prostate cancer is a devastating disease for which current therapies are inadequate. various lines of evidences have suggested the 5-lipoxygenase (5-lox) pathway and the leukotriene receptor pathway are potential targets for prevention or treatment of prostate cancer. thus, search for new anti-cancer drugs targeting 5-lox and leukotriene is very essential and important. the objective of the pre...

background: in spermatogenesis, spermatogonial cells differentiate to the haploid gametes. it has been shown that spermatogenesis can be done at in vitro condition. in vitro spermatogenesis may provide an open window to treat male infertility. objective: the aim of this study was to evaluate the effects of a novel scaffold containing human serum albumin (hsa)/tri calcium phosphate nanoparticles...

background and aims: during the last years a new foreskin cell line strain (rfsc) has been isolated, characterized and stored in a representative cell bank stock in liquid nitrogen as a part of hcb (human cell bank) development program in razi institute. materials and methods: the cell population was serially passaged for mass production purpose based on who schedule .the controls on pool sampl...

Background: The monoclonal antibody, C595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (Gd-cDTPAa) to produce Gd-DTPA-C595 and used as specific breast cancer cell line (MCF-7) contrast agents in magnetic resonance imaging (MRI).  Methods: After incubation of breast cancer cell line (MCF-7), with different contrast agents (G...

results there were 39 cases with lymph node metastasis in 59 malignant tumors, and 0 cases in 6 benign follicular type tumors. the staining scores by jt-95 of the 39 tumors with lymph node metastasis were 5+ in eight cases and 6+ in 31 cases. on the other hand, the scores of 20 malignant tumors without lymph node metastasis were < 4+ in all of the cases. in the co-cultured assay, numerous adhes...

The lung cancer is one of the most dangerous cancers and is also the leading cause of cancer death worldwide, accounting for about 1.3 million deaths annually. However in clinical practice, lung cancer therapies commonly do with chemotherapy, although it is hard because the lung cancer may progress to metastasis stage. The metastasis of lung cancer is highly dependent of expression of matrix me...

background: as condition and component of culture determine fate map of spermatogonial stem cells (sscs), the aim of this study was to evaluate of growth factors gdnf, lif and ra on proliferation and differentiation of ssc. materials and methods: sscs were cultured in two groups: the first group gdnf and lif and the second group ra. the number of clumps and colony formation was monitored during...

membrane permeability and p-glycoprotein (p-gp) efflux system are regulating factors in the drug brain penetration. recently, some drug delivery systems have been developed to overcome these limitations. in this study, metoclopramid has been encapsulated in plga nanoparticles using the emulsification/solvent evaporation technique for in vitro evaluation of the effect of plga nanoparticles on bb...

Objective(s): Here, a reporter cell line containing two reporter vectors were developed, in order to monitor the Human T-Lymphotropic Virus type1(HTLV-1) infectivity and the cell viability simultaneously. Materials and Methods: The reporter cell line was constructed by stably transfected baby hamster's kidney cell line (BHK-21), with the genomes expressing two different reporters in separate pl...

The objective of the study was to evaluate the cytotoxic effects of aqueous extract of Cucumis melo fruit on human prostate cancer cell line (PC-3) using MTT and neutral red assays. The crude aqueous extract of C. melo was prepared by cold maceration method, filtered, concentrated and tested on PC-3 cell line. Dose-dependent cytotoxic activities were exhibited on human prostate carcinoma PC...
