ABSTRACT
<p><b>OBJECTIVES</b>To investigate the effects of FAK-related non-kinase (FRNK) on expressions of type I collagen and matrix metalloproteinase-2 (MMP-2) mRNA and tissue inhibitor of metalloproteinase-2 (TIMP-2) mRNA in rat hepatic stellate cells (HSC).</p><p><b>METHODS</b>Using in vitro cell culture technique, FRNK plasmids were transfected into HSC mediated by cationic liposome. Type I collagen synthesis capability in HSC was examined by 3H-Pro incorporation assay. The levels of FRNK in HSC were assayed by Western blot, and the expressions of MMP-2 and TIMP-2 were assayed by RT-PCR on mRNA levels.</p><p><b>RESULTS</b>The exposure of HSC to FRNK caused the expression of FRNK protein to be up-regulated, and the FRNK protein contents reached the highest point at 48 h after the transfection, P less than 0.05. The expressions of MMP-2 mRNA were up-regulated by FRNK; the expressions of TIMP-2 mRNA were down-regulated by FRNK; the ratios of MMP-2 mRNA/TIMP-2 mRNA were enhanced by FRNK.</p><p><b>CONCLUSION</b>After FRNK was transfected, the capability of type I collagen synthesis in HSC was inhibited, which may be related to the up-regulation of MMP-2 mRNA/TIMP-2 mRNA.</p>
