The Tissue Processing/Sequencing Core (TPSC) is essential in providing support and resources for the Urologic Oncology Branch (UOB) and for our collaborators. The TPSC handles every biospecimen that is generated within the UOB, processes each specimen in order to preserve biomolecules, keeps an accurate inventory of each procurement, and assists in the scientific analysis of select specimens, for the ultimate goal of elucidating biological pathways relating to kidney, prostate, and bladder cancers. The TPSC processes tissue from nearly 100% of UOB surgeries, as well as a subset of biopsies and other procedures. Typically, there are 3 to 5 surgeries and 2 to 6 biopsies per week, resulting in tissue samples procured from over 300 patients per year, including kidney, prostate, and bladder carcinomas, adrenal tumors, uterine leiomyomas, lymph node metastases, and other specimens relating to sporadic and familial urologic cancer syndromes. Tissue is always procured in cooperation with Surgical Pathology, to ensure proper handling and accurate diagnosis. Tissue is snap frozen, preserved in formalin or glutaraldehyde, or processed for biomolecule (DNA, RNA, protein) purification and analysis. In addition, DNA is regularly prepared from blood samples taken from patients with inherited syndromes. Serum or plasma, whole blood, or RNA may also be procured and stored from select patients. Two to three dozen blood samples may be processed per week. Finally, the core may also procure and process urine, ascites or thoracic fluids, cyst fluids, or other body fluids from medical procedures. Frozen samples are stored in liquid nitrogen or a -80 degree centigrade freezer. Specimens are assigned a de-identified lab number and entered into a secure database, Labmatrix. Over 2,000 tissue and blood specimens have been procured within the last year. The entire UOB tissue repository contains in excess of 20,000 tissue samples and DNA from 2,500 blood samples from over 1,200 patients. Most of the samples were collected at the NIH Clinical Center, and full patient histories are incorporated into Labmatrix. Older samples are currently in the FreezerWorks biorepository. A future goal is for all clinical and laboratory findings to be incorporated into Labmatrix to provide an accessible resource for all of our studies from bench to bedside. A key function of the TPSC is to support clinical trials within the Branch. We are currently involved in two active clinical trials: Bevacizumab and Erlotinib for patients with metastatic papillary kidney cancer or HLRCC (36 patients accrued to date), and AstraZeneca ZD6474 for patients with VHL syndrome (34 patients accrued to date). Blood samples are processed regularly by the TPSC, for the purpose of investigating pharmacodynamic and phamacokinetic effects of the drugs, as well as other cancer biomarkers. A new clinical trial using a Met kinase inhibitor for papillary kidney cancer patients is expected to begin this year. Many of the tumor samples from kidney cancer surgeries are procured under sterile