Figure 1: Effects of IL6 on cell proliferation in human bladder carcinoma cells. (a) Culture medium samples were collected for ELISA analysis to determine IL6 protein expression in different bladder carcinoma cell lines. Data are presented as mean (±SE, ) of the IL6 protein levels. (b) HT1376 cells were treated with various concentrations of exogenous recombinant human IL6 as indicated for 72 h. Cell proliferation was determined using the 3H-thymidine incorporation method. Each point on the curve represents the mean percentage ±SE ( ) of 3H-thymidine incorporation in the control group. * .
