Human APOBEC3G suppresses homologous recombination and LIG4‐independent end joining in DNA double‐strand break repair

open access: yesThe FEBS Journal, EarlyView.
Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

Identification of Genetic Loci Conveying Resistance to Fusarium oxysporum f. sp. ciceris Race 0 in Chickpea

open access: yesPlant Breeding, EarlyView.
ABSTRACT Chickpea (Cicer arietinum L.) is a legume that is widely consumed around the world due to its nutritional content. Fusarium oxysporum f. sp. ciceris is a serious, destructive pathogen that causes fusarium wilt disease and affects chickpea production.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

Differential Regulation of Methylation-Regulating Enzymes by Senescent Stromal Cells Drives Colorectal Cancer Cell Response to DNA-Demethylating Epi-Drugs

open access: yesStem Cells International, 2018
The advanced-stage colon cancer spreads from primary tumor site to distant organs where the colon-unassociated stromal population provides a favorable niche for the growth of tumor cells.

Myelodysplastic Syndromes: 2026 Update on Diagnosis, Risk‐Stratification and Management

open access: yesAmerican Journal of Hematology, Volume 101, Issue 9, Page 2393-2411, September 2026.
ABSTRACT Disease Overview The myelodysplastic syndromes (MDS) are a heterogeneous group of myeloid disorders characterized by peripheral blood cytopenias and increased risk of transformation to acute myelogenous leukemia (AML). MDS occurs more frequently in older males and in individuals with prior exposure to cytotoxic therapy.

Metabolic constraint of human telomere length by nucleotide salvage efficiency

open access: yesNature Communications
Human telomere length is tightly regulated and associated with diseases at either extreme, but how these bounds are established remains incompletely understood.

The relation between deoxycytidine kinase activity and the radiosensitising effect of gemcitabine in eight different human tumour cell lines

open access: yesBMC Cancer, 2006
Background Gemcitabine (dFdC) is an active antitumour agent with radiosensitising properties, shown both in preclinical and clinical studies. In the present study, the relation between deoxycytidine kinase (dCK) activity and the radiosensitising effect ...

FUCA2 Sustains AKT Signaling and Suppresses Senescence by Antagonizing FUT3‐Mediated ErbB3 Fucosylation in Lung Adenocarcinoma

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
ABSTRACT While targeted therapies have improved outcomes in lung adenocarcinoma (LUAD), many patients still lack targetable mutations. Here, we identified alpha‐L‐fucosidase 2 (FUCA2) as a crucial driver of LUAD by preventing cellular senescence. Mechanistically, through the restriction of fucosyltransferase 3 (FUT3)‐mediated α‐1,3‐fucosylation of ...

A Modular Nucleoside Kinase Cascade for the Synthesis of Ribonucleoside Triphosphates

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 8, Page 2180-2191, August 2026.
Damm et al. report standardized enzymatic cascades for production of all canonical nucleoside triphosphates from the corresponding nucleosides, using kinase‐catalyzed phosphorylation from acetyl phosphate. Reactions afforded ∼ 100 mM product in near‐quantitative conversion.

Epigenetic Mechanisms Underlying Cognitive Dysfunction in Parkinson's Disease: Current Evidence and Future Prospects

open access: yesBrain and Behavior, Volume 16, Issue 8, August 2026.
Epigenetic mechanismsincluding DNA methylation, histone modifications, and microRNA (miRNA) regulationmodulate gene expression without altering the DNA sequence and are increasingly implicated in the cognitive impairment associated with Parkinson's disease (PD). Environmental and molecular factors influence these epigenetic pathways, leading to altered
