1 Niacin noncompetitively inhibits DGAT2 but not DGAT1 activity in HepG2 cells. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
2 In this report, using HepG2 cells, we have examined the effect of niacin on the mRNA expression and microsomal activity of diacylglycerol acyltransferase 1 and 2 (DGAT1 and DGAT2), the last committed but distinctly different enzymes for triglyceride synthesis. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
3 Addition of niacin to the DGAT assay reaction mixture dose-dependently (0-3 mM) inhibited DGAT activity by 35-50%, and the IC(50) was found to be 0.1 mM. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
4 Addition of niacin to the DGAT assay reaction mixture dose-dependently (0-3 mM) inhibited DGAT activity by 35-50%, and the IC(50) was found to be 0.1 mM. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
5 A Lineweaver-Burk plot of DGAT inhibition by niacin showed a noncompetitive type of inhibition. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
6 Niacin selectively inhibited DGAT2 but not DGAT1 activity. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
7 Niacin inhibited overt DGAT activity. Niacin diacylglycerol O-acyltransferase 1 Homo sapiens
