Identification of Polynucleotide Phosphorylase (PNPase) in Escherichia coli Involved in Persister Formation

bioRxiv, 2018
Despite the identification of many genes and pathways involved in the persistence phenomenon of bacteria, the mechanisms of persistence are not well understood.

Composition and conservation of the mRNA-degrading machinery in bacteria [PDF]

, 2011
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts.

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.

Impact of PNPase on the transcriptome of Rhodobacter sphaeroides and its cooperation with RNase III and RNase E

BMC Genomics, 2021
Background The polynucleotide phosphorylase (PNPase) is conserved among both Gram-positive and Gram-negative bacteria. As a core part of the Escherichia coli degradosome, PNPase is involved in maintaining proper RNA levels within the bacterial cell.

The structure of Rph, an exoribonuclease from Bacillus anthracis, at 1.7 angstrom resolution [PDF]

, 2008
Maturation of tRNA precursors into functional tRNA molecules requires trimming of the primary transcript at both the 5' and 3' ends. Cleavage of nucleotides from the 3' stem of tRNA precursors, releasing nucleotide diphosphates, is accomplished in ...

Cardiovascular Disease Management and Prevention in Saudi Arabia: Strategies, Risk Factors, and Targeted Interventions

International Journal of Clinical Practice, Volume 2025, Issue 1, 2025.
Cardiovascular diseases (CVDs) remain the main cause of mortality and are generally among the leading causes of morbidity worldwide, thus placing an immense burden on health care. They include coronary artery disease, heart failure, hypertensive heart disease, and stroke. Among these, common risk factors include hypertension, high cholesterol, diabetes,

“Purification and Characterization of Deinococcus radiodurans Polynucleotide Phosphorylase a phosphate stimulated Mn2+‐dependent nuclease”

The FASEB Journal, 2017
DNA double strand breaks, if unrepaired, pose a threat to the cell because they can cause a wide variety of genetic alteration and apoptosis. Therefore, DNA double‐strand break repair pathways are critical for the survival of all organisms.

Genome-Wide Study of mRNA Degradation and Transcript Elongation in Escherichia coli [PDF]

, 2015
An essential part of gene expression is the coordination of RNA synthesis and degradation, which occurs in the same cellular compartment in bacteria.

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.
