Polyphenols 98-109 DNA methyltransferase 3 alpha Homo sapiens 58-64 21510884-3 2011 RESULTS: We studied the inhibition of DNA methyltransferase 3a by a series of dietary polyphenols from black tea such as theaflavins and thearubigins and chlorogenic acid derivatives from coffee. Polyphenols 86-97 DNA methyltransferase 3 alpha Homo sapiens 38-62
