TNFSF10 and urinary bladder cancer: To examine if non-toxic concentration of RH enhances the sensitivity of the bladder cancer cells to TRAIL-mediated apoptosis, we treated TRAIL-sensitive bladder cancer cells 5637 with 10 μg/mL of RH and 5 ng/mL TRAIL combination, and TRAIL-resistant bladder cancer cells T24, BIU 87 with 10 μg/mL of RH and 20 ng/mL TRAIL combination.
