- Ahn C, Jun D, Na J, Choi Y, Kim Y. Alleviation of hepatic fat accumulation by betaine involves reduction of homocysteine via up-regulation of betaine-homocysteine methyltransferase (BHMT). Biochem Biophys Res Commun. 2016;477:440-7 pubmed publisher..The results suggest that the beneficial effect of betaine against hepatic lipid accumulation may be attributed, at least in part, to the depletion of homocysteine via up-regulation of BHMT in hepatocytes. ..
