clinical approach to the treatment of cancer in the older individual. Understanding the full potential of the action of chemotherapeutic drugs will need this breadth of understanding.

 

Kelley Reveles, PharmD, PhD
Kelly Reveles, PharmD, PhD

Kelly Reveles, PharmD, PhD
Research Project: Comparison of gut microbiota composition and inflammation in elderly proton pump inhibitor-users and non-users.

Dr. Reveles’ selection as a San Antonio OAIC Scholar reflects the focus of the Center on pharmacological interventions as modulators of human biology that may impact the rate of aging. The unique aspect of this focus is the potential modulation of aging via the gut microbiota. The importance of the microbiota in all aspects of human biology is now being fully realized. Interactions between gut bacteria and diet constituents (including pharmaceuticals) influence many aspects of the immune, endocrine and other physiological systems. Simultaneously these physiological systems can regulate the microbiota. The extensive interactions between the microbiota and the human body are beginning to be realized, but the full extent remains to be discovered. It is quite within the bounds of possibility that we will find that the microbiota actually affect fundamental aging processes – indeed, in C. elegans there is already evidence that this occurs.

The second focus of Dr. Reveles’ research is the class of drugs known as proton pump inhibitors, PPIs, available over the counter and consumed in huge amounts by Americans. The increasing use of these drugs is fueled by the prevailing assumption that long term use of these drugs is safe. However, the lack of stomach acid secondarily affects the colonization of the small intestine by bacteria and subsequently affects the much larger number of bacteria in the colon. The long-term consequences are unknown. Changes to a less favorable mix of species resulting from the change in stomach acid could conceivably have multiple long term adverse effects that involve fundamental aging processes, as Dr. Reveles describes in her project.
