The insulin receptor substrate-2/phosphoinositide 3-kinase (PI3K) pathway plays a critical role in the regulation of β-cell mass and function, demonstrated both in vitro and in vivo. The serine threonine kinase Akt is one of the promising downstream molecules of this pathway that has been identified as a potential target to regulate function and induce proliferation and survival of β cells. Here we summarize some of the molecular mechanisms, downstream signalling pathways and critical components involved in the regulation of β-cell mass and function by Akt.
