Supernatants derived from chemotherapy-treated cancer cell lines can modify angiogenesis [PDF]

, 2012
BACKGROUND: There is evidence that tumours produce substances such as cytokines and microvesicular bodies bearing bioactive molecules, which support the carcinogenic process.

Genome wide association studies for acid phosphatase activity at varying phosphorous levels in Brassica juncea L

Frontiers in Plant Science, 2022
Acid phosphatases (Apases) are an important group of enzymes that hydrolyze soil and plant phosphoesters and anhydrides to release Pi (inorganic phosphate) for plant acquisition. Their activity is strongly correlated to the phosphorus use efficiency (PUE)

A PNPase dependent CRISPR System in Listeria. [PDF]

PLoS Genetics, 2014
The human bacterial pathogen Listeria monocytogenes is emerging as a model organism to study RNA-mediated regulation in pathogenic bacteria. A class of non-coding RNAs called CRISPRs (clustered regularly interspaced short palindromic repeats) has been ...

Analysis of mRNA Decay Intermediates in Bacillus subtilis 3′ Exoribonuclease and RNA Helicase Mutant Strains

mBio, 2022
The Bacillus subtilis genome encodes four 3′ exoribonucleases: polynucleotide phosphorylase (PNPase), RNase R, RNase PH, and YhaM. Previous work showed that PNPase, encoded by the pnpA gene, is the major 3′ exonuclease involved in mRNA turnover; in a ...

The ribonuclease PNPase is a key regulator of biofilm formation in Listeria monocytogenes and affects invasion of host cells

npj Biofilms and Microbiomes, 2023
Biofilms provide an environment that protects microorganisms from external stresses such as nutrient deprivation, antibiotic treatments, and immune defences, thereby creating favorable conditions for bacterial survival and pathogenesis. Here we show that

Insights into Xanthomonas axonopodis pv. citri biofilm through proteomics [PDF]

, 2013
Background: Xanthomonas axonopodis pv. citri (X. a. pv. citri) causes citrus canker that can result in defoliation and premature fruit drop with significant production losses worldwide. Biofilm formation is an important process in bacterial pathogens and

Defects of mitochondrial RNA turnover lead to the accumulation of double-stranded RNA in vivo.

PLoS Genetics, 2019
The RNA helicase SUV3 and the polynucleotide phosphorylase PNPase are involved in the degradation of mitochondrial mRNAs but their roles in vivo are not fully understood.
