For example, resveratrol, which is found in peanuts, soybeans, purple grapes, and pomegranates, inhibits pancreatic cancer cells by regulating N-cadherin [44], and epigallocatechin-3-gallate (EGCG) found in green tea (Camellia sinensis, Theaceae) and genistein first isolated from Genista tinctoria suppressed metastatic activity by downregulating MMP-2 expression in some types of cancers in melanoma, breast cancer and prostate cancer [45,46,47,48]. This evidence concerns the gene MMP2 and prostate cancer.
