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...

TranscriptomicsInfluence of RNA Labeling on Expression Profiling of MicroRNAs
Several technical parameters are now being optimized for microRNA expression profiling experiments, but the finite amount of total RNA available continues to bottleneck clinical investigations. We used microarrays to determine the influence of the labeling reagent on total RNA requirements and data ...

ProteomicsBiotin proximity tagging favors unfolded proteins and enables the study of intrinsically disordered regions
Intrinsically Disordered Regions (IDRs) are enriched in disease-linked proteins known to have multiple post-translational modifications, but there is limited in vivo information about how locally unfolded protein regions contribute to biological functions. We reasoned that IDRs should be more access...

ProteomicsIntegrated Dissection of Cysteine Oxidative Modification Proteome During Cardiac Hypertrophy
Cysteine oxidative modification of cellular proteins is crucial for many aspects of cardiac hypertrophy development. However, integrated dissection of multiple types of cysteine oxidation proteome in cardiac hypertrophy is currently missing. Here we developed a novel discovery platform encompassing ...

ProteomicsOXIPEP: mass spectrometry strategy to characterize protein carbonylation.
Here we describe a peptide-centric approach (OXIPEP), where carbonylated residues within proteins are derivatized with biotin-hydrazide, enriched and identified by mass spectrometry. The strength of the method lies in an improved protocol for elution of biotinylated peptides from monomeric avidin r...

ProteomicsBiotin-Labelled Clavulanic Acid to Identify Proteins Target for Haptenation in Serum: Implications in Allergy Studies
Clavulanic acid (CLV) and amoxicillin, frequently administered in combination, can be independently involved in allergic reactions. Protein haptenation with β-lactams is considered necessary to activate the immune system. The aim of this study was to assess the suitability of biotinylated analogues ...

ProteomicsMudPIT analyses of the human proteins biotinylated by proximity to exogenously expressed biotin ligase (BioID)
To identify non-specific biotinylation events, HEK293 cells transfected with a plasmid carrying only the biotin ligase moiety were used as negative controls to BioID experiments. Cells were lysed in the presence of detergents. After purification of biotinylated proteins on streptavidin-conjugated be...

ProteomicsQuantification of sulfenic acid modification in an atherosclerosis
Physiological stimuli such as thrombin, or pathological stimuli such as lysophosphatidic acid (LPA), activate platelets. The activated platelets bind to monocytes through P-selectin-PSGL-1 interactions, but also release the contents of their granules, commonly called “platelet releasate”. It is know...
