CP and urinary bladder cancer: To examine the effects of QU and CP on T24 and UMUC human bladder cancer cells under physiological and hyperthermic conditions, exponentially growing cells were treated with 1 or 50 μM QU (QU1 or QU2) and incubated for 2 h, washed and treated with or without 1 or 50 μM CP (CP1 or CP2) for 1 h under physiological (37 °C) and hyperthermic conditions (43 °C), respectively.
