ProteomicsMass spectrometry-based top-down proteomics in nanomedicine: proteoform-specific measurement of protein corona
Conventional mass spectrometry (MS)-based bottom-up proteomics (BUP) analysis of protein corona [i.e., an evolving layer of biomolecules, mostly proteins, formed on the surface of nanoparticles (NPs) during their interactions with biomolecular fluids] enabled nanomedicine community to partly identif...

ProteomicsMass Spectrometry-Based Top-Down Proteomics for Proteoform Profiling of Protein Corona
The protein corona, a layer of biomolecules—primarily proteins—that adsorb to nanoparticle (NP) surfaces in biological fluids, critically affects NP safety and their therapeutic and diagnostic functions. Additionally, the protein corona effectively reduces proteome complexity and the dynamic range o...

ProteomicsTop-down Nanoparticle-corona by cIEF-MS/MS
In the rapidly evolving field of nanomedicine, understanding the interactions between nanoparticles and biological systems is crucial. A pivotal aspect of these interactions is the formation of a protein corona when nanoparticles are exposed to biological fluids, which significantly influences their...

ProteomicsFinding the optimal degassing condition for linear polyacrylamide coated capillaries used in capillary zone electrophoresis-mass spectrometry-based top-down proteomics
LPA-coated capillaries are widely used; however, the quality of the coating—which directly affects separation performance and analyte identification—can vary significantly depending on the individual performing the procedure. A critical factor in achieving consistent coating quality is the degassing...

ProteomicsHIRA and dPCIF1 coordinately establish totipotent chromatin and control orderly ZGA in Drosophila embryos
In order to understand the molecular mechanism underlying the action of dPCIF1 in early embryos, we carried out co-immunoprecipitation (co-IP) assays followed by mass spectroscopic analysis using dPCIF1GFP-KI early embryos (0.5–1.5 hours). In this assay, we identified a large number of dPCIF1-intera...

ProteomicsThe TET-Sall4-BMP regulatory axis controls craniofacial cartilage development
Craniofacial microsomia (CFM) is a congenital defect that usually results from aberrant development of embryonic pharyngeal arches. However, the molecular basis of CFM pathogenesis is largely unknown. Here, we employ the zebrafish model to investigate mechanisms of CFM pathogenesis. In early embryos...
