(B) Representative Western Blot analysis of endogenous KIFC1 and STIM1 proteins (both normalized on total tubulin levels) in ECs silenced with a control siRNA (siCTL) or one targeting KIFC1 (siKIFC1) or two control siRNAs (siCTLsiCTL) or two targeting KIFC1 and STIM1 (siKIFC1siSTIM1). Results are the average ± SD of three independent experiments and analyzed by a parametric two-tailed analysis of variance (ANOVA) with Bonferroni post hoc analysis. ANOVA p≤ 0,01; Bonferroni for siCTL and siKIFC1, KIFC1 expression p≤ 0,001 ***, STIM1 expression p> 0.05 not significant (ns) and for siCTLsiCTL and siKIFC1siSTIM1, KIFC1 expression p≤ 0,01 **, STIM1 expression p≤ 0,05 *.
