PLN-1474 (10 μM) decreases the expression level of profibrotic genes, including COL1A1 and TIMP1 in liver[1].
PLN-1474 significantly reduces levels of pSMAD3/SMAD3 in liver, hepatic collagen gene expression and hepatic OHP concentration in a mouse model of liver fibrosis[1].
PLN-1474 (6-12 weeks) prophylactically or therapeutically blocks SMAD3 phosphorylation and significantly decreases OHP levels, collagen gene expression, and collagen deposition examined histologically in the CDAHFD NASH mouse model[1].
