Figure Lengend Snippet: A . Left panel, immunoblotting of total proteins from INS-1E cells, 72 h after transfection with a negative siRNA (siNeg) or siRNAs against Cdk5r2 (siCdk5r2#1 and siCdk5r2#2). Right panel, quantification of the corresponding Cdk5r2 protein levels. Results are mean ± SEM of three independent experiments. ** P <0.01 versus values of siNeg-transduced INS-1E cells. B . Quantification of apoptotic nuclei in non-transfected INS-1E cells (NT) and INS-1E cells transfected with a negative siRNA (siNeg) or with siRNAs against Cdk5r2 (siCdk5r2#1 and siCdk5r2#2), treated 24 h with a mix of cytokines (black bars) or not (white bars). Results are mean ± SEM of six independent experiments. ** P <0.01 versus controls. C . Immunoblotting of total proteins from INS-1E cells transfected with a negative siRNA (siNeg) or siRNAs against Cdk5r2 (siCdk5r2#1 and siCdk5r2#2), treated 24 h with a mix of cytokines (Cyt) or not (Ctrl). The cleavage of caspase-9 and −3, induced by cytokines, is higher in siCdk5r2- than in siNeg-treated cells. D . Quantification of apoptotic nuclei in non-transfected INS-1E cells (NT) and INS-1E cells transfected with a negative siRNA (siNeg) or siRNAs against Cdk5r2 (siCdk5r2#1 and siCdk5r2#2), exposed 15 h to control medium (white bars) or palmitate (black bars). Results are mean ± SEM of six independent experiments. ** P <0.01 versus controls.
