RhoA/ROCK and F-actin modeling involved in Insulin secretion

This is the conclusion of Liu X. et al. who demonstrated, in a mouse model, that RhoA/ROCK signaling pathway modulates insulin secretion of 3D cultured islet pancreatic ß-cells. This modulation is made through the regulation of Connexin 36.

Cell-permeable C3 transferase (C3T; Cytoskeleton Inc.) and the small molecule Y-27632 ROCK inhibitor (Stemgent-Asterand) were used in these studies.
