  44. 55. Experimental Design <ul><li>Choice of reference : Common (non-biologically relevant) reference, or paired samples? </li></ul><ul><li>Number of replicates : how many are needed? (How many are affordable...?). Are the replicate results going to be averaged or treated independently? </li></ul><ul><li>Dye switches ? </li></ul><ul><li>Choice of data base : where and how to store the data? </li></ul>

What SAM does: <ul><li>SAM assigns a score to each genes on the basis of the change in gene expression relative to the standard deviation of repeated measurements. </li></ul><ul><li>For genes with scores above a certain threshold (set by the user), SAM uses permutations of the repeated measurements to estimate the % of genes identified by chance = the false discovery rate (FDR). </li></ul>
  54. 65. Every cell in the body has the same genetic constitution. In cancer cells there is usually acquired aberrant DNA Development of “cancer genomics” to better understand the molecular basis of acquired genetic change Breast Ovary Prostate

  58. 69. Tumor heterogeneity challenge <ul><li>**Some cancers, such as prostate cancer, are multifocal / heterogeneous . </li></ul><ul><li>**For these tumors, “bulk” extraction of genetic material from tumor tissue will produce microarray results that are “contaminated” by normal or pre-malignant tissue </li></ul>
