ABSTRACT
<p><b>AIM</b>To observe the effect of FAK-related non-Kinase (FRNK) plasmid on hepatic stellate cell (HSC) proliferation stimulated by fibronectin (FN).</p><p><b>METHODS</b>FRNK plasmid was transfected into HSC with transient liposomal transfection. The proteins of FRNK, FAK and p-FAK(Tyr397) were assayed by Western blotting analysis. The proliferation of HSC was evaluated by improved MTT assay, and cell cycle pattern was determined by flow cytometry (FCM).</p><p><b>RESULTS</b>(1) The expression of FRNK protein increased after FRNK transfected HSC, and it was at 48 h that the expression of FRNK protein was the highest (P < 0.01). The protein level of FAK was no significant difference between before FRNK plasmid transfection and after transfection (P > 0.05). The expression of p-FAK(Tyr397) protein was down-regulated after FRNK had been transfected in HSC, (P < 0.01). (2) The HSC proliferation inhibition rates at 12 h, 24 h and 48 h after FRNK transfection were 20.07%, 26.16%, 29.77%, respectively (P < 0.01). (3) Compared with the non-FRNK plasmid group, the FRNK-transfected HSCs almost arrested in G0/G1 phase (71.4 +/- 2.81 vs 48.9 +/- 1.66, P < 0.01).</p><p><b>CONCLUSION</b>After FRNK were transfected successfully in HSCs using lipofectamine, the phosphorylation of FAK was inhibited. The HSC proliferation was restrained in a time-dependent manner and the HSC was arrested in G0/G1 phase.</p>
