Comparison of Polynucleotide and Polydeoxyribonucleotide in Dermatology: Molecular Mechanisms and Clinical Perspectives [PDF]

open access: yesPharmaceutics
Polynucleotide (PN) and polydeoxyribonucleotide (PDRN) are DNA-derived biopolymers increasingly recognized for their potential in dermatology. Despite their structural similarities, PN and PDRN exhibit distinct functions due to differences in polymer ...

Defects in Polynucleotide phosphorylase impairs virulence in Escherichia coli O157:H7 [PDF]

open access: goldFrontiers in Microbiology, 2015
Polynucleotide phosphorylase (PNPase) is reported to regulate virulence in Salmonella, Yersinia spp. and Campylobacter jejuni, yet its role in Escherichia coli O157:H7 has not been investigated. To gain insights into its roles in E.

Novel Aspects of Polynucleotide Phosphorylase Function in Streptomyces [PDF]

open access: goldAntibiotics, 2018
Polynucleotide phosphorylase (PNPase) is a 3′–5′-exoribnuclease that is found in most bacteria and in some eukaryotic organelles. The enzyme plays a key role in RNA decay in these systems.

B-cell immunodeficiency associated with polynucleotide kinase 3′-phosphatase (PNKP) deficiency [PDF]

open access: yesJournal of Allergy and Clinical Immunology: Global
Background: DNA repair is crucial for maintaining genomic integrity and plays a significant role in the immune system. Defects in DNA repair pathways are often associated with immunodeficiency, including B-cell defects, which are consistent with the need
