AKT1 and type 2 diabetes mellitus: They found that exosome-derived extracellular miR-20b-5p is highly abundant in type 2 diabetic patients, and further in vitro studies showed that exosomal miR-20b-5p targeted AKT-interacting protein (AKTIP), which interacts directly with AKT and modulates AKT activity by enhancing the phosphorylation of AKT regulatory sites and reducing glycogen accumulation in primary human skeletal muscle, resulting in insulin resistance [83].
