Melatonin attenuates (-)-epigallocatehin-3-gallate-triggered hepatotoxicity without compromising its downregulation of hepatic gluconeogenic and lipogenic genes in mice. (-)-Epigallocatehin-3-gallate (EGCG), a major constituent of green tea, can ameliorate metabolic syndrome at least in part through reducing gluconeogenesis and lipogenesis. Green tea extracts, of which EGCG is a key constituent, have been used for weight loss in humans. A potential adverse effect of high-dose EGCG or green tea extracts is hepatotoxicity. Melatonin, an endogenous antioxidant with a high safety profile, is effective in preventing various types of tissue damage. ...
