2004 FEB 5 - (NewsRx.com & NewsRx.net) -- Glycated compounds spawn angiogenic induction in cultured endothelial cells.
According to a study from Japan, "glycation has been implicated in the endothelial dysfunction that contributes to both diabetes- and aging-associated vascular complications. The aim of the present study was to determine whether Amadori-glycated phosphatidylethanolamine (Amadori-PE), a lipid-linked glycation compound that is formed at an increased rate in hyperglycemic states, affected proliferation, migration and tube formation of cultured human umbilical vein endothelial cells (HUVEC). Amadori-PE at a low concentration of
"Furthermore, stimulation of HUVEC with Amadori-PE resulted in secretion of matrix metalloproteinase 2 (MMP-2), a pivotal enzyme in the initial step of angiogenesis," noted J.H. Oak and colleagues, Tohoku University, Graduate School Life Sciences and Agriculture.
"Our results demonstrated for the first time that Amadori-PE may be an important compound that promotes vascular disease as a result of its angiogenic ...
