Abstract:
We previously demonstrated that treatment with BemA (bempedoic acid), an inhibitor of ATP citrate lyase, significantly reduces fatty liver in a model of liver steatosis (HFHFr—female Sprague-Dawley rat fed a high-fat high-fructose diet). Since the hepatic production of the gasotransmitter H2S is impaired in liver disorders, we were interested in determining if the production of H2S was altered in our HFHFr model and whether the administration of BemA reversed these changes. We used stored liver samples from a previous study to determine the total and enzymatic H2S production, as well as the ex

Abstract:
The saphenous vein is the conduit of choice for bypass grafting. Unfortunately, the hemodynamic stress associated with the arterial environment of the bypass vein graft leads to the development of intimal hyperplasia (IH), an excessive cellular growth and collagen deposition that results in restenosis and secondary graft occlusion. Hydrogen sulfide (H2S) is a ubiquitous redox-modifying gasotransmitter that inhibits IH. H2S is produced via the reverse trans-sulfuration pathway by three enzymes: cystathionine γ-lyase (CSE), cystathionine β-synthase (CBS) and 3-mercaptopyruvate sulfurtransferase

Abstract:
Cystathionine gamma-lyase (CSE) and TNF-α are now recognized as key regulators of intestinal homeostasis, inflammation, and wound healing. In colonic epithelial cells, both molecules have been shown to influence a variety of biological processes, but the specific interactions between intracellular signaling pathways regulated by CSE and TNF-α are poorly understood. In the present study, we investigated these interactions in normal colonocytes and an organoid model of the healthy human colon using CSE-specific pharmacological inhibitors and siRNA-mediated transient gene silencing in analytical

Abstract INTRODUCTION Current combination therapies in ulcerative colitis (UC) target different inflammatory cascades, including tumor necrosis factor-alpha (TNF-alpha) signaling. However, most patients do not achieve long-term remission, suggesting that the molecular pathophysiology of UC is still poorly understood. Endogenously produced hydrogen sulfide (H2S) has emerged as a critical physiological mediator of gastrointestinal homeostasis, limiting mucosal inflammation and promoting tissue healing in response to epithelial injury.

Abstract:
Cystathionine-y-lyase (CSE) is a critical enzyme for hydrogen sulfide (H2S) biosynthesis and plays a key role in respiratory syncytial virus (RSV) pathogenesis. The transcription factor NRF2 is the master regulator of cytoprotective and antioxidant gene expression, and is degraded during RSV infection. While some evidence supports the role of NRF2 in CSE gene transcription, its role in CSE expression in airway epithelial cells is not known. Here, we show that RSV infection decreased CSE expression and activity in primary small airway epithelial (SAE) cells, while treatment with tert-butylhydro

Aims: Hydrogen sulfide (H2S) inhibits the proliferation of vascular smooth muscle cells (VSMCs). However, how cystathionine-gamma-lyase (CSE), a major enzyme that produces H2S, is regulated remains unknown. Whether calcium-sensing receptor (CaSR) inhibits the proliferation of VSMCs by regulating the endogenous CSE/H2S pathway in diabetic rat has not been previously investigated. Methods and Results: The morphological and ultrastructure alterations were tested by transmission electron microscopy, changes in the H2S concentration and the relaxation of the mesenteric secondary artery loop of diab

Abstract:
Cystathionine-γ-lyase (CSE) is a hydrogen sulfide (H2S)-synthesizing enzyme that promotes inflammation by upregulating H2S in sepsis. Liver sinusoidal endothelial cells (LSECs) are fenestrated endothelial cells (liver sieve) that undergo alteration during sepsis and H2S plays a role in this process. Substance P (SP) is encoded by the preprotachykinin A (PPTA) gene, and promotes inflammation in sepsis; however, its regulation by H2S is poorly understood. Furthermore, the interaction between H2S and SP in modulating LSEC fenestrations following sepsis remains unclear. This study aimed to investi
