Oxidized LDL lipids as a risk factor for atherosclerosis

University of Turku, Faculty of Medicine, Department of Clinical Medicine, Department of Physical Activity and Health, Paavo Nurmi Centre, Doctoral Programme of Clinical Investigation, University of Turku, Turku, Finland. Annales Universitatis Turkuensis. Medica – Odontologica, Turku, Finland, 2014. Background: Atherosclerosis progression spans an entire lifetime and has a wide pool of risk factors. Oxidized LDL (oxLDL) is a crucial element in the progression of atherosclerosis. As a rather new member in the atherosclerosis risk factor family, its interaction with the traditional pro-atherogenic contributors that occur at different ages is poorly known. Aims: The aim of this study was to investigate oxLDL and its relation to major contributing risk factors in estimating atherosclerosis risk in data consisting mostly of adult men. The study subjects of this study consisted of four different sets of data, one of which contained also women. The age range of participants was 18-100 years and totaled 2337 participants (of whom 69% were men). Data on anthropometric and hormonal parameters, laboratory measures and medical records were assessed during 1998-2009. Results: Obesity was paralleled with high concentrations of oxLDL, which consequentially was reduced by weight reduction. Importantly, successful weight maintenance preserveed this benefit. A shift from insulin sensitivity to insulin resistance increased oxLDL. Smokers had more oxLDL than non-smokers. A combination of obesity and smoking, or smoking and low serum total testosterone,resulted in even higher levels of oxLDL than any of the three conditions alone. Proportioning oxLDL to HDL-c or apoA1 stood out as a risk factor of all-cause mortality in the elderly. Conclusions: OxLDL was associated with aging, androgens, smoking, obesity, insulin metabolism, weight balance and other circulating lipid classes. Through this variety of metabolic environments containing both constant conditions (aging and gender) as well as lifestyle issues, these findings supported an essential and multidimensional role that oxLDL plays in atherosclerosis pathogenesis.

Angiopoietin 2 regulates the transformation and integrity of lymphatic endothelial cell junctions.

Primitive lymphatic vessels are remodeled into functionally specialized initial and collecting lymphatics during development. Lymphatic endothelial cell (LEC) junctions in initial lymphatics transform from a zipper-like to a button-like pattern during collecting vessel development, but what regulates this process is largely unknown. Angiopoietin 2 (Ang2) deficiency leads to abnormal lymphatic vessels. Here we found that an ANG2-blocking antibody inhibited embryonic lymphangiogenesis, whereas endothelium-specific ANG2 overexpression induced lymphatic hyperplasia. ANG2 inhibition blocked VE-cadherin phosphorylation at tyrosine residue 685 and the concomitant formation of button-like junctions in initial lymphatics. The defective junctions were associated with impaired lymph uptake. In collecting lymphatics, adherens junctions were disrupted, and the vessels leaked upon ANG2 blockade or gene deletion. ANG2 inhibition also suppressed the onset of lymphatic valve formation and subsequent valve maturation. These data identify ANG2 as the first essential regulator of the functionally important interendothelial cell-cell junctions that form during lymphatic development.
