Memory efficient folding algorithms for circular RNA secondary structures [PDF]

, 2018
Background: A small class of RNA molecules, in particular the tiny genomes of viroids, are circular. Yet most structure prediction algorithms handle only linear RNAs. The most straightforward approach is to compute circular structures from ‘internal’ and

The impact of leukocyte‐associated RNA retention on platelet RNA‐based cancer detection

Molecular Oncology, EarlyView.
Platelets carry RNA signals that may help detect cancer, but platelet samples can also retain RNA from white blood cells. We found that this retained white blood cell signal did not significantly affect machine learning cancer classification, suggesting that the cancer‐related RNA signal in platelets is largely independent of leukocyte‐associated RNA ...

RNA methylation by NSUN4 marks mitochondrial double-stranded RNAs for degradation

, 2022
Human mitochondria have a compact circular genome that encodes 13 protein-coding genes as well as mitochondrial rRNAs and tRNAs. While most protein-coding genes are located in the heavy strand of the genome, the mitochondrial transcription occurs ...

Optimal design of synthetic circular RNAs

Experimental and Molecular Medicine
Circular RNAs are an unusual class of single-stranded RNAs whose ends are covalently linked via back-splicing. Due to their versatility, the need to express circular RNAs in vivo and in vitro has increased.

Circular transcriptome sequencing of the middle silk gland and posterior silk gland in the Bombyx mori

Data in Brief, 2017
Circular transcriptome sequencing of the middle silk gland (MSG) and posterior silk gland (PSG) in the Bombyx mori are presented. The middle silk gland and posterior silk gland were collected from the third day of fifth-instar B.mori larvae. The circular

Overcoming platinum resistance by the disulfiram metabolite CuET in novel preclinical models of human carcinomas

Molecular Oncology, EarlyView.
Cisplatin‐resistant cancer cells survive DNA‐damaging platinum‐based treatment yet remain sensitive to CuET‐induced proteotoxic stress. The distinct mechanism of action allows CuET to overcome and eliminate cisplatin‐resistant tumour cells, unless highly expressed metallothioneins (MTs) interfere with CuET, thereby highlighting MT levels as candidate ...

Circular RNAs

EXCLI Journal : Experimental and Clinical Sciences, 2023
Circular RNAs (CircRNAs) are a class of regulatory RNA transcripts, which are ubiquitously expressed in eukaryotes. CircRNA dysregulation has been shown to disrupt the interaction of the Wnt/β-catenin pathway, which regulates several biological processes involved in tumorigenesis, thereby contributing to the development and progression of cancer ...

Influence of RNA circularity on Target RNA-Directed MicroRNA Degradation. [PDF]

A subset of circular RNAs (circRNAs) and linear RNAs have been proposed to 'sponge' or block microRNA activity. Additionally, certain RNAs induce microRNA destruction through the process of Target RNA-Directed MicroRNA Degradation (TDMD), but whether ...

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

Molecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.
