New paper with some thoughts on … Nutrition for Older Adults: Perspectives on Dietary Guidance for Healt… sciencedirect.com/science/articl…

Science is redefining what it means to age. From extending healthspan to tackling chronic disease risk, the latest research is pushing boundaries. @TPR’s The Source breaks down the research with Blake Rasmussen, PhD: bit.ly/45wMc7X

We welcome Dr. Shingo Kajimura to San Antonio this week as our Center for Molecular Metabolism seminar speaker.

We welcome Dr. Jared Rutter to San Antonio as our Center for Molecular Metabolism Seminar Speaker this week! @RutterLab

Yi Zhu, PhD, has received a $150,000 @UTSystem Rising STARs Award to advance aging research & collaborative innovation. The award supports acquisition of behavioral testing and tracking to rigorously assess cognition in aging & Alzheimer’s disease models: bit.ly/4oyTdvI

👏 UT Health San Antonio’s Claude D. #PepperCenter has secured a $6.5M #NIH grant to advance #agingresearch. The funding adds a new Molecular Phenotyping Core + expands efforts to help older adults maintain independence, especially in South Texas. 🧬⏳ 👉bit.ly/46kSHdj

The inaugural cohort of the NIH-funded UT-MSTAR Research Program has completed its training in aging research @UTHealthBarshop. 18 first-year students from 4 Texas medical schools conducted mentored projects, clinical shadowing, and final presentations: bit.ly/3JWUHRL

We are looking forward to hearing from Dr. Teresa Zimmers @tzimmers today in San Antonio.

📢 Join us Sept 10 for the Barshop Institute Fall Seminar Series! 🧬 Teresa A. Zimmers, PhD (OHSU) presents: “Whac-a-mole or Occam’s Razor – Understanding muscle loss in cancer cachexia” 🕓 4–5pm CT | In person & Zoom 👉 bit.ly/4jjeaJw

Sean Kilroe, a productive postdoctoral fellow in the lab, is the first author on a new paper from the lab where we used deuterated water to assess protein synthesis during a week of disuse and exercise rehabilitation. journals.physiology.org/doi/abs/10.115…

We are excited to announce that Dr. JP Palavicini has joined the Department of Cellular & Integrative Physiology as an Assistant Professor, Tenure-Track, Long School of Medicine at UT San Antonio. His area of research is aging and neurodegeneration. lsom.uthscsa.edu/physiology/tea…

Happy to share a new paper led by Pauline Brochet and in collaboration with some of our MoTrPAC colleagues. Endurance Training Enhances Sex-Specific Cardioprotective Metabolism | Circulation Research ahajournals.org/doi/10.1161/CI…

@AbigailMackey1 @MVFranchi @PhysRep We do the same🙂

@TheRasmussenLab @MVFranchi @PhysRep We do sequential biopsies too but if taken too close together there are effects on gene expression and sometimes even cell level. We limit the number of biopsies per VL to 4, separate the sites by 2-3cm and keep the needle perpendicular to the femur.

A very cool one out in @PhysRep by @TheRasmussenLab ! -Transcriptomic time course of skeletal muscle disuse and rehabilitation in middle-aged adults- physoc.onlinelibrary.wiley.com/doi/10.14814/p…

@AbigailMackey1 @MVFranchi @PhysRep Finally, be on the lookout for the first human MoTrPAC study which will be published soon. Hundreds of participants, sequential biopsies before and after exercise, and complete multi-omics analysis of muscle. No sign of sequential biopsies having a confounding influence.

@MVFranchi @PhysRep @TheRasmussenLab 7 Bergstrom biopsies per VL🙈 At least the repeated biopsy effect can be accounted for since the sampling was bilateral but hard to say how much this confounds the data.

@AbigailMackey1 @MVFranchi @PhysRep From one of our studies from 2008 we also show that sequential biopsies have no influence on muscle protein synthesis or amino acid kinetics. pubmed.ncbi.nlm.nih.gov/18713956/

@AbigailMackey1 @MVFranchi @PhysRep Yes there is always the possibility of sequential biopsies having a confounding influence on gene expression. However, our repeated biopsies are obtained on fresh muscle (i.e., not taken from exact location of prior biopsy).
