Leptin receptor mediated, leptin-induced EMT in breast cancer cells. (AC) Real-time PCR was performed to examine Vimentin, E-cadherin, and CXCR4 expression in MCF-7 and SK-BR-3 cells. Data are shown as the means ± SD. *P<0.05, **P<0.01, ***P<0.001. (D) Western blot was employed to detect Vimentin, E-cadherin, and CXCR4 expression in MCF-7 cells. (EG) Real-time PCR was used to detect Vimentin, E-cadherin, and CXCR4 expression in MCF-7 and SK-BR-3 cells. Data are shown as means ± SD. ns, not significant.
