    The 2018 post-HUPO congress HPP workshop kicked off with a new interactive session moderated by Rob Moritz, where selected senior and young investigators each had <5 minutes to share what they found most exciting during the entire HUPO congress. All speakers strove to beat Rob’s musical interlude, most were successful. The floor was then opened to all participants, with great diversity of inputs and interests. This new format was a refreshing and productive start to the workshop.

    The HPP Town Hall Meeting session led by Fernando Corrales and Young-Ki Paik outlined the activities and goals for the B/D- and C- HPP, respectively. Mark Baker then presented his vision and strategic plan for the NextGen HPP, with input and discussions from the senior Scientific Advisory Board (SAB) members, Cathy Costello, John Yates and Naoyuki Taniguchi. Although the B/D- and C- HPP branches were organised for logistics in the first phase of HPP, synergistic efforts are being established between various B/D- and C- HPP teams. The SAB further challenged the NextGen HPP leadership team to aim for HPP integration in the coming years.

    With the establishment of the Pathology pillar, HPP is inviting external interdisciplinary partners towards clinical translation. Steve Pennington and Henry Rodriguez shared their views and experiences on the strategies for successful international translational research. Finally, Mike Synder delivered insightful grand challenges for the entire field of proteomics.

    The post-congress workshop ended on a high note with celebration of Gil Omenn’s leadership of HPP, with refreshments. The well-researched presentation by Mark Baker provided a rare insight to the talents and achievements of Gil.

    With a good attendance at the Thursday HPP workshop, talks on the Knowledge Base Pillar progress and outlook were well presented by Eric Deutsch, Lydie Lane and Henning Hermjakob. They highlighted the raw MS data exchange between ProteomeXchange and partners such as Pride, iProx, JPOST, MassIVE and Panorama, which serves to collect all public proteomics data generated by the scientific community, protein evidence status in PeptideAtlas and neXtProt according to the latest release. The report also gave updates on the peptide uniqueness checker and introduction of Universal Peptide Identifier that aims to identify specific MS/MS spectra in a ProteomeXchange dataset.

    Measurement of intact proteoforms with top-down approach to map the proteome of human cell types (a Cell-Based Human Proteome Project) was presented by Neil Kelleher. In discussions with the Chairs of the C-HPP a collaboration has been formalised to prepare a proposal for the C-HPP and HPP ECs titled “The Human Cell Proteome Atlas”. This is an extension of the current rare cells and tissues project of the C-HPP led by Chris Overall. In the HCPA the current bottom up rare cells and tissues proteomics projects of the C-HPP would be complemented by the a top-down proteomics approach led by Neil to produce an atlas of proteins and proteoforms making up each of the hundreds of different cells of the human being.

    On emerging technology topics, Bonghee Lee (Korea) presented CRISP/cas9 technology used to modify human iPSC and differentiated cells for Hemophilia B treatment . Janne Lethiö (Sweden) presented proteogenomics pipeline that can be used to process high-resolution iso-electric focusing fractioned peptides to better annotate protein coding region of the human genome and identify variants in human blood. Mike Snyder presented ‘Grand Challenges for the Entire Field of Proteomics’ where he addressed an outlook and plans on the directions of the proteomics technology development and those key issues that the HPP will address in the future. Henry Rodrigez showed an overview on the international collaboration within Cancer Human Proteome Project and within the Cancer Moonshot international collaboration. Mark Baker, incoming HPP Chair (Australia) outlined his strategic plans on the key HPP components, C-HPP and B/D-HPP in the next 2 years. The Antibody Validation Initiative showed their progress to develop validated antibody reagents for the scientific community. The September/October neXt-MP50 report from the Chromosome Teams was presented to the HUPO council. The chromosome teams reported the identification of ~401 missing proteins identified according to the C-HPP guidelines in 2018. These were presented in 26 J Proteome Res Special Issue papers in December 2017 and will be reported in 34 J Proteome Res papers in the upcoming December 2018 Special Issue. In addition, the Chromosome Teams reported HPP findings in 63 other papers in 2018, many of which reported missing proteins or uPE1 functionalization. At the end of the first quarter 2019 the next builds of the Peptide Atlas and NeXtProt will have parsed through these and other Proteome Exchange data sets for confirmation of found MPs.

