What do our collaborators say about the OPL?
Quotes from CCA collaborators:
Dr. Jacqueline Cloos, Dept. Hematology, collaborator since 2012:
“De afdeling Hematologie heeft samen met het OPL een aantal mooie studies lopen waar al heel interessante data uit zijn gekomen. Kroon op het werk is een artikel in Molecular and Cellular Proteomics waarin we laten zien dat leukemiecellen blaasjes uitscheiden met daarin met name eiwitten betrokken bij splicing. In een ander succesvol project karakteriseren we specifiek het tyrosine fosfoproteoom van verschillende leukemiecellen om aan de hand van deze profielen de juiste kinase remmers te selecteren voor het behandelen van de patiënt. Naast de technische support bij de experimenten krijgen we gelukkig ook veel support voor de data analyses om de biologische significantie te vinden in de grote datasets.
Omdat de (gefosforyleerde) eiwitten veel zeggen over de functionele processen in de cel is proteomics een mooie aanvulling op de genomics en transcriptomics en zullen we ook in de toekomst nog veel gebruik maken van deze faciliteit.”
Dr. Linda Smit, Dept. Hematology, collaborator since 2014:
Mijn onderzoeksgroep is op zoek naar eiwitten die gebruikt kunnen worden als therapie doelwitten en de terugkeer van leukemie kunnen voorkomen. De proteomics faciliteit geleid door Connie Jimenez heeft al een fantastische bijdrage geleverd aan dit onderzoek door proteomics te doen op de cellen die verantwoordelijk zijn voor de leukemie terugkeer. We hebben op deze manier al verschillende eiwitten geïdentificeerd die mogelijk gaan leiden tot een nieuwe therapie die de overleving van leukemie patiënten gaat verbeteren.
Dr. Michiel Pegtel, Dept. Pathology, collaborator since 2007:
De Exosomens research group (ERG), is een multidisciplinaire onderzoeksgroep van het VUmc die internationaal bekend staat om baanbrekend onderzoek naar exosomen en de rol die deze nanoscopische vetblaasjes spelen in kanker en autoimmuniteit. Sind de start van dit laboratoriumonderzoek zijn met behulp van massaspectometrie en innovatieve data-analyse methodes met behulp van en ontwikkeld door het OPL verschillende nieuwe fundamentele inzichten verkregen. Recent heeft dit geleid tot een publicatie in PNAS waarin werd aangetoond met massaspectometrie dat RNA-bindende eiwitten een inhiberende rol spelen in ontstekingen veroorzaakt door uitgescheiden RNA moleculen. Tevens is met behulp van de kwantitatieve analyse methode van het OPL ontdekt dat druggable ‘membraan fusie’ eiwitten oncogenese bevorderen omdate deze ongecontroleerde exosomen productie in kankercellen ‘aan’ zetten. Het is de verwachting dat door middel van nieuwe isolatietechnieken mede ontwikkeld door het ERG in combinatie met gevoelige eiwit detectie technieken van het OPL nieuwe diagnostische testen kunnen worden ontwikkeld voor kanker en auto-immuniteit met een superieure sensitiviteit en specificiteit.
Dr. Irene Bijnsdorp, Dept. Urology, collaborator since 2012:
Research of the Dept. of Urology focusses on protein marker identification for detection and stratification of prostate cancer patients into risks groups. To this end we analyze small extracellular vesicles (exosomes) that have emerged as biomarker-rich treasure troves. Together with dr. C. Jimenez of the OPL, we profiled the proteome of urinary exosomes leading to the identification of over 3000 proteins. This is much more than has been identified before by others (usually not exceeding 1500 proteins). Initial proof-of-concept proteomics profiling led to the improvement of exosome isolation of urine EVs. Furthermore, after data mapping and key (bio)statistical support provided by the OPL-group, led to the identification of potential PCa biomarkers. This work was the basis for the financial support (KWF, Alpe d’Huzes) of a collaborative project together with Prof. Jenster (Erasmus MC) and Prof. Schalken (Radboud UMC). This project will take advantage of the excellent infrastructure and expertise in exosome-proteomics (Dr. Jimenez) and it is expected that this project will provide a strong basis for developing a liquid biopsy-based diagnostic/prognostic test for PCa.
