Biological/Functional activity & target protein

Anticancer activity

Cell growth inhibition, and modified the expression of cell cycle regulatory proteins p53, p21, cyclin B1, BAD, cytC, c-casp3, Survivin, and BIRC7. The peptide contributed to the antiproliferative effect on human colorectal cancer cells by modifying molecules involved in either cell cycle arrest or apoptosis. Based on the antiproliferative effect, HCT116 cell line was most sensitive to bean Azufrado Higuera (IC₅₀ = 0.53 mg/ml) and RKO to Bayo Madero (IC₅₀ = 0.51 mg/ml) peptide extracts. Both cultivars increased significantly (p < 0.05) the expression of p53 in HCT116 by 76% and 68%, respectively. Azufrado Higuera modified the expression of cell cycle regulation proteins p21 and cyclin B1. Bayo Madero modified the expression of mitochondrial activated apoptotic proteins BAD, cytC, c-casp3, Survivin, BIRC7.
