ABSTRACT
OBJECTIVE:
To study inhibitory effect of Lycianthes biflora polysaccharide on the proliferation of hepatic stellate HSCs-T6 cells in rats and its mechanism.METHODS:
After treated with 0(blank control),50,100,200μg/ml L. biflora polysac-charide for 24 and 48 h,the activity of hepatic stellate HSCs-T6 cells in rats was determined by MTT assay and inhibitory rate of cell proliferation was calculated;the content of Hyp in supernatant was detected by immunohistochemical assay. After 48 h,the ex-pression of cellular α-smooth muscle actin(α-SMA)was measured by immunohistochemical assay;both transforming growth fac-tor β1(TGF-β1)and Smad3 were measured by Western blot assay.RESULTS:
Compared to blank control,50,100 and 200 μg/ml L. biflora polysaccharide could inhibit the proliferation of HSCs-T6 cells;cell inhibitory rates were 39.84%-69.31% and 45.16%-82.93% respectively after treated for 24 and 48 h,which were positively associated with time and concentration. The con-tents of Hyp in supernatant were 178.36-93.25 μg/ml and 131.94-68.74 μg/ml respectively after treated with different concentrations of PRP for 24 and 48 h,which were negatively associated with time and concentration. The protein level of TGF-β1 and Smad3 de-creased after treated with L. biflora polysaccharide for 48 h(P<0.01).CONCLUSIONS:
L. biflora polysaccharide can inhibit the proliferation of hepatic stellate HSCs-T6 cells in rats,and its mechanism is associated with the inactivation of endogenous TGF-βpathway for reducing collagen production.
