Hydrogen Sulfide Levels and Nuclear Factor‐Erythroid 2‐Related Factor 2 (NRF2) Activity Are Attenuated in the Setting of Critical Limb Ischemia (CLI)

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2015
Background Cystathionine γ‐lyase, cystathionine β‐synthase, and 3‐mercaptopyruvate sulfurtransferase are endogenous enzymatic sources of hydrogen sulfide (H2S).

Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap

Biology Open, 2015
In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide.

Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria

Advanced Science, EarlyView.
A non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

The effects of hydrogen sulfide synthesis inhibition in lindane-induced seizures in rats: A behavioral and EEG study [PDF]

Archives of Biological Sciences, 2020
Lindane-induced seizure in rats is a model of refractory generalized epilepsy. Hydrogen sulfide (H2S) is a gasotransmitter with different physiological and pathological roles.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Hydrogen sulfide mitigates skeletal muscle mitophagy‐led tissue remodeling via epigenetic regulation of the gene writer and eraser function

Physiological Reports, 2022
Ketone bodies (KB) serve as the food for mitochondrial biogenetics. Interestingly, probiotics are known to promote KB formation in the gut (especially those that belong to the Lactobacillus genus).

Hyperhomocysteinemia and Vitamin B Deficiency as Potential Aggravating Factors in Huntington's Disease: A Prospective Monocentric Study

Movement Disorders, EarlyView.
Abstract Background Although not confirmed, some studies have suggested that elevated homocysteine levels are common in patients with Huntington's disease (HD). Its clinical relevance remains unclear. Objectives We aimed to assess vitamin B and homocysteine levels in HD patients and explore the relationships among hyperhomocysteinemia, vitamin B ...

Cystine rather than cysteine is the preferred substrate for β-elimination by cystathionine γ-lyase: implications for dietary methionine restriction

, 2023
Dietary methionine restriction (MR) increases longevity by improving health. In experimental models, MR is accompanied by decreased cystathionine β-synthase activity and increased cystathionine γ-lyase activity.