    Other News

    The C-HPP welcomes the leadership of Dr. Rob Moritz, Institute of Systems Biology, Seattle, WA as the new leader of the Chromosome 6 Team, that has passed from Christoph Borchers, University of Victoria. The experimentalists, coders and data-base curators at ISB are a welcome addition to the C-HPP and join active labs at the University of British Columba, Vancouver, in a “Cascadia Chromosome Collaboration”.

    Plans are moving forward for the 21st C-HPP Project Symposium, to be held May 12-14, 2019 in Saint Malo, France. Focussing on “Illuminating the Dark Proteome” the symposium will be an important milestone for the uPE1 project and will include speakers from the B/D-HPP on functionalizing the dark proteome. What is also certain, the cuisine at this meeting will not be dark or need illumination thanks to Charles Pineau, Chair of the workshop.

    A total of 57 attendees –including 41 academics and 16 delegates from the industry– from 19 different countries gathered together at the Spanish National Biotechnology Centre in Madrid for the 1st HIPP Summer School on Immunopeptidomics. To provide students with a critical understanding of the challenges and experimental strategies in immunopeptidomics, the contents of the Summer School were structured around three fundamental topics: sample preparation, LC-MS/MS analysis and bioinformatics and data sharing. The course encompassed keynote talks by recognized experts in the field, training lectures and poster presentations by the participants. Additionally, it also included a dedicated session to promote networking with representatives from companies actively working in the area of immunopeptidomics.

    Organizing Committee and Sponsors

    The 1st Summer School on Immunopeptidomics was organized by the following members of the HIPP initiative: Nicola Ternette (University of Oxford, Oxford, UK), Stefan Tenzer (University of Mainz, Mainz, Germany), Miguel Marcilla (Spanish National Biotechnology Centre, Madrid, Spain), Fabio Marino and Michal Bassani-Sternberg (both from the Ludwig Institute, Lausanne, Switzerland). In addition, the organization of this event was possible thanks to the financial support of Agenus, Genentech, Bioinformatics Solutions, the Spanish Proteomics Network (ProteoRed) and the HIPP.

    Final Remarks and Future Editions

    This Summer School proved to be an ideal setting for discussion and exchange of ideas allowing young researchers to meet renowned experts as well as to interact with delegates from companies. Based on the results of a survey completed by the participants, the overall perception of the quality of the course was high and it fulfilled the expectations of both the attendees and the organizers. Considering its success, HUPO-HIPP is promoting the organization of a new edition of the Summer School to be held in one or two years´ time.

    The annual meeting of the C-HPP and C-HPP PIs (PIC) was held  at HUPO 2018 in Orlando, Florida. The meeting was very well attended by members and PIs. A progress report on the next-MP50 was prepared before the meeting and will be updated when all reports have been submitted and uploaded to the C-HPP Wiki. Several important decisions were made after extensive discussions. Following Young-Ki Paik’s Paik (Yonsei University) proposal to rotate the leadership of C-HPP. Chris Overall (University of British Columbia) was unanimously elected as C-HPP Chair. Young-Ki was then elected as the new Co-Chair with Lydie Lane continuing her current position as shared Co-Chair of C-HPP Executive Committee (EC).

    Collaborations with B/D-HPP. To further the collaborations with the B/D-HPP, the membership of the C-HPP agreed that the uPE1 project was ideal to combine with the talents and resources of the B/D-HPP, and in discussions with the B/D-HPP leadership this too was agreed (see Figure, noting that for clarity the Pillars etc. are not shown). Relevant papers in the JPR SI can be found in PMID 30269496.

    Human Cell Proteome Atlas. As part of the rare cells and tissues strategy to find MPs, a parallel value-added project to annotate the proteins of specific normal human cell types received considerable support with the view of creating a Human Cell Proteome Atlas that would be done in collaboration with B/D-HPP. The aim of the HCPA is to annotate the proteomes of normal human cells (fresh prepared or low passage number primary culture) so as to provide an authorative and convenient single lookup data base that would complement the other resources based on antibodies (Human Protein Atlas), Cellosaurus, and various genetic based resources. During HUPO the C-HPP initiated discussions with Dr. Neil Keller to bring this proposal to the HUPO EC for discussion and approval.

