The present invention relates to compositions and methods for the detecting, treating, and empirically investigating cellular proliferation disorders and cellular motility disorders. In particular, the present invention provides compositions and methods for using CXCL chemokines (e.g., CXCL1, CXCL5, CXCL6, CXCL12), CXCL receptors (e.g., CXCR1, CXCR2, CXCR4, CXCR7), and/or pathway related compounds (e.g., NF-kappaB, ERK 1/2, ELK-1) in the diagnosis, treatment, and empirical investigation of prostate disorders (e.g., prostate cancer, benign prostatic hypertrophy, prostatitis).
