Consequently, we confirmed reduced activity of mTOR signaling components and higher expression of atrophy-related markers typified by FoxO1/atrogin-1/MuRF1 and myostatin-Smad2/3 signaling during the course of diabetes.
The present study investigated the effect of diabetes and acute muscle contraction upon the TRIM63 and FBXO32 expression as well as the potential involvement of some miRNAs.
Under various pathophysiological muscle-wasting conditions, such as diabetes and starvation, a family of ubiquitin ligases, including muscle-specific RING-finger protein 1 (MuRF1), are induced to target muscle proteins for degradation via ubiquitination.
