The capacity of pancreatic β-cells to adapt to insulin resistance is critical to maintain glucose homeostasis and a factor in the development of Type 2 diabetes. The insulin receptor substrate (IRS-2/phosphoinositide 3-kinase (PI3K) pathway plays a critical role in regulating β-cell mass and function. The serine-threonine kinase Akt also known as protein kinase B is one of the major downstream targets of the PI3K pathway and is negatively regulated by phosphatase and tensin homologue deleted on chromosome 10 (PTEN). This Akt signaling pathway recently has been implicated in cell cycle progression and survival of pancreatic β-cells. Understanding the mechanisms that link Akt to modulation of β-cell mass, function and plasticity will positively affect treatment of human diabetes.
