    Prostate cancer shows normal proteolytic activity, while benign prostatic hypertrophy significantly reduces it. This study isolated and characterized prostate pepsinogen, finding it identical to gastric progastricsin.

    Area of Science:

    • Biochemistry
    • Urology
    • Oncology

    Context:

    • Investigating proteolytic enzymes in the prostate.
    • Comparing enzyme activity across normal, benign hypertrophic, and cancerous prostate tissues.
    • Characterizing pepsinogen isolated from the normal prostate.

    Purpose:

    • To quantify and compare the proteolytic activity in normal, benign hypertrophic, and cancerous prostate tissues.
    • To isolate and identify pepsinogen from the normal prostate.
    • To assess the role of proteolytic activity in prostate pathologies.

    Summary:

    • Pepsinogen from normal prostate was isolated and identified as identical to gastric progastricsin.
    • Proteolytic activity in cancerous prostate tissue was comparable to normal prostate tissue.

  • Benign prostatic hypertrophy showed markedly reduced proteolytic activity, especially with synthetic substrates.

    • Impact:

    • Highlights significant differences in proteolytic activity between benign prostatic hypertrophy and normal/cancerous prostate tissue.
    • Provides insights into biochemical changes associated with prostate diseases.
    • Suggests potential diagnostic or therapeutic targets related to prostate enzyme activity.
