Effects of IFN-?1b on morphology and the expression of connective tissue growth factor in hepatic stellate cells / 中国病理生理杂志

ABSTRACT

AIM: To observe the effect of (IFN-?1b) on morphology and the expression of connective tissue growth factor (CTGF) in hepatic stellate cells (HSC). METHODS: HSC were cultured in vitro, and were treated with (IFN-?1b) and TGF-?_1. The changes of HSC on morphology were observed, and the expression of CTGF in HSC was assessed using reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Phenomenon of apoptosis were observed in HSC treated with IFN-?1b. The expression of CTGF in HSC was decreased after treatment with (IFN-?1b) in control and TGF-?1-triggered groups. CONCLUSION: (IFN-?1b) is able to induce the apoptosis and suppress the expression of CTGF in HSC.
