The process of insulin resistance is associated with defects in insulin signalling downstream of insulin receptor (INSR) [85], insulin Receptor Substrate 1/2 (IRS-1/2) [86], Phosphoinositide 3-Kinase (PI3K)/AKT Serine/Threonine Kinase (AKT) [87] and Glucose Transporter 4 (GLUT4) [88]. The gene discussed is AKT1; the disease is Insulin resistance.
