Vascular endothelial growth factor (VEGF) not only regulates angiogenesis, vascular permeability, and vasodilation but also promotes vascular inflammation. However, the molecular basis for the proinflammatory effects of VEGF is not understood. We now show that VEGF activates endothelial cell exocytosis of Weibel-Palade bodies, releasing vasoactive substances capable of causing vascular thrombos...

The embryonic vasculature develops from endothelial cells that form a primitive vascular plexus which recruits smooth muscle cells to form the arterial and venous systems. The MADS-box transcription factor MEF2C is expressed in developing endothelial cells and smooth muscle cells (SMCs), as well as in surrounding mesenchyme, during embryogenesis. Targeted deletion of the mouse MEF2C gene result...

SARS-CoV-2 was firstly found in bronchoalveloar lavage (BAL) of three suspected COVID-19 patients at Jinyintan Hospital, Wuhan, Hubei Province, China. The cases are still raisingwith2,12% global mortality rate. Hypoxic respiratory failure due to acute distress syndrome (ARDS) is the main cause death. Endothelial cell damage has an important role pathogenesis ARDS and multi-organ dysfuntion pati...

Studies with cGMP-dependent protein kinase I (cGK-I)-deficient human cells and mice demonstrated that cGK-I ablation completely disrupts the NO/cGMP pathway in vascular tissue, which indicates a key role of this protein kinase as a mediator of the NO/cGMP action. Analysis of the vasodilator-stimulated phosphoprotein phosphorylated at serine 239 (P-VASP) is a useful tool to monitor cGK-I activat...

background: a hemangioma is a rather common benign soft tissue tumor that rarely originates from both the pectoralis muscle and the breast. vascular tumors of the breast, such as benign hemangiomas, are rarely seen in men. case presentation: a 40-year-old man presented with a non-tender palpable right breast mass since 6 months ago. on physical examination, a hard lump was detected in the centr...

Ovarian hyperstimulation syndrome is the most serious iatrogenic complication resulting from ovarian stimulation. Currently there is no clear evidence of absolute efficacy for most of standard preventive and curative methods. Recent studies indicate that human chorionic gonadotropin increases vascular endothelial growth factor, vascular endothelial cadherin and vascular permeability via endothe...
