PI3K siRNA and JAK2 siRNA downregulate the production and activation of xanthine oxidase (XO). (A) Representative western blots of p38 MAPK, PI3K, JAK2 and tubulin expression in cardiac microvascular endothelial cells (CMECs). (B) Representative western blot of XO and tubulin expression in CMECs following hypoxia/reoxygenation (H/R). PI3K siRNA-, p38 MAPK siRNA-, JAK2 siRNA- and negative control siRNA-transfected groups compared with H/R group. (C) Summary data (n=3 biological replicates) for western blot analysis of XO and tubulin expression in CMECs following H/R. PI3K siRNA-, p38 MAPK siRNA-, JAK2 siRNA- or negative control siRNA-transfected groups compared with H/R group. ^**p<0.01 vs. H/R group. (D) Representative flow cytometric analysis of DCFH-DA-stained CMECs after H/R. PI3K siRNA-, p38 MAPK siRNA-, JAK2 siRNA- or negative control siRNA-transfected groups compared with H/R group. (E) Summary data (n=3 biological replicates) for flow cytometric analysis of DCFH-DA-stained CMECs after H/R. PI3K siRNA-, p38 MAPK siRNA-, JAK2 siRNA- or negative control siRNA-transfected groups compared with H/R group. ^**p<0.01 vs. H/R group.
