Abstract
Background: Liver regeneration is a critical measure of liver health and plays an essential role in inhibiting the progression of fibrotic lesions and preventing liver failure after hepatocellular carcinoma surgery. However, there are no approved drugs to address this clinical challenge. Methods: The effects of TUDCA on liver regeneration and fibrosis were studied using BRL-3A cells, a partial hepatectomy (PH) rat liver regeneration model, and a carbon tetrachloride (CCl(4))-induced liver fibrosis model. GATA3-knockdown BRL-3A cells were employed to assess the role of GATA3 in TUDCA-induced proliferation. Results: TUDCA promoted the proliferation of BRL-3A cells and enhanced liver regeneration in PH rats while ameliorating liver fibrosis in CCl(4)-treated rats. Additionally, the knockdown of GATA3 eliminated the proliferative effect of TUDCA on BRL-3A cells. Conclusions: TUDCA promotes liver regeneration and alleviates liver fibrosis by activating GATA3.
