  • Title: Binding of epidermal growth factor by human normal, hypertrophic, and carcinomatous prostate.
    Author: Davies P, Eaton CL.
    Journal: Prostate; 1989; 14(2):123-32. PubMed ID: 2469072.
    Abstract:
    Saturable binding sites for radioiodinated epidermal growth factor (EGF) have been quantified in surgical specimens of benign prostate hypertrophy (BPH), histologically normal (HN) prostate, and prostate cancer. Values for EGF binding did not differ significantly between HN prostate and prostate cancer, although dedifferentiated samples tended to higher levels. These were coincident with lower comparative levels of androgen receptors. Unfractionated BPH tissue contained lower levels of EGF binding than either HN or carcinomatous prostate, but in separated epithelial cells EGF binding fell into the same range. Saturation analyses showed two affinity classes of binding in all except dedifferentiated tissues.
