This study aims to evaluate the effect on killing efficacy of the intracellular trafficking patterns of α-particle emitters by using different radionuclide carriers in the setting of targeted antivascular α-radiotherapy. Nanocarriers (lipid vesicles) targeted to the prostate-specific membrane antigen (PSMA), which is unique to human neovasculature for a variety of solid tumors, were loaded with...
UNLABELLED Prostate-specific membrane antigen (PSMA) is an excellent target for radionuclide therapy of metastasized castration-resistant prostate cancer (mCRPC). Besides high affinity and long tumor retention, the DOTA-conjugated ligand PSMA-617 has low kidney uptake, making it an excellent choice for therapeutic application. We retrospectively report our experience with (177)Lu-PSMA-617-targe...
We investigated the synergism between shRNAs against Bcl-xL and doxorubicin (DOX) using aptamer-conjugated polyplexes (APs) in combination cancer therapy. Synergistic and selective cancer cell death was achieved by AP-mediated co-delivery of very small amounts of DOX and Bcl-xL-specific shRNA, which simultaneously activated an intrinsic apoptotic pathway. A branched polyethyleneimine (PEI) was ...
PURPOSE There is growing evidence that CD4(+) helper T lymphocytes (HTLs) play an essential role in the induction and long-term maintenance of antitumor CTL responses. Thus, approaches to develop effective T-cell-based immunotherapy should focus in the stimulation of both CTLs and HTLs reactive against tumor-associated antigens. The present studies were performed with the purpose of identifying...
Engineered antibody fragments offer faster delivery with retained tumor specificity and rapid clearance from nontumor tissues. Here, we demonstrate that positron emission tomography (PET) based detection of prostate specific membrane antigen (PSMA) in prostatic tumor models using engineered bivalent antibodies built on single chain fragments (scFv) derived from the intact antibody, huJ591, offe...
This paper develops a membrane-inspired evolutionary algorithm, PSMA, which is designed by using a population P system and a quantum-inspired evolutionary algorithm (QIEA). We use a population P system with three cells to organize three types of QIEAs, where communications between cells are performed at the level of genes, instead of the level of individuals reported in the existing membrane al...
Introduction: Accurate staging plays an important role in management of patients with prostate cancer especially in high-risk group. Today, [68Ga]Ga-PSMA-11 PET/CT should be considered as the preferred imaging tool for treatment planning and initial staging of the disease. Methods: A total number of 628 patients with prostate cancer referred to...
Background: By targeting the prostate-specific membrane antigen (PSMA) on prostate cancer (PCa) cells PSMA-PET/CT shows great potential in locating the site of biochemical recurrence even at low PSA (Prostate-specific antigen)-levels. Accurate imaging of PCa recurrent lymph node metastases (LNM) is crucial for metastases directed therapies such as salvage-lymph node dissection (salvage-LND). Ob...
UNLABELLED The expression of prostate-specific membrane antigen (PSMA) is increased in prostate cancer. Recently, (68)Ga-PSMA (Glu-NH-CO-NH-Lys-(Ahx)-[(68)Ga(HBED-CC)]) was developed as a PSMA ligand. The aim of this study was to investigate the detection rate of (68)Ga-PSMA PET/CT in patients with biochemical recurrence after radical prostatectomy. METHODS Two hundred forty-eight of 393 pati...
Context: Gallium prostate-specific membrane antigen (PSMA) ligand Ga-HBED-CC-PSMA (Ga-PSMA) is a promising radiotracer for positron emission tomography (PET)/computed tomography (CT) of prostate cancer. Objective: To conduct a meta-analysis to evaluate detection rate, diagnostic test accuracy, and adverse effects of Ga-PSMA PET/CT or PET/magnetic resonance imaging (MRI) for staging of prostate ...