    C-HPP 2.0. Deep discussions took place on a proposed “chromosome-rearrangement” of the working nucleus of the C-HPP, which had been floated to the membership at the Santiago C-HPP workshop on 23rd June. The proposed new structure, as part of “C-HPP 2.0”, would collapse the number of national Chromosome teams by approximately half based on their activities. Freed-up C-HPP team members would remain as members at large or nucleate bottom up to form new annotation C-HPP annotation teams based on protein families, cell types, or new technologies. Such teams would have equal standing with those teams wishing to remain chromosome based.

    Following further discussion, the membership clearly expressed their wish and desire to pursue their national projects under the current chromosome-organised structure. Points brought up included that Chromosome teams very much liked having a recognised national “brand” as a platform to nucleate like-minded labs and centers to work collaboratively together, importantly a Chromosome “face” was valuable to interface more effectively with Universities, Funding Agencies and Governments. It was also expressed that this structure was the most effective to support the current projects, many of which are in fact chromosome orientated, i.e. finding missing proteins (neXt-MP50), discovering uPE1 protein functions (neXt-CP50), and to maintain funding and salaries by some teams that have secured significant operating funds. Members of the Italian Mt team proposed an innovative cross matrix solution that has been drawn in the figure, that was greeted with great enthusiasm as meeting the new needs and scientific objectives of the C-HPP under the HPP umbrella.


    A motion to retain the existing Chromosome Structure was seconded and put to the vote, which was carried unanimously.

    Bioinformatics Hub. In other activities at the bioinformatics hub shared great interactions between the leaders of the main HPP resources and tools (ProteomExchange, PetideAtlas, MASSIVE, neXtProt and HPA) in order to make the most of the available data and complete the annotation of the human proteome parts list.

    Annual C-HPP Workshop. The annual C-HPP workshop entitled: “Illuminating the Dark Proteome” has a major goal to advance uPE1 functionalization in the next-CP50 project. The workshop is organized by Charles Pineau in collaboration with Chris Overall and Fernando Corrales. The workshop will take place in Saint-Malo, France, a historic city on the Brittany coast (France), from 12 to 14 May 2019, with the hotels within the actual historic citadel and featuring excellent French cuisine and wines.

    Michelle Hill, QIMR Berghofer Medical Research Institute, and The University of Queensland, Australia

    Launch of the HPP Pathology Pillar at HUPO2018 was met with great enthusiasm, particularly with the clinical scientist and pathologist travel grant winners. “I was very excited to learn about the establishment of the new Pathology Pillar of the Human Proteome Project”, said Kun-Hsing Yu (Department of Pathology, Brigham and Women’s Hospital and Department of Biomedical Informatics, Harvard Medical School, USA). Peter Stewart’s (Royal Prince Alfred Hospital Sydney) advice to tackle the “low-hanging fruit”, as a strategy forward particularly struck a chord with Yunki Yau (Gastroenterology Department, Concord Repatriation General Hospital, AUSTRALIA): ‘By improving on current clinical tests that aren’t satisfactory with proteomic techniques and technology, we can foster confidence in our workflows in the wider clinical community.”

    The seven travel grant winners, the pathology pillar leaders and the Biology Disease Human Proteome Project Executive Committee members had a productive roundtable meeting in Orlando. HUPO Young Gun, ECR member and clinician-scientist Ferdinando Cerciello (Department of Oncology, University Hospital Zurich, Switzerland) moderated the discussion.