conditions to establish new cell cultures and mouse xenografts. We have generated over 300 kidney cancer cell lines, 43 of which have been extensively characterized for cancer gene mutations. Lines have been generated from hereditary kidney cancer syndromes (BHD, SDHB, VHL, and 4 HLRCC lines) that provide unique reagents. In the last year, over a dozen kidney tumors and a few prostate and bladder tumors have been placed in cell culture and/or in SCID/BEIG or nude mice, with a subset of these growing viably in the short-term and a small number (2 this year) that become immortal. These lines are invaluable for studying both the molecular basis of tumorigenesis and prospective therapies. Cell lines are kept in standard carbon dioxide or low oxygen incubators or stored in liquid nitrogen, and mice are housed in an appropriate on-site facility. The hereditary lines are being extensively characterized by DNA sequencing of selected genes, array CGH, realtime PCR, Western blotting, oxygen consumption and extracellular acidification rate, and metabolomics. The Branch has also generated immortal B cell line samples from several hundred UOB patients from families with VHL, BHD, HPRC, HLRCC, or unknown familial kidney cancer syndromes. These lines provide an unlimited resource for germline DNA for characterization of known genetic aberrations, as well as the potential to discover new genes that may involved in inherited kidney cancer in as-yet undiagnosed patients. In addition, these lines provide the opportunity to study genes of interest at the RNA level. The collection of DNA samples for the detection and characterization of germline disease mutations has been at the heart of the gene discovery process in the UOB. Several dozen blood samples per year are analyzed by DNA sequencing, comparative genome hybridization (CGH) analysis, fluorescent in-situ hybridization (FISH), and/or other genetic studies. Furthermore, during a three-year study using array CGH, we have performed fine mapping of germline deletions in 67 VHL families, 8 BHD families, 7 HLRCC families and 2 SDHB families, as well as one novel partial gene duplication in a BHD family. The goal has been twofold: to characterize previously undiagnosed clinically affected patients, and to correlate the sizes and locations of these deletions with the severity of disease and/or response to clinical treatments. We continue to use these techniques to discover new mutations, deletions, and amplifications. Both frozen and formalin-fixed tissues from kidney, prostate, and bladder cancers that have been processed by the TPSC have been characterized extensively in the UOB by immunohistochemistry, quantitative PCR, expression microarrays, Northern and Western blotting, immunoprecipitation, and DNA sequencing. Glutaraldehyde-fixed tissues have been used for electron microscopy, in order to characterize subcellular organelles. Proper handling of our surgical specimens has been an essential factor in assuring the best quality laboratory results. The UOB is involved in providing