For this reason they are called “archive tissues”. Such tissues can be a very important resource for molecular analysis in the research and clinical practice. The reason for this is that in many cases the only tissue available for molecular clinical analysis in a patient is a small fixed and paraffin-embedded biopsy tissue. Medicine has been improving the possibility to personalize diagnosis and treatment through the research and application of molecular biomarkers. The use of archive tissues will enhance the amenability of tissues for research and clinical practice because of their availability in any hospital. The coordination action “Archive tissues: improving molecular medicine research and clinical practice – IMPACTS” involves 20 participants in 11 countries. Among them are the major experts in molecular analysis in archive tissues and those that first developed these methods. The group has validated and standardized these molecular methods, in DNA and RNA analysis, and specific guidelines have been prepared and discussed for clinical application. This step is extremely important to be able to diffuse the methods at the European level for a clinical application. The group has also studied innovative techniques such as new fixatives that are preserving macromolecules, e.g. proteins, in the same way as in fresh frozen tissues. The introduction of proteomics research and clinical application is also one of the priorities, with the development of two strategies. The first one is a new method that allows protein analysis in formalin-fixed tissues (most of the tissues today are formalin-fixed). The second one is the use the new fixatives in order to obtain a perfect preservation of proteins. These developments will make it possible to perform molecular analysis at the DNA, RNA and protein level, directly in those tissues in which the clinical diagnosis was defined, even in a tiny biopsy, with a careful selection of the cells of interest. The group has also prepared multicentric studies in human archive tissues, especially for the validation and standardization of molecular analysis and to develop methods for the guidelines. The activity was also related to the preparation of tissue bio-banking rules specific for archive tissues, for which specific guidelines are necessary also in archive tissues. A new project to define a network of archive tissue virtual banking among the participants in the project was developed. This network was included in the European Biobanking Infrastructure (BBMRI). At the end of the project, in order to continue the activity of IMPACTS, a Pan-European Archive Tissue Biobanking Network was begun, starting from the already existing IMPACTS network. This network is being developed in collaboration with the European Society of Pathology (ESP) and the European Biobanking Infrastructure (BBMRI). From the second year of activity bioethics issues were discussed to prepare specific approaches in the use of archive human tissues for clinical research. An international meeting on bioethics in the translational research use of archive tissues was organized with the participation of the IMPACTS groups and the experts of the European Infrastructure (BBMRI). This has given the bases for the specific management of the archive tissue biobanks in Europe. The project was supposed to last two years, but a 12-month elongation was granted, until February 2010, to allow the participants to better fulfil their final goals, to improve and accelerate molecular medicine research and clinical practice using archive tissues. 4 Section 1 – Project objectives and major achievements during the reporting period Overview of general project objectives The translation of molecular biology knowledge to a clinically applied molecular medicine is a very slow process as pointed out by many international organizations (see IMI in Europe and FDA in the US). The project “Archive Tissues: Improving Molecular Medicine Research and Clinical Practice – IMPACTS”, is devoted to accelerate this process by promoting the use of archive tissues as biological material for the clinical application of molecular analysis in medicine. These archive tissues are the human tissues taken from the human body for diagnostic or surgical therapy reasons. All these tissues are fixed and then paraffin-embedded to be able to cut few sections for the definitive histopathological diagnosis. Most of the tissues are then stored in the pathology archives of any hospital, sometimes for many decades. For this reason, these tissues are called “archive tissues”. It is important to point out that archive tissues are all the routinely treated tissues in any hospital in Europe and all over the world. If we are able to perform molecular analysis in these tissues, we do not have to modify any procedure at the clinical level, but we can just apply the new molecular methods. This is a crucial point because it is very difficult and demanding and it takes a very long time to try to change any clinical procedure in hospitals. The aim of the IMPACTS project is to work on the use of archive tissues at the molecular level in the clinical practice, with the development of work packages devoted to validation and standardization of the molecular methods, proteomics in archive tissues, the use of new fixatives with a high level of molecular preservation, tissue bio-banking, bioethics rules in archive tissues