What is the Origin of Prostate-Specific Antigen (PSA)?

The antigen was first identified in the 1970s and subsequently developed into a robust clinical assay for prostate disease monitoring. The term is descriptive, directly naming the organ of origin and its protein nature as an antigen. Its widespread clinical use became a cornerstone of prostate cancer screening in the late 20th century, though its precise interpretation remains a subject of ongoing clinical refinement based on age and other factors.

What is the Mechanism of Prostate-Specific Antigen (PSA)?

PSA is normally secreted into the ducts of the prostate gland, and only a small, measurable amount normally leaks into the bloodstream. In conditions where the prostate architecture is disrupted, such as inflammation, infection, or malignancy, larger quantities of PSA are released into the circulation. Androgens, particularly testosterone and dihydrotestosterone (DHT), regulate the transcription of the PSA gene. Therefore, the mechanism involves both mechanical disruption of the prostate tissue and the underlying hormonal milieu that governs the total PSA production rate.

Prostate-Specific Antigen (PSA)

Meaning

Prostate-Specific Antigen (PSA) is a glycoprotein produced almost exclusively by the epithelial cells of the prostate gland, which functions primarily to liquefy semen following ejaculation. Clinically, PSA is utilized as a serum biomarker for the screening and monitoring of prostate health, including conditions like benign prostatic hyperplasia (BPH) and prostate cancer. Elevated or rapidly rising PSA levels can indicate a significant disruption in prostate tissue integrity, necessitating further urological and endocrinological investigation. The interpretation of PSA must be done within a clinical context.
