    ABSTRACT: Biorepositories have been key resources in examining genetically-linked diseases, particularly cancer. Asian Americans contribute to biorepositories at lower rates than other racial groups, but the reasons for this are unclear. We hypothesized that attitudes toward biospecimen research mediate the relationship between demographic and healthcare access factors, and willingness to donate blood for research purposes among individuals of Korean heritage. Descriptive statistics and bivariate analyses were utilized to characterize the sample with respect to demographic, psychosocial, and behavioral variables. Structural equation modeling with 5000 re-sample bootstrapping was used to assess each component of the proposed simple mediation models. Attitudes towards biospecimen research fully mediate associations between age, income, number of years lived in the United States, and having a regular physician and willingness to donate blood for the purpose of research. Participants were willing to donate blood for the purpose of research despite having neutral feelings towards biospecimen research as a whole. Participants reported higher willingness to donate blood for research purposes when they were older, had lived in the United States longer, had higher income, and had a regular doctor that they visited. Many of the significant relationships between demographic and health care access factors, attitudes towards biospecimen research, and willingness to donate blood for the purpose of research may be explained by the extent of acculturation of the participants in the United States.

    ABSTRACT: A major concern in both the laboratory-medicine and research communities is the quality of human specimens for analysis. However, there is insufficient scientific evidence regarding optimal conditions for handling and storing routine specimens, especially those in liquid form. Thus, we investigated the stability of clinically relevant samples stored under various conditions. Ten clinical laboratories in Japan conducted analyses of the stability of post-clinical (left over after analysis) test samples in relation to temperature and storage duration. We examined serum, whole blood, and urine samples submitted to each laboratory for routine testing. In this study, at least 5 samples for each of 35 tests were analyzed at each laboratory. After completion of routine testing, specimens with sufficient residual volume and values between LL-R/2 (lower limit of reference interval) and UL+R/2 (upper limit) were divided into 300 μL aliquots, where R=UL - LL. Aliquots of serum specimens were stored at either room temperature (23°C), 4°C, -20°C, or -80°C without light exposure. Aliquots of whole blood and urine specimens were stored at either 23°C or 4°C. The storage time was either 1, 3, or 7 days. Average differences between pre- and post-storage test results were evaluated for each laboratory test by two-way ANOVA. F-values for between-day variations were used for judging the statistical significance of storage-related changes in test values, whereas the ratio of between-day SD to between-individual SD (one-fourth of reference interval) was used to indicate the practical significance of the change. Sample denaturation is clearly temperature- and storage-duration dependent for almost all analytes. In general, specimens were most susceptible to denaturation at 23°C, then 4°C, -20°C, and -80°C. This study confirmed the accumulated routine, practice-based, detailed knowledge regarding specimen stability and will help to ensure the reliability of laboratory test results.

    ABSTRACT: Urine samples were collected from eleven randomly selected patients with kidney disease, including diabetic nephropathy, chronic nephritis, and nephritic syndrome. Urine samples were treated with one of four protocols for freezing and thawing: freeze directly and thaw directly; freeze directly and thaw by temperature gradient; freeze by temperature gradient and thaw directly; and freeze by temperature gradient and thaw by temperature gradient. After one to six freeze/thaw cycles at -20°C or -80°C, different biomarkers showed differential stabilities. The concentrations of total protein, calcium, and potassium did not change significantly after five freeze/thaw cycles at either -20°C or -80°C. Albumin could only sustain three freeze/thaw cycles at -20°C before it started to degrade. We recommend that urine be stored at -80°C as albumin and the organic ions could sustain five and six freeze/thaw cycles, respectively, using the simple "direct freeze and direct thaw" protocol. Furthermore, in most cases, gradient freeze/thaw cycles are not necessary for urine sample storage.

