A study by E. S. Scarpa et al. suggested that the combined use of XVX and BC caused an enhanced antitumor activity concerning the increased expression of pro‐apoptotic Bax, and downregulation of anti‐apoptotic BIRC5 (Survivin) and pro‐survival CTNNB1 (β‐Catenin) in T24 bladder cancer cells (Scarpa et al., 2016). The gene discussed is BIRC5; the disease is urinary bladder carcinoma.
