OBJECTIVE To assess the expression of forkhead transcription factors (FOX) in normal prostate and prostate diseases, as since the first FOX was identified, its family members have been implicated in a variety of cellular processes, including embryonic development and disease. MATERIAL AND METHODS We analysed a set of 12 different FOX genes by quantitative reverse transcription-polymerase chain reaction in prostate zones, prostate cancer, lymph node metastases, benign prostatic hyperplasia (BPH), xenografts and several prostate cell lines. RESULTS There were striking differences among the expression of various FOX family members; most prominent were the high expression of FOXF1 and FOXF2 in the normal prostate transition zone and BPH, and their decreased expression in prostate cancer. Interestingly, although the FOXF genes are stroma-specific, some of the androgen-independent prostate cancer xenografts uniquely express these two genes. FOXD1 and FOXD2 were more highly expressed in prostate cancer and lymph node metastases. FOXA1 and FOXC1 have an opposite expression pattern for androgen-dependent growth of prostate cancer cell lines and xenografts. CONCLUSIONS Various members of the FOX family are differentially expressed in the zones of the normal prostate and in benign and malignant outgrowths. The expression profiles of FOXF1 and FOXF2 suggest a role in epithelial to mesenchymal transition, while FOXA1 and FOXC1 expression is linked to androgen-associated growth status of cancer.

D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011467	Prostate	A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.	Prostates
D011468	Prostatectomy	Complete or partial surgical removal of the prostate. Three primary approaches are commonly employed: suprapubic - removal through an incision above the pubis and through the urinary bladder; retropubic - as for suprapubic but without entering the urinary bladder; and transurethral (TRANSURETHRAL RESECTION OF PROSTATE).

D011470	Prostatic Hyperplasia	Increase in constituent cells in the PROSTATE, leading to enlargement of the organ (hypertrophy) and adverse impact on the lower urinary tract function. This can be caused by increased rate of cell proliferation, reduced rate of cell death, or both.
