Looping forward: exploring R‐loop processing and therapeutic potential

FEBS Letters, Volume 599, Issue 2, Page 244-266, January 2025.
R‐loops function as both regulators of gene expression, DNA repair, telomere maintenance or chromosome segregation, and as drivers of genome instability. This dual nature of these structures is coordinated by RNA/DNA/chromatin processing factors that safeguard the genome from detrimental R‐loop‐instigated DNA damage or cellular dysfunction ...

Human mitochondrial RNA decay mediated by PNPase-hSuv3 complex takes place in distinct foci. [PDF]

, 2013
RNA decay is usually mediated by protein complexes and can occur in specific foci such as P-bodies in the cytoplasm of eukaryotes. In human mitochondria nothing is known about the spatial organization of the RNA decay machinery, and the ribonuclease ...

The RNA processing enzyme polynucleotide phosphorylase negatively controls biofilm formation by repressing poly-N-acetylglucosamine (PNAG) production in Escherichia coli C

BMC Microbiology, 2012
Background Transition from planktonic cells to biofilm is mediated by production of adhesion factors, such as extracellular polysaccharides (EPS), and modulated by complex regulatory networks that, in addition to controlling production of adhesion ...

Inductively Coupled Plasma Mass Spectrometry Performance for the Measurement of Key Serum Minerals: A Comparative Study With Standard Quantification Methods

Journal of Clinical Laboratory Analysis, Volume 39, Issue 2, January 2025.
Analysis of real‐world cross‐sectional study data revealed relative errors between the standard method and ICP‐MS for the different minerals tested. Additionally, several outliers were observed exclusively in the ICP‐MS results, likely due to hemolysis or other unidentified factors.

The small RNA SraG participates in PNPase homeostasis

RNA: A publication of the RNA Society, 2016
The rpsO-pnp operon encodes ribosomal protein S15 and polynucleotide phosphorylase, a major 3′–5′ exoribonuclease involved in mRNA decay in Escherichia coli. The gene for the SraG small RNA is located between the coding regions of the rpsO and pnp genes,

Novel resources to investigate leaf plasmodesmata formation in C3 and C4 monocots

The Plant Journal, Volume 120, Issue 5, Page 2207-2225, December 2024.
SUMMARY Plasmodesmata (PD) are nanochannels that facilitate cell‐to‐cell transport in plants. More productive and photosynthetically efficient C4 plants form more PD at the mesophyll (M)‐bundle sheath (BS) interface in their leaves than their less efficient C3 relatives.

Histochemical demonstration of purine nucleoside phosphorylase (PNPase) in microglial and astroglial cells of adult rat brain.

, 1990
The histochemical localization of enzymes associated with purine nucleoside metabolism indicates that glial cells might participate in the regulation of these compounds in the central nervous system.

Structural insights into the dimeric human PNPase revealing why the disease-linked mutants exhibit lower RNA import and degradation activities

Acta Crystallographica Section A: Foundations and Advances, 2018
Polynucleotide phosphorylase (PNPase) is an evolutionary conserved 3'-to-5' exoribonuclease that functions differently among species, ranging from RNA turnover in bacteria to RNA transport in mammals.