and diffusion of the new approaches at the European level. The project is also promoting multicentric research on methods and biomarker validation. The project started in March 2007 and its first task was to evaluate the molecular methods used in archive tissue analysis, because at present each laboratory is using different protocols. This goal was reached by comparing the techniques used by the participating laboratories and by defining the preliminary guidelines for molecular analysis in archive tissues. These guidelines are also the baseline for archive tissue technique dissemination in Europe. In the third year the guidelines were completed, edited and are going to be published by Springer Verlag in 2010. Many validation tests were performed by the laboratories of the group, with special attention to pre-analytical modification of archive tissues and method standardization. Several publications were completed or submitted. To approach the clinical use of these methods it is important to develop specific research and coordination projects. For this reason, the IMPACTS group prepared some proposals for the 7th EP: three projects proposals were presented to the first LHS call, two proposals to the second LHS call, four proposals to the third LHS call and one proposal to the fourth LHS call (see results and comments in the specific objectives and WP description). Moreover, the IMPACTS group submitted a project proposal for the 7th and 8th COST collection date (see results and comments in the specific objectives and WP description). To work on a multicentric project on human tissues it is absolutely necessary to establish and follow general bioethics rules. One of the groups’ goals was the preparation of some bioethics guidelines at the European level for research use of archive tissues. This WP was outlined in the IMPACTS meeting in Munich in February 2008 and started in the second year of activity. It was managed by the Pisa group and was developed mostly in the third year. In January 2010 a dedicated meeting was 5 organized in Pisa, with the participation of many European experts in the legal and scientific aspects of the bioethics issue. Any project for validation of methods or clinical biomarkers is related to the amenability of a large number of human tissues, for this reason one of the goals of the coordination action is also to develop guidelines and projects for tissue bio-banking. This activity was supposed to be developed in the second year of activity, but a preliminary organization for tissue bio-banking had already been prepared at the beginning of the action, as a basis for another European project called “Biobanking Network – Molecular Medicine Evidence groups”. This activity was developed together with the European Infrastructure for Biobanking (Biobanking and Biomolecular Resources Research Infrastructure – BBMRI) and it was presented in the proposals submitted for the 1st call of the 3rd FP7. The activity of biobanking was further developed after the second year of activity and the organization of a Pan-European Archive Tissue Biobanking Network was prepared, starting from the IMPACTS groups and with the collaboration of the European Infrastructures BBMRI and the European Society of Pathology (ESP). Specific attention was given to technology innovation. The participants studied in their laboratories the possibility to use new fixatives that preserve a high level of molecular integrity for nucleic acids and proteins. Some approaches were also done with groups of nanobiotechnology to define new methods of protein separation and new types of arrays. Throughout the project, the participants continued to study at the multicentric level the results obtained with the use of new fixatives that preserve a high level of molecular integrity for nucleic acids and proteins. This study was also related to the proposals at the European level to ban formaldehyde from the environment because of the dangerous consequences on health. The groups also tested new techniques about high throughput imaging in archive tissues using nanotechnology approaches. A specific group within the IMPACTS project dealt with the possible approaches of archive tissue techniques to proteomics methods. In this field two research lines were developed. The first one was dedicated to protein extraction from formalin-fixed and paraffin-embedded tissues, for which the Munich group developed a commercial kit that was multicentrically validated. The second line of proteomics research is related to new alcoholic fixatives, that perfectly maintain proteins. The Munich group also prepared a European course about proteomics in archive tissues and continued to organize multicentric validation studies that are going to be developed also after the end of the project. A website of the group was prepared (www.impactsnetwork.eu) and constantly updated and enriched with information about the BN-MEM (Biobanking Network: Molecular Evidence Medicine group) project, the scientific production of the groups and the reports of the IMPACTS meetings. Summarise the objectives, work performed, contractors involved and the main achievements In the three years of activity, the following objectives of the IMPACTS coordination action were fulfilled: a)To analyze the present knowledge and use about molecular analysis in archive human tissues in Europe and to propose method validation and