    ABSTRACT: This article is part of a series of publications providing formal method validation for biospecimen processing in the context of accreditation in laboratories and biobanks. We report the optimization and validation for fitness-for-purpose of automated and manual protocols for isolating peripheral blood mononuclear cells (PBMCs) from whole blood, and compare the two methods. The manual method was optimized for whole blood centrifugation speed, gradient type (Ficoll, Leucosep, CPT), and freezing method (Mr Frosty, Controlled Rate Freezing). Various parameters of the automated protocol using a CPT gradient on a Tecan liquid handler were optimized. Optimal protocols were validated in parallel for reproducibility and robustness. Optimization and validation were assessed in terms of cell yield, viability, recovery, white blood cell (WBC) subpopulation distribution, gene expression, and lymphoblastoid cell line (LCL) transformation. An initial centrifugation of whole blood at 2000 g was considered optimal for further processing, allowing isolation of plasma and PBMCs from a single sample. The three gradients gave similar outcomes in terms of cell yield, viability, and WBC subpopulation distribution. Ficoll showed some advantages and was selected for further evaluations. Optimization of the automated protocol script using a CPT gradient gave 61% cell recovery. No significant differences in quality, quantity, and WBC subpopulation distribution were seen between the two freezing methods, and Mr. Frosty was selected. The manual and automated protocols were reproducible in terms of quantity, recovery, viability, WBC subpopulation distribution, gene expression, and LCL transformation. Most (75%-100%) of the 13 robustness parameters were accepted for both methods with an 8 h pre-centrifugation delay versus 38%-85% after 24 h. Differences identified between the automated and manual methods were not considered consequential. We validated the first fully automated method for isolating viable PBMCs, including RNA analysis and generation of LCLs. We recommend processing within 8 h of blood collection.

    ABSTRACT: This is the third in a series of publications presenting formal method validation for biospecimen processing in the context of accreditation in laboratories and biobanks. We report here optimization of a stool processing protocol validated for fitness-for-purpose in terms of downstream DNA-based analyses. Stool collection was initially optimized in terms of sample input quantity and supernatant volume using canine stool. Three DNA extraction methods (PerkinElmer MSM I(®), Norgen Biotek All-In-One(®), MoBio PowerMag(®)) and six collection container types were evaluated with human stool in terms of DNA quantity and quality, DNA yield, and its reproducibility by spectrophotometry, spectrofluorometry, and quantitative PCR, DNA purity, SPUD assay, and 16S rRNA gene sequence-based taxonomic signatures. The optimal MSM I protocol involves a 0.2 g stool sample and 1000 μL supernatant. The MSM I extraction was superior in terms of DNA quantity and quality when compared to the other two methods tested. Optimal results were obtained with plain Sarstedt tubes (without stabilizer, requiring immediate freezing and storage at -20°C or -80°C) and Genotek tubes (with stabilizer and RT storage) in terms of DNA yields (total, human, bacterial, and double-stranded) according to spectrophotometry and spectrofluorometry, with low yield variability and good DNA purity. No inhibitors were identified at 25 ng/μL. The protocol was reproducible in terms of DNA yield among different stool aliquots. We validated a stool collection method suitable for downstream DNA metagenomic analysis. DNA extraction with the MSM I method using Genotek tubes was considered optimal, with simple logistics in terms of collection and shipment and offers the possibility of automation. Laboratories and biobanks should ensure protocol conditions are systematically recorded in the scope of accreditation.

    ABSTRACT: This study examined acceptability of two biobank consent models and evaluated the impact of beliefs about privacy and genetic safeguards on acceptance. U.S. adults surveyed online in English and Spanish were randomly assigned to one of two scenarios examining acceptance of broad consent (n=1528), or narrow consent (n=1533). Overall, willingness to provide broad (76%) and narrow (74%) consents were similar. African Americans were as likely as white non-Hispanics to accept narrow consent (72% vs. 77%, p=0.35) but significantly less likely to accept broad consent (69% vs. 81%, p=0.004). Education, insurance, and blood donation history were also related to acceptance. Adjusting for beliefs about privacy and policy protections (Genetic Information Nondiscrimination Act, GINA), the effects of the variables were reduced. Respondents who drew comfort from GINA were more likely to support both consent (both p<0.001); those who believed it is impossible to maintain privacy were less likely to find both broad (p=0.04) and narrow models acceptable (p=0.02). Choice of consent model matters when engaging diverse populations in biobank research. Beliefs underlying concerns about privacy and genetic protections should be considered when constructing biobank protocols.

