Transcription profiling of human hormone resistant prostate cancer


ABSTRACT: In this study we performed transcriptional profiling of transurethral resections of hormone resistant prostate cancer and compared it with benign prostatic hyperplasia (BPH), untreated localized prostate cancer and hormone sensitive prostate cancer. Experiment Overall Design: Each sample (= Array) is derived from a different patient with the following subsequent disease states: 3x BPH, 7x localized prostate cancer samples, 2 horomone sensitive prostate cancer samples, one locally advanced prostate cancer, 4x hormone resistant prostate cancer early stage and 3x hormone resistant prostate cancer late stage. Experiment Overall Design: Platform was Affymetrix

ORGANISM(S): Homo sapiens

The molecular mechanisms for hormone-resistant prostate cancer progression still remain elusive, mainly due to the limited availability of corresponding tissue. As transurethral resection (TUR) is a common palliative therapy for patients with hormone refractory prostate cancer (HRPC) who have subvesical obstruction, we aimed to demonstrate that TUR samples can be used to identify significantly affected biological pathways during the switch to HRPC using oligonucleotide microarray analysis.
