ABSTRACT
<p><b>OBJECTIVE</b>To explore the role of estrogen in the regulation of the expression of claudin-6 and biological behavior in MCF-7 cells.</p><p><b>METHODS</b>RT-PCR and immunocytochemistry were conducted to analyze the expression and localization of claudin-6 in MCF-7 cells treated with 17β-estradiol. CCK-8 kit assay and Scratch Test were conducted to analyze the capability of proliferation and migration of 17β-estradiol treated MCF-7 cells.</p><p><b>RESULTS</b>RT-PCR analysis and immunocytochemistry showed that 17β-estradiol induced a concentration-and time-dependent effect on claudin-6. At 5 nmol/L and at 24 h, 17β-estradiol treatment led to an increased level of claudin-6, which was located in the membrane of MCF-7 cells. CCK-8 analysis showed a significant decrease in the capability of proliferation of MCF-7 cells compared with the control group (P < 0.05). Cells Scratch Test showed decreased migration capability of MCF-7 cells compared with the control group (P > 0.05).</p><p><b>CONCLUSIONS</b>17β-E2 might regulate the expression of claudin-6 and inhibit the proliferation and migration of MCF-7 cells. The inhibitory effects of 17β-E2 on growth and migration of MCF-7 cells may be mediated by claudin-6 expression regulation.</p>
