BIRC2 and urinary bladder carcinoma: Thus, we have demonstrated that 17-AAG-dependent inhibition of NF-κB activity is tightly associated with transcriptional repression of Survivin and cIAP1 anti-apoptotic genes, thus decisively contributing to the cytotoxic potency of 17-AAG by decreasing the required "apoptotic threshold" in bladder cancer cells [38].
