In November 2011, KHCCBIO was established at the King Hussein Cancer Center (KHCC) with the support of Seventh Framework Programme (FP7) funding from the European Union (khccbio.khcc.jo). KHCCBIO was developed for the purpose of achieving an ISO accredited cancer biobank through the collection, processing, and preservation of high-quality, clinically annotated biospecimens from consenting cancer patients, making it the first cancer biobank of its kind in Jordan. The establishment of a state-of-the-art, standardized biospecimen repository of matched normal and lung tumor tissue, in addition to blood components such as serum, plasma, and white blood cells, was achieved through the support and experience of its European partners, Trinity College Dublin, Biostór Ireland, and accelopment AG. To date, KHCCBIO along with its partners, have worked closely in establishing an ISO Quality Management System (QMS) under which the biobank will operate. A Quality Policy Manual, Validation, and Training plan have been developed in addition to the development of standard operating procedures (SOPs) for consenting policies on ethical issues, data privacy, confidentiality, and biobanking bylaws. SOPs have also been drafted according to best international practices and implemented for the donation, procurement, processing, testing, preservation, storage, and distribution of tissues and blood samples from lung cancer patients, which will form the basis for the procurement of other cancer types. KHCCBIO will be the first ISO accredited cancer biobank from a diverse ethnic Middle Eastern and North African population.

However, the success of molecular and cellular analysis in both clinical and translational research is strongly dependent on the collection, handling, storage, and quality control of fresh human tissue samples. The aim of this study was to evaluate an innovative vacuum-based refrigerated system, as a logistically feasible technology to increase the collection of tissue specimens, preserving the integrity of cellular and molecular components. We tested randomly-selected tissues stored under vacuum at 4°C by using endpoints important for research and diagnosis, including tissue morphology, epitope stability, and RNA integrity. Gene expression was evaluated by qualitative and quantitative RT analysis of selected housekeeping and tissue-specific genes. Tissue morphology and overall protein stability were generally well preserved, being compromised only in gallbladder tissue. By contrast, phosphoprotein and RNA analysis demonstrated a time-dependent degree of degradation, with progressive loss of stability from 24 to 72 hours. However, this reduction in RNA quality did not represent a limitation for successful expression analysis of selected genes. Indeed, a comparative qualitative and quantitative RT-PCR analysis showed that RNA extracted from tissues stored under vacuum is suitable for gene expression profiling, but requires highly sensitive technologies, such as quantitative RT-PCR. These data suggest that the refrigerated vacuum-based system represents a suitable and feasible technology for routine transport of fresh specimens from surgery to biobanks, thus increasing the opportunity to collect biospecimens. </p>","PeriodicalId":49231,"journal":{"name":"Biopreservation and Biobanking","volume":"12 1","pages":"35-45"},"PeriodicalIF":1.6,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/bio.2013.0065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40302963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Storage conditions, such as temperature and the length of time that tissues and purified RNA stay frozen, may directly impact RNA preservation. In this study, we evaluated a) the quality of RNA (as measured by RNA Integrity Number) purified from head and neck tumor tissues stored at -140°C for distinct time intervals of up to 7 years, and b) the quality of their respective RNAs stored for 4 years at -80°C when diluted at either 250 ng/μL or 25 ng/μL, with repeated freezing and thawing. Additionally, we generated a profile of the RNA collection of human tumors from different body sites stored at the AC Camargo Biobank. Our results showed no significant change in RIN values according to length of storage at -140°C. With respect to RNA aliquots stored at -80°C, RNA integrity at 250 ng/μL was preserved, while statistically significant degradation was observed at 25 ng/μL after only 8 months of storage. The RNA collection from most of the human tumors stored at the AC Camargo Biobank exhibited high quality, with average RIN around seven. However, ovary and stomach samples had the greatest RNA degradation. Taken together, the results show that both the temperature of preservation and the concentration of RNA should be strictly controlled by the biobank staff involved in macromolecule