In this study, we report an active targeting liposomal formulation directed by a novel peptide (RGD) that specifically binds to the integrins receptors overexpressed on prostatic cancer cells. The objectives of this study were to evaluate the in vitro and in vivo tumor drug targeting delivery of RGD modified liposomes on PC-3 cells and DU145 cells. The uptake efficiency of RGD-LP was 5.2 times ...
Combination effects of docetaxel (DOC) and doxorubicin (DOX) were investigated in prostate cancer cells (PC3 and DU145). Combination indices (CIs) were determined using the unified theory in various concentrations and mixing ratios (synergy: CI < 0.9, additivity: 0.9 < CI < 1.1, and antagonism: CI > 1.1). DOC showed a biphasic cytotoxicity pattern with the half maximal inhibitory concentration ...
Background: Previously, we showed that AG2034, an inhibitor of glycinamide ribonucleotide formyltransferase (GARFT) in the pathway for de novo purine synthesis, is cytotoxic to different prostate cancer cell lines in the absence of inosine and hypoxanthine in the culture media. Therefore, we examined DU145 androgenindependent prostate cancer cells selected for drug resistance over a prolonged p...
Background: Radiotherapy is an established therapeutic modality for prostate cancer. Resveratrol, a natural antioxidant, has been shown to inhibit carcinogenesis and to block the process of tumor initiation and progression. No data is available on the response of cellular spheroid to Reseveratol. In this study we have examined the effect of Resveratol on the radiation response of human p...
Background: Prostate cancer is one of the leading causes of cancer deaths among men. New gene expressed in prostate (NGEP), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. Because of its selective expression in prostate cancer cell surface, NGEP is a potential immunotherapeutic target. To target the NGEP in prostate cancer, it is essential to investig...

background: the purpose of this study was to investigate the enhanced thermal resistance mechanism of the du145 tumor spheroid cultures as compared to the prostate carcinoma cell line's monolayer cultures. materials and methods: du145 cells were cultured either as spheroids or monolayers. cultures were treated with hyperthermia in a precision water bath (at 43°c for 60 minutes) and/or quercetin...
Advanced prostate cancer is difficult to treat due to androgen resistance, its deep location and blood tumor barriers. Low-frequency ultrasound (LFU) has potential clinical applications in the treatment of prostate cancer due to its strong penetrability and high sensitivity towards tumor cells. Simvastatin has often been administered as a preventive agent in prostate tumors. The aim of the pres...
