Figure 1: Effects of LCA on cell viability of T24 cells. Cell viability was determined by using an MTT staining assay. Treatment of T24 cells with varying LCA concentrations (0, 20, 40, 60, 80, or 100 μM) for 12, 24, or 48 h resulted in a significant concentration-dependent and time-dependent reduction in cell viability. The data represent the means   SD of the three independent experiments. , compared with the LCA-untreated control group cell.
