24 © 2002 VCU GMU Informatics Update Create or Identify existing databases into which expression microarray data can be stored in electronic format in real time at this juncture. –Identified GeneX as candidate microarray database. –Worked with GeneX developers and UVA to modify GeneX to accept both cDNA and Affymetrix gene expression data –Instantiated new version of GeneX –Defined new LIMS schema for data management Create or Identify existing databases into which clinical, laboratory, tissue bank information, and expression microarray can be stored in electronic format in real time at this juncture. –Examined several available clinical databases and found none to be sufficient in terms of performance and flexibility. –Used CGO as starting basis to generate new clinical schema. –Currently implementing clinical databases. Create ODBC links between separate databases containing clinical, laboratory, and tissue bank data. –In progress.

25 © 2002 VCU CTRF CA GENOMICS TISSUE UTILIZATION - PLAN

26 © 2002 VCU Choice of the RNA Extraction Procedure for Best Microarray Results (I) Starting material: 10  m OCT sections of snap- frozen tissue (in liquid N 2 ) T RIZOL (Invitrogen) Or T RIZOL (Invitrogen) + RNeasy cleanup (QIAGEN)

27 © 2002 VCU T RIZOL + RNeasy cleanup T RIZOL RNA extraction ds cDNA synthesis 1,500 bp ~ 50 bp 28S/18S ratio: 1.9 28S/18S ratio: 1.8

28 © 2002 VCU Results (I) By using T RIZOL we obtained undegraded RNA (28S/18S >1.5) but the cDNA synthesis was inhibited (accumulation of short, ~50 bp, molecules). By cleaning up the RNA isolated using T RIZOL with the RNeasy cleanup protocol, we obtained cDNA molecules of greater size, with a max. peak at ~1,500 bp.

29 © 2002 VCU Choice of the RNA Extraction Procedure for Best Microarray Results (II) Starting material: Snap-frozen tissue (in liquid N 2 ), 10  m OCT sections dumped in a solution containing guanidinium thiocyanate (RNAse inhibitor): T RIZOL (Invitrogen) + RNeasy cleanup (QIAGEN) or RLT from RNeasy - Solution D ( Chomczynski P and Sacchi N)

30 © 2002 VCU T RIZOL + RNeasy cleanup RNeasy Isolation 28S/18S ratio: 1.9 28S/18S ratio: 0.2 RNA extraction ds cDNA synthesis 1,500 bp 500 bp

31 © 2002 VCU Results (II) By using the RNeasy RNA isolation protocol from breast tissue sections, we obtained total RNA with 28S/18S ratios << 1.5, and the cDNA molecules were shorter than expected (max. peak at ~500 bp). Therefore, we decided to isolate the RNA using T RIZOL followed by the RNeasy cleanup protocol, to ensure cDNA molecules of greater size, (max. peak at ~1,500 bp).
