H2S Donors Reverse Age-Related Gastric Malfunction Impaired Due to Fructose-Induced Injury via CBS, CSE, and TST Expression

Frontiers in Pharmacology, 2020
ObjectiveExcess of fructose consumption is related to life-treating conditions that affected more than a third of the global population. Therefore, to identify a newer therapeutic strategy for the impact prevention of high fructose injury in age-related ...

MAPK Inhibitor‐Tolerant Persister Cells in Melanoma: Mechanisms and Therapeutic Vulnerabilities

Cancer Science, Volume 117, Issue 8, Page 2050-2063, August 2026.
Melanoma response to MAPK inhibition progresses from drug‐sensitive cells to drug‐tolerant persister states, which enable survival through adaptive signaling, metabolic rewiring, and phenotypic plasticity. These persister cells serve as an intermediate reservoir from which resistant tumors ultimately emerge. ABSTRACT Though major advancements have been

Caenorhabditis elegans and Drosophila melanogaster as Model Organisms in Biofactor Research

BioFactors, Volume 52, Issue 4, July/August 2026.
This review presents Caenorhabditis elegans and Drosophila melanogaster as powerful and ethically sound invertebrate model organisms that can be used to investigate nutritional science questions relating to biofactors. Such nutritional phenotyping studies can bridge the gap between in vitro studies and in vivo research in mammals.

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 ...

Hydrogen Sulfide Reduces Myeloid-Derived Suppressor Cell-Mediated Inflammatory Response in a Model of Helicobacter hepaticus-Induced Colitis

Frontiers in Immunology, 2018
Chronic inflammation contributes to tumor initiation in colitis-associated colorectal cancer (CRC). Indeed, inflammatory bowel disease (IBD) patients show an increased risk of developing CRC.

Cars2‐Mediated Cysteine Catabolism Drives Brown Fat Development and Thermogenesis Through Persulfidating EBF2

Advanced Science, Volume 13, Issue 31, 4 June 2026.
We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

Effect of cysteine on the inactivation of cystathionine gamma-lyase by D,L-propargylglycine.

Acta medica Okayama, 1989
In vivo inactivation of cystathionine gamma-lyase by D,L-propargylglycine, a suicide inhibitor, was found to be less profound in rat kidney than in the liver. We investigated the cause of this difference using rat tissues. We fractionated kidney extract to characterize the substance which protected enzyme, and found that cysteine exhibits protecting ...

Allosteric activators of cystathionine γ lyase to augment endogenous hydrogen sulfide and inhibit pathologic calcification

Pharmacological Research
Hydrogen sulfide (H₂S), a gasotransmitter naturally produced in the body by enzymes such as cystathionine γ lyase (CSE), helps reduce inflammation, oxidative stress, and abnormal tissue calcification.

Hydrogen sulfide and its role in female reproduction

Frontiers in Veterinary Science
Hydrogen sulfide (H2S) is a gaseous signaling molecule produced in the body by three enzymes: cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST).
