The purpose of this study was to determine the effect of chronic (1 wk) feeding of dietary triacylglycerol (TG) of varying fatty acid composition on small intestinal and hepatic apolipoprotein expression, as well as serum lipid and apolipoprotein concentrations, in newborn swine. Two-day-old female swine were fed one of three diets by gavage with the following lipid composition: medium-chain TG...

Apolipoprotein E (apo E) is a structural constituent of several serum lipoprotein classes. It plays an important role in lipid metabolism by acting as a ligand for low-density lipoprotein (LDL) and chylomicron remnant receptors. Three common alleles called e2, e3 and e4 have been described, which code for three protein isoforms (E2, E3 and E4). The polymorphism is clinically significant, and it...

Lipid-free apolipoprotein (apo) A-I contributes to the reverse transport of cholesterol from the periphery to the liver by solubilizing plasma membrane phospholipid and cholesterol. The features of the apolipoprotein required for this process are not understood and are addressed in the current study. Membrane microsolubilization of human fibroblasts is not specific for apo A-I; unlipidated apos...

Apolipoprotein M (Apo-M) is a human novel protein of apolipoprotein classes and highly expressed in liver and kidney tissues. ApoM is mainly associated with high-density lipoprotein (HDL), and act as a chaperone for sphingosine-1-phosphate (S1P), promotes mobilization of cellular cholesterol, formation of larger-size of pre β-HDL, and a new biomarker in sepsis. The level of apoM in plasma/s...

OBJECTIVE To investigate involvement of specific apolipoproteins in the process of human oocyte maturation and age-related infertility as molecular constituents of follicular fluid. DESIGN Laboratory-based observational study. SETTING Basic science laboratory at a large academic institution. PATIENT(S) Follicular fluid obtained from healthy women aged 18 to 45 years undergoing in vitro fe...

  Abstract   Background: Recently, small dense low density lipoprotein (sdLDL) has been   highlighted as a new risk factor for the coronary artery disease (CAD).Small dense   LDLs are believed to be atherogenic since these particles are taken up more easily by   arterial wall. They are readily oxidized and have reduced affinity for low density   lipoprotein (LDL) receptor and increased affinity...

The interaction of normal and acute-phase high-density lipoproteins of the subclass 3 (N-HDL3 and AP-HDL3) with human neutrophils and the accompanying degradation of HDL3 apolipoproteins have been studied in vitro. The chemical composition of normal and acute-phase HDL3 was similar except that serum amyloid A protein (apo-SAA) was a major apolipoprotein in AP-HDL3 (approx. 30% of total apolipop...

The influence of different fibrates on apolipoprotein metabolism was investigated. Administration of fenofibrate provoked a dose-dependent decrease in plasma cholesterol concentration that was already evident after 1 day. Intestinal apolipoprotein (apo) A-I and apo A-IV mRNA levels remained fairly constant. In contrast, liver apo A-I, apo A-II, and apo A-IV mRNA levels decreased in a dose-depen...

Body Mass Index (BMI) is a simple way to monitor weight. Overweight as result of excessive body fat accumulation which characterized by decrease in HDL (High-Density Lipoprotein), namely the atherogenic side represented levels Apolipoprotein AI (ApoA-I), increased triglycerides (TG), VLDL (Very Low-Density Lipoprotein). ), LDL (Low-Density and Total Cholesterol anti-atherogenic B (Apo-B). If we...

Aim: To determine the association between serum and aqueous apolipoprotein (Apo) A1 Apo B levels B/A1 ratio in diabetic retinopathy.
 Material Method: This cross-sectional prospective study included 63 patients with or without retinopathy 38 control subjects who underwent cataract surgery. The groups were as follows; healthy (Group 1), 2), non-proliferative 3), proliferative 4). Serum dete...
