PCA, Spearman's rank correlations, quadratic regression classification and cross-validation were programmed in MatLab release 12.
Subsequent cycles of clustering were initialized similarly, except that PCA was performed on the respective data subset used in that clustering cycle.
PCA is a statistical technique to reduce the dimensionality of a dataset while retaining as much of the variability as possible [ 15 ] . Each principal component captures as much variability as possible with a linear combination of the data and is uncorrelated with all other principal components.
We were curious to know whether the expression changes observed in LNCaP would also occur in other androgen-responsive human prostate cancer cell lines (MDA PCa 2a, MDA PCa 2b, and LAPC-4), or in LNCaP and LAPC-4 subclones carried in androgen-depleted conditions for extended periods.
An association between autocrine IL-6 and PCA has been known for some time [ 16 17 ] . The change in prostate cell phenotype from paracrine IL-6-stimulated to autocrine IL-6-stimulated is believed to be a contributing factor in the progression from benign hyperplasia to neoplasia [ 17 ] . IL-6 is also implicated in the development of cancer cell resistance to chemotherapy in PCA patients [ 18 19 ] . In other studies, a chimeric protein consisting of an anti-IL-6 Ab fused to Pseudomonas exotoxin was found to inhibit proliferation of prostate carcinoma cell lines [ 20 ] . Exogenous IL-6 activated androgen responsive gene expression in the absence of androgens in human LNCaP cells [ 21 ] . More work is needed to clarify the role of IL-6 in prostate neoplasia.
