“…Amino acid sequences of these peptides were LPHVLTPEAGAT from papain hydrolysate and PTAEGVYMVT, from protease XXIII and both of them exhibited dose-dependent antiproliferative activities against human breast adenocarcinoma (MCF-7) cells, (Hsu et al, 2011;Ryan et al, 2011;Udenigwe and Aluko, 2012). Picot et al (2006) reported 18 protein hydrolysates isolated from blue whiting, cod, plaice, and salmon to have antiproliferative activity against 2 human breast cancer cell lines (MCF-7/6 and MDA-MB-231) (Picot et al, 2006;Shahidi and Zhong, 2008;Ryan et al, 2011). In addition, it has be shown that hydrophobic peptide isolated from anchovy sauce, with molecular weight of 440.9 Da, induced apoptosis in a human lymphoma cell line (U937), (Lee et al, 2003;Lee et al, 2004;Ryan et al, 2011).…”
