RESUMEN

Hydrogen sulfide is a gas signaling molecule in the human body that can influence angiogenesis, regulate tumor cell apoptosis and autophagy, and interact with other signaling molecules in the tumor microenvironment. It plays a role in inhibiting tumorigenesis and development through various pathways. Hydrogen sulfide donors primarily exhibit anti-tumor effects, and many studies are focused on using various donors to release hydrogen sulfide in a controlled manner and maintain therapeutic concentrations. Traditional Chinese medicine shows great potential. The mechanisms of hydrogen sulfide action are complex and diverse, and further research is needed to explore and confirm them, providing a theoretical basis for the development of therapeutic drugs regulating hydrogen sulfide.

RESUMEN

Objective:To investigate the effects of exogenous hydrogen sulfide on myocardial fibrosis and apoptosis in rats after myocardial infarction and the underlying mechanisms.Methods:Forty-three Sprague Dawley(SD)rats were divided into 4 groups according to the random number table method: a control group(n=12), a myocardial infarction group(MI group, n=13), an hydrogen sulfide(H 2S)group(n=6)and an MI+ H 2S group(n=12). The rat model of acute myocardial infarction was established by intraperitoneal injections of isoproterenol(50 mg/kg, once a day, for 2 days). Electrocardiogram and troponin changes were recorded 48 h after the last drug administration to determine whether the rat model was successfully constructed.After successful establishment of the model, rats in the MI group and the MI+ H 2S group were intraperitoneally injected with sodium hydrosulfide(56 μmol/kg, once a day, for 6 weeks).6 weeks later, echocardiogram and Masson's trichrome staining were performed to assess changes in cardiac function and collagen volume fraction in each group.Terminal deoxynucleotidyl transferase(TdT)dUTP nick end labeling(TUNEL)was used to detect the myocardial apoptosis rate in each group, and Western-blot was used to detect protein expression of Yes-related protein 1(YAP1), WW domain containing transcriptional regulator1(TAZ), mammalian Ste20-like kinase 2(MST2), Bcl-2-associated X protein(Bax), cysteine protease 3(caspase-3), the ratio of matrix metalloproteinase 3(MMP3)/matrix metalloproteinase inhibitor 2(TIMP2), and B-cell lymphoma factor(Bcl-2). Results:Compared with the control group, myocardial collagen volume fraction was increased( P<0.05), the myocardial cell apoptosis rate was increased( P<0.05), and myocardial YAP1, TAZ, MST2, Bax, caspase-3 protein expression and MMP3/TIMP2 ratio were increased in the MI group(all P<0.05), while the expression of Bcl-2 protein was decreased( P<0.05). Compared with the MI group, collagen volume fraction and the cardiomyocyte apoptosis rate were significantly decreased in the MI+ H 2S group( P<0.05). Also, protein expression of YAP1(2.406±0.024 vs.2.830±0.063), TAZ(0.964±0.090 vs.1.329±0.018), MST2(0.780±0.082 vs.1.788±0.097), Bax(1.500±0.008 vs.0.613±0.003)and caspase-3(0.620±0.024 vs.0.780±0.012)and the MMP3/TIMP2 ratio were decreased(all P<0.05), while protein expression of Bcl-2 was increased( P<0.05)in myocardial tissue. Conclusions:H 2S can mitigate myocardial fibrosis after myocardial infarction, through inhibiting the activation of the YAP1/TAZ signaling pathway, thus reducing apoptosis of cardiomyocytes.

RESUMEN

@#Sulfane sulfur species in the reactive sulfur species family include hydrogen polysulfides (H2Sn, n ≥2), which play an essential role in physiological regulation and signal transduction. As a redox pair of H2S, H2Sn can be produced through oxidation or enzyme reaction and regulate protein interaction and enzyme activity.Research has revealed that H2Sn, with higher efficiency of protein S-sulfhydration than H2S, may be responsible for some physiological functions previously attributed to H2S.Therefore, real-time detection of H2Sn is crucial for studying its physiological activity and the relationship between H2S and H2Sn.Traditional detection methods, such as mass spectrometry, are not suitable for living organisms as they require tissue cell disruption.Instead, fluorescence probes are often used for in situ real-time detection due to their high sensitivity and specificity and low biological toxicity.This review summarizes the physiological regulatory activity of H2Sn, as well as the design strategy, response mechanism, fluorescence characteristics, and biological applications of H2Sn fluorescent probes based on the structure of the response group, with a prospect of the challenges and developments in this field.

