Using the TaqMan Low Density Array (TLDA) technology, we evaluated the expression of the five ETS genes known to be involved in genomic rearrangements in PCa (ERG, ETV1, ETV4, ETV5 and FLI1) in a panel of cell lines representing various subtypes of prostate cancer (Figure 1A). The gene discussed is FLI1; the disease is Familial prostate cancer.
