The APOE ɛ2 allele is associated with increased plasma apolipoprotein E levels in patients with coronary artery disease

AimsWe sought to evaluate the influence of APOE polymorphisms (ɛ2-rs7412, ɛ4-rs429358) on plasma levels of apolipoprotein E in patients with confirmed coronary artery disease.MethodsA total of 94 patients with coronary artery disease were included in our study. Genotypisation for rs429358 and rs7412 in APOE was performed and plasma levels of apolipoprotein E, lipids, and hs-CRP were measured.ResultsSignificantly higher plasma levels of APOE were found in the ɛ2 carriers compared to the normal ɛ3/ɛ3 genotype (40.4 mg/mL vs. 22.9 mg/mL, P = 0.018). There was no difference in APOE levels between the ɛ4 allele and ɛ3/ɛ3 allele carriers. Significantly higher HDL cholesterol levels (1.55 mmol/L vs. 1.16 mmol/L, P = 0.001) were found in the ɛ2 carriers, and significantly lower levels of hs-CRP (1.07 mg/L vs. 2.14 mg/L, P = 0.035) in the ɛ4 carriers compared to the normal ɛ3/ɛ3 genotype.ConclusionsIn CAD patients, the ɛ2 APOE allele is associated with significantly higher plasma levels of APOE and HDL cholesterol, whereas the ɛ4 allele is associated with significantly lower levels of hsCRP.     

DHA对APOE4相关阿尔茨海默病影响的研究进展

阿尔茨海默病(AD)是导致老年人痴呆的主要原因。除年龄外,载脂蛋白E (APOE) 4等位基因是散发型AD最强的危险因素。饮食和补充摄入n-3脂肪酸DHA能降低AD的发病风险和改善AD症状。但是相关研究也产生了混乱的和不一致的结果。进一步研究发现,对APOE 4相关AD病人补充DHA的效果可能与补充量和时间、补充对象的疾病严重程度和补充的DHA的形式有关。APOE4携带者在AD临床症状较轻时大高剂量长时间补充DHA是降低AD发病率的有效途径;最好是通过膳食补充磷脂形式的DHA而不是DHA膳食补充。     

Peripheral arterial disease,type 2 diabetes and postprandial lipidaemia: Is there a link?

Peripheral arterial disease, manifested as intermittent claudication or critical ischaemia, or identified by an ankle/brachial index 0.9, is present in at least one in every four patients with type 2 diabetes mellitus.Several reasons exist for peripheral arterial disease indiabetes. In addition to hyperglycaemia, smoking and hypertension, the dyslipidaemia that accompanies type2 diabetes and is characterised by increased triglyceride levels and reduced high-density lipoprotein cholesterol concentrations also seems to contribute to this association. Recent years have witnessed an increased interest in postprandial lipidaemia, as a result of various prospective studies showing that non-fasting triglycerides predict the onset of arteriosclerotic cardiovascular disease better than fasting measurements do. Additionally,the use of certain specific postprandial particle markers,such as apolipoprotein B-48, makes it easier and more simple to approach the postprandial phenomenon. Despite this, only a few studies have evaluated the role of postprandial triglycerides in the development of peripheral arterial disease and type 2 diabetes. The purpose of this review is to examine the epidemiology and risk factors of peripheral arterial disease in type 2 diabetes, focusing on the role of postprandial triglycerides and particles.     

Human apolipoprotein A-I Gly26Arg stimulation of inflammatory responses via NF-kB activation: Potential roles in amyloidosis?

The cascade of molecular events leading to Human apolipoprotein A–I (apoA–I) amyloidosis is not completely understood, not even the pathways that determine clinical manifestations associated to systemic protein deposition in organs such as liver, kidney and heart. About twenty natural variants of apoA–I were described as inducing amyloidosis, but the mechanisms driving their aggregation and deposition are still unclear. We previously identified that the mutant Gly26Arg but not Lys107-0 induced the release of cytokines and reactive oxygen species from cultured RAW 264.7 murine macrophages, suggesting that part of the pathogenic pathway could elicit of an inflammatory signal. In this work we gained deep insight into this mechanism and determined that Gly26Arg induced a specific pro-inflammatory cascade involving activation of NF-κB and its translocation into the nucleus. These findings suggest that some but not all apoA–I natural variants might promote a pro-oxidant microenvironment which could in turn result in oxidative processing of the variants into a misfolded conformation.
