Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Advances in RNA cytosine-5 methylation: detection, regulatory mechanisms, biological functions and links to cancer

open access: yesBiomarker Research, 2020
As an important posttranscriptional modification of RNA, 5-methylcytosine (m5C) has attracted increasing interest recently, with accumulating evidence suggesting the involvement of RNA m5C modification in multiple cellular processes as well as ...

RNAME: A comprehensive database of RNA modification enzymes

open access: yesComputational and Structural Biotechnology Journal, 2022
The dynamic RNA modifications were orchestrated by a series of enzymes, namely “writer”, “reader” and “eraser”, which can install, recognize and remove the modifications, respectively.

RNA modification in Cajal bodies [PDF]

open access: yesRNA Biology, 2016
Aside from nucleoli, Cajal bodies (CBs) are the best-characterized organelles of mammalian cell nuclei. Like nucleoli, CBs concentrate ribonucleoproteins (RNPs), in particular, spliceosomal small nuclear RNPs (snRNPs) and small nucleolar RNPs (snoRNPs).

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

The landscape of m1A modification and its posttranscriptional regulatory functions in primary neurons

open access: yeseLife, 2023
Cerebral ischaemia‒reperfusion injury (IRI), during which neurons undergo oxygen-glucose deprivation/reoxygenation (OGD/R), is a notable pathological process in many neurological diseases.

Suppression of Argonaute 2 Transcript Levels in Du182A Cells [PDF]

open access: yes, 2018
RNA interference (RNAi) uses double-stranded RNA (dsRNA) molecules to degrade and suppress the transcript level of a complementary mRNA target1.

Cfp1 is required for gene expression dependent H3K4me3 and H3K9 acetylation in embryonic stem cells [PDF]

open access: yes, 2014
BackgroundTrimethylation of histone H3 lysine 4 (H3K4me3) accumulates at promoters in a gene activity dependent manner. The Set1 complex is responsible for most H3K4me3 in somatic cells and contains the conserved subunit Cfp1, which is implicated in ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...
