Fig. 9From: Proximal tubule-derived exosomes contribute to mesangial cell injury in diabetic nephropathy via miR-92a-1-5p transferIllustration of the mechanism of PTEC-derived exosomal miR-92a-1-5p in DN. HG increased miR-92a-1-5p expression in PTECs, which in turn induced ER stress and MFT in MCs through exosome delivery targeting RCN3 in DNBack to article page
