Previous studies of the authors have indicated that the transplantation of mesenchymal stem cells (MSCs) can attenuate cardiac fibrosis through the secretion of antifibrotic factors, such as adrenomedullin (ADM). Therefore, the authors addressed the hypothesis that ADM overexpression could enhance the antifibrotic effect of MSCs transplantation in a rat model of heart failure. The results of the present study demonstrated that, compared with the group that received the GFP‑MSCs, the transplantation of ADM‑MSCs significantly improved heart function and decreased the percentage of fibrotic area and the expression of matrix metalloproteinase 2...

This report evaluates the protective effect of caffeoylquinic acid (CA) injury to oligodendrocyte precursor cells (OPCs) by promoting the formation of oligodendrocytes. Neonatal rat brain was used to isolate primary OPCs and non-lethal CoCl2 was used to induce hypoxic stress to inhibit the differentiation of OPCs. Differentiation of OPCs was estimated by survival assay and the expressions of myelin-basic-protein (MBP). Moreover, the effect of CA on the Akt signanling pathway was also estimated in the presence and absence of LY294002 (PI3K/Akt inhibitor) and adrenomedullin (AM) receptor antagonist (AM22-52) by using western blot assay...

The current study aimed to improve the understanding on the association between adrenomedullin and osteoporosis in mice with glucocorticoid-induced osteoporosis. Bone resorption and osteoporosis-associated indexes, including maximum load, stiffness, energy to failure, ultimate strength, elastic modulus, post-yield displacement and post-yield displacement, in mice with osteoporosis were analyzed in order to evaluate the effect of adrenomedullin. The receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation was investigated subsequent to treatment with adrenomedullin in vitro...

The calcitonin/calcitonin gene-related peptide (CGRP) family of peptides includes calcitonin, α and β CGRP, amylin, adrenomedullin (AM) and adrenomedullin 2/intermedin (AM2/IMD). Their receptors consist of one of two G protein-coupled receptors (GPCRs), the calcitonin receptor (CTR) or the calcitonin receptor-like receptor (CLR). Further diversity arises from heterodimerisation of these GPCRs with one of three receptor activity-modifying proteins (RAMPs). This gives the CGRP receptor (CLR/RAMP1), the AM1 and AM2 receptors (CLR/RAMP2 or RAMP3) and the AMY1, AMY2 and AMY3 receptors (CTR/RAMPs1-3 complexes, respectively)...

OBJECTIVE: To investigate the role of hypoxia-inducible factor-1α and its target genes in hypoxic pulmonary hypertension in neonates. PATIENTS AND METHODS: A total of 117 newborns were selected and divided into two groups for clinical experiments: 85 cases in the hypoxic pulmonary hypertension (HPH) group, including mild, moderate and severe subgroups, and 32 cases in the case-control group. ELISA was used to detect the serum HIF-1α, endothelin-1 (ET-1) and adrenomedullin (ADM) levels, and echocardiography was used to detect the dynamic changes in pulmonary artery systolic pressure (PASP), right ventricular ejection fraction (RVEF), tricuspid E peak and A peak ratio (E/A) and right ventricular Tei index...

Implantation is a complex event demanding contributions from both embryo and endometrium. Despite advances in assisted reproduction, endometrial receptivity defects persist as a barrier to successful implantation in women with infertility. We previously demonstrated that maternal haploinsufficiency for the endocrine peptide adrenomedullin (AM) in mice confers a subfertility phenotype characterized by defective uterine receptivity and sparse epithelial pinopode coverage. The strong link between AM and implantation suggested the compelling hypothesis that administration of AM prior to implantation may improve fertility, protect against pregnancy complications, and ultimately lead to better maternal and fetal outcomes...

Calcitonin receptor-like receptor (CLR) and the receptor activity-modifying protein 2 (RAMP2) comprise a receptor for adrenomedullin (AM). Although it is known that AM induces internalization of CLR•RAMP2, little is known about the molecular mechanisms that regulate the trafficking of CLR•RAMP2. Using HEK and HMEC-1 cells, we observed that AM-induced activation of CLR•RAMP2 promoted ubiquitination of CLR. A mutant (CLRΔ9KR), lacking all intracellular lysine residues was functional and trafficked similar to the wild-type receptor, but was not ubiquitinated...

