Yet it is the epithelium that gives rise to life-threatening prostate cancer [ 11,12 ]. This is termed a cDNA library.

Therefore, an improved method called serial analysis of gene expression SAGE is also used.

A similar difficulty would arise were the control pool to contain libraries with few ESTs. In addition, a control pool should consist of several diverse libraries with many sequences. Although these results have proven extremely useful, a serious drawback to the sequencing of bulk tissue cDNA libraries is the lack of gene expression information in the context of tumor biology.

Practically, issues arose which CGAP accounted for as new technologies became available. This was performed in a series of steps: [3] Cell contents are washed over plates with poly T sequences.

The expectation of determining the genetic fingerprints of cancer progression will allow for 1 correlation of disease progression with therapeutic outcome; 2 improved evaluation of disease treatment; 3 stimulation of novel approaches to prevention, detection, and therapy; and 4 enhanced diagnostic tools for clinical applications. This cellular heterogeneity made gene expression information in terms of cancer biology less accurate. LCM is a process by which one is able to procure selected groups of cells, or even individual cells, from a heterogeneous population of cells in standard pathology preparations. Each bacterium now contains one unique cDNA and is replicated to produce clones with the same genetic information. In addition, a control pool should consist of several diverse libraries with many sequences. Below are some of the initiatives or research tools provided by CGAP. This utility uses the Fisher exact test [ 17 ] to compare one library to another, a pool of libraries to a single library, or a pool of libraries against another pool. SNPs are valuable in cancer research as they can be used in several different genetic studies, commonly to track transmission, identify alternate forms of genes and analyze complex molecular pathways that regulate cell metabolism, growth, or differentiation. The resulting double stranded DNA is then incorporated into E.

Establishment of the TGI is being done by constructing cDNA libraries from pathological tissue followed by high-throughput library sequencing. SAGE libraries have better read quality and generate a larger amount of data when sequenced, and since transcripts are compared in absolute rather than relative levels, SAGE has the advantage of requiring no normalisation of data via comparison with a reference.
