Protein expression profile of cell cycle regulating proteins: Representative Western blot analysis of cell cycle regulating proteins in parental (par) and cisplatin-resistant (res) T24 cells after 48 h exposure to 2.5 µM ART (A). Pixel density analysis of protein expression (B–K), compared to untreated controls (set to 100%), is illustrated. Each protein analysis was accompanied and normalized by a total protein control. Error bars indicate standard deviation (SD). Significant difference to untreated control: * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001. n = 3. For detailed information regarding the Western blots see Supplementary Materials Figure S1.
