Adrenomedullin-RAMP2 System Suppresses ER Stress-Induced Tubule Cell Death and Is Involved in Kidney Protection
Various bioactive peptides have been implicated in the homeostasis of organs and tissues. Adrenomedullin (AM) is a peptide with various bioactivities. AM-receptor, calcitonin-receptor-like receptor (CLR) associates with one of the subtypes of the accessory proteins, RAMPs. Among the RAMP subisoforms, only RAMP2 knockout mice ⁻/⁻ reproduce the phenotype of embryonic lethality of AM⁻/⁻, illustrat...
متن کاملVascular endothelial adrenomedullin-RAMP2 system is essential for vascular integrity and organ homeostasis.
BACKGROUND Revealing the mechanisms underlying the functional integrity of the vascular system could make available novel therapeutic approaches. We previously showed that knocking out the widely expressed peptide adrenomedullin (AM) or receptor activity-modifying protein 2 (RAMP2), an AM-receptor accessory protein, causes vascular abnormalities and is embryonically lethal. Our aim was to inves...
متن کاملAdrenomedullin is involved in the progression of colonic adenocarcinoma.
Adrenomedullin (ADM), initially identified in human pheochromocytoma, participates in a wide range of physiological and pathological processes, including vasorelaxation, angiogenesis and apoptosis. Recent studies have reported that ADM protected tumor cells against apoptotic cell death via the upregulation of Bcl-2 or the activation of the phospha...
متن کاملAdrenomedullin: angiogenesis and gene therapy.
Adrenomedullin (AM) is a potent, long-lasting vasodilator peptide that was originally isolated from human pheochromocytoma. AM signaling is of particular significance in endothelial cell biology since the peptide protects cells from apoptosis, promotes angiogenesis, and affects vascular tone and permeability. The angiogenic effect of AM is mediated by activation of Akt, mitogen-activated protei...
متن کاملThe GPCR modulator protein RAMP2 is essential for angiogenesis and vascular integrity.
Adrenomedullin (AM) is a peptide involved both in the pathogenesis of cardiovascular diseases and in circulatory homeostasis. The high-affinity AM receptor is composed of receptor activity-modifying protein 2 or 3 (RAMP2 or -3) and the GPCR calcitonin receptor-like receptor. Testing our hypothesis that RAMP2 is a key determinant of the effects of AM on the vasculature, we generated and analyzed...