aliquots of many of its procured tumor tissues and blood samples to collaborating laboratories. The Branch has long-standing collaborations in which we distribute tissue to other laboratories for cell culture and immunotherapy for kidney cancer patients, analysis of kidney cancer cellular markers, cancer gene mutation analysis, protein and RNA studies of adrenal masses (pheochromocytomas), and molecular epidemiology studies of prostate cancers. We are now participating in the Cancer Genome Atlas (TCGA) project by contributing clear cell, papillary and chromophobe kidney cancers, and are currently collecting prostate specimens to be sent to the TCGA this fall. The sizeable biospecimen collection amassed by the UOB over the last 25 years provides an invaluable resource for both basic and clinical research regarding kidney, prostate and bladder cancers.

组织处理/测序核心 (TPSC) 对于为泌尿肿瘤科 (UOB) 和我们的合作者提供支持和资源至关重要。 TPSC 处理大华银行内生成的每个生物样本，处理每个样本以保存生物分子，保留每次采购的准确库存，并协助对选定样本进行科学分析，以实现阐明与肾脏相关的生物学途径的最终目标、前列腺癌和膀胱癌。 TPSC 处理来自近 100% UOB 手术的组织，以及一部分活检和其他手术。通常，每周进行 3 至 5 次手术和 2 至 6 次活检，每年从 300 多名患者采集组织样本，包括肾癌、前列腺癌和膀胱癌、肾上腺肿瘤、子宫肌瘤、淋巴结转移瘤和其他样本与散发性和家族性泌尿系统癌症综合征有关。组织始终与外科病理学合作采购，以确保正确处理和准确诊断。组织被速冻、保存在福尔马林或戊二醛中，或进行处理以进行生物分子（DNA、RNA、蛋白质）纯化和分析。此外，定期从遗传综合征患者的血液样本中制备 DNA。血清或血浆、全血或 RNA 也可以从选定的患者处获取和储存。每周可处理两到三打血液样本。最后，核心还可以获取和处理来自医疗程序的尿液、腹水或胸液、囊肿液或其他体液。冷冻样品储存在液氮或-80℃冰箱中。样本被分配一个去识别化的实验室编号，并输入安全数据库 Labmatrix。去年已采购了 2,000 多份组织和血液样本。整个大华银行组织储存库包含超过 20,000 个组织样本以及来自 1,200 多名患者的 2,500 个血液样本的 DNA。大部分样本是在 NIH 临床中心收集的，完整的患者病史均已纳入 Labmatrix。较旧的样本目前位于 FreezerWorks 生物存储库中。未来的目标是将所有临床和实验室发现纳入 Labmatrix，为我们从实验室到临床的所有研究提供可访问的资源。 TPSC 的一项关键职能是支持分部内的临床试验。我们目前正在进行两项临床试验：针对转移性乳头状肾癌或 HLRCC 患者的贝伐珠单抗和厄洛替尼（迄今为止已累计 36 名患者），以及针对 VHL 综合征患者的阿斯利康 ZD6474（迄今为止已累计 34 名患者）。 TPSC 定期处理血液样本，以研究药物以及其他癌症生物标志物的药效学和药代动力学效应。一项使用 Met 激酶抑制剂治疗乳头状肾癌患者的新临床试验预计将于今年开始。许多来自肾癌手术的肿瘤样本都是在无菌条件下获得的，以建立新的细胞培养物和小鼠异种移植物。我们已经产生了 300 多种肾癌细胞系，其中 43 种已被广泛表征为癌症基因突变。遗传性肾癌综合征的细胞系（BHD、SDHB、VHL 和 4 个 HLRCC 细胞系）产生，可提供独特的试剂。去年，十多个肾肿瘤以及一些前列腺和膀胱肿瘤已被置于细胞培养物和/或 SCID/BEIG 或裸鼠中，其中一部分在短期内存活且数量很少。 （今年2）即成仙。这些细胞系对于研究肿瘤发生的分子基础和前瞻性治疗具有无价的价值。细胞系保存在标准二氧化碳或低氧培养箱中或储存在液氮中，小鼠则饲养在适当的现场设施中。通过选定基因的 DNA 测序、阵列 CGH、实时 PCR、蛋白质印迹、耗氧量和细胞外酸化率以及代谢组学，对遗传系进行了广泛的表征。该分支机构还从数百名来自 VHL、BHD、HPRC、HLRCC 或未知家族性肾癌综合征家族的 UOB 患者中生成了永生 B 细胞系样本。这些细胞系为种系 DNA 提供了无限的资源，用于表征已知的遗传畸变，并有可能在尚未确诊的患者中发现可能与遗传性肾癌有关的新基因。此外，这些细胞系还提供了在 RNA 水平上研究感兴趣基因的机会。用于检测和表征种系疾病突变的 DNA 样本收集一直是 UOB 基因发现过程的核心。每年通过 DNA 测序、比较基因组杂交 (CGH) 分析、荧光原位杂交 (FISH) 和/或其他遗传学研究来分析几十个血液样本。此外，在使用阵列 CGH 的一项为期三年的研究中，我们对 67 个 VHL 家族、8 个 BHD 家族、7 个 HLRCC 家族和 2 个 SDHB 家族中的种系缺失以及 BHD 家族中一个新的部分基因重复进行了精细定位。目标有两个：描述先前未诊断的临床受影响患者的特征，并将这些缺失的大小和位置与疾病的严重程度和/或对临床治疗的反应相关联。我们继续使用这些技术来发现新的突变、缺失和扩增。 TPSC 处理的肾癌、前列腺癌和膀胱癌的冷冻和福尔马林固定组织已在 UOB 中通过免疫组织化学、定量 PCR、表达微阵列、Northern 和 Western 印迹、免疫沉淀和 DNA 测序进行了广泛的表征。戊二醛固定的组织已用于电子显微镜，以表征亚细胞器。正确处理我们的手术标本是确保最佳质量实验室结果的重要因素。大华银行参与向合作实验室提供其采购的许多肿瘤组织和血液样本的等分试样。该分部与其他实验室有着长期的合作关系，我们将组织分发给其他实验室，用于肾癌患者的细胞培养和免疫治疗、肾癌细胞标志物分析、癌症基因突变分析、肾上腺肿块（嗜铬细胞瘤）的蛋白质和RNA研究以及分子生物学研究。前列腺癌的流行病学研究。我们现在正在参与癌症基因组图谱 (TCGA) 项目，贡献透明细胞癌、乳头状肾癌和嫌色肾癌，目前正在收集前列腺样本，将于今年秋天发送到 TCGA。大华银行在过去 25 年中收集的大量生物样本为肾癌、前列腺癌和膀胱癌的基础和临床研究提供了宝贵的资源。