standardization: after comparing the molecular protocols used for the analysis of DNA and RNA in archive tissues (the results of this comparison were discussed in specific meetings held in Istanbul in September 2007 and especially in Munich in February 2008), the laboratories participating in the project validated the protocols used for DNA 6 and RNA extraction in FFPE tissues. The results of this validation were discussed in the Dubrovnik and Porto meetings. The further results of the validation performed during the third year were discussed during the final IMPACTS meeting. To make the connection among the different institutions more effective, the coordinator visited many of the laboratories throughout the project period. In the first Munich meeting the preliminary guidelines for molecular analysis in archive tissues were presented, to be discussed and improved. Those guidelines for were further developed in the Dubrovnik and Porto meetings and their preparation was concluded at the end of the third year of activity. All the laboratories produced papers published in international peer review journals throughout the project period (the whole list of publications is reported in the IMPACTS website). The scientists involved in the IMPACTS project participated in many meetings and congresses related to the aims of the project. b)Dissemination in European laboratories of validated and standardized methods with good practice rules: the guidelines for molecular methods in archive tissues prepared by the participants are the baseline for the dissemination of these methods in Europe. Moreover, a website (www.impactsnetwork.eu) was prepared and constantly updated and enriched, to give information on the project and to diffuse methods and initiatives in the field. Dissemination is also performed by the organization of meetings within the ESP. The first one took place during the ESP congress in Istanbul in September 2007 and the other IMPACTS symposiums were organized within the ESP meetings in Barcelona (May 2008) and Florence (September 2009). During those meetings the technological approaches to archive tissues were presented to the European pathologists in a specific session. An IMPACTS technical meeting was held in June 2008 in Dubrovnik, in correlation with the Adriatic Society of Pathology (ASP) meeting. Moreover, a European Molecular Pathology course was organized in Graz in April 2009 and a European Protein Analysis workshop was organized in Munich in March 2009. c)To point out future perspectives of functional genomics and proteomics at the research and clinical level: during the IMPACTS activity, the participants in the project submitted several proposals to the 7th EP, to develop research in the field of molecular analysis in archive tissues. The proposals are listed here as follows: 1. “Bio-banking Network – Molecular Evidence Medicine groups (BN-MEM)”: this project was presented to develop a very large tissue banking system in 18 different European areas, by using the virtual collection of the pathology archives of 128 hospitals and the collection of surgical left-over treated with new fixatives. The proposal received a positive evaluation, but didn’t reach the threshold to be financed. 2. “Tapping the untranslated potential of the human transcriptome in colorectal cancer archive tissues (UNTAP)”: this project was proposed to study untranslated RNAs, in large case studies of archive tissues. The project was rejected. 3. “A new fixative offers revolutionary opportunities for cancer biomarkers research (FORCaRe)”: this proposal was presented as an SME project by Milestone S.r.l., one of the IMPACTS participants, to develop research about a new fixative that allows preserving proteins just like in fresh frozen tissues. The proposal was rejected. 4. “International Meeting on Archive Tissues: a shortcut for biomarker validation and biomedicine clinical application (ATMEET)”: this proposal was submitted as a support action to prepare a world congress about archive tissues to compare the European work with the experiences done in archive tissues by other research centres in the world. The proposal had a positive evaluation but did not rank for financing. For this reason it was resubmitted for the 3rd FP7 call, unfortunately without success. 7 5. “European Project on Improvement and Standardisation of Pre-Analytical Procedures for Modern Pathology (EURO-IS4PATH)”: this proposal was developed to study the pre-analytical procedure of tissue treatment to standardize such techniques to a high level of macromolecule preservation. The proposal had a positive evaluation, but did not rank for financing. 6. “Systems Integration of DNA SEquence changes with RNA and protein QUantitative Alterations in Large archival case studies (SISEQUAL)”: this proposal was submitted for the 3rd FP7 call. It is related to the large International Cancer Genomic Consortium project, in which high numbers of tumour tissues are sequenced. The aim of this project is to compare results of very large archive tissues case studies at mRNA and protein level. The proposal had a positive evaluation, but did not rank for financing. 7. “Molecular Omics technologies Validation and standardization In large-scale fixed and Embedded clinical Samples (MOVIES)”: this proposal was submitted for the 3rd FP7 call. It is related to the use of the very large collection of archive tissues as biobanking resource, with the validation and standardization of high throughput molecular methods. The proposal had a positive evaluation, but did not rank for financing. 