17 INOVA -CTRF - Tissue Bank IRB has approved Tissue Acquisition at INOVA Consent form resubmitted to the IRB with changes to reflect the request that the consent would be signed after the biopsy was performed Marianne Smith’s group has identified Eileen Kelley as coordinator for tissue acquisition project –Study coordinator to obtain informed consent and acquisition

18 VCU Tissue Bank

19 Manual Form for Tissue Acquisition

20 Histopathologic Parameters

21 Tissue Acquisition Database Access Database –Computer has been installed at INOVA –Database has been installed on machine at VCU –INOVA connected to database at VCU using PC Anywhere (8-20-02) Update of Database for Histopathologic parameters of existing cases needed

23 Devitalization of Tissue Dr Nasim and Dr Grant

24 Tissue Devitalization Ovarian samples collected VCU –Tissue to be snap frozen over a time series Immediate snap freezing (time 0) Freeze extra pieces at 15, 30 and 60 and 120 minutes (from time 0). Frozen sections will be performed to monitor for purity of tumor. Sections cut and placed directly in TRIZOL and distributed. –RNA extracted and analyzed by both VCU and GMU teams for integrity over the period of experimentation

25  Temporary Storage (If appropriate)  -80°C freezer monitored 24hr X 7 days with daily recording of temperature; or, -80°C freezer monitored 5 days/wk with week day (including holiday) daily recording of temperatures and with liquid nitrogen back-up capable of maintaining -40°C for 72hr. (Note: liquid nitrogen back-up must include written quality assurance plan to insure that liquid N 2 maintained at satisfactory levels).  Permanent Storage  -80°C freezer maintained on an emergency power line (ie, line with back-up generator in case of system wide power loss) monitored 5 days/wk with week-day (including holiday) daily recording of temperatures and with liquid nitrogen back-up capable of maintaining -40°C for 72hr. (Note: liquid N 2 is maintained at satisfactory levels). Laboratory must have a plan for emergency storage of tissue specimens in the event of freezer failure including persons responsible to respond in the event of freezer failure and identification of alternative freezer space. Tissue Storage

26  Amount of Tissue  Based on current accessioning practices – for solid tumors (ie, breast, ovary [no VCU experience yet with brain]) – it is anticipated that each specimen will consist of approximately 200mg total weight and will contain 0.5 – 2.5  g total RNA per mg of tissue for a total of 100-500  g total RNA per sample. GMU requires ~20  g per run. VCU requires ~10  g per run for the Affymetirx platform. Supplying Tissue to Project PI Labs

27 Preparation of Tissue Samples In order to minimize the chances for RNA degradation and to monitor percent tumor cellularity as well as other potential confounding morphological changes (ie, inflammation, necrosis, desmoplasia, etc), tissue will be handled as follows:  blocks of tissue will be maintained frozen at all times.  blocks of tissue will be sectioned (5 μ thick) on a cryostat.  no more than 40 - 5 μ sections will be taken from any one sample without removal of a section for frozen section histology.  the tissue sections will be placed directly into cold Trizol, dispersed by vigorous shaking at the time of sectioning and maintained at -80 o C for storage and -37 o C (dry ice temp) for transportation. (Note: participating laboratories may request transportation solution other than Trizol based on their specific needs and experience.)  the standard sample will consist of Trizol with 40 section of tissue or the equivalent amount of total RNA.

28 Institutional Tissue Utilization Committee  Formulate criteria for who is eligible to obtain human residual samples at the institution. οFaculty status, IRB approval, ?scientific validity ο?minimum QA requirements ο?minimum data access requirements  Review requests for human tissue utilization.  Formulate criteria for the degree of clinical information which can be provided with the samples.  Assess resources required to fill request and whether PI is prepared to provide them.

33 RNA Degradation and Gene Expression Goal – To assess the impact of sample RNA degradation on the gene expression data from microarrays Protocol –Sample Type - Total RNA from the Ovary Sample (OV-169-001T) –Degradation Experiment – different degrees of degradation (to be determined)

34 RNA Degradation and Gene Expression Analysis of the sample – RNA degradation reflected by rRNA 28S/18S ratio (Agilent Bioanalyzer, Denaturing Gel, etc…) For Example : Agilent Ratio Sample 12.0-1.5 Sample 21 Sample 30.5 Sample 40.1

35 RNA Degradation and Gene Expression Microarray Data Analysis: –Find a common parameter to compare data across platforms (Ratio between Control genes for all the platforms against 1 Control Gene within the linear range of the system) –Check for changes in 3’5’ ratios for Housekeeping genes –Low and high abundance genes –Check for changes in gene calls (P – A)

36 Data Analysis Control Genes (GMU & VCU)

37 Within Platform Performance Assessment Each PI will perform quality assessment designed to measure the degree of variation due to each of the critical steps in the generation of results. PI Laboratories will use the Stratagene Human Reference mRNA (Product #: 740000-41) ( lot number 1000207 can be obtained from A. Christensen or A. Ferreira-Gonzalez) Written report summarizing findings will be prepared by PI laboratories Copy of report/manuscript will be provided to the Project Director’s Office Data for study to be treated as Project Data
