PTPN2 knock-down enhances IFNγ-stimulated STAT1+3 phosphorylation. T84 cells were transfected with either non-specific or PTPN2 siRNA and treated with IFNγ (24h). (a) Representative Western blots for PTPN2 and lamin A/C followed by densitometric analysis (n=3). (b,c) Representative Western blots and densitometry showing STAT1+3 phosphorylation and expression (n=3). Figures (a) to (c) represent analyses of whole cell lysates. Asterisks indicate significant differences vs. the respective control (*=p<0.05, **=p<0.01, ***=p<0.001). ###=p<0.001 vs. 24 h IFNγ treatment of control siRNA-transfected cells. (d) Representative Western blots showing PTPN2 and lamin A/C, STAT1+3 expression and phosphorylation, in cytoplasmic and nuclear lysates (n=2).
