Abstract
Objective To investigate the effect of Rapamycin( RAPA)on proliferation and apoptosis of rHSCs -99 in vitro. Methods The rHSCs -99 was divided into four groups - Control group ( A) , RAPA 50 nmol/L group( B), RAPA 100 nmol/L group( C) , RAPA 150 nmol/L group ( D). After 72 h of Rapamycin interference in rHSCs - 99, the MTT colorimetric assay was used to detect the proliferation of rHSCs - 99; synthesis and secretion of collagen I were detected by ELISA; Annexin - V FICT/PI double - label immuno fluorescence with flow cytometry was used to examine the apoptosis of rHSCs - 99; Wright - Giemsa staining method was used to observe the morphologic change of rHSCs -99; Immunocytochemical staining was used to observe the proteinum expression of Fas, P53 and Bcl - 2. Results After the rHSCs - 99 were interfered with RAPA, rHSCs - 99 proliferation were inhibited; the content of type I was reduced; the number of Fas, P53 positive was increased and the Bcl - 2 positive was decreased. Conclusion RAPA inhibits the proliferation of the rHSCs - 99 and reduces the content of collagen I of ones, facilitating the cell apoptosis. The mechanism which RAPA promote rHSCs - 99 apoptosis may be through opening the Fas/FasL apoptosis pathway, up -regulating Fas,P53 and inhibiting Bcl -2 expressing to come true.关键词