INTRODUCTION: Under some circumstances human milk (HM) extraction and refrigerated storage may be necessary. Depending on the length and on the type of cold storage, milk may lose some important properties, but current advices on safe HM storage are discordant. Moreover until now no data in literature were present on the effect of prolonged cold storage on biologically active components of the HM such as adrenomedullin (AM). This important peptide is involved in response to hypoxia and inflammation, associated with neovascularization, in several tissues...

AIM: Stroke is associated closely with vascular homeostasis, and several complex processes and interacting pathways, which involve various genetic and environmental factors, contribute to the risk of stroke. Although adrenomedullin (ADM) has a number of physiological and vasoprotective functions, there are few studies of the ADM receptor system in humans. The ADM receptor comprises a calcitonin-receptor-like receptor (CLR) and receptor activity-modifying proteins (RAMPs). We analyzed single nucleotide polymorphisms (SNPs) in the RAMP2 and CLR genes to determine their association with stroke in the light of gene-environment interactions...

We aimed to evaluate the usefulness of sepsis biomarkers to predict stroke-associated infections. Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1), mid-regional pro-adrenomedullin (MR-proADM), presepsin (sCD14), and soluble urokinase-type plasminogen activator receptor (suPAR), were explored in 125 blood samples collected at different time-points. At baseline, MR-proADM was an independent predictor of infection [>0.94pg/mL, OR=3.63 (1.16-11.33), p=0.026], as well as suPAR at 24h [>2185...

Alzheimer's disease (AD) is characterized by the loss of synaptic contacts caused in part by cytoskeleton disruption. Adrenomedullin (AM) is involved in physiological functions such as vasodilation, hormone secretion, antimicrobial activity, cellular growth, and angiogenesis. In neurons, AM and related peptides are associated with some structural and functional cytoskeletal proteins, causing microtubule destabilization. Here, we describe the relationships between AM and other signs of AD in clinical specimens...

PURPOSE OF REVIEW: This study is to highlight recent discoveries associated with the role of calcitonin peptide family and their receptors in prostate cancer progression and bone metastasis. RECENT FINDINGS: Studies have linked adrenomedullin (AM), calcitonin (CT) and calcitonin gene-related peptide (CGRP) to the spread of prostate tumours to the bone. AM can induce a metastatic phenotype in prostate cancer cells through its action on TRPV2 calcium channels and is also capable of influencing localised levels of RANKL in the bone to favour tumourigenesis...

BACKGROUND: Neuroendocrine responses to orthostasis may be critical in the maintenance of mean arterial pressure in healthy individuals. A greater reduction in orthostatic tolerance with age may relate to modulation of hormonal responses such as adrenomedullin and galanin. Thus, we investigated (i) whether adrenomedullin and galanin concentrations increase during orthostatic challenge in older subjects, (ii) whether adrenomedullin and galanin concentrations are higher in older females compared with older males when seated and during orthostatic challenge, and (iii) whether postural changes in plasma concentrations of galanin are correlated with levels of adrenomedullin in either older females or males...

The control of hypertension and the resulting cardiovascular events is still insufficient. Thus, the search for novel means for blood pressure (BP) reduction remains worth further clinical and research attention. The advances in vector and construct design sketch the use of gene therapy in hypertension. Areas covered: We have searched for studies using gene therapy in hypertension reporting BP outcomes. We have identified 63 experimental studies demonstrating feasible targeting of the classical and new renin-angiotensin-aldosterone system, β1-adrenergic receptor, NO-cGMP axis, endothelin, natriuretic peptides, kallikrein system, cytochrome P-450 hydroxylase, oncogenes, growth factors, interleukins, angiopoietin-1, adrenomedullin or Klotho in small rodents...

Prospective clinical plasma biomarker studies in abdominal aortic aneurysm (AAA) pathogenesis have been hampered by the need for very large cohorts and long follow-up time. The main aim of the present study was to evaluate the association of adrenomedullin, a cardiovascular (CV) stress marker, and incident AAA risk. Prospective longitudinal cohort of middle-aged individuals from the CV cohort of the Malmö Diet and Cancer Study (n = 5551; 1991-1994) was assessed. Plasma concentrations of midregional proadrenomedullin (MR-proADM), C-reactive protein (CRP), and conventional risk factors were measured at baseline...
