    Plasma Proteomics - The Dream and the Nightmare

    Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio! On this episode of Translating Proteomics, hosts Parag Mallick and Andreas Huhmer of Nautilus Biotechnology discuss the challenges and opportunities of plasma proteomics. Their conversation focuses on: ·      Why blood plasma may be a good source of protein biomarkers ·      Current methodologies and pitfalls in plasma proteomics ·      The path forward for plasma proteomics What is Plasma Proteomics?For those who are new to this topic, plasma is the liquid portion of the blood distinct from fractions containing red and white blood cells. Given the relatively non-invasive ways physicians can collect patient plasma, and the blood’s intimate association with tissues throughout the body, plasma is potentially an excellent source of protein biomarkers. Yet, it is quite difficult to measure the levels of all plasma proteins because their concentrations span over 12 orders of magnitude. This episode features an in-depth discussion of the ways plasma proteomics efforts have and have not lived up to the promise of biomarker discovery and what we can do to advance plasma biomarker discovery efforts in the future. Chapters00:00 – 01:01 – Intro 01:02 – 4:55 – What is the promise of plasma proteomics? 04:55  – 07:23 – Is the plasma proteome really the best source of biomarkers? 07:23 – 10:16 – How do proteins get into the blood and what are the implications for biomarker discovery? 10:16 – 13:59 – Is it clear that proteins are the best candidates for blood biomarkers? 13:59 – 19:57 – Advances in and the future of comprehensive plasma proteomics 19:57 – 22:31 – Pros and cons of fractionating the plasma proteome to discover biomarkers 22:31 – 28:14 – Progress in identifying multiomic plasma biomarkers and the path forward 28:14 – End – Outro ResourcesNano-omics: nanotechnology-based multidimensional harvesting of the blood-circulating cancerome (Gardner et al. 2022) o   Review from focused on the development multiomics liquid biopsies Multicompartment modeling of protein shedding kinetics during vascularized tumor growth (Machiraju et al. 2020) o   Work from Parag’s Lab investigating tumor protein shedding Simulation of the Protein-Shedding Kinetics of a Fully Vascularized Tumor (Frieboes et al. 2015) o   Tumor protein shedding work from Parag’s Lab Mathematical model identifies blood biomarker-based early cancer detection strategies and limitations (Hori and Gambhir et al. 2011) o   Study modeling how much protein could be shed and detected from different size tumors a href="https://pubmed.ncbi.nlm.nih.gov/12488461/" rel="noopener noreferrer"...

    Protein Function 201 with Kathryn Lilley

    Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio! Proteins adopt a wide variety of functions depending upon factors like their location in the cell, their modifications, and the biomolecules they interact with. While many of us may have been taught that single genes produce single proteins that have single functions, protein function is far more dynamic than that. In this episode of Translating Proteomics, Nautilus Co-Founder and Chief Scientist Parag Mallick sits down with University of Cambridge Professor and proteomics expert Kathryn Lilley to discuss our evolving understanding of protein function. They cover: How they came to realize protein function is more complex than one gene, one enzyme, one functionFactors that give rise to the dynamic complexity of protein function including proteoforms, protein localization, and moonlightingSteps we can take to better understand and teach others about the complexities of protein function Research diving into the complexities of protein functionResearch from the Beltrao Lab using bioinformatics techniques to identify functional phosphosites (Ochoa et al. 2020)Work from the Lilley Lab integrating techniques to investigate ome-wide localization of both RNA and protein (Villanueva et al. 2024)Lilley Lab preprint investigated protein localization changes in a cancer cell line as a result of ionizing radiation treatment (Christopher et al. 2024).Collaborative work with the Lundberg Lab mapping subcellular proteomics (Thul et al. 2017).

    Expanding the Druggable Universe with Proteomics

    Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio! Despite incredible leaps in our understanding of molecular biology, the majority of drug development efforts still fail, and those that succeed often fail to return investment dollars. Proteomics has the potential to change that by providing high-resolution views of the biochemical drivers of biological function - proteins. In this episode of Translating Proteomics, Parag and Andreas discuss how proteomics can help researchers identify good drug targets, personalize drug development, and advance precision medicine. Chapters: 00:00 - How do we define good drug targets and "druggable" in the age of proteomics 08:16 - Advancing personalized medicine through proteomics 10:58 - How proteomics technologies have changed drug development 15:13 - New abilities next-generation proteomics technologies give us in drug development Learn about proteomics and biomarker discovery: https://youtu.be/8rcAxHSRGYs?si=kZ0UX42TJ8tWIaSN Learn more about proteomics and precision medicine: https://youtu.be/bzRlM45agBY?si=eop2XcGLc_oLeiVc

    Why the Dogma around Biology's Central Dogma Is Wrong

    Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio! From high school biology on up, we're taught the central dogma of biology - that biological information flows from DNA to RNA to proteins. This representation of the central dogma is, however, very much a simplification of its original formulation by Francis Crick and over-applying it can lead us down spurious paths and faulty conclusions. In this episode of Translating Proteomics, Parag and Andreas dive into the real meaning of the central dogma and discuss how modern biology research, including proteomics, shows we must drastically alter the ways we use and interpret the central dogma. Chapters: 00:00 – What is the central dogma and how is it misinterpreted? 08:06 – Regulation and control in biology 11:58 – The need for new models in biology

    Single-protein Biomarkers Don't Cut It

    Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio! Protein biomarkers are proteins measured as indicators of biological processes. People often hope biomarkers will take the form of elevated or decreased amounts of single proteins, but few single protein measurements provide specific and sensitive indications of biological processes. In this episode of Translating Proteomics, Parag and Andreas discuss why it is difficult to find new biomarkers and describe how new techniques can enable the development of multi-protein, multi-time point, and even multiomic biomarkers that have more potential than any single protein measurement. Some key points of discussion: Biomarkers are difficult to find because of the methods we use to find them and because there is a ton of variability in natural biological systemsMost proteins are biomarkersWe need more proteome-scale data over space and time to find new biomarkers Learn more about biomarkers.

    Biology in Space and Time

    Do you have a question you'd like answered on a future episode of Translating Proteomics? Send it to translatingproteomics@nautilus.bio! It's no surprise that biological systems change dramatically over space and time, but we often ignore these dynamics when comparing biological samples. In the latest episode of Translating Proteomics, Parag and Andreas discuss why it's essential to take space and time into account and envision ways we can design experiments that explicitly incorporate spacial and temporal considerations. Chapters: 00:00 - Biological systems as dynamic, adaptive systems 04:45 - How current experimental designs rarely take space and time into account 11:54 - The tools necessary to sufficiently measure biology in space and time Some key takeaways from the conversation: Different biological processes occur at very different time scalesComplex, multiomic interactions can only be understood over time and spaceWe need to properly collect, annotate, and share omics-level data in order to understand the rules that govern complex biology Let us know what you think about the podcast.
