Fig. 6From: High expression level of serpin peptidase inhibitor clade E member 2 is associated with poor prognosis in lung adenocarcinomaEffect of SERPINE2 knockdown on apoptosis. Western blotting analysis of apoptosis-related proteins at the indicated time points after Fas ligand stimulation is shown. A549 (upper) and PC9 (lower) cells pretreated with SERPINE2 siRNA were stimulated with Fas ligand (200Ā ng/ml). nc, negative control; #2, siRNA#2Back to article page