Prof. Ruud Brakenhoff, Tumor Biology section of the Dept. Otolaryngology-Head and Neck Surgery, collaborator since 2010:
The Tumor Biology lab focuses its research on the diagnosis and treatment of patients with tumors in the upper aerodigestive tract. Using genome-wide siRNA screens we identified a variety of novel molecular targets that might be exploited to improve future therapy protocols, combined with standard first line treatments. One of the major research efforts is to elucidate the molecular pathways these drug targets act in, and using (phospho)proteomics approaches both primary and secondary substrate proteins can be identified, and the effects of inhibitors analyzed. This was recently published for the MASTL protein, a kinase that sensitizes lung cancer cells for radiotherapy (Nagel et al. Mol Cancer Ther 2015). This work will certainly be followed up for targets and inhibitors being studied, and proteomics and phosphoproteomics are the ideal pipelines for such studies.
Dr. Josephine Dorsman, Dept. Clinical Genetics, collaborator since 2010:
“Het is goed om in-huis een kOPLoper in protemics te hebben, om nieuwe inzichten & OPLossingen te vinden voor basale en translationale vragen. Ook daadwerkelijk gebeurd in samenwerking: Fanconi & Zuurstof tolerantie ! Omdat het juist de eiwitten in de cel zijn die het werk doen, verwachten wij dat het OPL onderzoek nog veel gaat OPLeveren in de toekomst.”
Dr. Rob Wolthuis, Head of the Oncogenetics Labs, Dept. Clinical Genetics, collaborator since 2015:
“In the era of cancer -omics, we see two critical developments: the first one is directed at resolving biological and clinical implications of cancer mutations. Already at an early stage, Connie Jimenez started to address these by effectively exploiting a combination of cancer genomics and proteomics. Secondly, there is an enormous need for new combination therapies that could overcome drug resistance associated with targeted mono-therapies. This absolutely requires advanced molecular pathway analyses and functional kinase studies, which are technically very challenging. The Jimenez lab has generated powerful new assays for rapid phosphoproteomics and links them to state-of-the art bioinformatics, a great combination. With these expertises in full operation, the lab functions at a state-of-the-art international level now, and has tremenduous value for cancer research at the CCA. We look forward to continuing our various research lines with the OPL"
Dr. Juan Vallejo, Dept. Molecular Cell Biology & Immunology, collaborator since 2015:
“At the group of Dendritic Cell Immunobiology we focus on the role of glycan-binding receptors on the modulation of immune responses and their potential use as targeting receptors for anti-cancer vaccination. One of the most interestign features of these broad family of receptors is that, besides mediating efficient antigen uptake, they also trigger intracellular signaling that modulatest dendritic cell activation. However, the nature of the signaling events involved in this pathway remains only partly uncovered, and next generation phosphoproteomics will be extremely useful in shedding light on this processes.”
Prof. Wilbert Bitter, Dept. Medical Microbiology, collaborator since 2006:
“The proteomics facility of the OPL has been crucial for our work on the tubercle bacillus. We have generated various secretion mutants and the detailed proteomic analysis of these mutants has shown important new insights in the working of this major pathogen. The high-end equipment and expertise of the OPL researchers in the data processing helped us to place ourselves in the forefront of tuberculosis research. Especially because some of the most important proteins turned out to be extremely challenging to capture by proteomics. This work has resulted in 8 publications including papers in PloS Pathogens and PloS Genetics, as well as in new strategies for vaccine development.”
Prof. Arjan Griffioen, Dept. Medical Oncology, collaborator since 2014:
‘The Oncoproteomics Laboratory very successfully assisted several projects that are currently running in the Angiogenesis Laboratory. Proteomics approaches were applied in the search for alternative isoforms of the tumor vascular marker vimentin and for the discovery of diagnostic biomarkers present in cancer patient thrombocytes. The expert collaboration has been efficient, fast and successful. A future collaborative project will focus on the mechanisms of targeted combination therapy by phophoproteomics.’
