A. 832/13 cells were transduced with adenoviruses encoding either βGAL, wild-type STAT1 (WT), STAT1Y701F, STAT1S727A, STAT1Y701F/S727A (DM; double mutant) or STAT1S727T. STAT1 abundance was determined by immunoblotting. B, C. 832/13 cells were transduced with the adenoviruses indicated in (A); 24 h post-transduction cells were stimulated for 3 h with either IL-1β (1 ng/mL) alone or IL-1β plus IFN-γ (100 U/mL). *p<0.05, #p<0.1. D, E. Rat islets were transduced with the indicated adenoviruses. 24 h post-transduction cells were stimulated with both IL-1β (10 ng/mL) and IFN-γ (100 U/mL) for 3 h. ***p<0.001, **p<0.01. Relative mRNA abundance of Cxcl9 (B, D) and Cxcl11 (C, E) was determined by RT-PCR. Date are expressed as means ± SEM from 3 (B, C) or 2 (D, E) individual experiments. The immunoblot in A was repeated on two individual occasions.
