GHRH antagonists support lung endothelial barrier function

GHRH-antagonists in TNBC

“Triple negative breast cancer” (TNBC) represents a subgroup of breast cancers (BC), which do not express receptors for either estrogen or progesterone and which do not overexpress HER-2 receptors. Although this subgroup is characterized by immunohistochemistry, there is a seventy percent overlap with basal-like breast cancers, defined by gene-expression profiling and thus these terms are frequ...

Iloprost improves endothelial barrier function in lipopolysaccharide-induced lung injury.

The protective effects of prostacyclin and its stable analogue iloprost are mediated by elevation of intracellular cyclic AMP (cAMP) leading to enhancement of the peripheral actin cytoskeleton and cell-cell adhesive structures. This study tested the hypothesis that iloprost may exhibit protective effects against lung injury and endothelial barrier dysfunction induced by bacterial wall lipopolys...

Calcium antagonists and endothelial function

Resident Endothelial Cells and Endothelial Progenitor Cells Restore Endothelial Barrier Function After Inflammatory Lung Injury.

OBJECTIVE Disruption of endothelial barrier integrity is a characteristic of many inflammatory conditions. However, the origin and function of endothelial cells (ECs) restoring endothelial barrier function remain unknown. This study defined the roles of resident ECs (RECs) and bone marrow-derived endothelial progenitor cells (BMDEPCs) in endothelial barrier restoration after endotoxemic lung in...

Endothelial barrier function in preeclampsia.

Impaired endothelial barrier function resulting in increased vascular permeability is a characteristic vascular response in preeclampsia, a hypertensive and multiple systemic disorder of human pregnancy. During the last two decades, endothelial function in preeclampsia has been intensively studied and significant progress has been made in understanding the cellular and molecular bases of the al...
