Structure Patients treated with tesamorelin for 52 weeks (T-T group) showed no change between Weeks 26 and 52 in mean trunk fat (increase of 0.1 kg in Study 1 and decrease of 0.5 kg in Study 2, respectively, compared with an increase of 1.4 kg in patients in the T-P group in Study 1 and an increase of 1.09 kg in Study 2, respectively) nor was there a change from Week 26 baseline in mean lean body mass (decrease of 0.1 kg in Study 1 and increase of 0.1 kg in Study 2, respectively, compared with a decrease of 1.8 kg in patients in the T-P group in Study 1 and a decrease of 1.7 kg in Study 2, respectively)
Cysteine is a rate-limiting precursor substrate for GSH synthesis, and its level is regulated by SLC7A11 encoding the cystine/glutamate transporter XCT, which is primarily responsible for the export of glutamine in exchange for extracellular cystine [9]
Preclinical research in mice has shown reductions in heart muscle mass and overall heart size after exposure to semaglutide
