MetabolomicsUntargeted Metabolomics Reveals a Lack Of Synergy between Nifurtimox and Eflornithine against Trypanosoma brucei
A non-targeted metabolomics-based approach is presented that enables the study of pathways in response to drug action with the aim of defining the mode of action of trypanocides. Eflornithine, a polyamine pathway inhibitor, and nifurtimox, whose mode of action involves its metabolic activation, are ...

ProteomicsNaa80 acetylates the actin N-terminus impacting the actin cytoskeleton and cell motility
Eukaryotic actins undergo several post-translational modifications during their maturation to enable a fully functional cytoskeletal network. A unique N-terminal processing is conserved in the animal kingdom and includes the removal of the first one or two amino acids as well as N-terminal acetylati...

TranscriptomicsRole of the polypeptide N-acetylgalactosaminyltransferase 3 in ovarian cancer progression: possible implications in abnormal mucin O-glycosylation
Previously, we have identified the polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3) gene as notably hypomethylated in low-malignant potential (LMP) and high-grade (HG) serous epithelial ovarian tumors, compared to normal ovarian tissues. Here we show that GALNT3 is strongly overexpressed in ...

ProteomicsN-terminal acetylome analysis reveals an expanded substrate profile for the NatC N-terminal acetyltransferase complex in yeast
N-terminal acetylation is a conserved protein modification among eukaryotes, and the yeast Saccharomyces cerevisiae is a valuable model system for studying this modification. The enzymes responsible for the bulk of protein N-terminal acetylation in S. cerevisiae are the N-terminal acetyltransferases...

ProteomicsChlamydomonas reinhardtii Mannosidase 1A and Xylosyltransferase1A N-glycosylation LC/MS-MS
We have identified insertional mutants of mannosidase 1A and xylosyltransferase 1A in Chlamydomonas reinhardtii. Mass spectrometric analyses of intact N-glycopeptides revealed that disruption of the genes altered the N-glycan composition of the alga (in single as well as double mutant). In contrast ...

ProteomicsHuman serum N-linked intact glycopeptides LC-MS/MS
Large-scale identification of N-linked intact glycopeptides by liquid chromatography coupled tandem mass spectrometry (LC-MS/MS) in human serum is challenging due to the wide dynamic range of serum protein abundances, the lack of a complete serum N-Glycan database and the existence of non-specifical...

GenomicsDnmt2-dependent methylomes lack biologically relevant DNA methylation patterns
Several organisms belonging to diverse animal groups have retained Dnmt2 as their only bona fide DNA methyltransferase gene. However, recent studies have shown that Dnmt2 functions as a tRNA methyltransferase, which prompted us to analyze the methylomes of Dnmt2-only organisms at single-base resolut...

ProteomicsAffinity peptide ligands: New tools for chasing non-canonical N-phosphoproteome
Protein N-phosphorylation enrichment is faced with great difficulties due to the intrinsic instability of the N-P bond, which has seriously hindered its biological function unraveling. Current methods for N-phosphopeptides enrichment are challenging to fulfil high selectivity for all types of N-phos...

ProteomicsQuantitative N-glycoproteomic analysis reveals glycosylation signatures of plasma immunoglobulin G in systemic sclerosis
Systemic sclerosis (SSc) is a perplexing autoimmune disorder, characterized by mysterious causes, high mortality rates, and a lack of effective treatments. The role of abnormal glycosylation in the onset of autoimmune diseases has been recognized for some time. Nonetheless, the intricate details of ...
