it did not impair IL-1beta-induced VEGF synthesis. 7-ketocholesterol 0-7 nitric oxide synthase 2 Rattus norvegicus 22-26 11730812-7 2001 7-Kchol decreased rat iNOS promoter activity, iNOS expression and NO generation, but it did not impair IL-1beta-induced VEGF synthesis. 7-ketocholesterol 0-7 nitric oxide synthase 2 Rattus norvegicus 46-50 11689206-2 2001 We have examined the interaction of recombinant His-tagged caveolin-1 with cholesterol and 7-keto cholesterol, the most abundant non-enzymatically formed oxysterol found in oxidised LDL and atheromatous plaque. 7-ketocholesterol 91-109 caveolin 1 Homo sapiens 59-69 11669638-1 2001 Cholesterol removal from lipid-loaded macrophages is an important, potentially antiatherogenic process, and we have previously shown that an oxysterol,

mononuclear cells to TNF-stimulated HUVEC monolayers was slightly inhibited by 7-ketocholesterol, but this oxysterol did not affect the basal adherence to non-stimulated HUVECs. 7-ketocholesterol 92-109 tumor necrosis factor Homo sapiens 34-37 11325610-10 2001 We conclude that 7-ketocholesterol releases VCAM-1 from the endothelium probably by a proteolytic process. 7-ketocholesterol 17-34

7-ketocholesterol 30-47 cytochrome P450 family 27 subfamily A member 1 Homo sapiens 0-21 10869358-3 2000 We hypothesized and here show that 27-hydroxylated 7-ketocholesterol (270H-7K) is present in human lesions, probably generated by the action of sterol 27-hydroxylase on 7K. 7-ketocholesterol 51-68 cytochrome P450 family 27 subfamily A member 1 Homo sapiens 144-165 10224662-2 1999 7-Ketocholesterol can inhibit cholesterol 7 alpha-hydroxylase, the rate-limiting step in bile acid biosynthesis, as well as strongly inhibiting HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis. 7-ketocholesterol 0-17 cytochrome P450 family 7 subfamily A member 1 Homo sapiens 30-61 10751394-10 2000 Finally, we showed that the lysosomal cholesterol pool in NP-C cells was substantially and preferentially reduced by incubating cells with the oxysterols, 25-hydroxycholesterol and 7-ketocholesterol; these findings suggest a new pharmacological approach to the

10754270-1 2000 Previous investigations of our laboratory have shown that 7-ketocholesterol was a potent inducer of apoptosis involving a release of cytochrome c into the cytosol, and a lipid peroxidation process that could be the consequence of a production of radical oxygen species. 7-ketocholesterol 58-75 cytochrome c, somatic Homo sapiens 133-145 10484610-2 1999 For example, 7-ketocholesterol (7KC) inhibits cholesterol efflux from macrophage foam cells induced by apolipoprotein A-I (apoA-I). 7-ketocholesterol 13-30 apolipoprotein A1 Homo sapiens 103-121 10484610-2 1999 For example, 7-ketocholesterol (7KC) inhibits cholesterol efflux from macrophage foam cells induced by apolipoprotein A-I (apoA-I). 7-ketocholesterol 13-30 apolipoprotein A1 Homo sapiens 123-129

enzyme in cholesterol biosynthesis. 7-ketocholesterol 0-17 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 144-161 10224662-4 1999 However, when tested as a pharmacological cholesterol-lowering agent, inhibition of HMG-CoA reductase was rapidly overcome and the 7-ketocholesterol metabolised. 7-ketocholesterol 131-148 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 84-101 9880570-3 1999

interleukin 1 beta Homo sapiens 93-101 9632680-11 1998 Since 7-oxocholesterol is a potent inhibitor of cholesterol 7alpha-hydroxylase, alternative mechanisms for regulation of bile acid synthesis may exist in human and hamster liver due to production of this metabolite and its potential as an oxysterol. 7-ketocholesterol 6-22 cytochrome P450 family 7 subfamily A member 1 Homo sapiens 48-78 9644113-8 1998 25-OHCh dose-dependently and more efficiently than 7-KCh inhibited murine splenocyte secretion of MAF, which activity was determined by the ability of splenocyte-conditioned medium to

concentration dependent, and the rate of its removal was 50-fold greater for hydroxypropyl-beta-cyclodextrin than for apolipoprotein A-I. 7-ketocholesterol 10-27 apolipoprotein A1 Homo sapiens 159-177 8885139-3 1996 Cholesterol 5 beta-epoxide and 7-ketocholesterol increased the mobilization of 3H-arachidonic acid from prelabelled platelet phospholipids in response to thrombin and collagen.

recent evidence that 7-ketocholesterol and 7-hydroxycholesterol are toxic species in copper-oxidized LDL, inhibition of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase was hypothesized as a mechanism of toxicity. 7-ketocholesterol 32-49 3-hydroxy-3-methylglutaryl-CoA reductase Homo sapiens 131-181 8354276-5 1993 Addition of 7-oxocholesterol to liver microsomes from normal rats in amounts

8354276-8 1993 It is concluded that treatment with the competitive inhibitor 7-oxocholesterol leads to a reduced bile acid biosynthesis and, as a consequence of reduced bile acid inhibition, a compensatory increase in cholesterol 7 alpha-hydroxylase synthesis. 7-ketocholesterol 62-78 cytochrome P450 family 7 subfamily A member 1 Rattus norvegicus 203-234 4055743-9 1985 By contrast,
