Engineering IL‐4 resistant proinflammatory human myeloid cells for cancer immunotherapy

open access: yesMolecular Oncology, EarlyView.
We developed a scalable workflow to generate proinflammatory human myeloid cells. CRISPR/Cas9‐edited CD34+ hematopoietic stem and progenitor cells were expanded and differentiated with M‐CSF. Deletion of STAT6 or STAT6/NFKB1 enhanced macrophage proinflammatory gene expression and cytokine secretion in the presence of IL‐4 while maintaining antibody ...

A Tobacco S-like RNase Inhibits Hyphal Elongation of Plant Pathogens

open access: yesMolecular Plant-Microbe Interactions, 2002
Ribonuclease (RNase) NE gene expression is induced in tobacco leaves in response to Phytophthora parasitica. Using antibodies directed against RNase NE, we demonstrate that RNase NE is extracellular at the early steps of the interaction, while the fungal

RNase P RNA‐mediated cleavage [PDF]

open access: yesIUBMB Life, 2009
AbstractMetal(II)‐induced hydrolysis of RNA produce products with 5′‐hydroxyls and 2′;3′‐cyclic phosphates at the ends. Ribozymes are RNA molecules that act as catalysts. Some ribozymes that cleave RNA also generate 5′‐hydroxyls and 2′;3′‐cyclic phosphates whereas others produces 5′‐phosphates and 3′‐hydroxyls at the ends of the cleavage products ...

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

open access: yesMolecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

Bcheck: a wrapper tool for detecting RNase P RNA genes

open access: yesBMC Genomics, 2010
Background Effective bioinformatics solutions are needed to tackle challenges posed by industrial-scale genome annotation. We present Bcheck, a wrapper tool which predicts RNase P RNA genes by combining the speed of pattern matching and sensitivity of ...

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Inhibition of gene expression by RNase P

open access: yesNew Biotechnology, 2010
The ability to interfere with gene expression is of crucial importance to unravel the function of genes and is also a promising therapeutic strategy. Here we discuss methodologies for inhibition of target RNAs based on the cleavage activity of the essential enzyme, Ribonuclease P (RNase P).

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

open access: yesFEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Cryo-electron microscopy structure of an archaeal ribonuclease P holoenzyme

open access: yesNature Communications, 2019
Ribonulease P is a conserved ribozyme present in all kingdoms of life that is involved in the 5′ maturation step of tRNAs. Here the authors determine the structure of an archaeal RNase P holoenzyme that reveals how archaeal RNase P recognizes its tRNA ...

Uniformity amid diversity in RNase P [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
The ribonucleoprotein RNase P, which catalyzes the Mg2+-dependent removal of the 5′ leader sequence in all precursor tRNAs (ptRNAs), is remarkable for the diversity in its subunit composition (Fig. 1 A). Although all RNase P holoenzymes have an essential RNA subunit, the number of protein subunits varies from 1 in Bacteria to at least 4 in Archaea and ...
