What is the Meaning of Prostate-Specific Antigen?

Prostate-Specific Antigen, or PSA, is a glycoprotein enzyme produced almost exclusively by the epithelial cells of the prostate gland, which functions primarily to liquefy semen. Clinically, it serves as a critical biomarker measured in serum to screen for and monitor prostate pathology, including benign prostatic hyperplasia (BPH) and prostate carcinoma. While elevated PSA levels warrant further investigation, the interpretation must consider age, prostate volume, and the influence of sex hormones, particularly testosterone and estrogen, which directly regulate prostate cell proliferation and PSA production.

What is the Origin of Prostate-Specific Antigen?

PSA was first isolated and characterized in the 1970s, and its clinical utility as a serum marker for prostate disease was established in the 1980s, fundamentally changing the landscape of prostate cancer screening. The term is a direct, functional description of the protein's origin and antigenic properties. Its etymology is purely descriptive, naming the protein for the gland that produces it and its ability to elicit an antibody response.

What is the Mechanism of Prostate-Specific Antigen?

The production of PSA is fundamentally regulated by androgens, primarily dihydrotestosterone (DHT), which binds to androgen receptors in prostate cells and stimulates the transcription of the PSA gene. Therefore, the mechanism links directly to the HPG axis, as circulating testosterone levels influence PSA expression. Clinical interventions, such as testosterone replacement therapy, can influence PSA levels by increasing the substrate for DHT conversion, requiring careful monitoring to distinguish between a hormonally driven change and a pathological increase.