Drs. Mariette Labots M.D., Dept. Medical Oncology (clinical staff), collaborator 2012:
Als medisch oncoloog leg ik patiënten met uitgezaaide kanker dagelijks uit hoe targeted therapies werken. En ook dat we op voorhand niet weten of de behandeling wel zal aanslaan, of, dat als deze blijkt te werken, op termijn meestal toch ongevoeligheid zal ontstaan. Vaak vraag ik om toestemming voor het nemen van een tumorbiopt voor onderzoek: omdat we samen met het OPL hard werken aan een (fosfo)eiwittest om in de toekomst te kunnen bepalen welke signaleringsroutes actief zijn in de tumor, om hiermee de meest geschikte behandeling te kunnen selecteren voor een individuele patient.
Zo hebben we in de afgelopen jaren de voor personalized medicine veelbelovende fosfoproteomics-technologie toepasbaar weten te maken op maar een heel klein stukje tumorweefsel van patienten. Dit maakt verdere ontwikkeling van deze technologie voor de klinische praktijk mogelijk. Ik ben er van overtuigd dat (fosfo)proteomics een belangrijke bijdrage zal leveren aan het realiseren van therapieselectie voor individuele patienten.
De samenwerking met het OncoProteomicsLab is inspirerend, snel en biedt mede door de inbedding binnen de afdeling medische oncologie veel mogelijkheden voor translationeel onderzoek. De onderzoeksfocus binnen het OPL-lab naar het toepassen van fosfoproteomics voor personalized medicine is uniek in Nederland. Connie Jimenez weet mede dankzij state-of-the-art apparatuur de snelle ontwikkelingen binnen dit onderzoeksveld bij te houden en neemt hierin ook internationaal een voortrekkende positie in.
Prof. Tanja de Gruijl, Dept. Medical Oncology, new collaborator:
“The immunotherapy lab, in a VUmc/AMC Alliance collaborative project with the lab of Prof. Theo Geijtenbeek, is studying ways in which to optimally leverage autophagy in melanoma, in order to boost T cell immunity in vivo. Together with the Proteomics lab we hope to asess the protein content of differentially generated autophagosomes for their immunogenic potential, both in terms of (neo-)epitopes and immune stimulatory signals.
In addition, in our search for predictive immune biomarker profiles in patients treated with immunotherapies, targeted therapies and even more conventional chemo- or radiotherapies, we hope in future to translate systemic phenotypic immune effector cell subset signatures to (phospho)proteomic signatures, building on the technical know-how and unique expertise of Dr Jiménez and her lab."
Quotes from non-CCA VUmc collaborators
Dr. Charlotte Teunissen, Dept. Clinical Chemistry, collaborator since 2005:
“Het OPL heeft een grondige en zeer betrouwbare workflow opgezet voor liquor proteomics. Hiermee hebben we verschillende studies kunnen doen, waardoor we inzicht gekregen hebben in het liquor proteome, en nieuwe kandidaat biomarkers ontdekt hebben. Hierdoor hebben we zowel diagnostische en mechanistisch/pathologische vervolgstudies kunnen uitvoeren.”
Prof. dr. Jolanda van der Velden, Dept. Physiology, collaborator since 2015:
Prof. Jolanda van der Velden, Dr. Diederik Kuster and Maike Schuldt study determinants of disease progression in genetic cardiac disease within a reserach consortium, which is funded by the Netherlnads Heart Foundation (CVON-DOSIS):
The proteomics facility of the OPL is key in identifying cellular pathways that are centrally involved in disease progression in hypertrophic cardiomyopathy. Proteomics analysis has been performed in cardiac tissue samples from 60 genotyped and clinically well-characterized patients. We expect to report our results in a joint publication in 2018. The identified disease modifiers will be tested in functional assays to establish their exact role in cardiac disease.
