ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of LY294002 on the adriamycin- induced epithelial-mesenchymal transition in human breast carcinoma cells.</p><p><b>METHODS</b>Human breast carcinoma cells MCF-7 was cultured in vitro and then exposed to adriamycin with or without LY294002. The protein expression levels of Akt, phosphorylated-Akt (p-Akt), Snail, and E-cadherin was detected by Western blot analysis. The mRNA expressions of Snail and E-cadherin were determined by RT-PCR.</p><p><b>RESULTS</b>Adriamycin significantly increased the protein expression of Snail and depressed the protein expression of E-cadherin (P<0.05). The pre-treatment with LY294002 significantly reversed the changes of activities and levels of the above proteins (P<0.05).</p><p><b>CONCLUSION</b>LY294002 could reverse the adriamycin-induced epithelial-mesenchymal transition in human breast carcinoma cells by regulating the expressions of Snail and E-cadherin through suppressing PI3K/Akt signaling pathway.</p>
