Unsupervised hierarchical cluster of amplified prostate needle core biopsies. Expression patterns of amplified miRNA from a small set of clinical prostate specimens. Cluster analysis of the microarrays displayed shows a cluster on the left consisting of an advanced needle core biopsy of an advanced prostatic tumor (Gleason score 8) and a fine needle aspirate of a prostatic lymph node metastasis (FNA), a cluster in the middle consisting of PC3 and LNCaP prostate tumor cell lines, and a cluster on the right consisting of a pooled normal adjacent to tumor sample and another sample consisting of transitional cell metaplasia (TCM), an early precursor lesion.
