An Investigation into the Interaction of Various Salt Ions with DNA Topoisomerase IA during the Relaxation of Negatively-Supercoiled DNA. [PDF]

open access: yes, 2007
Topoisomerases are enzymes that change the topological state of DNA by catalyzing the cleavage, subsequent strand passage and religation of either one or both strands of DNA during DNA replication and transcription.

Polo‐like kinases and UV‐induced skin carcinogenesis: What we know and what's next

open access: yesPhotochemistry and Photobiology, EarlyView.
The polo‐like kinase (PLK) family plays distinct and critical roles in the regulation of cell cycle progression, and its dysregulation has been implicated in various cancers. Ultraviolet (UV) radiation is a well‐established environmental factor in the development of skin cancer.

Predicting Knot or Catenane Type of Site-Specific Recombination Products

open access: yes, 2007
Site-specific recombination on supercoiled circular DNA yields a variety of knotted or catenated products. We develop a model of this process, and give extensive experimental evidence that the assumptions of our model are reasonable. We then characterize

Antibiotic‐mediated immune modulation in periodontitis

open access: yesPeriodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Clinical validation of a DNA methylation biomarker associated with overall survival of relapsed ovarian cancer patients

open access: yesInternational Journal of Cancer, Volume 158, Issue 7, Page 1821-1835, 1 April 2026.
What's new? Most patients with ovarian cancer (OC) relapse after first‐line chemotherapy, and prognosis with second‐line treatment depends largely on the platinum‐free interval. However, reliable biomarkers to predict response to second‐line therapy remain lacking.

ATP independent type IB topoisomerase of Leishmania donovani is stimulated by ATP: an insight into the functional mechanism [PDF]

open access: yes, 2017
Most type IB topoisomerases do not require ATP and Mg2+ for activity. However, as shown previously for vaccinia topoisomerase I, we demonstrate that ATP stimulates the relaxation activity of the unusual heterodimeric type IB topoisomerase from Leishmania

Is Micronucleus Assay a Suitable Biomarker for Evaluating the Cancer Risk in Professionals Exposed to Antineoplastic Drugs? A Systematic Review

open access: yesJournal of Applied Toxicology, Volume 46, Issue 3, Page 733-753, March 2026.
ABSTRACT The widespread use of antineoplastic drugs in cancer treatment has led to significant concerns regarding the potential health risks posed to healthcare professionals involved in the preparation, administration, and handling of these chemical compounds, including genotoxicity.

Targeting Tumor Dormancy and Recurrence: Molecular Mechanisms and Peptide Therapeutic Delivery

open access: yesMedComm – Oncology, Volume 5, Issue 1, March 2026.
This review summarizes the molecular mechanisms that regulate tumor dormancy and its role in cancer recurrence, with emphasis on immune evasion, extracellular matrix remodeling, metabolic regulation and angiogenic switching. It further discusses emerging peptide–based therapeutic strategies aimed at detecting, modulating, and eliminating dormant tumor ...

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.
