Lifespan‐Extending Endogenous Metabolites

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.

H2O2-Mediated Oxidative Stress Enhances Cystathionine γ-Lyase-Derived H2S Synthesis via a Sulfenic Acid Intermediate

open access: yesAntioxidants, 2021
Hydrogen sulfide (H2S), which is generated mainly by cystathionine γ-lyase (CSE) in the cardiovascular system, plays a pivotal role in a wide range of physiological and pathological processes.

Toxic Tear Gas 2‐Chloroacetophenone (CN) Forms Adducts With Endogenous Plasma Thiols In Vitro Valuable as Biomarkers of Exposure

open access: yesDrug Testing and Analysis, Volume 18, Issue 1, Page 74-84, January 2026.
Incubation of human plasma with the tear gas 2‐chloroacetophenone (CN) led to the formation of acetophenone (AcPhen)‐adducts with the small plasma thiols glutathione, homocysteine, and cysteine persulfide. The AcPhen‐adducts were either bound to an organic thiol‐group or to an organic persulfide. The adducts were detected with a mass spectrometry‐based

Biochemical and Comparative Proteomic Analyses Delineate the Anti‐Ovarian Carcinogenic Roles of Modified Calycosin

open access: yesFood Science &Nutrition, Volume 14, Issue 1, January 2026.
The modified calycosin derivative H10 was more effective in inhibiting cell proliferation through G0/G1 cell cycle arrest, together with inhibiting the migration and colony formation abilities of ovarian cancer cell lines SKOV3 and A2780. Comparative proteomic analysis coupled with Ingenuity Pathway Analysis further delineated calycosin derivative H10 ...

Honokiol ameliorates angiotensin II‐induced hypertension and endothelial dysfunction by inhibiting HDAC6‐mediated cystathionine γ‐lyase degradation

open access: yesJournal of Cellular and Molecular Medicine, 2020
Hypertension and endothelial dysfunction are associated with various cardiovascular diseases. Hydrogen sulphide (H2S) produced by cystathionine γ‐lyase (CSE) promotes vascular relaxation and lowers hypertension.

A Nonketotic Hyperglycinemia Mouse Shows Wide‐Ranging Biochemical Consequences of Elevated Glycine, Reduced Folate One‐Carbon Charging, and Serine Deficiency

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
ABSTRACT Nonketotic hyperglycinemia is a severe neonatal epileptic encephalopathy caused by deficient glycine cleavage enzyme activity, for which currently no effective treatment exists. Incomplete understanding of brain biochemistry represents a major knowledge gap to develop new treatments.

Magnetic Resonance Spectroscopy of Cystathionine and 2‐Hydroxyglutarate in Brain Tumors

open access: yesNMR in Biomedicine, Volume 39, Issue 1, January 2026.
Cystathionine and 2‐hydroxyglutarate were evaluated in 38 glioma patients with TE 97ms PRESS at 3T. Cystathionine level was significantly higher in IDH‐mutant 1p/19q‐codeleted gliomas than in IDH‐mutant non‐codeleted gliomas (p = 0.002). The sensitivity and specificity of the cystathionine measures with respect to 1p/19q status were 0.8 and 0.79, while

Effects of inhibiting antioxidant pathways on cellular hydrogen sulfide and polysulfide metabolism [PDF]

open access: yes, 2019
Elaborate antioxidant pathways have evolved to minimize the threat of excessive reactive oxygen species (ROS) and to regulate ROS as signaling entities.

NRF2 signalling in cytoprotection and metabolism

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 1, Page 101-114, January 2026.
The KEAP1‐NRF2 system plays a central role in cytoprotection in defence mechanisms against oxidative stress. The KEAP1‐NRF2 system has been regarded as a sulfur‐utilizing cytoprotective mechanism, because KEAP1 serves as a biosensor for electrophiles by using its reactive thiols and NRF2 is a transcriptional factor regulating genes involved in sulfur ...
