A Mouse Model of Acute and Delayed Complications of Sulfur Mustard Analogue, 2-Chloroethyl Ethyl Sulfide
Background: Numerous studies have been conducted on humans, animals, and cell cultures exposed to Sulfur Mustard (SM). However, the precise mechanism and cause or long-term pattern of SM injuries are not well defined. There is no protocol available for treating people with severe eye, lung, and skin ailments. The current study aimed to develop an animal model of the acute and delayed complicati...
متن کاملCytochrome P450 2S1 is reduced by NADPH-cytochrome P450 reductase.
Cytochrome P450 (P450) 2S1 is one of the orphan P450s without a clear physiological function. Controversy has arisen as to whether it can interact with NADPH-P450 reductase and accept electrons. The reduction of 1,4-bis{[2-(dimethylamino-N-oxide)ethyl]amino}-5,8-dihydroxyanthracene-9,10-dione (AQ4N) by P450 2S1 was confirmed, and the NADPH consumption rates were measured aerobically and anaerob...
متن کاملAirway tissue factor-dependent coagulation activity in response to sulfur mustard analog 2-chloroethyl ethyl sulfide.
Acute lung injury is a principal cause of morbidity and mortality in response to mustard gas (SM) inhalation. Obstructive, fibrin-containing airway casts have recently been reported in a rat inhalation model employing the SM analog 2-chloroethyl ethyl sulfide (CEES). The present study was designed to identify the mechanism(s) causing activation of the coagulation cascade after CEES-induced airw...
متن کاملSelective targeting of selenocysteine in thioredoxin reductase by the half mustard 2-chloroethyl ethyl sulfide in lung epithelial cells.
Thioredoxin reductase (TrxR) is a selenocysteine-containing flavoprotein that catalyzes the NADPH-dependent reduction of oxidized thioredoxin and plays a key role in regulating cellular redox homeostasis. In the present studies, we examined the effects of 2-chloroethyl ethyl sulfide (CEES), a model sulfur mustard vesicant, on TrxR in lung epithelial cells. We speculated that vesicant-induced al...
