| 1 | Specific shRNA targeting of FAK influenced collagen metabolism in rat hepatic stellate cells显示文摘AIM:To investigate the effects and mechanism of disruption of focal adhesion kinase(FAK) expression on collagen metabolism in rat hepatic stellate cells(HSC).METHODS:The plasmids expressing FAK short hairpin RNA(shRNA) were transfected into HSC-T6 cells,and the level of FAK expression was determined by both real-time quantitative polymerase chain reaction(QPCR) and Western blotting analysis.The production of type collagen and type collagen in FAK-disrupted cells was analyzed by real-time Q-PCR.The level of collagen metabolism proteins,including matrix metalloproteinases-13(MMP-13) and tissue inhibitors of metalloproteinases-1(TIMP-1) was also determined by both real-time Q-PCR and Western blotting analysis.RESULTS:The transfection of FAK shRNA plasmids into HSC resulted in disrupted FAK expression.Compared with the HK group,the levels of type collagen and type collagen mRNA transcripts in FAK shRNA plas-mid group were signif icantly decreased(0.69 ± 0.03 vs 1.96 ± 0.15,P = 0.000;0.59 ± 0.07 vs 1.62 ± 0.12,P = 0.020).The production of TIMP-1 in this cell type was also signif icantly reduced at both mRNA and protein levels(0.49 ± 0.02 vs 1.72 ± 0.10,P = 0.005;0.76 ± 0.08 vs 2.31 ± 0.24,P = 0.000).However,the expression of MMP-13 mRNA could be significantly up-regulated by the transfection of FAK shRNA plasmids into HSC(1.74 ± 0.20 vs 1.09 ± 0.09,P = 0.000).CONCLUSION:These data support the hypothesis that shRNA-mediated disruption of FAK expression could attenuate extracellular matrix(ECM) synthesis and promote ECM degradation,making FAK a potential target for novel anti-f ibrosis therapies. | Zhi-Na Dun Xiao-Lan Zhang Jun-Yan An Li-Bo Zheng Robert Barrett Shu-Rui Xie | 2010 | World Journal of Gastroenterology2010，16，32： | 8 |