purification. Moreover, the RNAs from our biobank can be useful for the most demanding methods of gene expression analysis by virtue of adherence to optimal standard operating procedures for both tissue and macromolecule laboratories. </p>","PeriodicalId":49231,"journal":{"name":"Biopreservation and Biobanking","volume":"12 1","pages":"46-52"},"PeriodicalIF":1.6,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/bio.2013.0056","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40300292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Swedish Cervical Cytology Biobank (SCCB) was designed as a hospital-integrated biobank in 2011. The SCCB has now been implemented in 10 county councils scattered across the country. It is headquartered at Karolinska University Hospital in Stockholm. The SCCB now processes more than 60% of the liquid-based gynecological cell samples obtained throughout Sweden. To improve the productivity of health care and research that rely on SCCB samples, a high level validation of the biobank system according to the principles of Good Laboratory Practices (GLP) is required. The performance of an entire high-throughput system validated by measuring the cell yield proved unsatisfactory after 1 year of sample collection and aliquoting. However, the results led to a number of high quality technical interventions for workflow enhancement. Subsequently, the improved process was applied to the system and led to a significant increase in cell yield. After the integration of the improved high quality methodology into the SCCB, the biobank services progressed more rapidly to serve the needs of personalized medicine and clinical studies. This enhancement was mainly due to the increased ability of the biobank to provide samples to research groups without any risk of leaving insufficient sample volumes for the care of the donor. </p>","PeriodicalId":49231,"journal":{"name":"Biopreservation and Biobanking","volume":"12 1","pages":"69-73"},"PeriodicalIF":1.6,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/bio.2013.0068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40300295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As noted by Scott et al. referencing an Indiana University article, ‘‘biobanks exist on every continent, even Antarctica.’’ A map in this article shows that many current biobanks are centered in institutions in North America and Europe. However this landscape is quickly changing. Several meetings in the fall of 2013 highlighted the expanding global nature of biobanking, including the Annual Biobank China conference (http://www.scrcnet.org/ biobank2013/eindex.asp) and ESBB meeting in Verona Italy (http://www.esbb.org/verona/), as well as the French BIOBANQUES annual network meeting in Paris. During the ESBB meeting, planning for new biobanking networks in Israel and Africa were presented. H3Africa (http://h3africa.org/), as noted in our Biobanking in Emerging Countries Section in the December 2013 issue will have major infrastructure and ethical-regulatory challenges to overcome as it develops in the coming year. In Europe BBMRI-ERIC (Biobanking and Biomolecular Resources Research Infrastructure European Research Infrastructure Consortium, http://bbmri-eric.eu/) held its inaugural conference in Austria in September 2013. As noted on its web site BBMRI-ERIC ‘‘will increase efficacy and excellence of European biomedical research by: facilitating access to quality-defined human health/disease-relevant biological resources; including associated data in an efficient and ethically and legally compliant manner; reducing the fragmentation of the biomedical research landscape through harmonization of procedures, implementation of common standards and fostering high-level collaboration; capacity building in countries with less developed biobanking communities, thereby contributing to Europe’s cohesion policy.’’ As noted in multiple presentations at Annual Biobank China and ESBB, there are a number of recurring themes among existing and emerging biobanks and biobanking networks. In China, there are multiple efforts underway to develop new biobanks and networks. The international nature of the participants at the September meeting in Shanghai reflected the ever-expanding global nature of biobanking, as plans develop to realize the tremendous opportunities available for the growth of biospecimen resources in China. In the presentations at ESBB by Akin Abayomi concerning H3Africa, and Yehudit Cohen concerning the new national biobanking network in Israel, securing initial funding and planning for sustainability of these programs were noted as major focuses and challenges. And as always, any new biobanking effort requires close attention to infrastructure (e.g. IT systems, security, equipment validation and maintenance, quality management) and the ethical-regulatory frameworks.