RESUMEN

Gas molecules including hydrogen sulfide, nitric oxide, carbon monoxide, ethylene, hydrogen gas, ammonia, methane, hydrogen cyanide, and sulfur dioxide were the main components of primitive atmosphere on the earth four billion years ago. Nowadays, these gases are viewed as gasotransmitters (GTs) in organisms, namely endogenously gaseous molecules. GTs not only regulate many physiological and pathological processes, such as breathing, blood pressure, learning, memory, and the inflammatory response in animals, but also play a key role in the stomatal movement, seed germination, plant growth, development, and response to environmental stress. In this review, we cover the current progress on the metabolism of GTs, their response to temperature stress in plants, and their general characteristics, anabolism, catabolism. In addition, we highlight the key role of the antioxidant system, the osmoregulation system, the ion balance system, the water balance system, heat shock proteins, post-translational modifications, and re-establishment and repair of biomembranes in the mitigation of oxidative stress, osmotic stress, ion stress, water stress, protein denaturation, and biomembrane injury induced by temperature stress. The alleviation of these injuries could increase the resistance of plants to high temperature and low temperature stresses. Furthermore, we summarize the interactions among GTs by initiating chemical reaction, regulating metabolic enzymes, competing target molecules, and triggering new signaling to modulate temperature stress tolerance in plants. The aim of this review is to drive the rapid progress on GTs in the field of plant biology in the future.

RESUMEN

OBJECTIVE To investigate the inhibitory effect and the possible mechanism of hydrogen sulfide (H2S) on the proliferation of cardiac fibroblasts. METHODS The heart of neonatal SD rats was collected, and cardiac fibroblasts were separated with differential centrifugation. Using sodium hydrosulfide as the donor of H2S, the effects of H2S on the proliferation of cardiac fibroblasts induced by angiotensin Ⅱ (Ang Ⅱ), hydroxyproline content and the expression of sirtuin 3 (SIRT3) protein were detected. After SIRT3 knockdown with siRNA technology, the effects of H2S on the proliferation of cardiac fibroblasts induced by Ang Ⅱ, hydroxyproline content, the expressions of collagen Ⅰ (Col Ⅰ), collagen Ⅲ (Col Ⅲ ) and optic atrophy protein 1 (OPA1) were detected. RESULTS H2S could inhibit the proliferation of Ang Ⅱ-induced cardiac fibroblasts, reduce the content of hydroxyproline and increase the expression of SIRT3 (P<0.05). After down-regulating the expression of SIRT3 with siRNA technology, the inhibition of H2S on the proliferation of Ang Ⅱ-induced cardiac fibroblasts and the reduction of hydroxyproline content were both inhibited, and the effect of H2S on reducing the expression of Col Ⅰ and Col Ⅲ and enhancing the expression of OPA1 was also significantly weakened. CONCLUSIONS H2S inhibits the proliferation of Ang Ⅱ -induced cardiac fibroblasts through increasing the expression of SIRT3.

RESUMEN

ABSTRACT Purpose: This study aimed to assess the possible healing effect of combination treatment with a hydrogen sulfide (H2S) donor, sodium hydrosulfide (NaHS) plus tadalafil on partial bladder outlet obstruction (PBOO)-induced bladder dysfunction. Materials and Methods: A total of 75 male Sprague-Dawley rats aged 10-wk and 300-350g were divided into five groups; control; PBOO; PBOO+NaHS (5.6mg/kg/day, i.p., 6-wk); PBOO+tadalafil (2mg/kg/day, oral, 6-wk) and PBOO+NaHS+tadalafil. PBOO was created by partial urethral ligation. 6 weeks after obstruction, the in vitro contractile responses of the detrusor muscle and Western blotting, H2S and malondialdehyde assay were performed in bladder tissues. Results: There was an increase in bladder weight(p<0.001) and a decrease in contractile responses to KCl (p<0.001), carbachol (p<0.01), electrical field stimulation (p<0.05) and ATP (p<0.001) in the detrusor smooth muscle of obstructed rats which was normalized after the combination treatment. Cystathionine γ-lyase and cystathionine β-synthase, and nuclear factor kappa B protein levels did not significantly differ among groups. The obstruction induced decrement in 3-mercaptopyruvate sulfur transferase protein expression(p<0.001) and H2S levels(p<0.01) as well as increment in protein expressions of neuronal nitric oxide synthase (NO, p<0.001), endothelial NOS (p<0.05), inducible NOS(p<0.001), hypoxia-inducible factor 1-alpha (p<0.01), and malondialdehyde levels (p<0.01), when combined treatment entirely normalized. Conclusions: Combination therapy has beneficial effects on bladder dysfunction via regulating both H2S and nitric oxide pathways as well as downregulation of oxidative stress and hypoxia. The synergistic effect of H2S and nitric oxide is likely to modulate bladder function, which supports the combined therapy for enhancing clinical outcomes in men with BPH/LUTS.
