ABSTRACT
<p><b>OBJECTIVE</b>To ascertain whether proanthocyanidins inhibit cell growth and migration by increasing let-7a expression in pancreatic cancer AsPC-1 cells.</p><p><b>METHODS</b>The proliferation rate, cell apoptosis rate and cell migration ability of AsPC-1 cells treated with proanthocyanidins were measured by MTT assay, Annexin V-FITC/PI staining, and Transwell migration assay, respectively. The expression of let-7a AsPC cells was detected by miRNA real-time RT-PCR after proanthocyanidins treatment. The changes in the biological behaviors of AsPC-1 cells were evaluated after transfection with let-7a mimics.</p><p><b>RESULTS</b>Compared with the control group, proanthocyanidins treatment caused dose-dependent decrements of the proliferation rate and migration ability and increased the apoptosis rate in AsPC-1 cells. AsPC-1 cells with proanthocyanidins treatment showed increased expression of let-7a. Transfection with let-7a mimics resulted in obvious decreases in the cell growth rate and migration ability, and proanthocyanidins treatment significantly enhanced the inhibitory effect of let-7a mimics.</p><p><b>CONCLUSION</b>Proanthocyanidins-induced cell growth and migration inhibition are partially mediated by up-regulation of let-7a expression in AsPC-1 cells.</p>
