Topic: Role of Mass Spectrometry in Chemical Analysis of Medical Device Extractables

Date: December 16, 2024

Time: 6:15 pm Dinner, 7:15 pm Presentation

Location: Shimadzu Scientific Instrument, Inc. Training Center 7100 Riverwood Drive, Columbia, MD 21046 (Directions)

Dinner: Please RSVP to Dingyin Tao (owendtao@gmail.com) by Friday, December 13 if you will be attending the dinner.

Abstract: Chemical analysis of medical device extracts has two main purposes: identification of unknown medical device constituents and quantification of known or unknown extractables. Mass spectrometry is an essential part of chemical analysis of medical device extractables. Identification of the extractables is an ongoing challenge with limited options. Quantification is also an important task in this field as the toxicologists, who need this chemical analysis data, make important decisions based on the both the identity and the reported quantities of the extractables. This presentation will attempt to offer a summary of the current status, ongoing research and challenges related to mass spectrometry in this field, and also lists future directions

Location: Shimadzu Scientific Instrument, Inc. Training Center 7100 Riverwood Drive, Columbia, MD 21046 (Directions)

Abstract: Drug overdoses remain near all-time highs, driven by the continued prevalence of synthetic opioids coupled with a constantly changing drug supply. Keeping pace with the drug supply makeup using traditional approaches (i.e., forensic laboratories or toxicology testing) is difficult due to backlogs and lagging spectral libraries. To address these challenges, NIST has worked to establish the Rapid Drug Analysis and Research (RaDAR) program which provides public health and law enforcement entities across the country access to rapid (24 hour) turnaround, comprehensive drug testing using drug paraphernalia residue and ambient ionization mass spectrometry (AI-MS). In this presentation I will discuss our efforts to develop AI-MS methods, libraries, and algorithms that have enabled this measurement capability, what data we are generating and how it is being used, and outstanding data analytic challenges we face. In addition, I will touch on our ongoing research efforts to develop rapid quantitation methods for drug samples as well as a new initiative to bring high-resolution AI-MS to the field through a mobile laboratory platform.

Abstract: Since the completion of the Human Genome Project, much has been made of the need to bridge the gap from genes and traits. As a key nexus for the many interacting ‘-omes’ (genome, transcriptome, proteome, metabolome, etc.), the proteome should offer a tight link between genotype and phenotype. Proteoforms, or all of the precise molecular forms of a protein, capture all sources of variability in protein composition (i.e., SNPs, isoforms, post-translational modifications), and thus provide crucial insights into regulation and function. Now, “single ion” mass spectrometry is poised to convert genes to proteoform signatures at a far faster rate. Recently we developed proteoform imaging mass spectrometry (PiMS), with individual ion mass spectrometry. This platform has been extended now to single-cell Proteoform imaging Mass Spectrometry (scPiMS), boosting cell processing rates by >20-fold in the field while detecting proteoforms from single cells.

Abstract: The integration of proteomic technologies into clinical practice indeed holds significant promise for revolutionizing disease diagnosis, prognosis, and treatment. By delving into the intricate world of proteins and their modifications, particularly protein glycosylation, researchers aim to unravel the complexities underlying various diseases.
Glycoproteomics, a specialized field within proteomics and glycomics, focuses on the comprehensive characterization of glycoproteins. In recent years, mass spectrometry-based technologies have emerged as the cornerstone of advancements in glycoproteomics. One of the main challenges in glycoproteomics lies in the heterogeneity of glycosylation of glycoproteins, including variations in glycan types, sites of glycosylation, and the specific glycans attached to each glycosylation site. To overcome these challenges, we have developed various methodologies in glycoprotein glycopeptide enrichment, liquid chromatography, mass spectrometry, and software tools, for precise site-specific glycan assignments.
The developed glycoproteomic techniques offer unprecedented opportunities to investigate the interplay between genomic, environmental factors, and protein modifications. By employing these advanced technologies to investigate tumors, we have gained invaluable insights into cancer biology, particularly pertaining to protein modifications such as glycosylation.
In summary, the integration of glycoproteomic approaches into biomedical research has the potential to significantly advance our understanding of cancer and pave the way for more personalized and effective clinical interventions.
