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...
BACKGROUND The half of hyperalphalipoproteinemia (HALP) in Japan is caused by CETP gene mutations. Other than two prevalent mutations (D442G and Intron 14 splicing donor site +1G>A), some rare CETP mutations are found in Japanese HALP subjects. METHODS CETP gene analysis of genomic DNA from subjects was performed by restriction fragment length polymorphism (RFLP) and sequencing analysis. Muta...
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...
مقدمه و هدف: بین کلسترول و بیماری کرونری قلب (chd) ارتباط معنی داری وجود دارد. کلستریل استر ترانسفر پروتئین (cetp) نقش مرکزی در متابولیسم لیپوپروتئین ها بازی می کند و نشان داده شده است که پلی مورفیسم های مختلف در ژن این آنزیم، فعالیت آن و پارامترهای لیپیدی خون را تحت تاثیر قرار می دهد. نظر به اینکه اطلاعات کافی در مورد توزیع ژنوتیپی و تاثیرات پلی مورفیسم msp1 بویژه در جمعیت ایرانی وجود ندارد. ب...
Inhibition of cholesteryl ester transfer protein (CETP) lowers plasma low-density lipoprotein cholesterol concentration and raises high-density lipoprotein (HDL) cholesterol, suggesting it might prevent cardiovascular disease (CVD). From the outset, however, the concept has been controversial owing to uncertainty about its effects on HDL function and reverse cholesterol transport (RCT). Althoug...
