Cao et al. (2015) revealed that the TSA-induced apoptosis in T24 bladder cancer cells is related to TRPM2 (Transient Receptor Potential Cation Channel, Subfamily M, Member 2) upregulation, which is caused by increased H3K9Ac enrichment within the TRPM2 promoter [229]. Here, TRPM2 is linked to urinary bladder cancer.