    ABSTRACT: Isolation of high-quality RNA from tissue is mandatory for producing reliable data for downstream applications. In heart tissue, the relative strengths and weaknesses of different approaches to isolate total RNA are unknown. The objective of this study was to compare different RNA isolation methods in healthy and diseased human myocardium. Frozen left ventricular myocardium was obtained from individuals with heart failure and individuals who died from non-cardiac causes with normal heart function (control). Three extraction methods, including guanidine isothiocyanate (TRIzol), silica-gel column (RNeasy), and the combination method (TRIzol/RNeasy), were assessed for their effect on the yield, integrity, and gene expression levels of RNA using quantitative real-time PCR. In the control group (n=5), the highest RNA yield per tissue mass was obtained with TRIzol, and a significantly higher RNA integrity was obtained from the RNeasy method. The quantification cycle (Cq) values for both the reference gene GAPDH and two target genes were lower with TRIzol. Normalization by GAPDH showed the highest gene expression levels with RNeasy. Similar patterns were observed in the heart failure group (n=5), suggesting assays were not negatively impacted by myocardial disease processes. In both healthy and diseased heart tissue, the TRIzol method provides the highest RNA yield, while the RNeasy method shows superior RNA integrity, demonstrating comparable RNA quality in studies examining myocardial disease. A balanced approach to RNA quality is necessary for the successful downstream applications of RNA.

    ABSTRACT: Storage of labile RNA in laboratories is accomplished through ultra-low freezing of the nucleic acids. This however requires expensive freezers, convenient storage, reliable electrical power, and increased shipping costs, thereby making it a less viable option. Biomatrica (San Diego, CA) has created RNAstable(®), a stabilization reagent that is used to store RNA in a dehydrated state at room temperature (RT) and protects the RNA from degradation. Our objective was to investigate the sequence integrity and suitability of RNA when stored in RNAstable at extended time periods and at varying temperatures through use of Illumina and Agilent RNA expression microarrays. We observed in Bioanalyzer electropherograms that total RNA extracted from 293 cells stored at RT in RNAstable for 4.5 and 11.5 months is similar in quality to RNA stored at -80°C. Illumina mRNA expression array QC metrics and gene expression patterns from RNAstable-protected RNA, in contrast to RNA stored without RNAstable, correlated well with those of freezer controls. Significantly, when RNA was stored in RNAstable at 45°C for 4.5 months, equivalent to 22 months RT storage, RNA quality, microarray probe signal intensities, probe detection rates, and expression profiles remained similar between RNAstable-protected RNA at RT and the -80°C controls. At 10.5 months, miRNA levels were compared among the storage conditions using miRNA expression arrays. Here too we found strong concordance between miRNA expression patterns when total RNA was stored in RNAstable or at -80°C. Further, Bioanalyzer electrophoresis of RNAstable-protected samples stored at RT for a relative total of 33 months or 50.5 months showed comparable integrity scores to those of -80°C controls. We conclude that use of RNAstable holds promise as an effective stabilization reagent for total RNA and should be useful in situations where shipping and storage options are limited resources.

    ABSTRACT: Human tissue biorepositories have become key platforms for the acceleration of basic and translational biomedical research on cancer in China. The maintenance of sufficient amounts of tumor cells is critical for a wide variety of cancer studies. Ensuring the high quality of frozen stored tissue specimens is a crucial requirement. However, different tumor locations and various methods of tumor tissue removal can lead to variable numbers of tumor cells from banked tissue specimens. Thus, an effective method to assess the tumor cell content is essential for tissue samples in biobanks. In the present study, the mirror image method was used to evaluate the amount of tumor cells in stored tumor tissues of six common cancer types, including solid and hollow organ cancers. All tissues were stored in the Tianjin Medical University Cancer Institute and Hospital (TMUCIH). Histological assessment was performed by pathologists who conducted morphological diagnoses of tumor percentage on mirror image sections of frozen stored samples that were stained with hematoxylin and eosin (H&E). Results showed that the tumor percentage of solid organ cancers was higher than that of hollow organ cancers (χ(2)=17.11, p<0.0001). Among solid organ cancers, the highest tumor percentage was observed in renal tumor tissues, and likewise esophagus tumor tissues had the highest tumor content among hollow organ cancers (multiple tests, p<0.05). Three kinds of samples, which showed higher proportions of tumor content under 25%, were stomach, liver, and colorectal cancers, and the proportions were 15.0%, 10.9%, and 10.6%, respectively. Therefore, histological assessment based on the review of mirror-image H&E sections offers the most direct and objective judgment. The results can not only be applied to the tissue quality feedback process of biobanks, but also guide a wide variety of scientific studies.

