Translating Proteomics

On the latest episode of the Translating Proteomics podcast, Nautilus VP of Scientific Engagement and proteomics industry expert Sheri Wilcox joins hosts Parag Mallick and Andreas Huhmer for a thought-provoking discussion of their proteomics "hot takes.”Each “hot take” is a provocative opinion on a topic in proteomics. Specifically, they cover:Insufficient biological validation is one of the biggest problems in proteomics.Antibody validation remains a distributed, inconsistent, lab-by-lab responsibility, and this model for validation may not be sustainable going forward.AI cell models are overhyped.Check out the episode for deep explorations of each of these hot takes and their potential remedies.After listening, be sure to let us know whether you agree, disagree, or have your own hot take to share!

Professor Olga Vitek has a deep understanding of statistics, machine learning, and computational biology. She puts her know-how to work to develop computational tools enabling high-quality proteomic analysis and systems biology approaches. She hopes to apply these tools to the quantitative analysis of large-scale mass spectrometry-based investigations and thereby advance our understanding of organismal function. In this episode, Parag and Professor Vitek discuss:Why statistics is important for experimental designHow statistics and AI can help researchers understand biologyGaps keeping us from using AI and statistics to their maximum potential in biologyResourcesStatistical methods for studies of biomolecular systems websiteOlga’s personal lab websiteBeyond protein lists: AI-assisted interpretation of proteomic investigations in the context of evolving scientific knowledgeGyori and Vitek, 2024 discuss how AI can be used to interpret proteomics data and its biological meaning.A Bayesian Active Learning Experimental Design for Inferring Signaling NetworksNess et al., 2018 show how statistical methods can guide the selection of experiments that optimally enhance understanding

Host Parag Mallick chats with Professor Afshin Beheshti who is a Professor of Surgery, Director of the Center for Space Biomedicine, and Associate Director of the McGowan Institute for Regenerative Medicine at the University of Pittsburgh. In addition, Professor Beheshti has a visiting researcher appointment at the Broad Institute of MIT and Harvard and is president of two non-profits – the COVID-19 International Research Team and Kwaai. The latter aims to democratize access to artificial intelligence through the design, construction, and maintenance of a free personal AI called Kwaai.Professor Beheshti’s research covers a range of topics focused on how circulating mirco RNAs and mitochondria impact health, but this conversation focuses primarily on Professor Beheshti’s work advancing our understanding of how spaceflight impacts biology.

On this episode of Translating Proteomics, Parag speaks with Professor Jennifer Geddes-McAlister from the University of Guelph. Professor Geddes-McAlister is an expert at using proteomics to study host-microbe interactions from a systems biology perspective. Her exciting work spans studies of pathogenic fungi all the way to engineering plants to produce pharmaceutics (so-called “molecular pharming"). On top of all that, Professor Geddes-McAlister also founded “Moms in Proteomics” to support and encourage an intentional focus on the inherently unique physical, emotional, and biological commitments of Mothers, and the ensuing balance required to excel within the diverse STEM fields encompassing Mass-Spectrometry-based proteomics. Dive into this episode to:Learn why it’s critical to study hosts, pathogens, and molecular pharming from a systems point of viewDiscover what Professor Geddes-McAlister is excited about for the upcoming Human Proteome Organization (HUPO) conferenceFind out what “Moms in Proteomics” has planned for HUPOChapters00:00 - Intro01:39 - Professor Geddes-McAlister's initial interest in host-microbe interactions06:13 - Why it's important to study host-microbe interactions08:10 - Pathogens vs helpful microbes10:06 - Thinking about microbes through the lens of "One Health" 14:34 - Why Professor Geddes-McAlister works primarily in proteomics as opposed to other omes19:44 - Professor Geddes-McAlister's favorite thing that she's learned from the proteome and couldn't learn from the other omes24:56 - Molecular pharming29:35 - The need for accessibility in proteomics34:09 - The need for all-in-one workflows in proteomics36:08 - HUPO 202539:56 - Moms in Proteomics42:36 - The future of proteomics43:59 - OutroResourcesGeddes et al., 2015.
