Changes in expressions of up- and downstream thiol cascade were studied in leaves of Phaseolus vulgaris L. cv. VL-63 and its mutant, pvsod1 (deficient in superoxide dismutase activity) under 50 μM sodium arsenate (As), As + L-buthionine-sulfoximine (BSO) and As + BSO + Sodium hydrosulfide (NaHS)-treatments for 10 days. Main objective was to investigate the functional relationship between hydrog...
Hydrogen sulfide (H2S) is a cell signal molecule produced endogenously and involved in regulation of tolerance to biotic and abiotic stress in plants. In this work, we used molecular biology, physiology, and histochemical methods to investigate the effects of H2S on cadmium- (Cd-) induced cell death in Chinese cabbage roots. Cd stress stimulated a rapid increase of endogenous H2S in roots. Addi...
Methyl jasmonate (MeJA), a vital cellular regulator, mediates diverse developmental processes and defense responses against environmental stresse. Recently, a novel gasotransmitter, hydrogen sulfide (H2S), was found to have similar functions, but the interactions between H2S and MeJA in the acquisition of cadmium (Cd) tolerance have not been reported. Treating foxtail millet with 1 microM MeJA ...
BACKGROUND Hydrogen sulfide (H2S) is known to exert anti-inflammatory properties. Apoptosis and autophagy play important roles in concanavalin A (Con A)-induced acute hepatitis. The purpose of this study was to explore both the effect and mechanism of H2S on Con A-induced acute hepatitis. METHODS BALB/c mice were randomized into sham group, Con A-injection group, and 14 μmol/kg of sodium hydr...
Peripheral artery disease (PAD) may lead to a poor quality of life. Although percutaneous transluminal angioplasty (PTA) is widely used for the treatment of PAD, restenosis remains a major drawback. Hydrogen sulfide (H2S) plays potential roles in many physiological processes, such as vasodilatation and inhibition of smooth muscle cell proliferation. However, little is known regarding its role i...
Aminoglycoside antibiotics such as gentamicin could cause ototoxicity in mammalians, by inducing oxidative stress and apoptosis in sensory hair cells of the cochlea. Sodium hydrosulfide (NaHS) is reported to alleviate oxidative stress and apoptosis, but its role in protecting aminoglycoside-induced hearing loss is unclear. In this study, we investigated the anti-oxidant and anti-apoptosis effec...
There is growing evidence that oxidative stress plays critical roles in the pathogenesis of cardiac remodeling. In the present study, we established a rat model of passive smoking and investigated the antioxidant effects of hydrogen sulfide (H2S) on smoking-induced left ventricular remodeling. Cardiac structure and function were evaluated using 2-dimensional echocardiography. Myocardial fibrosi...
Cardiac hypertrophy is a critical component of phenotype in the failing heart. Recently, increasing evidence has demonstrated that oxidative stress plays an important role in the pathogenesis of myocardial hypertrophy. In the present study, we generated a mouse model of transverse aortic constriction (TAC) to investigate whether hydrogen sulfide (H2S) has protective effects against cardiac hype...
