Human Obesity Metabolism (HOMe) Lab

A Research Group (Christos Katsanos, PhD, PI) at Arizona State University investigating the biology behind muscle health impairments in humans with obesity.

Our review in Comprehensive Physiology with @DrZhenqiLiu and Philip Atherton discusses evidence that GLP-1 RAs may improve muscle vascular function and glucose metabolism, while outlining the unresolved questions around muscle protein metabolism.

New in PNAS: Age-related muscle decline is driven by mitochondrial dysfunction—but exercise can remodel mitochondria, restore muscle function, and reduce frailty, even later in life.

Back-to-back papers from @AlexKeeble5 and @saragonzalezve . Working with @MVFranchi , we show that limb suspension and post-ACLR muscle exhibit fundamentally different muscle transcriptomic signatures.

Super proud to share the first original research paper from my new lab:

"Weight loss with GLP-1 medicines does not result in a disproportionate loss of muscle mass or function in obese mice and humans"

A very important point is the safety point: this paper shows you can significantly decrease myostatin levels throughout a person’s lifetime, and the result is more muscle, less fat, increased strength, and no noticeable side effects
