Article Title: Combination Therapy with Betulinic Acid and TRAIL Increases ROS-Dependent Cytotoxicity and Inhibits PI3K/Akt Signaling in Human Bladder Cancer Cells
doi: 10.4062/biomolther.2026.035
Figure Lengend Snippet: Combination treatment with BA and TRAIL increases mitochondrial damage and induces changes in the expression levels of Bcl-2 family proteins in T24 human bladder cancer cells. T24 cells were treated with BA and TRAIL alone or in combination and cultured for 24 h. (A, B) After treatment, the cells were stained with 5,5′,6,6′-tetrachloro-1,1′,3,3′-tetramethylbenzimidazolyl carbocyanine iodide (JC-1) and analyzed via flow cytometry. Representative histograms (A) and the frequency of cells with JC-1 monomers (B), indicating mitochondrial membrane potential (MMP) loss, are shown. * p <0.05 vs. control cells; ### p <0.001 vs. BA-treated cells (n=3). (C, D) Mitochondrial and cytosolic fractions were isolated from the cells (C), total protein was extracted (D), and immunoblotting was performed using antibodies against target proteins. Cytochrome c oxidase (COX IV) and β-actin were used as loading controls for the two fractions, respectively.
