Levels of Rabs and WAVE family proteins associated with translocation of GLUT4 to the cell surface in endometria from hyperinsulinemic PCOS women

Polycystic ovary syndrome (PCOS) is an endocrine-metabolic disorder highly associated with insulin resistance and compensatory hyperinsulinemia. It is known that the insulin signaling pathway is impaired in endometria from PCOS hyperinsulinemic women, but no information is available about molecules associated with cell surface GLUT4 translocation. We therefore evaluated the protein levels of AS160 target molecules, Rab8A and Rab10, and the WAVE family proteins involved in the cortical-actin remodeling, Neural Wiskott-Aldrich Syndrome Protein (N-WASP) and WASP, in endometria from hyperinsulinemic PCOS women and controls.
