Theaflavin-2 (TF-2), a major component of black tea extract, induces apoptosis of human colon cancer cells and suppresses serum-induced cyclooxygenase-2 (COX-2) expression [1]. Here, we explored the mechanisms for activation of apoptosis, evaluated the impact on inflammatory genes in a broader panel