Quotes from external collaborators
Prof. Gerrit Meijer, Dr. Remond Fijneman, NKI, collaborator since 2006:
“10 years of OPL = 10 years of collaborative and successful CRC research: congratulations! The OPL turned in-depth protein profiling of colorectal tumors into a reality, which added a new dimension to our research. Major achievements: The collaborative research with OPL has yielded many protein biomarkers, and has boosted research for early detection of CRC. Near future work: The OPL enables antibody-independent validation of protein biomarkers, thereby bridging the gap between biomarker discovery and assay development for clinical applications. The pleasant atmosphere around the OPL offers an inviting environment for Master students, PhD students, and postdocs to learn what proteomics is about.”
Prof. Onno Kranenburg, UMCU, collaborator since 2007:
“The Kranenburg research group aims to devise novel therapeutic strategies aiming to prevent and effectively treat metastasis in CRC, in part by targeting cancer stem cells. The OPL has been instrumental in elucidating drug resistance mechanisms in CRC stem cells, which has resulted in the publication of 6 co-authored papers in high-impact journals in the cancer and proteomics domains. We have recently further identified novel targets for therapy that drive tumor growth and metastasis in the most aggressive (mesenchymal/stem-like) CRC subtype. In addition, we have developed a diagnostic tool allowing us to select such patients for targeted therapy. We hope to renew our collaborations with the OPL in ‘proof-of-concept’ clinical and organoid-based studies as (phospho-)proteomics-based evaluation of drug response will be an essential part of future trial design.”
Prof. Jos Jonkers, NKI, collaborator since 2007:
“The focus of our group is on the genetic dissection of human breast cancer through the use of advanced mouse models. In the past 9 years, our collaboration with the OPL has given us insight into the proteome of our genetically engineered mouse model for BRCA1- and BRCA2- associated hereditary breast cancer. The results of this fruitful collaboration have been published in 2 papers in the nr 1 proteomics paper in the field, Molecular and Cellular Proteomics and a joint KWF project. Currently we are using phosphoproteomics on our patient-derived xenograft models for homologous recombination repair deficient breast cancer. First pilot results have been very promising and I look forward to the results of this continuing joint discovery.”
Prof. Jan Paul Medema, AMC, collaborator since 2014:
“One of LEXOR’s research lines focusses on colorectal cancer prognosis and response to therapy. We identified biologically subgroups with highly distinctive gene expression patterns and clinical features, which includes a subtype with dismal prognosis. In collaboration with the OPL we are currently unravelling the proteome complement of these CRC transcriptome-based subtypes. We obtained promising, in-depth proteome data of the AMC colon tumors that may pave the way to novel immunohistochemical test. Together with also ErasmusMC, UMCU and RadboudMC, we obtained funding from KWF/ Alpe d’Huzes that will enable us to expand the CRC proteome dataset and to translate these findings into a clinically applicable test.”
Prof. Jacco van Rheenen, Dept. Cancer Biophysics, Hubrecht Institute, collaborator since 2015:
“Our lab is a world-leader in the high resolution in vivo imaging of the behavior of cells in living mice. Last year, using in vivo imaging, we have shown how malignant tumor cells can phenocopy their behavior to more benign cells through extracellular vesicles (Zomer et al, Cell 2015). In collaboration with the OPL we are now tackling the molecular mechanisms behind this phenomenon. Together with the OPL, we are now identifying the protein content that is responsible for the metastatic behavior that is phenocopied. This may lead to the identification of new drug targets for tumor growth and metastasis.
We prepared our own samples at the OPL and we received excellent help with hands-on lab work and protocols optimized by the OPL. With the experience in data analysis of the OPL, we are sure we can get the best out of our data.”
Quotes from the NL proteomics veld:
Prof. Rainer Bischoff (head of the Analytical Biochemistry Group at RUG and main participant in the Biomarker Development Center): “Digitalizing cancer proteomes will help to assess the individuality and heterogeneity of cancers in view of personalized cancer treatment’’.
Dr. Arzu Umar (assistant professor and breast cancer proteome expert at EMC): “Dr. Jimenez is the founding mother of the proteomics community in the Netherlands with an enormous network in the proteomics field, both national and international, she is an expert in cancer proteomics, and has always been at the forefront of new developments and initiatives with the aim of translating state-of-the-art technologies and findings towards the clinic”.
