Total sulfane sulfur bioavailability reflects ethnic and gender disparities in cardiovascular disease

Redox Biology, 2018
Hydrogen sulfide (H2S) has emerged as an important physiological and pathophysiological signaling molecule in the cardiovascular system influencing vascular tone, cytoprotective responses, redox reactions, vascular adaptation, and mitochondrial ...

Inhibition of Prostaglandin Reductase 2, a Putative Oncogene Overexpressed in Human Pancreatic Adenocarcinoma, Induces Oxidative Stress-Mediated Cell Death Involving xCT and CTH Gene Expressions through 15-Keto-PGE2.

PLoS ONE, 2016
Prostaglandin reductase 2 (PTGR2) is the enzyme that catalyzes 15-keto-PGE2, an endogenous PPARγ ligand, into 13,14-dihydro-15-keto-PGE2. Previously, we have reported a novel oncogenic role of PTGR2 in gastric cancer, where PTGR2 was discovered to ...

Investigation of the association of cystathionine gamma-lyase (CTH) and vitamin D-binding protein (GC) genes polymorphisms with preeclampsia in some pregnant women attending prenatal care at a general hospital in Lagos Nigeria

Science World Journal
Preeclampsia is associated with high maternal and foetal morbidity and mortality. Studies have demonstrated that polymorphisms in the genes that regulate vascular dynamics may play vital roles in the development of chronic hypertension and preeclampsia.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, Volume 20, Issue 6, Page 1556-1590, June 2026.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, Volume 16, Issue 5, Page 944-965, May 2026.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

N‐Acetylcysteine‐Loaded Scaffolds and Their Role in Extracellular ROS and Redox‐Related Gene Regulation in Chondrocytes

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
This study develops N‐acetylcysteine‐loaded polycaprolactone fibers for cartilage regeneration to investigate their potential in regulating redox balance. The fibers exhibit antioxidant properties and modulate genes related to glutathione and transsulfuration pathways.

The Impact of Hydrogen Sulfide Regulatory Gene Alterations on Head and neck squamous cell carcinoma prognosis and tumor microenvironment

Egyptian Journal of Medical Human Genetics
Background Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer globally, with high morbidity and mortality due to late-stage diagnoses, treatment resistance, and recurrence. Hydrogen sulfide (H2S) metabolism, primarily regulated

Lifespan‐Extending Endogenous Metabolites

Aging 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.

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

Food 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 ...

CTH Promotes Liver Cancer Progression and Exploratory Evaluation Supports Enhanced Antitumor Activity of PPG Plus GPC3 CAR‐T Cells

Journal of Immunology Research, Volume 2026, Issue 1, 2026.
Although hydrogen sulfide (H2S) is a key regulator in cancer biology, the mechanism by which the H2S‐producing enzyme cystathionine‐γ‐lyase (CTH) functions in hepatocellular carcinoma (HCC) remains elusive. Using the slow‐releasing H2S donor GYY4137, we observed enhanced migration and invasion in HuH7 and HepG2 cells.
