Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Dynamic landscape of m6A modifications and related post-transcriptional events in muscle-invasive bladder cancer

Journal of Translational Medicine
Background Muscle-invasive bladder carcinoma (MIBC) is a serious and more advanced stage of bladder carcinoma. N6-Methyladenosine (m6A) is a dynamic and reversible modifications that primarily affects RNA stability and alternative splicing.

Using the cre-lox recombination system to assess functional impairment caused by amino acid substitutions in yeast proteins

Biological Procedures Online, 2004
A method was developed to assess the functional significance of a sequence motif in yeast Upf3p, a protein required for nonsense-mediated mRNA decay (NMD).

A Genome-Scale Atlas Reveals Complex Interplay of Transcription and Translation in an Archaeon

mSystems, 2023
The scale of post-transcriptional regulation and the implications of its interplay with other forms of regulation in environmental acclimation are underexplored for organisms of the domain Archaea.

Computational analysis of next generation sequencing data : from transcription start sites in bacteria to human non-coding RNAS [PDF]

, 2014
The advent of next generation sequencing (NGS) technologies has revolutionized the field of molecular biology by providing a wealth of sequence data. “Transcriptomics”, which aims to identify and annotate the complete set of RNA molecules transcribed ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Characterizing transcripts of HIV-1 different substrains using direct RNA sequencing

Heliyon
Post-transcriptional processing and modification of viral RNA, including alternative splicing, polyadenylation, and methylation, play crucial roles in regulating viral gene expression, enhancing genomic stability, and increasing replication efficiency ...

RNA interference, growth and differentiation appear normal in African trypanosomes lacking Tudor staphylococcal nuclease. [PDF]

, 2010
Ribonucleases play important roles in the RNA interference (RNAi) pathway. The Dicer endonuclease converts double-stranded (ds)RNA into small interfering (si)RNA and the Slicer endonuclease, as a component of the RNA induced silencing complex (RISC ...

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.

Saccharomyces cerevisiae U14 small nuclear RNA has little secondary structure and appears to be produced by post-transcriptional processing.

Journal of Biological Chemistry, 1994
Yeast U14 small nuclear (sn) RNA is required for normal processing of rRNA. The sequence and folding properties of U14 were analyzed in the present study, with the aim of defining the structures of natural U14 subspecies and characterizing the folding properties of free U14 RNA.
