Lipoprotein surface charge influences cholesteryl ester transfer protein (CETP) activity and its association with lipoproteins; however, the relationship between these events is not clear. Additionally, although CETP and its regulator, lipid transfer inhibitor protein (LTIP), bind to lipoproteins, it is not known how the charge density of lipoprotein protein and lipid domains influences these f...
زمینه و هدف: در میان عوامل خطرساز بیماری کرونری قلب، هیپرلیپیدمی از عوامل خطرساز اصلی می باشد. با توجه به نقش هیپرلیپیدمی در بیماری های قلبی- عروقی به عنوان اولین عامل مرگ و میر انسان و انجام مطالعات بسیار کم روی پلی مورفیسم های ژن کلسترول استر ترانسفر پروتیین در ایران، ما در این مطالعه پلی مورفیسم g/a 971- این ژن را در بیماران هیپرلیپیدمی اولیه بررسی نمودیم.روش بررسی: در این مطالعه مورد- شاهدی...
The net transfer of core lipids between lipoproteins is facilitated by cholesteryl ester transfer protein (CETP). We have recently documented CETP deficiency in a family with hyperalphalipoproteinemia, due to a CETP gene splicing defect. The purpose of the present study was to characterize the plasma lipoproteins within the low density lipoprotein (LDL) density range and also the cholesteryl es...
These studies were undertaken to examine the effects of lipoprotein lipase (LPL) and cholesteryl ester transfer protein (CETP) on the transfer of cholesteryl esters from high density lipoproteins (HDL) to very low density lipoproteins (VLDL). Human or rat VLDL was incubated with human HDL in the presence of either partially purified CETP, bovine milk LPL or CETP plus LPL. CETP stimulated both i...
Endotoxin alters the metabolism of lipoproteins, including that of high density lipoprotein (HDL). Cholesteryl ester transfer protein (CETP) facilitates exchange of HDL cholesterol for very low density lipoprotein (VLDL) triglyceride, leading to catabolism of HDL. We investigated the effects of endotoxin and cytokines on CETP in Syrian hamsters. Endotoxin induced a rapid and progressive decreas...
We previously determined that hamster cholesteryl ester transfer protein (CETP), unlike human CETP, promotes a novel one-way transfer of TG from VLDL to HDL, causing HDL to gain lipid. We hypothesize that this nonreciprocal lipid transfer activity arises from the usually high TG/cholesteryl ester (CE) substrate preference of hamster CETP. Consistent with this, we report here that ∼25% of the to...
Cells produce two cholesteryl ester transfer protein (CETP) isoforms, full-length and a shorter variant produced by alternative splicing. Blocking synthesis of both isoforms disrupts lipid metabolism and storage. To further define the role of CETP in cellular lipid metabolism, we stably overexpressed full-length CETP in SW872 cells. These CETP(+) cells had several-fold higher intracellular CETP...
Cholesteryl ester transfer protein (CETP) mediates the transfer of cholesterol esters (CE) from atheroprotective high-density lipoproteins (HDL) to atherogenic low-density lipoproteins (LDL). CETP inhibition has been regarded as a promising strategy for increasing HDL levels and subsequently reducing the risk of cardiovascular diseases (CVD). Although the crystal structure of CETP is known, lit...
High levels of plasma high-density lipoprotein cholesterol (HDL-C) are associated with a decreased risk of cardiovascular disease. Cholesterol ester transfer protein (CETP) facilitates the transfer or cholesteryl esters from HDL to triglyceride-rich lipoproteins, and its inhibition raises HDL-C levels. Accordingly, interest has focused on CETP inhibition to augment current lipid-lowering strate...
Sensitive immunoradiometric (IRMA) and ELISA Supplementary key words sandwich blotting immunoblotting assays for cholesteryl ester transfer protein (CETP) have been native gel electrophoresis prebeta migrating Superose Superdex developed using two different monoclonal antibodies (MAbs). HepG2 cells The MAbs were prepared against human plasma CETP and demonstrated specificity by their inhibition...