8. Protein Technologies for Clinical Tissues (PROTECT): this proposal was submitted for the 3rd FP7 call by the Technologische Universität of Munich (TUM). It is related to the validation and standardization of protein analysis in FFPE tissues and new fixatives treated tissues. The proposal had a positive evaluation, but did not rank for financing. 9. “Molecular Workflow for the Effective Detection of Multiplex HPV Markers in Cervical Cancer Patients (CERVIFLEX)”: this proposal was a two-step one and was submitted for the 4th FP7 call. The proponents of this project aim at developing and implementing a new molecular diagnostic workflow performing a multiplex analysis of HPV biomarkers at the DNA, RNA and protein level directly in clinical samples from patients with pre-malignant and neoplastic cervical lesions. Unfortunately this proposal did not pass the first-step evaluation, despite the importance of the issue and the good potentialities this project could offer in the clinical practice. For this reason, the IMPACTS group decided to use the redress procedure in order to have it re-evaluated. Moreover, the IMPACTS group submitted a proposal for the 7th collection date (oc-2009-2) of the European Cooperation in the field of Scientific and Technical Research (COST). The proposal is: “European Network for Archive Tissue Analysis and Clinical Application (EN-ATACA)”: it is a two-step proposal and it’s aimed to disseminate the knowledge acquired during the IMPACTS project worldwide. This project was rejected at the first-step evaluation due to its overlapping with the aims of the IMPACTS project. For this reason, since the IMPACTS project ended on 28th February 2010, the participants decided to resubmit this proposal (named EN-ATACA2) for the 8th collection date (oc2010-1), unfortunately without success despite the great chance this project could have given to the IMPACTS group to disseminate all over Europe and even outside the important results reached so far. By presenting all these proposals, the IMPACTS group tried to develop a basic system of “Reverse Translational Research” in Europe, starting from clinical material. This could be the first large group of European scientists working on archive tissues in the different pathology fields. The IMPACTS participants were very surprised to see all those proposals rejected by the evaluators, as this new approach could offer great opportunities to Europe to be in the forefront of international research. Moreover some of the most experienced European pathologists were involved in those issues. A better understanding and openness to such new techniques could really help European research to be competitive worldwide. Therefore we really think that the European scientific evaluation system needs some adjustments. 8 The coordinator of the IMPACTS project was also invited to participate in one of the major international research projects on cancer, the “International Cancer Genomics Consortium – ICGC”, that was proposed by the major international organizations, like the European Commission, NCI, Genome Project, Sanger Institute etc. The project aims at sequencing a high number of major cancers. The scientists of the coordination action developed new methods to study molecular markers with the proteomics techniques. Karl Becker of the Technological University of Munich developed a method to extract proteins directly from formalin-fixed and paraffin-embedded tissues. This allows having a more precise quantification of proteins in archive tissues, which can help clinical prognostic and therapeutic decision. Moreover, the groups of Trieste and Torino showed that with new alcoholic fixatives it is possible to study proteins just like in fresh-frozen tissues. A specific group was appointed within the IMPACTS coordination action to study biomarkers at the proteomics level. The validation of this method was carried on by the IMPACTS groups through multicentric studies. A multicentric effort was also performed to study the preservation and the analysis of proteins in tissues fixed with new types of alcoholic fixatives. A specific meeting was organized in Munich in August 2008. A course on the proteomics techniques in archive tissues was organized by TUM in Munich in March 2009. d)To establish bioethical guidelines for the correct use of human archive tissues in research and clinical practice: the bioethics activity started officially in the second year, although its organization was decided during the Munich meeting in February 2008. The Pisa group was in charge of the development of this issue, with the hiring of an expert in law. The topic was broadly discussed together with well-known European bioethics experts in a dedicated meeting which took place in Pisa in January 2010. The objective is to create European bioethics guidelines for research use of archive tissues. In the first year, a European project called ACUME2 was contacted. This project is dedicated to life sciences-humanities comparison and a specific activity about bioethics in the use of human tissues in molecular research was developed. Our cooperation with ACUME2 went on throughout the project. e)To explore the possibilities to organize archive tissue banks for future