Over-expression of CLDN4 diminishes EphA2 oncogenic signaling even in the absence of E-cadherin. (A) Western blot analysis confirming increased expression of CLDN4 in HEY/mc-CLDN4 cells. (B) qRT-PCR analysis of the effect of CLDN4 over-expression on EphA2 mRNA levels. (C) Representative Western blot showing the effect of over-expression of CLDN4 in HEY cells on total EphA2 protein levels and EphA2 phosphorylation. (D) The histogram shows the mean level of the protein determined from 3 independent experiments. The relative total EphA2 levels in the HEY/mc-CLDN4 cells was expressed as the fold change relative to that in the HEY/mc cells after normalization to ?-actin. The extent of EphA2 phosphorylation in the HEY/mc-CLDN4 cells was expressed as the ratio relative to that in the control HEY/mc cells after normalization to respective total EphA2 levels. Results presented are mean ± SEM (n = 3). *p?<?0.05 versus HEY/mc.
