Plasma Apolipoprotein-M (ApoM) Response to a Circuit Resistance Training Program
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...
متن کاملPlasma lipoproteins: apolipoprotein structure and function.
Plasma lipoprotein metabolism is regulated and controlled by the specific apolipoprotein (apo-) constituents of the various lipoprotein classes. The major apolipoproteins include apoE, apoB, apoA-I, apoA-II, apoA-IV, apoC-I, apoC-II, and apoC-III. Specific apolipoproteins function in the regulation of lipoprotein metabolism through their involvement in the transport and redistribution of lipids...
متن کاملIsolation and characterization of human apolipoprotein M-containing lipoproteins.
Apolipoprotein M (apoM) is a novel apolipoprotein with unknown function. In this study, we established a method for isolating apoM-containing lipoproteins and studied their composition and the effect of apoM on HDL function. ApoM-containing lipoproteins were isolated from human plasma with immunoaffinity chromatography and compared with lipoproteins lacking apoM. The apoM-containing lipoprotein...
متن کاملAn apolipoprotein(a) peptide delays chylomicron remnant clearance and increases plasma remnant lipoproteins and atherosclerosis in vivo.
OBJECTIVE Humans with high expression of apolipoprotein(a) [apo(a)] and high plasma levels of lipoprotein(a) [Lp(a)] are at increased risk for atherosclerosis, but the mechanism is not known. We have previously shown that the KIV(5-8) domain of apo(a) has unique cell-surface binding properties, and naturally occurring fragments of apo(a) encompassing this domain are thought to be atherogenic in...
متن کاملComparison of four procedures for separating apolipoprotein A- and apolipoprotein B-containing lipoproteins in plasma.
Because lipoproteins containing apolipoprotein A (ApoA-I + ApoA-II) or apolipoprotein B (ApoB) seem to exert opposite effects as risk factors for coronary heart disease, we decided to determine the separability of these two major plasma lipoproteins by procedures originally designed to separate high-density from low- and very-low-density lipoproteins. The presumably ApoB-free lipoproteins isola...
