Abstract : Chickpea seed proteins are alleged source of nutraceuticals. These seed proteins were subjected to different proteases to produce peptides. The efficacy of these peptides was confirmed using six diverse human cancer cell lines (PA-1, Ishikawa cells, A549, MCF-7, HepG2, MDA-MB-231). Alcalase generated peptides exhibited the highest antagonistic inhibition of Ishikawa cells. Flow cytometric analysis revealed that chickpea peptide induced S and G2 phase arrest of cell cycle in a dose dependent manner. DNA fragmentation and apoptosis occurred by down regulation of Bcl-2 expression, upregulation of Bax expression and promotion of caspase-3 initiation. Chickpea peptides ascertain potential antiproliferative molecule that can be deployed in cancer treatment regimes.
