APOA2


Also found in: Acronyms.

APOA2

A gene on chromosome 1q21-q23 that encodes apolipoprotein A2, a protein component of high-density lipoprotein (HDL), which is present in plasma as a monomer, homodimer or heterodimer with apolipoprotein D.

Molecular pathology
APOA2 mutations cause apolipoprotein A2 deficiency or hypercholesterolaemia.

Our data show that the intravitreal levels of APOA2 and CP were inhibited in the vitreous humor of patients with PDR in response to IVC, suggesting that these proteins are involved in the development of diabetic retinopathy and that the mechanism of the effects of anti-VEGF treatment occurs via their effects on inflammation, apoptosis, and/or angiogenesis.
Importantly, the APOA2 and CP levels were altered and these proteins may be involved in the pathogenesis of PDR and the mechanism of anti-VEGF treatment.

We investigated the effect of the -265T>C APOA2 polymorphism on fasting plasma lipids, lipoproteins, and particle size in both men and women.
The bioinformatic analysis of the APOA2 gene control (upstream) region indicates the potential for a CEBPA [CCAAT/enhancer binding protein (C/EBP) [alpha]] binding site that is not predicted with the minor C allele.
Since its discovery, APOA2 has been a protein in search of a function (29).
Despite the scarcity of previous data supporting a role of APOA2 in regulating food intake, copious experimental evidence demonstrates a pivotal role of another apolipoprotein, APOA4, as a satiety signal (20, 21, 39, 40).
As these effects were consistently found in both men and women, we suggest a new role for APOA2 in regulating food intake.
