(A) Histograms showing cell viability measured by MTT assay in H9c2 cell treated with DTX after 24 h. (B) MTT cell viability assay in H9c2 cells treated with DTX and/or OMT after 24 hours. (C) Annexin V flow cytometry assay on H9c2 cell treated with DTX and/or OMT. (D) Representative density-plots images of Annexin V-FITC/propidium iodide (PI) double staining flow cytometry. (E) Caspase-3 levels in H9c2 cells treated with DTX and/or OMT after 24 hours. (F) Representative western blot autoradiographic images. Data are expressed as mean ± SEM of three or four independent experiments.
