BACKGROUND: Scientific evidence for psychological stress as a risk factor for periodontitis is fragmentary relying mostly on either questionnaire-based or biomarker studies. The aim of this study was to investigate Brain Derived Neurotrophic Factor, Substance P, Vasoactive Intestinal Peptide (VIP), Neuropeptide Y (NPY), Calcitonin Gene Related Peptide and Adrenomedullin as well as cortisol in saliva and serum in periodontal health and disease combined with different aspects of stress and possible associations with clinical parameters...

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...

Fungi are of increasing importance in sepsis. However, culture-based diagnostic procedures are associated with relevant weaknesses. Therefore, culture- and next-generation sequencing (NGS)-based fungal findings as well as corresponding plasma levels of β-d-glucan, interferon gamma (INF-γ), tumor necrosis factor alpha (TNF-α), interleukin (IL)-2, -4, -6, -10, -17A, and mid-regional proadrenomedullin (MR-proADM) were evaluated in 50 septic patients at six consecutive time points within 28 days after sepsis onset...

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 1) whether adrenomedullin and galanin concentrations increase during orthostatic challenge in older subjects, 2) whether adrenomedullin and galanin concentrations are higher in older females compared with older males when seated and during orthostatic challenge, and 3) 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...

The molecular mechanisms of pre-eclampsia are being increasingly clarified in animals and humans. With the uncovering of these mechanisms, preventive therapy strategies using chronic infusion of adrenomedullin, vascular endothelial growth factor-121 (VEGF-121), losartan, and sildenafil have been proposed to block narrow spiral artery formation in the placenta by suppressing related possible factors for pre-eclampsia. However, although such preventive treatments have been partly successful, they have failed in ameliorating fetal growth restriction and carry the risk of possible side-effects of drugs on pregnant mothers...

Adrenomedullin has been shown to be overexpressed in many tumors, including gastric cancer tumors; however, its mechanism of action remains unclear. In this study, we examined the role of adrenomedullin in the pathogenesis of gastric cancer. Using clinical specimens and immunohistochemistry, we found that the expression levels of adrenomedullin and its receptors are inordinately elevated as compared to the adjacent non-tumor gastric tissues. We used siRNA gene silencing, in BGC-823 gastric cancer cell lines, to target adrenomedullin genes, and found that increased adrenomedullin expression results in the proliferation of tumor cells, tumor invasion, and metastasis...

Receptor activity-modifying protein 2 (Ramp2) is a single-pass transmembrane protein that heterodimerizes with several family B G-protein coupled receptors to alter their function. Ramp2 has been primarily characterized in association with calcitonin receptor-like receptor (Calcrl, CLR), forming the canonical receptor complex for the endocrine peptide adrenomedullin (Adm, AM). However, we previously demonstrated that Ramp2+/- female mice display a constellation of endocrine-related phenotypes that are distinct from those of Adm+/- and Calcrl+/- mice, implying that RAMP2 has physiological functions beyond its canonical complex...

Calcitonin gene-related peptide (CGRP) or adrenomedullin (AM) receptors are heteromers of the calcitonin receptor-like receptor (CLR), a class B G protein-coupled receptor, and one of three receptor activity-modifying proteins (RAMPs). How CGRP and AM activate CLR and how this process is modulated by RAMPs is unclear. We have defined how CGRP and AM induce Gs-coupling in CLR-RAMP heteromers by measuring the effect of targeted mutagenesis in the CLR transmembrane domain on cAMP production, modeling the active state conformations of CGRP and AM receptors in complex with the Gs C-terminus and conducting molecular dynamics simulations in an explicitly hydrated lipidic bilayer...

BACKGROUND: Intermedin [IMD, adrenomedullin-2 (ADM-2)] attenuates renal fibrosis by inhibition of oxidative stress. However, the precise mechanisms remain unknown. Heme oxygenase-1 (HO-1), an antioxidant agent, is associated with antifibrogenic effects. ADM is known to induce HO-1. Whether IMD has any effect on HO-1 is unclear. Herein, we determined whether the antifibrotic properties of IMD are mediated by induction of HO-1. METHODS: Renal fibrosis was induced by unilateral ureteral obstruction (UUO) performed on male Wistar rats...

Natriuretic peptides, especially B-type natriuretic peptide (BNP), have primarily been regarded as biomarkers in heart failure (HF). However, they are also possible therapeutic agents due to their potentially beneficial physiological effects. The angiotensin receptor-neprilysin inhibitor, sacubitril/valsartan, simultaneously augments the natriuretic peptide system (NPS) by inhibiting the enzyme neprilysin (NEP) and inhibits the renin-angiotensin-aldosterone system (RAAS) by blocking the angiotensin II receptor...

BACKGROUND: Vasopressin and adrenomedullin and their stable by-products copeptin and midregional part of proadrenomedullin (MR-proADM) are promising biomarkers for the development of preeclampsia. However, clinical use is hampered by the lack of trimester-specific reference intervals. We therefore estimated reference intervals for copeptin and MR-proADM in disease-free Dutch women throughout pregnancy. METHODS: Apparently healthy low risk pregnant women were recruited...
