LEP and type 2 diabetes mellitus: We observed numerous terms connected with oxidative stress, DNA repair, cell cycle checkpoints, and ATM (Ataxia Telangiectasia Mutated)-dependent response to DNA damage along with the signaling of cytokines, adipocytokines (8/15 miRNAs), leptin (9/16 miRNAs), interleukin (IL)-1/4/6/7, as well as ADG (10/15 miRNAs) and T2DM (8/16 miRNAs).
