From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Impact of Helicobacter pylori Infection and Its Major Virulence Factor CagA on DNA Damage Repair

Microorganisms, 2020
Helicobacter pylori infection induces a plethora of DNA damages. Gastric epithelial cells, in order to maintain genomic integrity, require an integrous DNA damage repair (DDR) machinery, which, however, is reported to be modulated by the infection.

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...

The E3 Ubiquitin Ligase NEDD4L Targets OGG1 for Ubiquitylation and Modulates the Cellular DNA Damage Response

Frontiers in Cell and Developmental Biology, 2020
8-Oxoguanine DNA glycosylase (OGG1) is the major cellular enzyme required for the excision of 8-oxoguanine DNA base lesions in DNA through the base excision repair (BER) pathway, and therefore plays a major role in suppressing mutagenesis and in ...

Optimized TadA‐derived base editors efficiently manipulate mRNA splicing by A‐to‐G and C‐to‐K editing in potato

Journal of Integrative Plant Biology, EarlyView.
Two optimized TadA‐derived base editors efficiently generate diverse splicing variants by targeting specific splice sites in potato. ABSTRACT Pre‐messenger RNA (pre‐mRNA) splicing is a critical mechanism for post‐transcriptional regulation in plants. Through alternative splicing, plants produce diverse transcriptomes and proteomes that finely regulate ...

Research progress on the role of the NEIL family in cancer

Frontiers in Cell and Developmental Biology
Cancer is the primary cause of death worldwide. Cancer occurrence and progression are closely associated with DNA damage repair. DNA glycosylase were the first enzymes to initiate base excision repair, and the Nei-like DNA glycosylase (NEIL) family has ...

Resolution and Quantitation of Ribonucleosides and Deoxyribonucleosides in Digested Genomic DNA by UHPLC–MS/MS

Biomedical Chromatography, Volume 40, Issue 10, October 2026.
ABSTRACT Deoxyuridine (dUrd) is often misincorporated into genomic DNA in cancer patients receiving antimetabolite chemotherapy. This activates base excision repair and recruits ataxia telangiectasia‐mutated and Rad3‐related (ATR), which coordinates DNA repair with nucleotide metabolism by facilitating ribonucleotide reductase (RNR) activity ...
