Abstract: ABSTRACT:Objective To validate that relaxin can resist hepatic fibrosis at the cellular level and explore its molecular mechanism in order to provide experimental basis for the treatment of liver cirrhosis.Methods Cultured HSC-T6s were treated with different concentrations (20,50 and 100 ng/mL)of recombinant human relaxin-2 (RLX-2).The proliferation of HSC-T6 was measured by MTT colorimetric assay.The content of type Ⅰcollagen in the cell culture supernatant of each group was detected by ELISA at 48 h of drug intervention;RT-PCR was used to detect the mRNA expressions of CTGF and TGF-β1 in HSC-T6 at 48 h of drug intervention.Results RLX-2 inhibited the proliferation of HSC and reduced type Ⅰ collagen content of HSC cells.It also inhibited the CTGF mRNA expression of HSC,but did not have a significant effect on the expression of TGF-β1 mRNA. Conclusion In the experiment of culturing HSC-T6 in vitro,RLX-2 may play a role in rat liver fibrosis by inhibiting cell proliferation and type Ⅰ collagen and CTGF mRNA expressions.
