Abstract: Lysosomes and mitochondria are membrane-bound organelles in the cell that are responsible for trash-disposal and ATP production, respectively. Lysosomal and mitochondrial dysfunctions have been linked to numerous human diseases, such as neurodegeneration, cancer, and cardiovascular diseases. These organelles are highly dynamic and frequently interact with other cellular components in a transient fashion, which are difficult to capture with traditional immunoprecipitation and organelle isolation methods. Here, I will describe our recent efforts in developing proximity labeling proteomics, metabolomics, and dynamic SILAC approaches to characterize sub-organelle microenvironment and protein turnover in human iPSC-derived neurons. I will also
introduce our newly established universal and sample type-specific contaminant libraries that can benefit both DDA and DIA proteomics for the broad bottom-up proteomics community.

Abstract: The Open-Port Sampling Interface (OPI or OPSI) presents a flowing solvent stream that can be adapted for direct sampling by mass spectrometry in a variety of formats. In Acoustic-Droplet ejection Mass spectrometry (ADE-MS) the OPI is positioned directly above an acoustic transducer such that nL sample volumes can be ‘ejected’ from 96- or 384-well plates directly into the OPI flow stream for direct ESI-MS/MS quantitative sampling. AE-MS has been applied in a variety of reaction screening applications in drug discovery. We report on our testing of the OPI in two sampling configurations. An AE-MS application that uses a modified EDC ATS-100 acoustic dispenser for High-Throughput screening of a biochemical (TMPRSS2) enzyme assay, and in vertical orientation for direct droplet sampling using a pneumatic aspiration-dispense pumping system. The pneumatic system delivers a pressure-pulse that can eject a 3µL drop cleanly and consistently (6% CV) for direct OPSI-MS sampling.

Abstract: This presentation reveals the profound ways in which isotope ratio mass spectrometry (IRMS) can provide information about the geographic origin and history of almost everything around us, including our fellow humans. The presentation explains, from an atomic/isotopic perspective, the ways in which we are literally what we eat. The talk also explains how researchers use IRMS measurements of hair to determine the geographic origin and travel histories of animals and humans.
Building upon these established capabilities, our research develops the ability to objectively classify the hair of different human donors into soft biometric grouping factors such as biological sex and alcohol consumption or to predict continuous variables like age. Classification is accomplished either through the quantitation of amino acids in the shafts of human hair, which is comprised mainly of structural proteins named keratins, or through the precise measurement of naturally occurring stable isotopes of 13C/12C of each amino acid in the hair shafts. Our work also demonstrates that amino-acid-specific analysis of human hair can predict type II diabetes in the donors. In other, unrelated applications, we use the same methodology to link individual blowflies to their carrion (flesh) diet and to link Eastern oysters to their harvesting areas.

Topic: Soldiers, Slaves, and Cannibalism: Stable Isotope Indications of Historic Life in North America

Abstract: Archaeological studies often include human remains, consisting of only bones and teeth, whose identity has been lost to time. However, with the right biochemical proxies, bones and teeth can yield information about diet, provenance, and demographics of these unknown individuals. The Smithsonian Museum Conservation Institute Stable Isotope Mass Spectrometry Laboratory applies stable isotopes to North American archaeological remains in an effort to better understand the life history and lifestyles of 17th , 18th and 19th century individuals. Examination of carbon, nitrogen, and oxygen stable isotopes from three case studies highlight insights into dietary grain components, geographical provenance and affiliations, meat consumption, and marine dietary inputs. Soldiers from the American Civil War and post-Civil War periods (ca. 1860-1885) show oxygen isotope values indicative of cross-geographical allegiances. Comparative African populations from Ghana show carbon and oxygen isotope values unique to their region, providing means to distinguish enslaved African Americans that were recent arrivals in the Trans-Atlantic Slave trade (late 1700’s). Nitrogen and oxygen isotope values provide insight into the social class and provenance of a young girl cannibalized during the harsh years leading up to Jamestown Colony’s near failure in 1610. All of these examples emphasize the power of this technique to offer some identity to otherwise anonymous individuals, and to provide new insights into our history.
