ABSTRACT
This study was aimed to observe the effects of Gui Curcuma extract on proliferation, collagen production, and matrix metalloproteinase (MMP) expression by hepatic stellate cells (HSC-LX2). HSC-LX2 were cultured in DMEM broth (10% FBS), then treated with Gui Curcuma extract (with the concentration of 0, 22.5, 45, 90 μmol·L-1) for 24 h. The proliferation of HSC-LX2 was measured by MTT assay; injury in HSC-LX2 was indicated with LDH re-lease; collagen I production was detected by ELISA; and MMP-l expression was determined by Western blot. The re-sults showed that Gui Curcuma extract (with the concentration of 22.5, 45, 90 μmol·L-1) dose-dependently inhibited proliferation of HSC-LX2 by 16.2%, 43.9%, 59.4% in MTT assay, respectively. The IC50 was 59.1 μmol·L-1. There was no significant impact on LDH release. The Gui Curcuma extract (with the concentration of 45, 90 μmol·L-1) can significantly reduce the expression of collagen I level (P< 0.01), whereas MMP-1 expression was significantly uplift-ed (P< 0.05) by Gui Curcuma extract (with the concentration of 45, 90 μmol·L-1) in Western blot. It was concluded that Gui Curcuma extract had the potential to prevent hepatic fibrosis, through inhibiting proliferation and collagen I production, and increasing MMP-1 protein expression.
