The role of microsomal triglyceride transfer protein in lipoprotein assembly: an update.

Microsomal Triglyceride Transfer Protein and its Role in Apolipoprotein B- Lipoprotein Assembly

Microsomal triglyceride transfer protein and its role in apoB-lipoprotein assembly.

Apolipoprotein B (apoB) and microsomal triglyceride transfer protein (MTP) are necessary for lipoprotein assembly. ApoB consists of five structural domains, betaalpha(1)-beta(1)-alpha(2)-beta(2)-alpha(3). We propose that MTP contains three structural motifs (N-terminal beta-barrel, central alpha-helix, and C-terminal lipid cavity) and three functional domains (lipid transfer, membrane associati...

Anti-hypercholesterolemic Effect of Berbamine Isolated from Rhizoma Coptidis in Hypercholesterolemic Zebrafish Induced by High-Cholesterol Diet

The anti-hypercholesterolemic effect of berbamine (BBM) isolated from Rhizoma Coptidis (RC) was investigated in hypercholesterolemic zebrafish model induced by high-cholesterol (HC) diet. Zebrafish embryo assay revealed no significant difference in morphology and cell death with the treatment of BBM less than 20 μg/mL. In zebrafish larvae, the fluorescently labeled cholesterol in caudal artery ...

Identification and characterization of dual inhibitors for phospholipid transfer protein and microsomal triglyceride transfer protein.

Phospholipid transfer protein (PLTP) plays an important role in atherogenesis and lipoprotein metabolism. PLTP exerts its functions intracellularly and extracellularly. Both PLTP and microsomal triglyceride transfer protein (MTP) have been shown to regulate the secretion of apolipoprotein B (apoB) in hepatocytes. We have previously reported the characterization of inhibitors that selectively in...
