Chemical Exposures, DNA Methylation and Whole Blood DNA Damage in Pet Golden Retrievers

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Canine multicentric lymphoma (CL) is a common and typically fatal cancer among dogs. Although certain breeds have a higher incidence of CL, its environmental risk factors remain uncertain. Exposures to herbicides and volatile organic compounds (VOCs) associate with non‐Hodgkin lymphoma in people.

Cucumber green mottle mosaic virus: A persistent seed‐borne threat to cucurbits

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Cucumber green mottle mosaic virus (CGMMV) is a highly stable, seed‐borne tobamovirus that threatens global cucurbit production. Its efficient mechanical and seed transmission, long‐term environmental persistence, and the spread of Clade II CGMMV isolates drive its rapid dissemination and cause severe yield losses.

Approaches to Detection of Distantly Related Proteins by Database Searches

BioTechniques, 1996
The searching of protein databases as a method of identifying newly sequenced genes is commonplace in molecular biology laboratories. However, it is a procedure that is not usually formally taught to students, and method cookbooks discuss it only briefly.

A stage‐dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean

Plant, Cell &Environment, Volume 49, Issue 7, Page 3500-3517, July 2026.
Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

The Influence of (5′R)- and (5′S)-5′,8-Cyclo-2′-Deoxyadenosine on UDG and hAPE1 Activity. Tandem Lesions are the Base Excision Repair System’s Nightmare

Cells, 2019
DNA lesions are formed continuously in each living cell as a result of environmental factors, ionisation radiation, metabolic processes, etc. Most lesions are removed from the genome by the base excision repair system (BER).

DNA Hypomethylation Is One of the Epigenetic Mechanisms Involved in Salt‐Stress Priming in Soybean Seedlings

Plant, Cell &Environment, Volume 49, Issue 7, Page 3764-3776, July 2026.
ABSTRACT Salt‐stress priming enhances the tolerance of plants against subsequent exposure to a similar stress. Priming‐induced transcriptomic reprogramming is mediated by multiple epigenetic mechanisms, the best known of which is histone modifications. However, not much is known about other epigenetic responses.

Hippocampal Adult Neurogenesis Is Maintained by Neil3-Dependent Repair of Oxidative DNA Lesions in Neural Progenitor Cells

Cell Reports, 2012
Accumulation of oxidative DNA damage has been proposed as a potential cause of age-related cognitive decline. The major pathway for removal of oxidative DNA base lesions is base excision repair, which is initiated by DNA glycosylases.

Structural basis for human OGG1 processing 8-oxodGuo within nucleosome core particles

Nature Communications
Base excision repair (BER) is initialized by DNA glycosylases, which recognize and flip damaged bases out of the DNA duplex into the enzymes active site, followed by cleavage of the glycosidic bond.

A Central Somatic Transmission Mediates Proprioceptive Facilitation of Muscle Pain

Advanced Science, Volume 13, Issue 34, 19 June 2026.
Zhang et al. uncover a novel central mechanism for persistent muscle pain, in which TRPA1 sensitization in MeV proprioceptive neurons enhances somatic secretion. This, in turn, disinhibits descending pain control from neighboring noradrenergic locus coeruleus neurons via local GABAergic circuits, thereby promoting inflammatory muscle pain.

Electroacupuncture Ameliorates Cognitive Impairment in Vascular Dementia Rats: Potential Involvement of the Astrocyte–Synapse Axis

Brain and Behavior, Volume 16, Issue 6, June 2026.
Electroacupuncture significantly ameliorates cognitive impairment and synaptic damage in vascular dementia rats, showing specific advantages over nimodipine. These neuroprotective effects are closely associated with modulating the astrocyte–synapse axis to suppress neuroinflammation and enhance neurotrophic support.
