Host–Pathogen Dual Targeting With Repurposed Drugs Identifies a Synergistic Therapy for Intracellular Staphylococcus aureus

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
A large intracellular drug‐repurposing screen identifies a potent synergy between 5‐fluoro‐2′‐deoxycytidine and rifapentine, acting through dual host–pathogen targeting to reduce Staphylococcus aureus burdens across strains, cell types, and infection models (created with BioRender).

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

MedComm – 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

MedComm – 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,

Insight into mechanism of oxidative DNA damage in angiomyolipomas from TSC patients

Molecular Cancer, 2009
Background The tuberous sclerosis complex (TSC) is caused by defects in one of two tumor suppressor genes, TSC-1 or TSC-2. TSC-2 gene encodes tuberin, a protein involved in the pathogenesis of kidney tumors, both angiomyolipomas and renal cell carcinomas.

Modulation of 8-Oxoguanine DNA Glycosylase 1 (OGG1) Alleviated Anemia Severity and Excessive Cytokines Release during Plasmodium berghei Malaria in Mice

Iranian Journal of Parasitology
Background: The interplay of OGG1, 8-Oxoguanine, and oxidative stress triggers the exaggerated release of cytokines during malaria, which worsens the outcome of the disease.

Structural and Dynamic Features of the Recognition of 8-oxoguanosine Paired with an 8-oxoG-clamp by Human 8-oxoguanine-DNA Glycosylase

Current Issues in Molecular Biology
8-oxoguanine (oxoG) is formed in DNA by the action of reactive oxygen species. As a highly mutagenic and the most common oxidative DNA lesion, it is an important marker of oxidative stress. Human 8-oxoguanine-DNA glycosylase (OGG1) is responsible for its

Synthetic Routes to N-9 Alkylated 8-Oxoguanines; Weak Inhibitors of the Human DNA Glycosylase OGG1

Molecules, 2015
The human 8-oxoguanine DNA glycosylase OGG1 is involved in base excision repair (BER), one of several DNA repair mechanisms that may counteract the effects of chemo- and radiation therapy for the treatment of cancer. We envisage that potent inhibitors of

Mitochondrial DNA Damage: Role of Ogg1 and Aconitase

, 2011
Mitochondria have a vital role in respiration-coupled energy production, amino acid and fatty acid metabolism, Fe2+/Ca2+ homeostasis and the integration of apoptotic signals that regulate cellular life and death (Babcock et al., 1997; Loeb et al., 2005; Taylor & Turnbull, 2005; Kroemer et al., 2007).

Mechanism of Activation of AMPK and Upregulation of OGG1 by Rapamycin in Cancer Cells

Oncotarget, 2011
AMPK is a physiological cellular energy sensor that is activated by phosphorylation at Thr172 in response to changes in cellular ATP levels. AMPK has been recognized as an important upstream signaling intermediate intimately involved in the regulation of the mTOR pathway [1].