    ABSTRACT: Genome-wide sequencing in glioma samples provides comprehensive insights into oncogenesis and malignant transformation. Several distinct biomarkers have been proven to have clinical significance and are being widely applied in routine clinical practice. Standard sample processing lays the foundation for successful molecular testing. In this study, we found intraoperative neuronavigation ensured higher tumor purity during sample collection, and an automated device helped improve DNA quality and increased yields. These two technologies are beneficial for glioma tissue bank construction and provide for accurate molecular testing during routine clinical practice.

    ABSTRACT: Background: Peripheral blood leukocytes (PBLs) are the main source of DNA in blood samples. A common protocol is to store buffy coat specimens for future DNA isolation, and such samples may remain in frozen storage for years. However, the currently available methods to maintain buffy coat specimens can be optimized for better quality and cost efficiency. Study Design and Methods: Seventeen donors (aged 24-34 years) were enrolled in this study. Initially, five centrifugal speeds were chosen to examine the distribution of PBLs in the cell layer; the buffy coat was then harvested to evaluate the cell quantity and viability after storing at 4°C for various times. Finally, the buffy coat was isolated, snap frozen, and kept at -80°C for 1 hour, 1 week, or 4 weeks until the DNA was extracted. Agarose gel electrophoresis and multiplex PCR were used to verify DNA integrity and amplifiability. Results: There was a linear positive correlation between the amount of fresh PBLs and the DNA yield. At least 70% of PBLs were collected in the uppermost 40% of the cellular material when the centrifugal force was over 800 g compared to 400 g. Storing blood at 4°C for no more than 24 hours did not have an effect on the amount of PBLs or their viability. In addition, the amount of extracted DNA was decreased in the frozen buffy coat that was stored for more than 7 days, though the DNA quality was acceptable. Conclusion: DNA should be extracted from fresh buffy coat samples as soon as possible after collection, especially for very important samples. Retaining the upper 40% of the cell pack of blood instead of whole blood could improve the storage efficiency of biobanking such samples. Our study provides a recommended option for blood collection and processing protocols in biobanking.

    ABSTRACT: Biobanks are important resources and central tools for translational medicine, which brings scientific research outcomes to clinical practice. The key purpose of biobanking in translational medicine and other medical research is to provide biological samples that are integrated with clinical information. In 2008, the Shanghai Municipal Government launched the "Shanghai Tissue Bank" in an effort to promote research in translational medicine. Now a sharing service platform has been constructed to integrate clinical practice and biological information that can be used in diverse medical and pharmaceutical research studies. The platform collects two kinds of data: sample data and clinical data. The sample data are obtained from the hospital biobank management system, and mainly include the donors' age, gender, marital status, sample source, sample type, collection time, deposit time, and storage method. The clinical data are collected from the "Hospital-Link" system (a medical information sharing system that connects 23 tertiary hospitals in Shanghai). The main contents include donors' corresponding medication information, test reports, inspection reports, and hospital information. As of the end of September 2014, the project has a collection of 16,020 donors and 148,282 samples, which were obtained from 12 medical institutions, and automatically acquired donors' corresponding clinical data from the "Hospital-Link" system for 6830 occurrences. This project will contribute to scientific research at medical institutions in Shanghai, and will also support the development of the biopharmaceutical industry. In this article, we will describe the significance, the construction phases, the application prospects, and benefits of the sample repository and information sharing service platform.

    ABSTRACT: Traditional nucleic acids preservation methods rely on maintaining samples in cold environments, which are costly to operate and time sensitive. Recent work validated that using room temperature for the storage of nucleic acids is possible if the samples are completely protected from water and oxygen. Here, we conducted accelerated aging and real-time degradation studies to evaluate the new technology DNAshell and RNAshell, which preserves DNA and RNA at room temperature, including the DNA and RNA yield, purity, and integrity. DNA and RNA solutions are dried in the presence of stabilizers in stainless steel minicapsules, then redissolved after different time points of heating and storing at room temperature. Results show that DNAshell and RNAshell ensure the safe storage of nucleic acids at room temperature for long periods of time, and that the quality of these nucleic acids is suitable for common downstream analysis.
