TGFB1 and liver dysplastic nodule: The lncRNA-ASncmtRNA-2 (antisense mitochondrial non-coding RNA-2) was upregulated in DN of Lepr−/−(db/db) mice in vivo and high glucose-stimulated mesangial cells in vitro, promoting TGF-β1 and fibronectin expression in a ROS-dependent mechanism, where shRNA-mediated ASncmtRNA-2-silencing and ROS inhibition by NG-nitro-L-Arginine methylester (L-NAME) effectively suppressed DN and high glucose-induced TGF-β1 and fibronectin expression [65].
