The New Role of Proprotein Convertase Subtilisin/Kexin Type 9: A Connection of Proprotein Convertase Subtilisin/Kexin Type 9, Apolipoprotein B, and Autophagy
… observed PCSK9 interacted with apolipoprotein B (apoB) and increased apoB production, irrespective of the LDLR.</p> <p>ApoB is the primary structure protein of LDL particle and it also serves as the ligand for the LDL receptor. There is ample evidence showing that the levels of apoB are a better …

THE USE OF REPLICATION-DEFECTIVE ADENOVIRAL VECTORS FOR EXPRESSION OF PRIMORDIAL ATHEROGENIC LIPOPROTEINS IN MICE
The plasma concentration of apolipoprotein B (apoB)-containing lipoproteins is positively associated with several diseases, including atherosclerosis, type 2 diabetes and obesity. Hence, apoB may be a prime target for therapeutic intervention, particularly during its assembly. The molecular events …

Mechanisms behind the lipid-lowering effects of ACTH - Studies in different experimental models
… and direct lipid-lowering effects in man. All apoB-containing lipoproteins, i.e. VLDL, LDL, Lp(a), are reduced by 25-30%. In contrast, levels of HDL increase about 10%. In hepatic cell cultures, ACTH inhibits expression and secretion of apoB. In this thesis we corroborate that the reduced apoB …

The molecular and cellular defect underlying autosomal recessive hypercholesterolemia (ARH) in the first kindred identified in South Africa
… in LDLr binding domain of apolipopreteinB-100 (apoB-100) are rarely encountered and are know as Familial defective apoB-100 (FDB). Several critical proteins are active in the LDL uptake pathway and their deficiencies are now being shown to underlie the rare autosomal recessive forms of …

Impatto del profilo lipidico sulla malattia aterosclerotica in due differenti coorti di pazienti ad alto rischio cardiovascolare
… in the pathogenesis of atherosclerosis. Of note, ApoB-lipoproteins up to only approximately 70 nm in diameter [i.e., chylomicron remnants, smaller very low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), LDL, and lipoprotein(a)] can efficiently cross an intact endothelium, …

IMPACT OF HEPATIC APOLIPOPROTEIN A-IV EXPRESSION ON VLDL PARTICLE EXPANSION, TRIGLYCERIDE SECRETION, AND STEATOSIS
… demonstrated that apoA-IV expression promotes apoB lipoprotein-mediated TG secretion in transfected enterocytes and hepatoma cells. We therefore examined the impact of apoA-IV expression on VLDL particle dynamics in stably transfected McA-RH7777 hepatoma cells. Expression of apoA-IV caused an …

Identification and Characterization of APOBEC1 mRNA Editing Targets: A Transcriptomics Approach
… B mRNA Editing Catalytic polypeptide 1 (APOBEC1) cytidine deaminase is an mRNA editing enzyme that modifies a specific cytidine in the apolipoprotein B (apoB) transcripts of small intestine enterocytes. APOBEC1-mediated cytidine to uridine editing generates an inframe stop codon and …

Caracterización bioquímica y genómica de las respuestas inducidas por lípidos de la dieta durante el desarrollo larvario del lenguado senegalés (Solea senegalensis, Kaup 1858)
… para la apoA-IV, tres parálogos para la apoB, la apoC-I, la apoC-II, dos parálogos para la apoE, cinco parálogos para la apoD y la apo14 en lenguado senegalés. El estudio de sintenia de las apoA, apoC, y apoE ha permitido confirmar que la mayoría de estos genes (excepto la apoA-I) se …

Development of a Passive Immunization Strategy Against Atherosclerosis
… are aldehyde-modified peptide sequences of apoB-100, the main protein in LDL structure. Immunization of atherosclerosis-prone mice with some of the apoB-100 peptides reduced plaque area by up to 60% in the immunized mice compared to controls. We tested the effects of recombinant human IgG1 …

Analyse der Low-Density-Lipoproteine (LDL) : kann die LFE die UZ-Fraktionierung von LDL ersetzen?
… dienten dabei die fraktionsweise gemessenen ApoB- und Chol-Werte. Bei 28 Seren ergab sich in den UZ-Subfraktionen keine Hauptfraktion, sondern eine annähernde Gleichverteilung der Messparameter. Eine Zuordnung entfiel daher für diese Seren. Als UZ-Hauptfraktion wurden dann nur solche Proben …

The effects of moderate exercise on measures of postprandial lipemia
… had no effect on PPTG. With exercise, total apoB IAUC decreased 20% in the whole group, and total cholesterol IAUC decreased 30% in the NW group. MetS subjects maintained significantly higher TG than NW subjects over the day (p<0.001). PPTG in MetS women declined mid-day, and remained low for …

Effects of Vitamin E Supplementation in Late Gestation Cattle and Evaluation of Vitamin E, Cholesterol, and Phospholipid Relationships in Bovine Serum and Serum Lipoproteins
… fraction containing no apolipoprotein B (non-ApoB) from 1-2 weeks pre-calving to calving. Treatment group calves had higher vitamin E concentrations in serum and non-ApoB than control group calves. Treatment did not affect cholesterol or phospholipid concentrations in serum or the lipoprotein …

Apobec-1 Complementation Factor (ACF) Binds and Regulates Multiple RNAs
… through interaction with ARE-Binding Proteins. Apobec-1 Complementation Factor: ACF) was originally identified as a co-factor in ApoB mRNA C to U editing, but has recently been implicated in regulation of mRNA stability as an ARE-Binding Protein. Here we have used tissue culture models with RNA …

Development and application of a novel method to determine large very low density lipoprotein (VLDL1) kinetics
… due to glucose ingestion on VLDL1-TG and -apoB production rates and Intralipid-TG clearance rate. This showed that hepatic VLDL1 production is suppressed in response to hyperinsulinaemia and that the change in Intralipid-TG clearance rate with hyperinsulinaemia correlated significantly with …

Adaptive Immunity in Cardiovascular Disease
… methylglyoxal-modified apolipoprotein B100 (MGO-ApoB100). In the prospective Malmö Diet and Cancer cohort we studied the relation of T helper 1 (Th1) and T helper 2 (Th2) cells to future cardiovacular events. We found that baseline-levels of Th2 cells, but not Th1 cells, were inversely associated …
