background: nowadays, highly specific aptamers generated by cell selex technology (systematic evolution of ligands by exponential enrichment) are being applied for early detection of cancer cells. prostate specific membrane antigen (psma), over expressed in prostate cancer, is a highly specific marker and therefore can be used for diagnosis of the prostate cancer cells. the aim of the present s...

Cancers cells change their mechanical properties to migrate through crowded multicellular environments. Metastatic cells’ traction forces have been shown increase substantially relative those of non-metastatic cells, and this contractility is further increased by matrix stiffening, promoting tumor phenotypes. These findings suggest a relationship between cell contractility, microenvironment sti...

Objective(s): Apoptotic effect of apoptin has been demonstrated in numerous studies. However, its tumor specificity has been questioned by some reports. The aim of this study was to confine the expression of apoptin in the prostate tumor cells by inducing its gene expression under the control of a chimeric enhancer composing of prostate-specific membrane antigen (PSMA) and prostate-specific ant...

Androgen deprivation therapy (ADT, surgical or chemical castration) is the mainstay treatment for metastatic prostate cancer (PCa); however, patients ineluctably relapse despite extremely low androgen levels. This evolution of PCa indicates its lethal progression. In this study, to mimic the traits of clinical PCa progression in vitro, we investigated the alterations in the cell biological char...

Antiproliferative protein (APP) isolated from conditioned media of two androgen-independent prostatic carcinoma cell lines, PC3 and Du-145 was shown to inhibit selectively cell proliferation of androgen-dependent prostate cancer cell line LNCaP in a dose dependent manner. This protein was further purified with HPLC using hydrophobic interaction column (phenyl 5PW) and was used to study the modu...

Background: Prostate cancer is the second most common cancer in men worldwide and the third most common cancer in Iranian men. Chemotherapy is used to treat this cancer, but it has toxic effect. Natural compounds found in marine organisms and plants have anticancer considered. The aim of the present study was to investigate the effect of crab shell extract on induction of apoptosis in prostate ...

Objective: In an earlier study, we obtained androgen-independent prostate cancer cells (LNCaP-AI) and flutamide tolerantLNCaP-AI (LNCaP-AI+F cells) that could survive in an androgen-free environment without or with flutamide, respectively. In the present study, we investigated the molecular mechanism of the castration resistance. Material and Methods: qRT-PCR was applied to measure the expressi...

objective: prostate cancer antigen 3 (pca3) and microrna-141 (mir-141) are emerging molecules in prostate cancer (pca) pathogenesis and have been shown to be involved in androgen signaling. in this original research, we designed an experimental cell model with androgen-sensitive lncap cells to comparatively assess the extent of androgen responsiveness of pca3-mrna and mir-141 along with prostat...

PURPOSE The levels of interleukin-6 (IL-6) are frequently elevated in sera from patients with advanced prostate carcinoma. Our main objective was to investigate changes in responsiveness to IL-6 and/or androgen that occur in LNCaP cells after long-term treatment with IL-6. This in vitro model could be of clinical relevance because of its similarity with late-stage prostate carcinoma. EXPERIME...

Background . Melittin is a major constituent of honeybee venom and comprises water-soluble surfactant peptide with cytolytic effects potentially applicable in anticancer therapy. We evaluated the impact melittin from Bashkir ( Apis mellifera L.) on cell viability various prostate cancer lineages. Materials methods. MTT assays index estimation were used to evaluate effect proliferation various-g...
