The endothelin system in pulmonary and renal vasculopathy: les liaisons dangereuses

European Respiratory Review, 2009
Endothelial cells regulate vascular tone largely by the actions of endothelin-1. Endothelin-1 is a potent vasoconstrictor, with effects that are dependent on the receptors to which it binds as well as their location.

Endothelin‐1 and Endothelin Receptor Antagonists in Cardiovascular Remodeling

Proceedings of the Society for Experimental Biology and Medicine, 1999
Endothelins build a peptide family composed of three isoforms, each of them containing 21 amino acids. Endothelin‐1 is the isoform mainly responsible for any cardiovascular action and therefore the sole scope of this review. Endothelin‐1 is the most potent endogenous vasoconstrictor known; in addition it acts as a potent (co)mitogen.

Clinical, manometric, genetic, and histologic associations in pediatric intestinal pseudo‐obstruction: A case series

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Pediatric intestinal pseudo‐obstruction (PIPO) is a severe bowel motility disorder characterized by impaired propulsion of gastrointestinal contents without mechanical obstruction. PIPO encompasses congenital and acquired disorders, including neuropathies, myopathies, and mesenchymopathies.

The Impact of Methotrexate on Cardiovascular Outcomes in Psoriasis: A Systematic Review and Meta‐Analysis

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Psoriasis is a chronic immune‐mediated inflammatory disease with a global prevalence of 2%–3% and 1.3% in Brazil. It is associated with comorbidities such as obesity, hypertension, and diabetes, all of which contribute to increased cardiovascular risk due to systemic inflammation and endothelial dysfunction.

Therapy of IgA nephropathy: time for a paradigm change

Frontiers in Medicine
Immunoglobulin A nephropathy (IgAN) often has a poor outcome, with many patients reaching kidney failure within their lifetime. Therefore, the primary goal for the treatment of IgAN should be to reduce nephron loss from the moment of diagnosis.

Therapeutic efficacy of TBC3711 in monocrotaline-induced pulmonary hypertension

Respiratory Research, 2011
Background Endothelin-1 signalling plays an important role in pathogenesis of pulmonary hypertension. Although different endothelin-A receptor antagonists are developed, a novel therapeutic option to cure the disease is still needed.

Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

Brain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

British Journal of Pharmacology, EarlyView.
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.
