Background: Rad51 is a protein with critical role in double strand break repair. Down-regulation of this protein has a significant effect in radiosensitivity of some cell lines like prostate carcinoma. Compared to monolayer cell culture model, the spheroids are more resistant to radiation. The aim of the current study was to determine the Rad51 protein level in DU145 spheroids, and monol...

background: prostate specific antigen (psa) has been used as a screening test for the early detection of prostate cancer (pc) for many years. although the introduction of psa test led to a considerable increase in reported prostate cancer cases, there is still some controversy over the sensitivity and specificity of this marker in distinguishing pc patients from those with benign prostate hyper...

Cancer metastasis is the process of dissemination cancer cells from their original site and localization in distant sites. During this journey, metastatic have to undergo several phenotypical/ genotypical changes for acquiring cell migration, invasion, attachment properties etc. These steps can be partially/fully mimicked under vivo vitro conditions. Here, we injected prostate line, DU145, into...

the purpose of this study is to investigate the effects of quercetin as an inhibitor of heat shock proteins and hyperthermia on the induced dna damages and colony formation ability of du145 tumor spheroid culture. du145 cells were cultured as spheroids. on day11, spheroids with mean diameter 100 μm were treated with different concentration of quercetin for 24 hours and then exposed to hyperther...

Background: Radiotherapy and adjuvant androgen deprivation therapy have historically been the first treatment choices for prostate cancer but treatment resistance often limits the capacity to effectively manage the disease. Therefore, alternative therapeutic approaches are needed. Here, the efficacies of radiotherapy and targeting the pro-survival cell signaling components epidermal growth fact...

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-3 c...

Bu(3)SnH/1,1'-azobis(cyclohexanecarbonitrile) (ACN)-mediated five, six, and seven-membered double alkyl radical cyclizations onto imidazo[5,4-f]benzimidazole and imidazo[4,5-f]benzimidazole are described. The quinone derivatives evaluated show selective toxicity towards human cervical (HeLa) and prostate (DU145) cancer cell lines (with negligible toxicity towards a normal human cell line, GM006...

OBJECTIVE Despite various therapeutical options in metastatic prostate cancer, the lack of a curative approach motivates further investigations. Treosulfan is an alkylating agent that has proven its indication in the treatment of e.g. ovarian carcinoma. This study focused on the objective of evaluating the effect of in vitro intoxication of human prostate carcinoma cell lines with treosulfan. ...

AIM Epidermal growth factor receptor (EGFR) is a novel molecular target for anticancer therapy. This study examined the effects of anti-EGFR antibody cetuximab on two human androgen-independent prostate carcinoma cell lines, Du145 and PC-3. MATERIALS AND METHODS Cell proliferation was monitored with a trypan blue viability assay. Cell apoptosis and cell cycle profile was evaluated by flow cyt...
