Purification and partial characterization of prostate-derived growth factor. 1986

S Maehama, and D Li, and H Nanri, and J F Leykam, and T F Deuel

A potent growth-promoting polypeptide, the prostate-derived growth factor (PrDGF), has been purified to apparent homogeneity from acid extracts of rat prostatic tissue using ion-exchange, reverse-phase, and gel-permeation chromatography. PrDGF migrates as a single protein-staining band in NaDodSO4/PAGE in precise correspondence to extractable PrDGF activity in nonstained NaDodSO4 gels. PrDGF is acid- and heat-stable but is sensitive to reduction or protease treatment. PrDGF is an acidic (pI 5.0) protein of approximately equal to 25 kDa in NaDodSO4/polyacrylamide gels and of approximately equal to 6-8 kDa in reduced NaDodSO4/polyacrylamide gels. PrDGF stimulates the linear incorporation of [methyl-3H]thymidine into normal rat kidney cells between 0 and 16 ng/ml. PrDGF appears to differ from other known growth factors in chemical composition and biological properties, suggesting that PrDGF is a previously undescribed growth factor.

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
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.
