Figure 2

Ephrin-A1 activation decreases claudin-2 expression in NSCLC cells. Relative expression of claudin-2 mRNA normalized to endogenous control. Plate A: Cells were either activated with ephrin-A1 or transfected with pcDNA-EFNA1 (vector containing Ephrin-A1 construct) or empty vector. Plate B: Cells either silenced with EphA2 siRNA or transfected with pcDNA-EphA2 (pcDNA-EphA2 is vector containing EphA2 construct) Plate C: Claudin-2 protein expression by Western blot analysis, β-actin was probed to demonstrate equal sample loading. Plate D: Western blot analysis of EphA2 protein expression the β-actin was probed to demonstrate equal sample loading. Data presented was the mean ± SEM of three independent experiments, *p < 0.001 compared to control; #p < 0.001 compared to empty vector; $p < 0.001 compared to sc-siRNA. Plate E: Claudin-2 expression in NSCLC as observed by immunofluorescence analysis. The photomicrographs show immunofluorescence staining of claudin-2 in NSCLC. Blue colour represents the nuclear stain DAPI (4,6-diamino-2-phenylindole), Red colour represents Rhodamin phalloidin for F-actin filament stain, and green colour represents Alexa Flour 488 labelled for claudin-2 expression. The data presented is a single representative of three similar observations Scale Bar = 40 μm.
