Series GSE7868 Query DataSets for GSE7868
Status Public on Sep 01, 2007
Title Expression data from LNCaP cell line
Organism Homo sapiens
Experiment type Expression profiling by array
Summary Androgen receptor (AR) is a ligand-dependent transcription factor that plays a key role in the onset and progression of prostate cancer. Surprisingly little is known of AR binding sites and collaborating transcription factors in the human genome. Here we have identified the DNA sequence motifs that are significantly enriched within the authentic 90 AR target regions found on chromosomes 21 and 22 in human prostate cancer cells by combining chromatin immunoprecipitation for AR with chromosome-scale tiled oligonucleotide microarrays. By integrating the DNA sequence motif data with the gene expression profiles from human prostate cancers we identified the transcription factors that recognize each of these motifs. These factors form complexes with AR, bind to specific AR target regions and govern androgen-dependent transcription. Together with AR these collaborating transcription factors form a regulatory network that directs prostate cancer growth and survival and identify potential new opportunities for therapeutic intervention.
Keywords: time course
Overall design The RNA samples are extracted from DHT 0, 4h and 16h treated LNCaP cells by using a RNeasy kit (Qiagen). The final RNAs submitted to Dana-Farber Cancer Institute (DFCI) Microarray Core Facility are all at 1.5ug/ul, A260/A280=2.1.
