Anti-mutagenic and Pro-apoptotic Effects of Apigenin on Human Chronic Lymphocytic Leukemia Cells
Diet can play a vital role in cancer prevention. Nowadays the scientists are looking for food materials which can potentially prevent the cancer occurrence. The purpose of this research is to examine anti-mutagenic and apoptotic effects of apigenin in human lymphoma cells. In present study human chronic lymphocytic leukemia (Eheb cell line) were cultured in RPMI 1640 (Sigma), supplemented with 10% fetal calf serum, penicillin-streptomycin, L-glutamine and incubated at 37 ºC for 2 days. In addition cancer cell line was treated by and apigenin and cellular vital capacity was determined by MTT assay. Then effect of apigenin in human lymphoma B cells was examined by flow cytometry techniques. The apigenin was subsequently evaluated in terms of anti-mutagenic properties by a standard reverse mutation assay (Ames test). This was performed with histidine auxotroph strain of Salmonella typhimurium (TA100). Thus, it requires histidine from a foreign supply to ensure its growth. The aforementioned strain gives rise to reverted colonies when expose to sodium azide as a carcinogen substance. During MTT assay, human chronic lymphocytic leukemia revealed to have a meaningful cell death when compared with controls (P<0.01) Apoptosis was induced suitably after 48 hours by flow cytometry assay. In Ames test apigenin prevented the reverted mutations and the hindrance percent of apigenin was 98.17%.These results have revealed apigenin induced apoptosis in human lymphoma B cells in vitro.
