FTO inhibits UPRmt-induced apoptosis by activating JAK2/STAT3 pathway and reducing m6A level in adipocytes

As a nucleic acid demethylase, Fat and obesity associated gene (FTO) plays a vital role in modulating adipose metabolism. However, it is still unknown how FTO affects apoptosis in adipocytes. In this study, we found that overexpression of FTO inhibited the expression of pro-apoptosis factors Caspase-3, Caspase-9 and Bax and mitochondrial unfolded protein response (UPRmt) markers HSP60 and ClpP in vivo and in vitro. Particularly, overexpression...
