Due to the dominating roles that caspases play in the apoptotic cascade, their activities appear to be a primary factor in the death pathway (apoptosis versus oncosis/necrosis) decision. In murine FL5.12 proB lymphocytes, the cellular consequences of acrolein treatment included a lack of typical
Acrolein is an environmental air pollutant that is known to suppress respiratory host defense against infections. The mechanism of the decrease in host defense is not yet clear. In this study, the effects of acrolein on human alveolar macrophages and their function were examined. Acrolein caused
Acrolein, a highly reactive alpha,beta-unsaturated aldehyde, is an omnipresent environmental pollutant. Chronic and acute human exposures occur through exogenous and endogenous sources, including food, vapors of overheated cooking oil, house and forest fires, cigarette smoke, and automobile exhaust.
The iron dependent, programmed cell death, ferroptosis was described first in tumour cells. It showed distinct features from the already known cell death forms such as apoptosis, necrosis and autophagy. The caspase independent cell death could be induced by the depletion of glutathione by erastin or
Allylamine (3-aminopropene) is a specific cardiac toxicant that causes aortic, valvular and myocardial lesions in many species. Myocardial necrosis can be observed 24 h after a single dose. Acute toxicity is believed to involve metabolism of allylamine to highly reactive acrolein (2-propenal).
Four groups of 40 male Sprague-Dawley rats each were exposed by inhalation to target concentrations of 0, 0.1, 1.0, and 3.0 ppm of acrolein 6 h/day, 5 days/week for 3 weeks. Subsequent changes in local pulmonary immunity were determined by examining the number of antibody plaque-forming cells in the
We assessed the in vitro toxicity of the cardiovascular toxicant allylamine, and its presumed in vivo metabolite, acrolein. In dose-response experiments, rat hearts perfused with allylamine (10-30 mM) or acrolein (0.01-3.0 mM) for 2 hr were assessed by standard histopathology and assay of creatine
Allyl acetate, allyl alcohol, and acrolein are used in the manufacture of detergents, plastics, pharmaceuticals, and chemicals and as agricultural agents and food additives. Male and female F344/N rats and B6C3F(1) mice received allyl acetate, allyl alcohol, or acrolein by gavage for 14 weeks.
Acrolein is a highly toxic, reactive, and irritating aldehyde that occurs as a product of organic pyrolysis, as a metabolite of a number of compounds, and as a residue in water when used for the control of aquatic organisms. It is an intermediate in the production of acrylic acid, DL-methionine, and
OBJECTIVE
To examine the effects of YM976, a phosphodiesterase (PDE)4 inhibitor, on mucin hypersecretion of airway stimulated with acrolein.
METHODS
Forty-eight SD rat were randomly divided into 6 equal groups. Twenty-four rats underwent gastric perfusion of YM976 0.5, 1.5, or 4.5 mgxkg(-1)xd(-1)
Cigarette smoke is a potent inhibitor of pulmonary T cell responses, resulting in decreased immune surveillance and an increased incidence of respiratory tract infections. The alpha,beta-unsaturated aldehydes in cigarette smoke (acrolein and crotonaldehyde) inhibited production of interleukin-2
Environmental triggers of dilated cardiomyopathy are poorly understood. Acute exposure to acrolein, a ubiquitous aldehyde pollutant, impairs cardiac function and cardioprotective responses in mice. Here, we tested the hypothesis that chronic oral exposure to acrolein induces inflammation and
Cigarette smoke is a strong and independent risk factor for esophageal cancer, while the consumption of cow's milk has been proposed as a protective factor. The mechanistic role of milk in preventing cancer, however, has not been clarified. We focused our study on acrolein, an abundant unsaturated
This article presents a mode of action (MOA) analysis that identifies key mechanisms in the respiratory toxicity of inhaled acrolein and proposes key acrolein-related toxic events resulting from the inhalation of tobacco smoke. Smoking causes chronic obstructive pulmonary disorder (COPD) and
The Dahl selected rat lines, one susceptible to salt-induced hypertension (DS) and the other resistant to salt-induced hypertension (DR), were subchronically exposed to filtered air, 0.4, 1.4, or 4.0 ppm acrolein. All of the DS rats exposed to 4.0 ppm acrolein died within the first 11 days, while
