Lecithins 74-82 apolipoprotein A1 Homo sapiens 14-21 23516040-1 2013 Existing kinetic data of cholesteryl ester formation by lecithin:cholesterol acyltransferase in discoidal high-density lipoproteins with 34 mutations of apoA-I that involved all putative helices were grouped by cluster analysis into four noncoincident regions with mutations both without any functional impairment and with profound isolated (V- and K-mutations) or common (VK-mutations) effect on V(max)(app) and K(m)(app). Lecithins 56-64 apolipoprotein A1 Homo sapiens 153-159 15882068-11 2005 A fluorescence assay involving dansylated lecithin shows that the suppression is an indirect effect of apo A-I rather than a direct inhibition of PLC enzyme activity. Lecithins 42-50 apolipoprotein A1 Homo sapiens 103-110 3082628-9 1986 These results indicated that apo A-II must be incorporated together with apo A-I into lecithin-cholesterol liposomes to exert its stimulatory effect on LCAT activity and that apo A-II in high-density lipoprotein may play an important role in the regulation of LCAT activity. Lecithins 86-94 apolipoprotein A1 Homo sapiens 29-36 14729075-6 2003 Apo A-I possibly induces the formation of small apo A-I/lecithin/cholesterol complexes of about 5-20 nm similar to the discoidal pre-HDL complexes found in blood when it can no longer effectively shield all the DAG molecules. Lecithins 56-64 apolipoprotein A1 Homo sapiens 0-7 14729075-6 2003 Apo A-I possibly induces the formation of small apo A-I/lecithin/cholesterol complexes of about 5-20 nm similar to the discoidal pre-HDL complexes found in blood when it can no longer effectively shield all the DAG molecules. Lecithins 56-64 apolipoprotein A1 Homo sapiens 48-55 9580110-4 1998 A possible mechanism of the pro-atherogenic action of human apoA-II could be the inhibition of reverse cholesterol transport and, in support of this, we observed an impairment of apoA-I-HDL particle interconversion in the plasma of 11.1 transgenic mice caused, at least in part, by a marked decrease in the endogenous lecithin:cholesterol acyltransferase activity. Lecithins 318-326 apolipoprotein A1 Homo sapiens 60-66 1644835-11 1992 Electron microscopy of the proteoliposome LCAT substrate generated by WT and mutant apoA-I forms showed that the carboxyl-terminal deletion mutants which displayed aberrant binding to HDL also displayed reduced ability to convert the spherical lecithin-cholesterol vesicles into discs compared with WT. Lecithins 244-252 apolipoprotein A1 Homo sapiens 84-90 3126801-0 1987 Formation of mixed micelles and vesicles of human apolipoproteins A-I and A-II with synthetic and natural lecithins and the bile salt sodium taurocholate: quasi-elastic light scattering studies. Lecithins 106-115 apolipoprotein A1 Homo sapiens 50-78 33861588-5 2021 In vitro, MPO-mediated damage of lipid-free apoA-I impaired its ability to promote cellular cholesterol efflux by the ABCA1 pathway, whereas oxidation to lipid-associated apoA-I inhibited lecithin:cholesterol acyltransferase activation, two key steps in reverse cholesterol transport. Lecithins 188-196 apolipoprotein A1 Homo sapiens 44-50 6423754-6 1984 The isoprotein-2 of normal apoA-I and the isoprotein-4 of Tangier apoA-I generate lipid-rich complexes with lecithin, while the isoprotein-2 of Tangier apoA-I shows only a limited association with lipids.

Lecithins 108-116 apolipoprotein A1 Homo sapiens 66-72 6423754-9 1984 This transition was observed for the isoprotein-2 of apoA-I Tangier both in its lipid-free form and in the presence of lecithin. Lecithins 119-127 apolipoprotein A1 Homo sapiens 53-59 6801887-5 1981 These results suggest that apo A-II has a higher affinity than apo A-I for the lecithin-cholesterol vesicle and that 2 mol apo A-II are able to displace 1 mol apo A-I from the apo A-I lipid complexes. Lecithins 79-87 apolipoprotein A1 Homo sapiens 27-34 6801887-5 1981 These results suggest that apo A-II has a higher affinity than apo A-I for the lecithin-cholesterol vesicle and that 2 mol apo A-II are able to displace 1 mol apo A-I from the apo A-I lipid complexes. Lecithins 79-87 apolipoprotein A1 Homo sapiens 63-70 6801887-5 1981 These results suggest that apo A-II has a higher affinity than apo A-I for the lecithin-cholesterol vesicle and that 2 mol apo A-II are able to displace 1 mol apo A-I from the apo A-I lipid complexes. Lecithins 79-87 apolipoprotein A1 Homo sapiens 63-70 170277-12 1975 HDLs were also made by incubating dispersed lecithin or lecithin + cholesterol with Apo-HDL, ApoA-I, or ApoA-II. Lecithins 44-52 apolipoprotein A1 Homo sapiens 93-99 3918999-5 1985 Apo-A-I was a more potent activator than apo-A-IV with egg yolk lecithin, L-alpha-dioleoylphosphatidylcholine, and L-alpha-phosphatidylcholine substituted with one saturated and one unsaturated fatty acid regardless of the substitution position.
