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

Hypertension and Aging Affect Liver Sulfur Metabolism in Rats

Cells, 2021
Hypertension and age are key risk factors for cardiovascular morbidity and mortality. Hydrogen sulfide (H2S), a gaseous transmitter, contributes significantly to regulating arterial blood pressure and aging processes.

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 Signaling Axis as a Target for Prostate Cancer Therapeutics

Prostate Cancer, 2016
Hydrogen sulfide (H2S) was originally considered toxic at elevated levels; however just in the past decade H2S has been proposed to be an important gasotransmitter with various physiological and pathophysiological roles in the body.

CTH/MPST double ablation results in enhanced vasorelaxation and reduced blood pressure via upregulation of the eNOS/sGC pathway

Frontiers in Pharmacology, 2023
Hydrogen sulfide (H2S), a gasotransmitter with protective effects in the cardiovascular system, is endogenously generated by three main enzymatic pathways: cystathionine gamma lyase (CTH), cystathionine beta synthase (CBS) and 3-mercaptopyruvate ...

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.

Methionine Restriction Extends Yeast Lifespan by Activating Non‐Nitrogen‐Starvation‐Induced Autophagy Through Limiting Methylation of Protein Phosphatase 2A

Aging Cell, Volume 25, Issue 6, June 2026.
Methionine restriction extends yeast replicative and chronological lifespan as a consequence of depletion of S‐adenosylmethionine (SAM). SAM depletion leads to demethylation of PP2A and increased phosphorylation of Npr2 which activates non‐nitrogen‐starvation (NNS) induced autophagy; early methionine restriction is sufficient to activate persistent ...

Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

The Journal of Physiology, Volume 604, Issue 11, Page 4247-4260, 1 June 2026.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.
