We hypothesize that this BBN-induced RGS6 loss represents a critical hit in UBC as it irrevocably impairs the anti-proliferative actions of the ATM/p53 and RASSF1A pathways.
Taken together, our findings established a role for ATDC as a robust pathogenic driver of bladder cancer development, identified downstream effector pathways, and implicated ATDC as a candidate biomarker and therapeutic target.
In contrast, a bladder cancer cell line cotreated with ATM and replication inhibitors progressed more slowly through S phase and showed a marked increase in apoptosis.
Pretreatment with genistein sensitized BDEC and bladder cancer cell lines to HCPT-induced DNA damage by the synergistic activation of ataxia telangiectasia mutated (ATM) kinase.
We examined the associations between bladder cancer and 7 polymorphisms from 5 genes involved in the maintenance of genetic stability (MMR: MLH1-93G>A; BER: XRCC1--77T>C and Arg399Gln; NER:XPC Lys939Gln and PAT +/-; DSBR:ATMG5557A and XRCC7 G6721T) in 302 incident bladder cancer cases and 311 hospital controls.
Depletion of ATM from two cancer cell lines, including the p53-mutant UM-UC-3 bladder cancer line, rendered the cells largely unresponsive to MT-hTer-47A.
