Cystathionine γ-lyase deficiency enhances airway reactivity and viral-induced disease in mice exposed to side-stream tobacco smoke.

Summary of "Cystathionine γ-lyase deficiency enhances airway reactivity and viral-induced disease in mice exposed to side-stream tobacco smoke."

Environmental tobacco smoke (ETS) is a known risk factor for severe respiratory syncytial virus (RSV) infections, yet the mechanisms of ETS/RSV comorbidity are largely unknown. Cystathionine γ-lyase regulates important physiological functions of the respiratory tract.

Discovery of a Bioactive Inhibitor with a New Scaffold for Cystathionine γ-Lyase.

We identify three submicromolar inhibitors with new chemical scaffolds for cystathionine γ-lyase (CSE) by a tandem-well-based high-throughput assay. NSC4056, the most potent inhibitor with an IC of 0...

Cystathionine-γ-lyase expression is associated with mitochondrial respiration during sepsis-induced acute kidney injury in swine with atherosclerosis.

Sepsis is associated with disturbed glucose metabolism and reduced mitochondrial activity and biogenesis, ultimately leading to multiple organ dysfunction, e.g., acute kidney injury (AKI). Cystathioni...

Hydrogen sulfide attenuates paraquat-induced epithelial-mesenchymal transition of human alveolar epithelial cells through regulating transforming growth factor-β1/Smad2/3 signaling pathway.

Exogenous H S donor, sodium hydrosulfide (NaHS), can influence the bleomycin-induced pulmonary fibrosis by attenuating the epithelial-mesenchymal transition (EMT) of alveolar epithelial cells, but whe...

Comparison of multi-walled carbon nanotube and nitrogen-doped multi-walled carbon nanotube effects on lung function and airway reactivity in rats.

Incorporation of multi-wall carbon nanotubes (MWCNT) into materials has raised concerns about their potential hazards to manufacturing workers. In animal models, airway inflammation and lung fibrosis ...

Short-Term Preoperative Protein Restriction Attenuates Vein Graft Disease via Induction of Cystathionine ϒ-Lyase.

Therapies to prevent vein graft disease, a major problem in cardiovascular and lower extremity bypass surgeries, are currently lacking. Short-term preoperative protein restriction holds promise as an ...

Airway Reactivity in Children Before and After BMT Bone Marrow Transplantation

Background: Stem cell transplantation (SCT) is associated with pulmonary complications and may lead to high morbidity and mortality. We encountered several children post-SCT with a clinica...

Medical and Biotech [MESH] Definitions

A multifunctional pyridoxal phosphate enzyme. In the final step in the biosynthesis of cysteine it catalyzes the cleavage of cystathionine to yield cysteine, ammonia, and 2-ketobutyrate. EC 4.4.1.1.

A multifunctional pyridoxal phosphate enzyme. In the second stage of cysteine biosynthesis it catalyzes the reaction of homocysteine with serine to form cystathionine with the elimination of water. Deficiency of this enzyme leads to HYPERHOMOCYSTEINEMIA and HOMOCYSTINURIA. EC 4.2.1.22.

Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).

A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).

An induced state of non-reactivity to grafted tissue from a donor organism that would ordinarily trigger a cell-mediated or humoral immune response.
