MUC1-C and PBRM1/PBAF drive ISG15 and SERPINB9 expression. (a). Expression of ISG15 and SERPINB9 in the TCGA-PRAD cohort was assessed in MUC1-high and MUC1-low groups using a Wilcoxon rank-sum test. (b). Lysates from DU-145/tet-MUC1shRNA treated with vehicle or DOX for 7 days were immunoblotted with antibodies against the indicated proteins. (c). Lysates from DU-145/CsgRNA or DU-145/MUC1sgRNA#1 were immunoblotted with antibodies against the indicated proteins. (d). Lysates from DU-145/CshRNA and DU-145/PBRM1shRNA cells were immunoblotted with antibodies against the indicated proteins. (e and f). DU-145/tet-MUC1shRNA cells treated with vehicle or DOX for 7 days were stimulated with 10 ng/ml IFN-γ for 24 hours. Analysis of the indicated genes in vehicle- and DOX-treated cells showing significant differences in mRNA levels (e). Lysates were immunoblotted with antibodies against the indicated proteins (f). (g). Lysates from DU-145/CshRNA and DU-145/PBRM1shRNA cells stimulated with 10 ng/ml IFN-γ for 24 hours were immunoblotted with antibodies against the indicated proteins.
