Other genes identified that have been reported as androgen-regulated or involved in BPH or prostate cancer included PTGDS (prostaglandin D2 synthase), FGFBP1 (fibroblast growth factor binding protein 1), KLK11 (kallikrein 11), CXCL5 (chemokine (C-X-C motif) ligand 5), FKBP11 (FK506-binding protein 11) and TIMP1 (tissue inhibitor of metalloproteinase 1). Here, TIMP1 is linked to prostate carcinoma.
