Apoptosis plays a pivotal role in the exclusion of abnormal cells without any ruin of surrounding healthy cells. Generally, it occurs through an orderly and autonomously process which is controlled by proper function of various genes. Therefore, the current experiments detect the expression level/pattern of those genes to confirm the involvement of extrinsic and intrinsic pathway using Basella alba leaf (BAL). Several fractions after gel filtration chromatography of BAL extract have been pooled to evaluates its apoptosis induction potentiality on Ehrlich's Ascites Carcinoma (EAC) cells through conducting a number of bio-assays such as cell growth inhibition assay, fluorescence and optical microscopy, DNA fragmentation assay and gene expression analysis etc. The pooled fractions of BAL showed 12-56% inhibitory effect on EAC cell line at the concentration range of 25-400 µg/ml that was determined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. They also exhibited excellent cell growth inhibition at in vivo and in vitro condition when treated with 10, 20 and 40 mg/kg day. After administration of six consequent days, significant morphological features of apoptosis were observed in EAC cells under both fluorescence and optical microscope which was further supported by DNA fragmentation assay. The polymerase chain reaction amplification of bax, bcl-2 (B-cell lymphoma 2), p53, tumor necrosis factor-α, Fas, NF-kß (Nuclear factor-Kappa-B), PARP-1 (Poly (ADP-ribose) polymerase), Cyt-c cas-8, cas-9 and cas-3 revealed that the experimental sample able to induce apoptosis in both extrinsic and intrinsic pathways through altering the gene expression. The current findings suggest that sample from BAL occupy wonderful competence to induce cell apoptosis and become an ideal resource for cancer treatment.
