Prostate-Specific Membrane Antigen (PSMA) is a transmembrane glycoprotein highly expressed in prostate cancer cells, with limited presence in normal tissues. Its gene, *FOLH1*, encodes a 750-amino-acid protein with a glutamate-carboxypeptidase enzymatic domain, involved in folate metabolism and cell signaling. PSMA's overexpression in prostate cancer, particularly in advanced, metastatic, or hormone-resistant cases, has made it a pivotal biomarker and therapeutic target.
PSMA-targeting antibodies, engineered to bind specifically to its extracellular domain, have revolutionized diagnostic and therapeutic approaches. In diagnostics, radiolabeled PSMA antibodies (e.g., ⁶⁸Ga-PSMA-11) enable precise PET/CT imaging for tumor localization and staging. Therapeutically, antibody-drug conjugates (ADCs) and radioimmunoconjugates (e.g., ¹⁷⁷Lu-PSMA-617) deliver cytotoxic payloads directly to cancer cells, sparing healthy tissues. These therapies show promise in extending survival in castration-resistant prostate cancer.
Beyond prostate cancer, PSMA expression in neovasculature of other solid tumors (e.g., glioblastoma, renal cell carcinoma) has expanded its clinical relevance. Challenges remain, including tumor heterogeneity and variable antigen density, driving research into bispecific antibodies, combination therapies, and improved imaging agents. Ongoing trials aim to optimize dosing, reduce toxicity, and explore PSMA's role in immunotherapy, solidifying its status as a cornerstone of precision oncology.
