The expression of the rat cytochrome P450 CYP4 family was studied in hepatic tumors. In most of the primary and transplantable hepatic tumors studied, lauric acid omega-hydroxylase activity associated with the CYP4A subfamily enzymes decreased. The…
The human liver CYP4F2 gene (Accession No. AF221943) encodes a leukotriene B(4) omega-hydroxylase that metabolizes leukotriene B(4) (LTB(4)) to a less potent proinflammatory eicosanoid, 20-OH-LTB(4). We sequenced a 6.7-kb genomic fragment of the…
Activating transcription factor (ATF)3 is known to have an anti-inflammatory function, yet the role of hepatic ATF3 in lipoprotein metabolism or atherosclerosis remains unknown. Here we show that overexpression of human ATF3 in hepatocytes reduces…
