Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

open access: yesMedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...

Synthesis and degradation of polyphosphate in the fission yeast Schizosaccharomyces pombe: mutations in phosphatase genes do not affect polyphosphate metabolism.

open access: yes, 1992
The fission yeast Schizosaccharomyces pombe was found to accumulate large amounts of polyphosphate, particularly when grown on arginine as the nitrogen source.

Polyphosphate Affects Key Metabolic Processes in Dictyostelium discoideum [PDF]

open access: yes, 2020
The goal of this project is to determine how physiological levels of polyphosphate affect cellular metabolism in the model organism Dictyostelium discoideum. Understanding the effects of polyphosphate on a molecular level is important, as its activity in

Imaging patterns and genetic associations of brain atrophy across distinct symptom stages in Parkinson's disease

open access: yesNeuroprotection, Volume 4, Issue 3, Page 262-274, September 2026.
Early disease stages showed limited cortical atrophy and enrichment of synaptic and calcium signaling pathways, whereas advanced stages demonstrated widespread cortical degeneration associated with immune activation and extracellular matrix remodeling.

Polyphosphate interaction with aluminium-doped titania pigment particles

open access: yes, 2001
The interaction of a widely used Calgon™ polyphosphate dispersing reagent with aluminium-doped titania pigment particles has been investigated using electrokinetic and rheological studies combined with adsorption isotherms. The influence of pH, aluminium

Structural and functional insights into Pseudomonas aeruginosa ApaH, a diadenosine tetraphosphatase crucial for bacterial virulence

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Infections by Pseudomonas aeruginosa are a major cause of severe morbidity and mortality in immunocompromised patients and people with cystic fibrosis, largely due to the pathogen's ability to resist antibiotic treatment and to deploy multiple virulence strategies that promote persistence in the host.

Structural investigation of nickel polyphosphate coacervate glass-ceramics

open access: yes, 2016
Nickel polyphosphate coacervates have been prepared through the coacervation process of sodium polyphosphate and Ni2+ chloride solutions by the addition of different solvents with low molecular weight.

The Synergy Between a Silver‐Ruthenium Antimicrobial and Aminoglycosides Is Based on Severe Macromolecular Damage

open access: yesMolecular Microbiology, Volume 126, Issue 3, Page 267-282, September 2026.
AGXX enhances aminoglycoside activity against multidrug‐resistant pathogens such as uropathogenic Escherichia coli by increasing reactive oxygen species, causing protein aggregation and DNA damage. This effect is reduced by oxygen limitation or antioxidants. Polyphosphate protects cells from oxidative damage.
