Apolipoprotein A-II

Apolipoprotein A-II, apoA-II
This gene encodes apolipoprotein (apo-) A-II, which is the second most abundant protein of the high density lipoprotein particles. The protein is found in plasma as a monomer, homodimer, or heterodimer with apolipoprotein D. Defects in this gene may result in apolipoprotein A-II deficiency or hypercholesterolemia.

Pinho et al., São Paulo, Brazil. In Med Microbiol Immunol, Sep 2015
A positive correlation was observed between the blood and hepatic levels of miR-122 in patients infected with HCV genotype 1 (r = 0.302, p = 0.026); in these patients, an inverse correlation was observed between serum apolipoprotein A-II (ApoA-II) levels and the blood (r = -0.330; p = 0.014) and hepatic (r = -0.311; p = 0.020) levels of miR-122.
Effects of Myeloperoxidase-Induced Oxidation on Antiatherogenic Functions of High-Density Lipoprotein.
Tozuka et al., Tokyo, Japan. In J Lipids, Dec 2014
Myeloperoxidase (MPO) secreted by macrophages in atherosclerotic lesions generates tyrosyl radicals in apolipoprotein A-I (apoA-I) molecules, inducing the formation of apoA-I/apoA-II heterodimers through the tyrosine-tyrosine bond in HDL.

Aizawa et al., Tokyo, Japan. In Hepatol Int, Oct 2014
Furthermore, IL28B non-major genotype (rs8099917 TG/GG) was associated with low levels of serum apo B and high levels of apoA-II, and advanced fibrosis was associated with low levels of apo B and C-II in G1b infection.
High-density lipoprotein metabolism, composition, function, and deficiency.
Asztalos et al., Boston, United States. In Curr Opin Lipidol, Jun 2014
SUMMARY: Recent data indicates that proteins other than apoA-I and apoA-II such as MPO and PON1 have important effects on HDL function.
Apolipoprotein A-II is a key regulatory factor of HDL metabolism as appears from studies with transgenic animals and clinical outcomes.

Watts et al., Perth, Australia. In Ann Med, 2012
ApoA-II, a constituent apolipoprotein of certain HDL particles, plays an important role in the regulation of cholesterol efflux, HDL remodelling, and cholesteryl ester uptake via its interactions with lipid transfer proteins, lipases, and cellular HDL receptors.
