The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

Structural and functional characterization of sulfurtransferase from Frondihabitans sp. PAMC28461.

PLoS ONE
Sulfurtransferases transfer of sulfur atoms from thiols to acceptors like cyanide. They are categorized as thiosulfate sulfurtransferases (TSTs) and 3-mercaptopyruvate sulfurtransferases (MSTs). TSTs transfer sulfur from thiosulfate to cyanide, producing

Sequential Accumulation of ‘Driver’ Pathway Mutations Induces the Upregulation of Hydrogen-Sulfide-Producing Enzymes in Human Colonic Epithelial Cell Organoids

Antioxidants, 2022
Recently, a CRISPR-Cas9 genome-editing system was developed with introduced sequential ‘driver’ mutations in the WNT, MAPK, TGF-β, TP53 and PI3K pathways into organoids derived from normal human intestinal epithelial cells.

Targeting miR‐124‐3p to Induce Antidepressant‐Like Effects in Female Mice: MicroRNA Modulation of Stress Resilience

European Journal of Neuroscience, Volume 64, Issue 2, July 2026.
miR‐124‐3p mimic reduced immobility in the Porsolt swim test in female mice. Proteomics revealed region‐specific changes in hippocampus, hypothalamus and PFC. Downregulation of immune and stress‐related proteins in hippocampus and hypothalamus. Upregulation of synaptic and metabolic proteins in the prefrontal cortex.

Sulfur Administration in Fe–S Cluster Homeostasis

Antioxidants, 2021
Mitochondria are the key organelles of Fe–S cluster synthesis. They contain the enzyme cysteine desulfurase, a scaffold protein, iron and electron donors, and specific chaperons all required for the formation of Fe–S clusters.

Dietary Ergothioneine as a Novel Anti‐Aging Nutraceutical: Mechanisms, Bioavailability, and Future Perspectives

Food Frontiers, Volume 7, Issue 3, May 2026.
ABSTRACT Ergothioneine (EGT), a natural thiol derivative, has gained attention as a geroprotective nutraceutical. Preclinical research shows EGT scavenges free radicals, maintains mitochondrial integrity, slows telomere erosion, and regulates proteostasis via autophagy and senescent cell clearance.

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...
