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 researchProteomics in basic researchTechnology development in proteomicsSynopses 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 proteomicsIn&nbsp;this work&nbsp;from&nbsp;Professor Bernhard Kuster’s Lab&nbsp;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.Find the publication here.Natural proteome diversity links aneuploidy tolerance to protein turnoverAs we discussed on a&nbsp;previous episode of Translating Proteomics, genome alterations often fail to faithfully propagate to the proteome. In&nbsp;this work, researchers from the labs of&nbsp;Professor Judith Berman&nbsp;at Tel Aviv University and&nbsp;Professor Markus Ralser&nbsp;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.<a...

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&nbsp;protein biomarkers. Yet, it is quite difficult to measure the levels of all plasma proteins because their concentrations span over&nbsp;12 orders of magnitude.

Send it to [email protected]!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 functionResearch 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&nbsp;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).Additional protein function resourcesMoonProt&nbsp;- A database for moonlight proteins from Professor Constance Jeffrey's LabTranslating Proteomics Episode 5 - Why the Biology Surrounding Biology's Central Dogma is Wrong
