Scientists at St. Jude Children's Research Hospital have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade it.
St. Jude study shows the Prox1 gene is a two-way switch that, if turned off, causes lymphatic endothelial cells to be reprogrammed so that they lose their identity and become more like blood endothelial cells
A group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke, according to a study published today in the journal Atherosclerosis. The works adds to a growing body of evidence that drinking patterns matter as much, if not more, to risk for cardiovascular disease than the total amount consumed.
Researchers have discovered a novel mechanism which regulates the process whereby new blood vessels are formed and wounds heal, including chronic wounds, such as those found in diabetic patients and those suffering from morbid obesity. These findings have implications for the development of new therapeutic approaches to healing damaged blood vessels and building new ones.
Moreover, a plateau effect was observed after 12 weeks, regardless of the dose used.
What is a fruitful way to contain damages caused during an infarction? The answer is: trying to prevent/limit the action of damaging agents and promote the growth of new blood vessels that could help the recovery of damaged sites.
As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke. The works adds to a growing body of evidence that drinking patterns matter as much, if not more, to risk for cardiovascular disease than the total amount consumed. Irregular, heavy drinking pattern clogs blood vessels.
( University of Rochester Medical Center ) As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke, according to a study published today in the journal Atherosclerosis.

Although its been over a decade since endothelial progenitor cells or EPCs, cells that circulate in the blood repairing and replacing the cells that line blood vessels, were identified, the field is still evolving. EPCs are now being studied as biomarkers to assess the risk of future cardiovascular disease and as potential agents for vascular regeneration.
