INS and Insulin resistance: There is evidence that EGCG restrains insulin resistance and promotes glucose uptake by enhancing GLUT4 transport in skeletal muscle cells, thereby attenuating the β‐cell release of insulin in mouse and human islet cells, and mending the insulin sensitivity of HepG2 cells by potentially lessening ROS‐induced JNK/IRS1/AKT/GSK signalling.113, 114, 115
