  2. Resource Description
    "The pathology core can construct custom TMA's for researchers who have large collections of their tissue of interest and would like to be able to perform "high-throughput" analysis. <b><i>Why do I need a TMA?</i></b> • Basic research: Validate and verify gene expression data • Translational research: Diagnostic markers, prognostic markers, theraputic markers, response to therapy, query signaling pathways, drug discovery, tissue is a valuable resource <b><i>What do I need to make a TMA?</i></b> • Source tissue: animal tissue, clinical archival tissue, prospectively acquired clinical tissue, associated data • Pathologist: Confirm diagnosis, select representative areas for sampling (<i>TMA cores are representative: 20 studies to date on a variety of tumors have shown strong correspondence in IHC results on TMAs when compared to "large" sections (n=3-4 cores)</i>, validate the constructed array, score the array. • Antibody or in situ probe to query array: phosphorylation state specific antibodies, signaling pathways • Data management and analysis tools • Willingness to have <b><i>many collaborators</i></b> <b><i>TMA data analysis</i></b> • IHC scoring — 0 negative — 1 indeterminate — 2 weakly positive — 3 strongly positive • Scores for each individual core in TMA are collected for every stain performed • Large data sets • Expression data can be analyzed by bioinformatic methods developed for cDNA microarrays • Quantitative scoring (pixel counts/percent area stained) can also be performed as well" Arrays that have been constructed previously can be found on the core's website.
