The antiproliferative activity of 3-deoxyanthocyanins extracted from red sorghum (Sorghum bicolor) bran through P53-dependent and Bcl-2 gene expression in breast cancer cell line

Aims: The aim of this study was to investigate the anti proliferative activity of 3-deoxyanthocyanin extracted from red sorghum bran on human breast cancer cell line MCF 7. The confirmatory tests were carried out in vitro through the expression studies of p(53) and (bcl) 2 genes in MCF 7 cells. Method: The 3-deoxyanthocyanins were isolated from red sorghum bran and cytotoxic studies were performed in MCF 7 cell line by MTT assay. The mRNA expression levels of p(53) and (bcl) 2 genes were performed using semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) analysis in MCF 7 cells. Key findings: On cytotoxic studies, the present data indicates sorghum anthocyanins, which showed 84.09% of inhibition in the proliferation of MCF 7 cells, and the CTC50 value was 300 mu g/ml. The sorghum 3-deoxyanthocyanins induced apoptosis in MCF 7 was mediated by stimulation of the p53 gene and down regulation of the (bcl) 2 gene. Significance: The significance of our work was the anthocyanin isolated from red sorghum bran inhibits the proliferation of human breast cancer cell line. (c) 2013 Elsevier Inc. All rights reserved.
