Synthetic Food Colorants and Gut Microbiota: A Systematic Review of Preclinical Studies

open access: yesFood Frontiers, Volume 7, Issue 5, September 2026.
ABSTRACT Growing evidence suggests that industrial food processing, including the excess consumption of food additives, might have a negative impact on human health. Despite regulatory safety evaluations, their impact on gut microbiota remains poorly characterized.

Iron‐Sulfur Cluster Targeting: A Novel Perspective for Treating Alcohol‐Related Lipid Metabolic Diseases

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
Alcohol metabolism induces structural instability of iron‐sulfur clusters through ROS‐mediated oxidative damage and direct covalent modification of acetaldehyde. The iron‐sulfur cluster deficiency drives metabolic reprogramming by inactivating aconitase, accumulating succinate, and impairing tRNA thiolation, thereby promoting hepatic steatosis ...

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 ...

Nitric Oxide in Cancer: Mechanisms, Dual Role, and Therapeutic Strategies

open access: yesMedComm – Oncology, Volume 5, Issue 3, September 2026.
Nitric oxide exerts concentration‐dependent dual roles in cancer, functioning as either a tumor promoter or suppressor. This review comprehensively examines NO's multifaceted regulation of tumor biology, including S‐nitrosylation signaling, metabolic reprogramming, immunemodulation, and therapy resistance, and highlights emerging therapeutic strategies

Tyrosine residues at the substrate binding site in human NQO1 homodimer: Protein conformational dynamics and optimization of substrate binding geometry

open access: yesThe FEBS Journal, Volume 293, Issue 17, Page 5255-5281, September 2026.
Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...
