Tau proteoform analysis – Key takeaways from our recent Nature Methods publication
Translating Proteomics hosts Parag Mallick and Andreas Huhmer discuss our new Nature Methods paper, “Large-scale single-molecule analysis of tau proteoforms.” This publication describes how the Nautilus Voyager™ Platform can be used to quantify proteoforms derived from the neurodegeneration-associated tau protein. These proteoforms are defined by their unique combinations of post-translational modifications and isoform specific sequences. They may make powerful next-generation biomarkers or drug targets, but few technologies can measure them today. In the episode, Parag and Andreas discuss: What proteoforms are and why it’s critical to study them to understand biology. How the Nautilus Voyager™ Platform quantifies proteoforms. The key findings from the tau proteoform analyses in the paper. Potential applications of these findings. The Nautilus Voyager™ Platform as a powerful foundational technology.

Proteomics Hot Takes with Sheri Wilcox, Andreas Huhmer, and Parag Mallick
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!

2024 Year-End Special: 3 Exciting Examples of Proteomics Research
On this special, year-end episode of Translating Proteomics, hosts Parag Mallick and Andreas Huhmer discuss three of their favorite proteomics publications from 2024. They'll cover one paper in each of the following topic areas: Proteomics in pre-clinical research Proteomics in basic research Technology development in proteomics Synopses of each of the papers can be found below and you can find many more insights in the podcast. Decrypting the molecular basis of cellular drug phenotypes by dose-resolved expression proteomics In this work from Professor Bernhard Kuster’s Lab at the Technical University of Munich, researchers assess protein abundance changes that result from treating Jurkat acute T cell leukemia cells with 144 drugs over five drug doses. The researchers use their proteomic data to generate millions of dose response curves for the thousands of proteins measured and discover that the drugs impact many more proteins and pathways than those identified as drug targets. In addition, they checked how 7 of the drug treatments impacted the transcriptome and found there was often discordance between impacts at the mRNA level and the protein level. This works highlights the many ways drugs can impact biological systems and suggests that similar studies will help researchers understand the effects of drug treatments and may even aid in the development of more effective or more specific therapies.

Natural proteome diversity links aneuploidy tolerance to protein turnover As we discussed on a previous episode of Translating Proteomics, genome alterations often fail to faithfully propagate to the proteome. In this work, researchers from the labs of Professor Judith Berman at Tel Aviv University and Professor Markus Ralser at the Charité - Universitätsmedizin Berlin, investigate the means through which yeast strains adapt to chromosome gains or losses (aneuploidy). They assess the concordance between changes in mRNA and protein expression in aneuploid yeast that were either found in nature or generated in the lab. The researchers observed dosage compensation, a tendency to return to expression levels associated with normal chromosome numbers, for both mRNAs and proteins expressed on aneuploid chromosomes. However, dosage compensation was much stronger at the protein level than the mRNA level and even stronger at the protein level in naturally aneuploid strains compared to lab-generated strains. This work suggests that multiomics efforts are necessary to determine the effects of genomic alterations. In addition, the authors find that protein degradation, as observed through increased ubiquitination, increased turnover of proteins encoded in aneuploid chromosomes, and the up regulation of the proteasome complex, is a key means of dosage compensation. Finally, because the naturally aneuploid strains achieved a higher level of dosage compensation than the lab-generated strains, the authors suggest there has been selection for natural aneuploid strains that down-regulate proteins causing detrimental effects.

Nanopore-based sequencers thread single protein molecules through tiny pores imbedded in membranes. Changes in the electrical properties of the pores due to protein threading can theoretically be measured to sequence the threaded proteins. To date, the complex signals coming from full protein molecules cannot be effectively interpreted to determine complete protein sequences. In this work from Professor Jeff Nivala’s lab at the University of Washington, researchers bring the field one step closer to full protein sequencing by showing they can use nanopore-based devices to effectively conduct long reads and identify single amino acid substitutions in repetitive protein sequences with otherwise highly similar readouts. In addition, they develop a method that makes it possible to conduct repeated reads of the same protein molecule and thereby improve read accuracy. They leverage their methodology to show they can design protein barcodes, identify PTMs on otherwise identical protein molecules, and identify traces indicative of particular proteins. While they do not sequence full proteins, these researchers suggest their techniques can be used for proteoform identification and the creation of millions to billions of individually distinguishable barcodes.

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. Chapters 00:00 – 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 Resources Nano-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 The human plasma proteome: history, character, and diagnostic prospects (Anderson and Anderson 2002) o Review discussing the clinical importance of the plasma proteome and the wide range of protein abundance in the plasma proteome Blood Biomarkers to Detect Alzheimer Disease in Primary Care and Secondary Care (Palmqvist et al. 2024) o An example of the potential power of blood plasma as a source of biomarkers Plasma Proteome Project
