The Double Face of Base Excision Repair: Preventing and Triggering Double‐Strand Breaks
BioEssays, Volume 48, Issue 1, January 2026.Base excision repair is conserved from bacteria to man, robustly eliminating oxidized bases in DNA and reinserting the appropriate nucleotide to restore an intact double helix. Recent results describe conditions and mechanisms that misregulate long‐patch BER to generate double‐strand breaks, triggering chromosome fragmentation and cell death, altering ...

Polynucleotide phosphorylase has an impact on cell biology of Campylobacter jejuni
Frontiers in Cellular and Infection Microbiology, 2012 Polynucleotide phosphorylase, encoded by the pnp gene, is known to degrade mRNA, mediating post-transcriptional regulation and may affect cellular functions. The role of PNPase is pleiotropic.

Linker region is required for efficient nuclear localization of polynucleotide kinase phosphatase.
PLoS ONE, 2020 Polynucleotide kinase phosphatase (PNKP) is a DNA repair factor with dual enzymatic functions, i.e., phosphorylation of 5'-end and dephosphorylation of 3'-end, which are prerequisites for DNA ligation and, thus, is involved in multiple DNA repair ...

The Landscape of Radiofrequency Technology for Skin Rejuvenation
Health Science Reports, Volume 9, Issue 1, January 2026.ABSTRACT Background and Aims Aging skin is characterized by reduced tissue volume, weakened fibrous support, and increased laxity, leading to wrinkles and sagging. While surgical methods are effective, noninvasive techniques like radiofrequency (RF) have gained popularity due to their safety, minimal recovery time, and natural‐looking results.

Journal of Basic Microbiology, Volume 66, Issue 1, January 2026.ABSTRACT Mycobacteriophage Mcgavigan could be a promising candidate for use as a preventative agent against infections with Mycobacterium avium subsp. paratuberculosis. Bioinformatic analysis of the Mcgavigan genome revealed the presence of an operon containing a “Bxb1‐like” repressor.

Polynucleotide Phosphorylase Activity May Be Modulated by Metabolites in Escherichia coli
Journal of Biological Chemistry, 2011 RNA turnover is an essential element of cellular homeostasis and response to environmental change. Whether the ribonucleases that mediate RNA turnover can respond to cellular metabolic status is an unresolved question.

Protein Science, Volume 35, Issue 1, January 2026.Abstract The histamine H3 receptor (H3R) is a class A G protein‐coupled receptor (GPCR) that regulates neurotransmitter release in the central nervous system. Although structures of H3R in both inactive and active states have been elucidated, the functional roles of specific residues remain unclear.
