Senescent Leydig Cell Elimination & Testosterone Restoration in Aged Mice (Aging / PMC, 2020) FOXO4-DRI Disrupts FOXO4-p53 in Senescent Leydig Cells and Improves Testicular Microenvironment A study published in Aging (and indexed on PMC) demonstrated that FOXO4 is specifically expressed in human Leydig cells, with nuclear translocation of FOXO4 in elderly men correlating with decreased testosterone synthesis
Glucagon receptor activation drives energy expenditure and thermogenesis, allowing researchers to study both energy intake suppression and active caloric expenditure simultaneously a mechanistic capability not available with GIP/GLP-1 dual agonists or GLP-1 mono agonists
