Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

open access: yesMolecular Microbiology, EarlyView.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

CENPT prevents renal cell carcinoma against ferroptosis by enhancing the synthesis of glutathione

open access: yesCell Death and Disease
Cancer is characterized by chromosomal instability (CIN), which leads to tumor heterogeneity and other malignant features. CIN is caused by abnormal centromere and kinetochore function, which results in aneuploidy, rearrangements, and micronucleus ...

Lactate potentiates NMDA receptor currents via an intracellular redox mechanism targeting GluN2B subunits: implications for synaptic plasticity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Astrocyte‐derived lactate enhances neuronal NMDA receptor (NMDAR) function and synaptic plasticity through a redox‐ and CaMKII‐dependent mechanism. Lactate enters neurons via monocarboxylate transporters (MCTs) and is oxidized by lactate dehydrogenase (LDH) to pyruvate, generating NADH and increasing the intracellular NADH/NAD ...

Gamma‐Glutamyl Cysteine Ligase Activity as a Proxy for Human T Cell Function and Drug‐Induced Immunosuppression

open access: yesAdvanced Science
T cell effector functions are critical for immune defense, but their dysregulation can cause diseases like immune exhaustion in cancer and loss of tolerance in autoimmunity.

Postbiotic Supernatants From Psychobiotic Strains Modulate Antioxidant and Serotonergic Responses

open access: yeseFood, Volume 7, Issue 3, June 2026.
Cell‐free postbiotic supernatants obtained from psychobiotic strains exhibit strain‐dependent antioxidant and serotonergic effects. SCFA‐rich metabolites enhance antioxidant protection and modulate serotonin release in enterochromaffin cells, supporting their potential as functional ingredients for gut and brain health.

Quantitative constraint-based computational model of tumor-to-stroma coupling via lactate shuttle

open access: yes, 2015
Cancer cells utilize large amounts of ATP to sustain growth, relying primarily on non-oxidative, fermentative pathways for its production. In many types of cancers this leads, even in the presence of oxygen, to the secretion of carbon equivalents ...

Polymorphism of Glutamate-Cysteine Ligase Subunit Catalytic (GCLC) Gene in Pulmonary Tuberculosis Patients

open access: yesPakistan Journal of Biological Sciences, 2017
The biomarker of oxidative stress in pulmonary tuberculosis patients has not been found. Oxidative stress occurs due to the low level of antioxidants. Single nucleotide polymorphism of glutamate-cysteine ligase subunit catalytic (GCLC) gene namely -129C/T GCLC has been reported to have an association with a risk factor of oxidative stress ...

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,
