Lactoferrin in human prostate tissue.

M van Sande, K Van Camp

    Urological Research
    |January 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Lactoferrin levels are lower in benign prostatic hyperplasia median lobes and decrease with hormone treatment. Prostatic adenocarcinoma tissue shows very low lactoferrin, indicating its hormone-dependent, bacteriostatic role.

    Area of Science:

    • Urology
    • Biochemistry
    • Oncology

    Background:

    • Lactoferrin, an iron-binding protein, plays a role in immune defense.
    • Prostate conditions like benign prostatic hyperplasia (BPH) and prostate adenocarcinoma are common in aging men.
    • Hormonal influences are known to affect prostate tissue composition and function.

    Purpose of the Study:

    • To quantify lactoferrin levels in human prostate tissues.
    • To investigate the impact of benign prostatic hyperplasia and prostate adenocarcinoma on lactoferrin concentration.
    • To explore the relationship between hormonal treatments and lactoferrin levels in BPH.

    Main Methods:

    • Radial immunodiffusion assay was used to determine lactoferrin levels.
    • Analysis was performed on homogenates of human benign prostatic hypertrophy and prostatic adenocarcinoma tissues.

  • Patient tissues included those from untreated BPH, BPH treated with oestrogens or antiandrogens, and prostate adenocarcinoma.

    • Main Results:

    • Untreated benign prostatic hyperplasia showed significantly lower lactoferrin levels in median lobes compared to lateral lobes.
    • Hormonal treatments (oestrogens, antiandrogens) in BPH patients led to decreased lactoferrin concentrations.
    • Prostate adenocarcinoma tissue, whether from open surgery or transurethral resection, exhibited very low lactoferrin levels.

    Conclusions:

    • Lactoferrin concentration in the human prostate is hormone-dependent.
    • Reduced lactoferrin levels are associated with both benign prostatic hyperplasia and prostate adenocarcinoma.
    • Lactoferrin's bacteriostatic role in the prostate may be influenced by hormonal status.
