BACKGROUND Up to now, prostate-specific membrane antigen (PSMA)-targeted radionuclide therapy mainly focused on β-emitting radionuclides. Herein, two new 213Bi-labeled agents for PSMA-targeted α therapy of prostate cancer (PCa) are reported. METHODS The biodistribution of 213Bi-labeled small-molecule inhibitor PSMA I&T and nanobody JVZ-008 was evaluated in mice bearing PSMA-positive LNCaP xen...
UNLABELLED Prostate-specific membrane antigen (PSMA) overexpression theoretically enables targeting of prostate cancer (PCa) metastases using gallium Ga 68 ((68)Ga)-labeled PSMA ligands for positron emission tomography/computed tomography (PET/CT) imaging. Promising detection rates have been reported when using this approach for functional imaging of recurrent PCa; however, until now, the diagn...
UNLABELLED Prostate-specific membrane antigen (PSMA) is highly expressed in prostate cancer, and small-molecule radiopharmaceuticals targeting PSMA rapidly detect the location and extent of disease. Here we evaluated preclinically 4 novel (99m)Tc-labeled small-molecule inhibitors of PSMA with the potential for clinical translation for molecular imaging of prostate cancer in humans. METHODS Fo...
INTRODUCTION Prostate specific membrane antigen (PSMA) has become an attractive diagnostic and therapeutic target for small molecule ligands. Radionuclide-chelating ligands can be labeled with either 68Ga for positron-emission-tomography (PET) or 177Lu for radionuclide therapy. Areas covered: In this literature review we evaluate the diagnostic value of 68Ga PSMA PET/CT and the therapeutic pote...
Hormone-refractory prostate carcinomas as well as the neovasculature of different tumours express high levels of PSMA (prostate-specific membrane antigen). PSMA is a type II-transmembrane glycoprotein and a potential tumour marker for both diagnosis and passive immunotherapy. Here, we report on the association of PSMA with DRMs (detergent-resistant membranes) at different stages of the protein ...
The lack of a sensitive immunoassay for quantitating serum prostate-specific membrane antigen (PSMA) hinders its clinical utility as a diagnostic/prognostic biomarker. An innovative protein biochip immunoassay was used to quantitate and compare serum PSMA levels in healthy men and patients with either benign or malignant prostate disease. PSMA was captured from serum by anti-PSMA antibody bound...
The 68Ga-prostate-specific membrane antigen ( 68Ga-PSMA) has been recently developed to be used, as a ligand, in positron emission tomography/computed tomography (PET/CT) prostate cancer imaging, to detect prostate disease. The main objective of this review was to collect data and findings from other studies and articles to assess, theoretically, if 68GA-PSMA PET/CT is a more appropriate prosta...
BACKGROUND. Prostate specific membrane antigen (PSMA) is a unique folate hydrolase that is significantly upregulated in prostate cancer. In a mouse model, PSMA is able to facilitate prostate carcinogenesis, however, little is known about the mechanism by which this occurs. As PSMA is able to hydrolyze polyglutamated folates, and cancer cells proliferate directly in response to available folate,...
PURPOSE The restricted expression of the surface glycoprotein prostrate-specific membrane antigen (PSMA) to normal prostate tissue, primary and metastatic prostate cancer (PCa), and the neovasculature of various nonprostatic epithelial malignancies has enabled targeting strategies for PCa treatment using anti-PSMA antibodies. EXPERIMENTAL DESIGN Using prostatectomy specimens, immunohistochemi...
Prostate-specific membrane antigen (PSMA) is a membrane protein that is overexpressed manifold in prostate cancer and provides an attractive target for therapy. PSMA ADC is an antibody-drug conjugate (ADC) that consists of a fully human anti-PSMAmonoclonal antibody conjugated to monomethylauristatin E through a valine-citrulline linker. In this study, the antitumor activity of PSMA ADCwas evalu...