research: this activity started officially in May 2008, but the first steps for its development had already been taken in the preparation and organization of the BN-MEM proposal presented for the 1st call of the 7th EP. This bio-banking project is related to the collection of archive tissues stored in the pathology departments of 128 European hospitals in 18 European areas. The biobanking initiative of the IMPACTS groups was developed in the context of the European Infrastructure BBMRI and the coordinator of the IMPACTS groups was asked to participate as an expert of disease biobanks in the Work Package 3 of the BBMRI project. Since one of the most important goals of IMPACTS is the development of archive tissue biobanking systems, the participants decided to develop a Pan-European Archive Tissue Biobanking Network starting from the IMPACTS network, with the collaboration of BBMRI and the ESP. The network will be enlarged to all the European countries. f)To promote technology innovation in archive tissue molecular analysis in collaboration with biotechnology industries: one of the participants in the coordination action is an SME (Milestone S.r.l.) which has the patent for a new fixative that preserves proteins well, the same as in freshfrozen tissues, and maintains a high level preservation also for DNA and RNA. Many participants tested this new fixative by comparing it among laboratories. Validation and standardization projects were multicentrically developed. Milestone prepared a series of prototypes for vacuum treatment of 9 fresh tissues and to obtain precise fixation time. These issues were further discussed during the final IMPACTS meeting in Munich. Section 2 – Workpackage progress of the period WP1: Management of the Action Deliverables: D1.1-Consortium management: the consortium management started with the project in March 2007 and in particular with the organization and development of the Kick-off Meeting, the definition of the Steering Committee, the preparation of the Consortium Agreement and the general meeting in Munich held in February 2008. The activity was continuous and went on in the second year with the organization of the IMPACTS technical meeting in Dubrovnik, of the 4th IMPACTS meeting in Porto, with the gathering of the Steering Committee in Vienna and of the PMB in Porto. In the third year the consortium management was carried out with the organization of the IMPACTS session in the ESP meeting in Florence, of Bioethics in Pisa and with the final and PMB meeting in Munich. D1.2-Administrative management: the administrative management started in the first year and was continuously carried out throughout the project by our administrative officer, who managed all the project expenses, kept in touch with the administrative officers of each participating group and, at the end of each reporting period, prepared the Management Report, collecting information from all the participants. Milestones and expected results: M1.1- Control of WP results: the control of WP results was done by the coordinator at due time. The coordinator urged the groups that were late with their work in sending information about protocols, activity and other material for comparison and discussion. The coordinator also visited some of the participating institutions and developed some direct or e-mail discussions to solve some problems and to manage the research developments. M1.2- Diffusion of the WP results: a final diffusion is already being performed with the forthcoming publication of the European guidelines, with the organization of the meetings, especially those in connection with scientific societies, and with the organization of technical courses, as well as with the preparation and updating of the IMPACTS website.

D3.2-Diffusion of guidelines: the final version of the guidelines was edited and will be published by Springer Verlag in 2010. Milestones and expected results M3.1-Standardized protocols guidelines diffusion: the final version of the guidelines was edited and will be published by Springer Verlag in 2010. M3.2- European meetings organization together with ESP: three symposia within the ESP meetings were organized: a. Short IMPACTS meeting in Istanbul during the 21st ESP-European Congress of Pathology in Istanbul from 8th to 13th September 2007. b. IMPACTS symposium in the ESP meeting in Barcelona from 19th to 22nd May 2008. c. IMPACTS symposium in the ESP meeting in Florence from 5th to 9th September 2009. Moreover, two sessions of the IMPACTS group are going to be prepared for the ESP Congress in Krakow in September 2010. 12 WP4: Technology innovation New fixation procedures were recently developed to shorten the time of histopathology diagnoses, these methods have shown also a major improvement in nucleic acids and protein preservation. The objective is to test the possibility for these new procedures to be used as routine treatment of tissues in hospital pathology departments and to test the opportunities of better molecular analyses at DNA and RNA level Deliverables D4.1 - Proposal of new fixation procedures with better molecular preservation: the study of new fixatives started from the beginning of the project and many participating laboratories tested different fixatives. Peer-review publications were prepared. Milestones and expected results M4.1 - Validation of new fixation procedures with better molecular preservation: a