    In-depth discussions ensued around the topic “Can proteomics speed up drug discovery?””, posed by Ferdinando. Danni Li (Director of Clinical Chemistry, Department of Laboratory Medicine and Pathology, University of Minnesota) posed the thought-provoking question, what is proteomics? “To me, proteomics is to measure proteins. In this definition, proteomic technologies have been used for drug discovery for a long time.”, said Danni. Yunki Yau agrees. “Are we fundamentally interested in making MS-based protein assays a clinical instrument? Or do we essentially want clinical legitimacy for protein biomarkers and drug targets, no matter how we do it?” Jesper Kers (Department of Pathology, University of Amsterdam & VU University Amsterdam, The Netherlands) also voiced the point “Clinical proteomics should be driven by clinician’s unmet needs, because they are the most important potential end-users of the technique.”

    In addition to the current strategy of engaging clinicians & pathologists, there was agreement on the importance of engaging the pharmaceutical companies in future HUPO meetings. Michael Roehrl (Department of Pathology, Memorial Sloan Kettering Cancer Center, New York, USA) suggested that “we all need to engage directly with biotech and pharma to make functional proteomics a key strategy for the next generation of companion diagnostics.”

    Several clinician scientists and pathologists strongly agree with the need for standardization and automation, which was highlighted by several speakers during the HPP track session: Partnering with Pathology Towards Precision Medicine. “I think the HUPO pathology pillar can play a crucial role in standardization of proteomics assays among laboratories in order to assure high quality and reproducible results.”, says Jesper Kers.

    Ferdinando’s second discussion point “Can next-gen proteomics biomarkers be as good or better than current imaging/diagnostics?” brought additional discussions around reimbursement and funding of clinical tests. There was general agreement that proteomics can and should add value to the existing tests, with opportunities and strategies to cross barriers discussed in detail. Jesper Kers suggests that “An example where I think mass spectrometry can have an additional value over DNA sequencing is holistic profiling of immune responses, in both the setting of oncology and immunometabolic diseases.”

    As 90 minutes quickly passes, Jennifer Van Eyk (Cedars Sinai Medical Center) suggests the preparation and publication of a white paper on the key points and conclusions, as a way forward. With support from the group, Michael Roehrl graciously agrees to lead this endeavour. “We need to work as a community to firmly establish proteomics as the new frontier of theragnostic molecular testing in pathology”, says Michael. From the roundtable and HUPO congress, Margaret Simonian (University of California Los Angeles) was inspired to collaborate between all omics, clinicians and scientist “to advance treatments and diagnostics in clinical medicine and precision medicine.”

    The Human Proteome Project (HPP) MS-Pillar Phosphopeptide challenge resource continues to collect new data and invites new participants to also contribute to this knowledgebase. Participants are invited to contribute to both phases of phosphopeptide identification methods development by analyzing a set of phosphopeptides by their favorite method and follow up with a method of affinity purification step using the popular ReSyn HUPO affinity kit to see improvements in their methods. Together with our partners, SynPeptide Co. Ltd in Shanghai (www.synpeptide.com) and Resyn Biosciences Pty Ltd in South Africa (www.resynbio.com), the HPP MS-Pillar will provide the SynPeptide-HUPO phosphopeptide mixtures as well as a comprehensive ReSyn phosphopeptide purification kit to use as the affinity method for the HUPO phosphopeptide mixtures. The SynPeptide phospho peptides and the Resyn MagReSyn® kit including the magnet separator are valued at over US$1000 each are provided free to all interested HUPO members.

    The MS-Pillar Phosphopeptide challenge samples are a complex set of human phosphopeptides (Ser, Thr or Tyr) singly and multiply phosphorylated) and their unphosphorylated counterparts that can be used for method development and verification for phosphopeptide enrichment, sequence analysis by mass spectrometry and bioinformatic evaluation.

    The first stage of this initiative is for interested members of the HUPO community to obtain a set of the peptides and apply their own methods and bioinformatic analysis to fully characterize the peptides as a neat mixture and in a tryptic digest background. Samples are still available by contacting the email below.

    The second stage is now to compare your methods used with the Resyn purification kit for phospho-enrichment and peptide clean-up. The kit contains 2mL of each MagReSyn® Ti-IMAC, Zr-IMAC, and HILIC, and 4-place magnetic separator. As a result of this collaborative endeavor, multiple purification schemes, analytical protocols and data processing strategies will be evaluated, making it possible to determine the approach(es) that provide the highest coverage of phosphopeptides in the mixture.

