Effect of tetrandrine on bax, bcl-2 and TGF-β2 mRNA expressions in cultured human Tenon's capsule fibroblasts / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of tetrandrine (Tet) on the expression of bax, bcl-2, and transforming growth factor-β2 (TGF-β2) mRNA in cultured human fibroblasts of Tenon's capsules (TCFS) and explore its possible mechanism.</p><p><b>METHODS</b>The third passage of TCFS cultured in vitro were exposed to 1×10(-5) mol/L Tet for 24 h, and real-time fluorescence quantitative PCR was used to detect the changes in the expressions of bax, bcl-2, and TGF-β2 mRNA.</p><p><b>RESULTS</b>The expression level of bax mRNA was obviously higher, while bcl-2 and TGF-β2 mRNA levels were significantly lower in Tet-treated TCFS than those in the control cells (P<0.05).</p><p><b>CONCLUSION</b>Tet can inhibit the proliferation of TCFS possibly by reducing the expressions of bcl-2 and TGF-β2 mRNA, enhancing the expression of bax mRNA and inducing cell apoptosis, suggesting its potential in preventing fibrous scar formation after glaucoma filtration surgery.</p>