validation study of new fixatives was proposed in the Munich meeting in February 2008. Molecular preservation standards in new fixatives were tested by many laboratories on new fixative treated tissues. WP5: Archive tissue bioethics There are no common bioethics rules in the European countries for research use of human tissues and this is complicated by the “subsidiarity principle”. It was decided in Munich in 2008 that the activity would start with the collaboration of experts defined by each participating institution to discuss and evaluate the possibility of a common frame of bioethics rules necessary for the multicentric studies. Transdisciplinary collaboration should ensure to obtain results consistent with research opportunities but also with social concerns. In the first year of activity a European project called ACUME2 was contacted. This project is dedicated to life sciences-humanities comparison and some specific activities about bioethics in the use of human tissues in molecular research were developed in association with IMPACTS. The cooperation with this project went on throughout the project. To this regard, a brainstorming meeting about “Bioethics and Biobanks” was organized in Bologna on 23rd and 24th May 2009 by ACUME2. In the last year, a specific activity about bioethics was organized by the Pisa group with a final meeting held in Pisa in January 2010, with the participation of international experts. Deliverables D5.1- Diffusion of proposal of common bioethics guidelines for human tissues multicentric research: guidelines for multicentric studies in Europe on archive tissues were prepared by the Pisa group with the collaboration of the Trieste group. A summary of the bioethics guidelines will be published in a peer-review journal. Milestones and expected results M5.1-Proposal of bioethics guidelines for human tissues multicentric research: the guidelines for bioethics in archive tissues will be disseminated by the participating groups and they will be diffused among pathologists and other researchers interested in molecular analysis in archive tissues. WP6: Human tissue archives A very large number of tissues specimens with any kind of diseases are stored in the pathology archives of any European hospital. This is very valuable material for molecular research in human pathology. All these tissues represent an already existing tissues bank for molecular studies in AT. 13 Possible management of this material among the hospital institutions that participate in the proposal is a specific objective of the Action. Although this activity was supposed to start officially in May 2008, the first steps for its development were taken in the first year, with the preparation and organization of the BN-MEM proposal presented to the 7th EP. In the treatment of the surgical origin large specimens, adjunctive tissue fragments can be easily collected. New fixation procedures allow a very good preservation of nucleic acids and proteins, similar to that of fresh frozen tissues (WP4 and 7). The aim is to study the possibility of a multicentric collection of tissues that can be constituted by the anonymous collection of well documented specimens for large European research studies as already proposed in the BN-MEM. In this way, it will be possible to compare formalin-fixed tissues with frozen tissues and new fixative treated tissues. This new procedure will also consider fast processing of tissues using microwave techniques. In the final meeting in Munich the IMPACTS group decided to develop a pan-European network of archive tissue biobanking. This network will start from the already prepared BN-MEM and then diffused to other European pathologists, with the purpose to develop a very extensive network throughout Europe. This network will be on voluntary and collaborative basis. The different institutions will refer to hubs specialized in molecular analysis in this kind of tissues, that will respect specific standardized methods and high level controls. The diffusion of the network throughout Europe will be started during the next ESP meeting that will be held in Krakow in September 2010. Deliverables D6.1- Proposal of guidelines for multi-hospital archive tissues collections for European multicentric projects: bio-banking guidelines for archive tissues were discussed in the Dubrovnik and Porto meetings. They were further defined in the Florence, Pisa and Munich meetings and will be further developed in the Krakow ESP meeting. D6.2- Proposal of multicentric collection of tissues treated with new fixatives with nucleic acids and protein preservation: the use of new fixatives was tested in many tissue samples by several participating laboratories and their use was in the projects presented in the 3rd call of the 7th FP project. In the final meeting in Munich in February 2010 it was decided to start the Pan-European Network of Archive Tissue Biobanks. This initiative will be further developed in the ESP meeting in Krakow in September 2010. Milestones and expected results M6.1- Guidelines for archive tissue multicentric collection: bio-banking guidelines for archive tissues were discussed in the Dubrovnik and Porto meetings and finalized in Pisa and Munich in 2010. The issue was also developed in the context of the European Infrastructure devoted to biobanking (BBMRI). WP7: Proteomics in archive tissues There is a need for better protein analysis