MCL1 and cytomegalovirus infection: Expression level of few other anti-apoptotic genes such as ciap1, cflip and mcl-1 decreased in case of both, WT and ΔDUB-HCMV infection compared with mock infection (Supplementary Figures S1a–S1c), which suggests HCMV-DUB has no specific role in regulating these anti-apoptotic genes.
