MetabolomicsN6-methyladenosine modification is not a general trait of positive-sense RNA viral genomes

Despite the nuclear localization of the m6A machinery, the genomes of multiple exclusively-cytoplasmic RNA viruses, such as chikungunya (CHIKV) and dengue (DENV), are reported to be extensively m6A-modified. However, these findings are mostly based on m6A-seq, an antibody-dependent technique with...

MetabolomicsRNA modification dynamics during Enterococcus faecalis OG1RF growth
Quantitative analysis of relative levels of RNA modifications in small (primarily tRNA) and large (primarily 16S/23S rRNA) RNAs isolated from Enterococcus faecalis OG1RF across a growth time course in BHI media.

MetabolomicsB-cell Translocation Gene 2 Inhibits UFMylation Modification of FMO1 thus Restricting Taurine Synthesis and Exacerbating Ferroptosis in Hepatic Ischemia-Reperfusion Injury

Hepatic ischemia-reperfusion (I/R) injury is a common complication occurs during liver transplantation. However, the mechanisms underlying hepatic I/R injury have not been fully elucidated. B-cell translocation gene 2 (Btg2) has been implicated in the development of various diseases. However, its...

GenomicsThe alteration of 5-hydroxymethylcytosine modification contributes to ischemic brain injury [5hmC-seq]
Epigenetic modifications, such as cytosine methylation and histone modification, have been shown involved in the pathology of ischemic brain injury. Recent works have implicated 5-hydroxymethylcytosine (5hmC), a DNA base derived from 5-methylcytosine (5mC) through the oxidation by Ten-Eleven Translo...

GenomicsSelective chemical labeling reveals intragenic enrichment of 5-hydroxymethylcytosine in mouse cerebellum
5-Methylcytosine (5-mC) is an important DNA modification found in eukaryotes that impacts gene regulation and disease pathogenesis. Recently, 5-hydroxymethylcytosine (5-hmC), another form of DNA modification, has been identified in substantial amounts in certain mammalian cell types; however, its ro...

TranscriptomicsChemical modifications mark alternatively spliced and actively degrading messenger RNAs in Arabidopsis and humans
Post-transcriptional chemical modification of RNA bases is a widespread and physiologically relevant regulator of RNA maturation, stability, and function. While modifications are best characterized in short, noncoding RNAs such as transfer RNAs (tRNAs), growing evidence indicates that messenger RNAs...

ProteomicsA Bioorthogonal Chemical Reporter for the Detection and Identification of Protein Lactylation
L-Lactylation is a recently discovered post-translational modification occurring on histone lysine residues to regulate gene expression. However, the substrate scope of lactylation, especially that in non-histone proteins, remains unknown, largely due to the limitations of current methods for analyz...
