Adrenomedullin (ADM) is a vasodilator produced by vascular endothelium and smooth muscle cells. Although plasma ADM levels are increased in patients with hypertension, heart failure, and myocardial infarction, little information exists regarding the microvascular response to ADM in the human heart. In the present study we tested the hypothesis that ADM produces coronary arteriolar dilation in h...

PURPOSE Adrenomedullin (ADM) is a small, secreted peptide often associated with vasodilation. However, ADM can also function as a neurotransmitter/neuromodulator, and studies suggest ADM is upregulated in the eye in several ocular diseases. However, no studies to date have described an ADM signaling pathway in the retina. METHODS PCR, immunocytochemistry, nitric oxide imaging, western blots, ...

Adrenomedullin (ADM) is important for tumor angiogenesis, tumor cell growth, and survival. Under normoxic conditions, the ADM gene was found to produce two alternative transcripts, a fully spliced transcript that produces AM and PAMP peptides and intron-3–retaining transcript that produces a less functionally significant PAMP peptide only. ADM is a well-established hypoxia inducible gene; howev...

Adrenomedullin (ADM), the product of the vascular endothelial and smooth muscle cells, and cardiomyocytes, is considered to be a local factor controlling vascular tone, cardiac contractility and renal sodium excretion. The aim of this article was to review the existing data on the effect of different types of exercise on plasma ADM concentration in healthy men. The results of studies on the eff...

Stromal elements within a tumor interact with cancer cells to create a microenvironment that supports tumor growth and survival. Adrenomedullin (ADM) is an autocrine/paracrine factor produced by both stromal cells and cancer cells to create such a microenvironment. During differentiation of macrophages, ADM is produced in response to pro-inflammatory stimuli and hypoxia. In this study we invest...

Adrenomedullin (ADM), a secretory peptide with multiple functions in physiological to pathological conditions, is upregulated in several human cancers, including brain, breast, colon, prostate, and lung cancer. However, the molecular mechanisms underlying the regulation of ADM expression in cancerous cells are not fully understood. Here, we report that oncostatin M (OSM), a cytokine belonging t...

Adrenomedullin (ADM), a newly identified vasodilating peptide, is reported to be expressed in lungs and have a bronchodilating effect. We hypothesized whether ADM could be involved in the pathogenesis of bronchial asthma. We examined the role of ADM in airway responsiveness using heterozygous ADM-deficient mice (AM+/-) and their littermate control (AM+/+). Here, we show that airway responsivene...

Adrenomedullin (ADM) and proadrenomedullin N-terminal 20 peptide (PAMP) are two vasoactive peptides, which are highly expressed in human adrenal gland. Autoradiography showed the presence of abundant [125I]ADM and [125I]PAMP binding sites in both the outer cortex and medulla of human adrenals. ADM, but not PAMP binding was completely displaced by the specific CGRP1 receptor antagonist CGRP(8-37...

BACKGROUND The use of acellular dermal matrix (ADM) in implant-based immediate breast reconstruction has been increasing. The current ADMs available for breast reconstruction are offered as aseptic or sterile. No published studies have compared aseptic and sterile ADM in implant-based immediate breast reconstruction. The authors performed a retrospective study to evaluate the outcomes of asepti...

Mesoangiobasts are blood vessel-derived stem cells that differentiate into smooth, skeletal, and cardiac muscle cells. We have reported that postnatal aorta-derived mesoangioblasts (ADM) regenerate skeletal muscle and prevent onset of dilated cardiomyopathy in animal models of Duchenne muscular dystrophy. ADM also differentiate into myelinating glial cells, suggesting they are multipotent and c...
