Crotonaldehyde is a ubiquitous hazardous pollutant, present in cigarette smoke and automobile exhaust and is endogenously generated by lipid peroxidation. Most of the current studies focus on its lung toxicity. However, there have been few investigations on the cardiac and renal toxicity caused by
Objective: To observe the effect of crotonaldehyde long-term exposure on kidney injury in male rats, and to explore the specific mechanism of toxic action. Methods: 32 specific pathogen free healthy adult male wistar rats were randomly divided into 4 groups with 8 rats in each group: high-,
The cytotoxicity of aldehydes was studied using human primary bronchial epithelial cells (PBEC) cultured at the air-liquid interface (ALI) or under submerged conditions. PBEC were exposed for 30min via the air phase to acrolein (0.1-1mg/m3), crotonaldehyde (1.5-15mg/m3) or hexanal (22-221mg/m3) or
Crotonaldehyde, a highly toxic α, β-unsaturated aldehyde, is a major component of cigarette smoke and a ubiquitous environmental pollutant. Crotonaldehyde exposure is known to have adverse effects on respiratory health, but the underlying mechanisms remain obscure. As alveolar macrophages display
Objective: To observe the effect of long term crotonaldehyde exposure on heart damage in male rats, and to explore the possible mechanism of toxic action. Methods: 24 specific pathogen free healthy male wistar rats were randomly divided into 4 groups with 6 rats in each group. Rats were treated with
Crotonaldehyde is an extremely toxic α,β-unsaturated aldehyde found in cigarette smoke, and it causes inflammation and vascular dysfunction. Autophagy has been reported to play a key role in the pathogenesis of vascular diseases. However, the precise mechanism underlying the role of acute exposure
Crotonaldehyde, a highly toxic α, β-unsaturated aldehyde, is a ubiquitous hazardous pollutant. Because of its extreme toxicity and ubiquity in all types of smoke, most current research focuses on the lung toxicity of such air pollutants. However, the specific mechanism of pulmonary toxicity caused
Crotonaldehyde is a ubiquitous air pollutant in the environment. It is reported to be harmful to the biosystems in vivo and in vitro. The exposure to crotonaldehyde irritates the mucous membranes and induces edema, hyperemia, cell necrosis, inflammation, and acute respiratory distress syndrome in
Crotonaldehyde, a highly toxic α, β-unsaturated aldehyde, is a major component of cigarette smoke and a ubiquitous environmental pollutant. Crotonaldehyde exposure is known to have adverse effects on respiratory health, but the underlying mechanisms remain obscure. To examine the interaction between
Crotonaldehyde is an environment pollutant and lipid peroxidation product. Crotonaldehyde produces adverse effects to humans and serves as a risk factor for human pulmonary diseases. Like acrolein and 4-hydroxynonenal, crotonaldehyde seems likely to alter many cell signaling cascades, including
Crotonaldehyde is a widespread environmental pollutant and lipid peroxidation product. Crotonaldehyde is a risk factor for many diseases (e.g., chronic pulmonary inflammation). However, its toxicity and its mechanism of action have not been thoroughly investigated. The purpose of this study is to
Objective: To observe the lung injury of male rats induced by sub-chronic exposure to crotonaldehyde, and to explore the possible mechanism of injury. Methods: Forty SPF male Wistar rats were randomly divided into control group and 3 groups in each group, and each group received 0.0,
Cigarette smoke (CS) inhalation causes an early inflammatory response in rodent airways by stimulating capsaicin-sensitive sensory neurons that express transient receptor potential cation channel, subfamily V, member 1 (TRPV1) through an unknown mechanism that does not involve TRPV1. We hypothesized
Persistent oxidative stress and excess lipid peroxidation (LPO), induced by inflammatory processes, impaired metal storage, and/or dietary imbalance, cause accumulations and massive DNA damage. This massive DNA damage, along with deregulation of cell homeostasis, leads to malignant diseases.
TRPA1 is a cation channel located on the plasma membrane of many types of human and animal cells, including skin sensory neurons and epithelial cells of the intestine, lungs, urinary bladder, etc. TRPA1 is the major chemosensor that also responds to thermal and mechanical stimuli. Substances that
