Prostate-Specific Membrane Antigen (PSMA) is a glycoprotein that plays a role in various physiological processes, including folate homeostasis...PSMA-617 and Ac-PSMA-617. "Vipivotide" refers to thepeptide-based targeting moiety (Lys-urea-Glu) that binds specifically to prostate-specific membrane .... However, its significance in oncology stems from its overexpression in prostate cancer cells, especially in advanced stages and metastatic disease. This elevated expression makes PSMA a prime target for therapeutic interventions and diagnostic imaging作者：MW Chen·2025—PSMA-Targeted RadiolabeledPeptidefor Imaging and Therapy in Prostate Cancer: Preclinical Evaluation of Biodistribution and Therapeutic Efficacy. Ming Wei .... While PSMA is found at low levels in normal tissues like salivary glands and kidneys, its significantly higher concentration in tumors allows for selective targeting. Understanding the difference between PSMA and other related markers, such as PSA (Prostate-Specific Antigen), is crucial for accurate diagnosis and treatment planning.
Peptides, with their small size and high specificity, are ideal candidates for developing PSMA-targeting agents. These peptides can be engineered to bind specifically to PSMA, acting as carriers for diagnostic imaging agents or therapeutic payloads.
* Diagnostic Imaging: PSMA-specific peptides can be radiolabeled and used in Positron Emission Tomography (PET) scans (e.作者：F Lundmark·2024—Two key biomarkers are prostate- specific membrane antigen (PSMA) and gastrin-releasingpeptidereceptor (GRPR) which are overexpressed in ...g., PSMA-PET/CT) to detect and stage prostate cancer with high accuracy. This allows clinicians to visualize tumor locations and assess the extent of the disease more effectively than traditional methods.
