These plant peptides can inhibit the proliferation, adhesion, and migration, promote apoptosis, induce cell cycle G0/G1 phase arrest of breast cancer cells, as well as lead to overexpression of apoptosis-related proteins such as caspase 3, caspase-7, caspase-8, thereby hindering the progression of breast cancer. This evidence concerns the gene CASP3 and breast carcinoma.
