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.

Cystathionine .GAMMA.-lyase activity in the cephamycin C producer Streptomyces lactamdurans.

The Journal of Antibiotics, 1981
Extracts of the cephamycin C producer S. lactamdurans were found to possess cystathionine gamma-lyase activity (E.C. 4.4.1.1). This represents the first demonstration of this enzyme of the reverse transsulfuration pathway in a prokaryotic organism. A likely involvement of reverse transsulfuration in antibiotic synthesis is indicated by the fact that ...

Volatile Sulfur Compounds as a Predictor for Esophagogastroduodenal Mucosal Injury

Gut and Liver, 2008
Background/Aims: Halitosis is a symptom that bothers patients more socially than medically and its pathogenic mechanisms are unclear and treatment armamenterium is limited. Clinicians generally ignored active interventions.

Two-photon ratiometric imaging of endogenous reactive inorganic sulfur species in the cellular cushion toward formaldehyde

Biosensors and Bioelectronics: X, 2023
To address the potential biological relationship between reactive inorganic sulfur species (RISSs) and formaldehyde, the novel two-photon ratiometric RISSs probes (PH-RISSs) were synthesized practically with high selectivity and sensitivity toward RISSs ...

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 ...

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

Smart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...

Exogenous H2S promotes ubiquitin‐mediated degradation of SREBP1 to alleviate diabetic cardiomyopathy via SYVN1 S‐sulfhydration

Journal of Cachexia, Sarcopenia and Muscle, 2023
Background Diabetic cardiomyopathy, a distinctive complication of diabetes mellitus, has been correlated with the presence of intracellular lipid deposits.

Isothiocyanates as Ferroptosis Inducers to Promote Cancer Cell Death

Phytotherapy Research, Volume 40, Issue 8, Page 5119-5131, August 2026.
ABSTRACT Cancer remains a leading cause of global mortality, with the therapeutic efficacy of anticancer drugs often hampered by late diagnosis and the development of chemotherapy resistance. Ferroptosis is an iron‐dependent form of regulated non‐apoptotic cell death driven by lipid peroxidation.