    By partnering with Resyn and SynPeptide, the HPP MS-pillar has combined the peptide sets and affinity purification kit free-of-charge to all HUPO members, with the understanding that the analytical and data processing methods and results will be returned to the HPP MS Resource Pillar committee, so they can be collated, combined with the HUPO 2018 data, and reported at the HUPO 2019 meeting.

    The HUPO phosphopeptide mixtures Peptides and iMac kits can be picked up from SynPeptide and Resyn at their booth at HUPO 2018 Orlando.

    The Cardiovascular BD-HPP Initiative welcomes a new era of precision medicine that capitalizes on future-forward proteome technologies to identify cardiovascular disease mechanisms and therapeutic targets. Proteome signatures have gained recognition as the main driving force in cellular phenotypes, and several extraordinary and quantitative innovations can now elucidate these dynamic fingerprints at unprecedented speed, sensitivity, specificity and scale. Significant advancements that are forging new heights in proteomic analysis include new multiplexed mass spec sample preparation workflows and developments in novel, quantitative phospo- and splice variant proteoform resolution using top-down mass spec technologies.

    New and exciting data from Ying Ge’s laboratory unveiled the complex proteoform profile of cardiac Troponin T (cTnT), a critical thin filament regulatory molecule of cardiac contraction/relaxation and clinical biomarker of myocardial infarction. Using online liquid chromatography and immunoaffinity purification coupled to high resolution top-down MS and several complementary fragmentation approaches (CAD, ECD, ETD), they were able to unequivocally identify seven unique cTnT splice variants, each in an unphosporylated or mono-phosphorylated form. This study represents the unprecedented power of top-down MS in isolating various intracellular proteoforms that likely elicit distinctive biological functions.

    Exciting work by Jennifer van Eyk’s group includes the development of a streamlined, multiplexed workflow that enables the processing of 96 complex biological samples for MS in a matter of 5 hours. This methodology demonstrated remarkable reproducibility for both plasma and serum samples, showcasing CV’s less than 20% and holding up across replicates, days, instruments, and laboratory sites. Overall, this valuable approach will empower the proteomics community with tools to minimize artefactual introductions and enhance the native biological presentation of peptides during MS analysis. Moreover, we are seeing unparalleled developments in multiplexed, aptamer-based technologies which now target nearly 5000 proteins in biofluids. A collaborative study between Robert Gerszten and Lori Jenning’s groups demonstrated the application of this method to identify circulating biomarkers for myocardial infarction in derivation and validation patient cohorts, with orthogonal technical validation using targeted mass spectrometry

    Computational innovations incorporating global proteome dynamics into data science platforms have emerged. The integration of transcript abundance, protein abundance, and protein turnover data and the extraction of multi-dimensional molecular signatures affords a 75% gain in discovering disease gene candidates. These recent developments in data science tools will facilitate protein marker discoveries, including clustering as well as signature extraction.

    In summary, new technologies are paving the way to resolving comprehensive, spatio-temporal, dynamic maps of cardiovascular and other organelle proteomes that expand and articulate our understanding of how protein networks propel myriad phenotypes. Capitalizing on this knowledge to ultimately reduce the number of cardiovascular disease-related deaths is truly on the horizon.

    Gilbert Omenn, University of Michigan, Michigan

    The HUPO Human Proteome Project (HPP) annually reports on progress throughout the field in credibly identifying and characterizing the human protein parts list and making proteomics an integral part of multi-omics studies in medicine and the life sciences. neXtProt release 2018-01, the baseline for the 6th annual HPP special issue of the Journal of Proteome Research, contains 17,470 PE1 proteins, 89% of all neXtProt predicted PE1-4 proteins, up from 17,008 in release 2017-01 and 13,975 in release 2012-02. Conversely, the number of neXtProt PE2,3,4 missing proteins has been reduced from 2949 to 2579 to 2186 over the past two years. Of the PE1 proteins, 16,092 are based on mass spectrometry results, and 1378 on several other kinds of protein studies, notably enhanced by protein-protein interaction findings. PeptideAtlas has 15,798 canonical proteins, up 625 over the past year, including 269 from a major study of SUMOylation as a post-translational modification. The major limitations in finding expression of the remaining PE2,3,4 missing proteins continue to be protein sequences that cannot yield two proteotypic uniquely-mapping non-nested tryptic peptides of > 9 aa; lack of expression of the corresponding transcript in tissues studied; and especially concentrations of proteins too low to be detected even with the most modern mass spectrometers. Enrichment of low-abundance proteins, recognition of semi-tryptic peptides, and analysis of unusual tissues, especially with evidence of transcript expression, offer avenues to find more missing proteins.