tools in archive tissues. This WP aims to evaluate novel protein extraction technologies developed by European researchers and to explore new fixation procedures compatible with subsequent protein analysis. The influence of histological procedures on protein yield from archive tissues was not known before. We started our work showing that histological techniques influence the efficiency of protein recovery from archival tissues. A suggestion, therefore, was made by the IMPACTS members that protein extraction for downstream analysis should be performed using unstained tissue sections. In addition, it was evaluated whether proteins could be extracted from very small pieces of tissues, such as punch biopsies. Indeed, it was shown that high quality protein samples could be obtained from punch biopsies of archival tissues. Furthermore, transcription factors which are usually present 14 in minute amounts in archive tissues, such as the E-cadherin repressor Snail, could be quantitatively analyzed. As the project went on, we were able to demonstrate that clinically relevant proteins, such as estrogen receptor, HER2 and EGFR can be extracted from formalin-fixed tissues as well as from tissues fixed with novel fixatives and analyzed by Western blot and protein lysate microarray technology. These results were reported at the IMPACTS meeting in Porto. Moreover, five members of the IMPACTS consortium focused on the evaluation of protein analysis in tissues fixed with formalin and FineFix, a new fixative. Tissue samples were fixed in parallel with formalin (FFPE) and FineFix and inspected histologically. Five sections from three matched samples of each tissue specimen (lung, colon, breast) were distributed within the consortium to evaluate efficiency of protein recovery. Selected marker proteins were compared between the two fixation procedures using protein lysate microarray technology. An optimized protocol allows proteins to be extracted successfully from FFPE and FineFix tissues, even when processed in different European laboratories. Further, we found remarkable differences for two large membrane proteins, EGFR and HER2. Signal intensities for EGFR (P=0.007) and HER2 (P=0.02) were significantly higher in the FineFix samples compared to the FFPE samples, whereas no differences were observed for β-Actin, E-cadherin, and ER. Although long-term studies for formalin substitutes such as FineFix are still lacking, formalin-free tissue fixation represents a reliable alternative to FFPE fixation for protein preservation as far as quality and quantity are concerned. These results were reported at the European Congress of Pathology, Florence, 2009. In addition, a manuscript with the data was prepared and submitted for publication. There was a delay in the deliverables and milestones. The reasons for the delays included problems with the spotting device and delays in collecting and shipping tissue samples. However, the results are complete now. Protein expression in archive tissues can be studied by IHC and tissue arrays, but also by protein extraction as shown recently by European scientists involved in the action, directly from formalinfixed tissues. These techniques are very important to be used for translational research proteomics analysis also in AT: at the Technological University of Munich a method to extract proteins directly from formalin-fixed and paraffin-embedded tissues was developed. This allows having a more precise quantification of proteins in archive tissues, which can help clinical prognostic and therapeutic decision. Multicentric validation tests have been performed and the results are going to be published. Recently new rapid fixation procedures that can allow to prepare a final histological slide in a short time have been developed. These methods have shown that DNA, RNA and proteins are preserved as in fresh frozen tissues. The objective is to explore the technical availability and reproducibility of these new methods for possible research and clinical applications of protein analysis: new fixatives allow maintaining a higher level of preservation of proteins; in particular FineFix, patented and produced by Milestone S.r.l., has very good results, comparable to those obtained in fresh tissues. A specific group of five laboratories tested these and other new fixatives to obtain the best conditions for proteomics analysis in archive tissues. Many participating laboratories developed experience in the field and the results are going to be published. Deliverables D7.1-Proposal of proteomics protocols in formalin-fixed archive tissues: the protocol for the analysis of proteins in formalin-fixed and paraffin-embedded tissues was tested in a multicentric study by five participating laboratories, and specific protocols were prepared. 15 D7.2-Proposal of proteomics protocols in new fixatives treated tissues: the new alcoholic fixatives were multicentrically tested to establish the molecular preservation and the morphology level in the tissues. Papers are in preparation. Milestones and expected results M7.1-Proteomic analysis protocols in archive tissues for research and clinical applications: protocols for analysis of biomarkers at the proteomics level have already been tested and future experiences are going to be developed by the participating laboratories, to define validated and standardized protocols. 16 Table 1: Deliverables List Del. no.
