  Federal

  Funding Agency National Institutes of Health Title University of Texas Adult Clinical Center, NIH Molecular Transducers of Physical Activity Consortium (MoTrPAC) Status Active Period 12/2016 - 11/2022 Role Principal Investigator Grant Detail The purpose of the MoTrPAC is to catalyze the identification and mapping of molecular and cellular transducers underlying the physiological effects of physical activity. Funding Agency NIH/NIA Title San Antonio Nathan Shock Center of Excellence in the Biology of Aging Status Active Period 7/2015 - 6/2020 Role Co-Principal Investigator Grant Detail The purpose of the Nathan Shock Center is to support aging research at the Health Science Center by providing core services that are of exceptional interest to researchers in the biology of aging.
  Role: Core Director, Healthspan Core Funding Agency NIH Title San Antonio Claude D. Pepper Older Americans Independence Center Medicine Status Active Period 6/2015 - 4/2020 Role Principal Investigator Grant Detail The central premise underlying the proposed San Antonio Claude D. Pepper Older Americans Independence Center (OAIC) is that we are at a point in the history of aging research when there are scientifically valid anti-aging therapies to test in humans. We propose an Intervention Program that will move forward discoveries obtained in rodents to the pre-clinical arena using a non-human primate model, the common marmoset, and from the pre-clinical arena to humans through randomized clinical studies. Our Center will provide investigators with state-of-the-art scientific infrastructure and services that are required in developing innovative interventions which target the aging process and aging-related diseases. Initially, a major focus will be on pharmacologic interventions, however, regenerative and gene transfer interventions also will be tested as they become available. The Specific Objectives of the OAIC are: 1. To provide support, through Resource Core (RC)-1, to pre-clinical studies in non-human primates to investigate the mechanism of action, efficacy, and tolerability of aging interventions. This Core also will provide functional assessment (healthspan) services and will determine the effect of interventions on lifespan. 2. RC-2 will provide human clinical research and pharmacology services to studies of interventions aimed at preventing physiological decline and aging-related diseases. Services provided by this core include subject recruitment, compliance, and procedures to assess physical performance, cognition, glucose metabolism, vascular function, atherosclerosis, exercise tolerance, gait, balance, imaging, and specimen (blood, muscle, fat) processing. This core also performs pharmacokinetic human studies. 3. To provide, through the Biostatistics Core (RC3), expertise in data entry systems, data quality control, data security, and state of the art quantitative and qualitative analytic and medical informatics strategies. 4. To provide assistance to faculty for Funding Agency NIDDK Title Role of TLR4 on insulin resistance in human subjects Status Active Period 9/2014 - 9/2018 Role Principal Investigator Grant Detail The purpose of this study is to determine the role of toll-like receptor 4 (TLR4) on insulin resistance and type 2 diabetes in human subjects.
