An analysis of the 39-member panel of HOX genes [31,32,33] revealed that HOXC4, HOXC5, HOXC6, and HOXC8 are overexpressed in prostate cancer cell lines and in the small set of examined prostate tumors (see also Figure 3C for an analysis of a larger set of prostate tumors). This evidence concerns the gene HOXC5 and prostate cancer.
