aim and background: major depressive disorder (mdd) is known to play a major role in the onset of coronary artery disease (cad). several studies demonstrated an association between dyslipidemia and mdd. the present study aimed to investigate the mean serum lipoproteins and apolipoprotein level in patients with mdd. method and materials: thirty-two patients, who fully met the fourth diagnostic a...

Apolipoprotein B is synthesized by the intestine and the liver in mammals, where it serves as the main structural component in the formation of chylomicrons and very low density lipoproteins, respectively. Apolipoprotein B is also expressed in mammalian fetal membranes. To examine the consequences of apolipoprotein B deficiency in mice, we used gene targeting in mouse embryonic stem cells to ge...

1. Apolipoprotein B-48, the transport protein for chylomicrons, is identical with apolipoprotein B-100 for the first 48% of its sequence. No antiserum has yet been reported that can recognize apolipoprotein B-48, but not apolipoprotein B-100. 2. In the present study an antiserum was raised to the C-terminal sequence of apolipoprotein B-48, using specific chemical reactions to ensure that the ch...

Apolipoprotein B is elevated in growth-retarded compared with normally grown fetuses, demonstrating a link between low birth weight and risk of subsequent atherosclerosis. Increased apolipoprotein B levels and an elevated apolipoprotein B to A-I ratio are predictors of atherogenesis. Elevated apolipoprotein B levels in young adults have been linked to atherosclerosis in later life, whereas impa...

A turbidimetric method is described for the determination of apolipoproteins A-I, A-II and B on microtitre plates. Regression analysis of the resulting values showed a good correlation to apolipoprotein values determined turbidimetrically on Cobas Bio (apolipoprotein A-I, A-II), and those determined by means of radial immuno diffusion (RID) (apolipoprotein A-I: r = 0.93, y = 1.02 x - 5.0, n = 6...

Although some previous studies have suggested that triglyceride, a major core lipid, plays a key role in the assembly and secretion of apolipoprotein B-containing lipoproteins from HepG2 cells, other reports have indicated the importance of cholesteryl ester, another core lipid. We attempted to better define the roles of triglyceride and cholesteryl ester in the assembly and secretion of apolip...
