Prokaryotic Argonautes – variations on the RNA interference theme

Microbial Cell, 2014
The discovery of RNA interference (RNAi) has been a major scientific breakthrough. This RNA-guided RNA interference system plays a crucial role in a wide range of regulatory and defense mechanisms in eukaryotes.

Inhibition of dipeptidyl peptidase 7 impairs lysophagy in LLOMe‐treated HepG2 cells

FEBS Letters, EarlyView.
DPP7 inhibition delays ubiquitin‐dependent lysophagy by attenuating ubiquitin accumulation and the recruitment of SQSTM1 and LC3 to damaged lysosomes, resulting in delayed clearance of damaged lysosomes and impaired restoration of lysosomal homeostasis. Created using FigureLabs (Certificate ID: FL‐PUB‐20260922‐Z99XNX).

Conversion of IscB and Cas9 into RNA-guided RNA editors

Cell
RNA-guided RNA editing represents an attractive alternative to DNA editing. However, the prevailing tool, CRISPR-Cas13, has collateral RNA cleavage activity that causes undesirable cytotoxicity in human cells. Here, we report an ultracompact RNA-editing platform engineered from IscB, which has comparable or higher activity than Cas13 but without ...

Generation of Mutant Pigs by Direct Pronuclear Microinjection of CRISPR/Cas9 Plasmid Vectors

Bio-Protocol, 2017
A set of Cas9 and single guide CRISPR RNA expression vectors was constructed. Only a very simple procedure was needed to prepare specific single-guide RNA expression vectors with high target accuracy.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Molecular mechanism of the RNA helicase DHX37 and its activation by UTP14A in ribosome biogenesis [PDF]

, 2019
Eukaryotic ribosome biogenesis is a highly orchestrated process involving numerous assembly factors including ATP-dependent RNA helicases. The DEAH helicase DHX37 (Dhr1 in yeast) is activated by the ribosome biogenesis factor UTP14A to facilitate ...

Systematic identification and characterization of high efficiency Cas9 guide RNAs for therapeutic targeting of ADAR.

PLoS ONE
Therapeutic targeting of the adenosine deaminase ADAR has great potential in cancer and other indications; however, it remains unclear what approach can enable effective and selective therapeutic inhibition.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
