Target Background

May stabilize HDL (high density lipoprotein) structure by its association with lipids, and affect the HDL metabolism.
Gene References into Functions
  1. Weight loss resulted from a reduction of HDL in both APOE-II genotypes. However, in C homozygote carriers, it was shown that HDL3 reduced significantly and leads to a general shift toward larger size HDL subfractions after intervention, while in T allele carriers HDL2 decreased significantly and weight loss leads to shift toward smaller size HDL subfractions. PMID: 28545455
  2. There was a statistically significant interaction between APOA2 polymorphism and dietary fatty acids intake on oxidative stress n patients with type 2 diabetes PMID: 27271094
  3. This study detected a reduced level of heterodimer apoA2-ATQ/AT and a specific apoA2 isoform hypo-processing pattern in the sera of autoimmune pancreatitis patients. PMID: 29481802
  4. In type 2 diabetes mellitus patients, the dietary intake of antiinflammatory fatty acids, such as omega-3 PUFAs and MUFAs, could reduce the inflammatory effects associated with the Apolipoprotein A2 CC genotype. In addition, proinflammatory fatty acids, such as SFAs, could overcome the antiinflammatory effect of the T-allele. PMID: 28359369
  5. data support an SR-B1 nibbling mechanism that is similar to that of streptococcal serum opacity factor, which also selectively removes CE and releases apoAI, leaving an apoAII-rich remnant. PMID: 28373285
  6. A new missense mutation in an Iranian population has a significant association with high-density lipoprotein cholesterol levels. PMID: 26590203
  7. ApoAII-ATQ/AT not only distinguished the early stages of pancreatic cancer from healthy controls but also identified patients at high risk for pancreatic malignancy. PMID: 26549697
  8. Plasma apoB pool size of VLDL containing apoA-II is much smaller than that of VLDL without apoA-II, and this was caused by a very low rate of secretion of this VLDL type into plasma. PMID: 26071654

  16. These data suggest Apo-AII-containing high-density lipoproteins (HDL) formed intrahepatically are likely cholesterol-rich compared to the smaller intracellular lipid-poor Apo A-I HDL. PMID: 23025327
  17. Enrichment of apo A-II in high-density lipoprotein particles has atheroprotective effects and apo A-II may become a target for the treatment of atherosclerosis. PMID: 23241412
  18. We conclude that apoA-II plays a significant role in apoE-associated risk of incident CVD in women with high levels of HDL-C and CRP. PMID: 22723940
  19. APOA2 m265 genotype may be associated with eating behaviours and dietary modulation of plasma ghrelin. PMID: 21386805