    Meanwhile, the Chromosome-centric HPP has launched an initiative to characterize the 1260 PE1 proteins that presently lack functional annotation. The HPP Mass Spectrometry resource pillar is conducting a multi-lab analysis of a standard sample with 96 phosphopeptides. The Human Protein Atlas has released its Cell Atlas, Pathology Atlas, and updated Tissue Atlas, and is applying recommendations from the International Working Group on Antibody Validation. A new resource pillar for Pathology to link with clinical translation has been launched. Finally, there is progress applying the quantitative multiplex organ-specific popular proteins targeted proteomics approach in various disease categories.

    Péter Horvatovich, University of Groningen, Netherlands

    The 19th C-HPP Symposium/workshop organized by Fernando J. Corrales, Concha Gil and Young-Ki Paik was held in conjunction with EuPA 2018 Congress with a scientific theme, “Translating Genome into Biological functions”. In this meeting, 13 Chromosome teams (Chr 2, 5, 6, 9, 11, 13, 14, 15, 16, 17, 18, X and Mt.) presented their work-in progress on missing protein identification and uPE1 (PE1 proteins of unknown function) characterization. Beside the talks mentioned in July 2018 C-HPP HUPOST, in the session of next-CP50 challenge, Gilberto B Domont presented latest data on brain proteomics of fetus bearing Congenital Zika Syndrome. Results indicate that lower expression of proteins compromises the vascular system and upper expression directs the cell machinery for virion production by enhancing neurogenesis, energy generation and protein synthesis. In the Young investigator session, Aida Pitarch from Complutense University (Madrid, Spain) presented a 2D gel-based proteomics approach to identify the molecular mechanisms of the human/host immune response induced by infection with Candida albicans. Juan Antonio Vizcaino, from the European Bioinformatics Institute (EBI) provided an update on ProteomeXchange and recent works done at EBI to reuse and integrate public proteomics data, focusing on multi-omics and proteogenomics data integration and multi-omics datasets available at the EBI data repositories. The talk presented ‘Novel ProBAM and ProBed formats facilitating proteogenomics data integration and the OmicsDI portal (http://www.omicsdi.org/)’ which collects multi-omics datasets. Peter Horvatovich from University of Groningen presented a study assessing the bias in proteomics sample preparation of head and neck tissues such as nasal polyps, parotid gland, and palatine tonsils using fours widely used sample preparation protocols (in-gel, in-solution, on-filter, and on-pellet digestion). The study was using MRM based targeted and DDA discovery LC-MS/MS proteomics profiling and concluded that there is no universal sample preparation protocol, which is best for all tissue with respect of relative losses and discovery potential. Charlotte Macron from Nestlé Institute of Health Sciences described identification of missing proteins such as protein dispatched homolog 3, Augurin, Erythroferrone, Protocaderins from cerebrospinal fluids of Alzheimer patients using deep proteomics and TMT labeling. Miguel Marcilla from Complutense University presented the identification of missing protein of Hyaluronan synthase 1 (HAS1) in Human Mesenchymal Stem Cells Derived from Adipose Tissue and Umbilical Cord using deep proteomics fractionation with SDS gel electrophoresis and basic reverse phase fractionation. Bioinformatics (e.g. text mining, online resource of orthologous genes) and wet lab workflows (e.g. gene silencing with siRNA and CRISPR-cas9) to find function for uPE1 proteins of chromosome 13 was presented by Seul-Ki Jeong (Yonsei Proteome Research Center). The complete program of the workshop with presented materials which we received consent from the authors is available at C-HPP Wiki
