Regulation of epithelial plasticity by miR-424 and miR-200 in a new prostate cancer metastasis model
Using an in vivo cycling strategy, we selected metastatic cancer cells from the lymph nodes (LN) of mice bearing orthotopic DU145 human prostate tumors. Repeated rounds of metastatic selection (LN1-LN4) progressively increased the epithelial phenotype, resulting in a new model of tumor cell mesenchymal-epithelial transition (MET). DU145-LN4 showed increased cell-cell adhesions, higher expressio...
Benzo[a]pyrene (B[a]P), a polycyclic aromatic hydrocarbon, is a major environmental pollutant. In this study, the effects of this carcinogen/mutagen and one of its metabolites, benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE), on human prostate carcinoma cell line DU145, were examined. Cell viability, DNA damage, and cell cycle progression were evaluated as toxic end-points. We have shown that B[a]P...
Impaired Ca2+ signaling in prostate cancer contributes to several cancer hallmarks, such as enhanced proliferation and migration and a decreased ability to induce apoptosis. Na+ influx via transient receptor potential melastatin 4 channel (TRPM4) can reduce store-operated Ca2+ entry (SOCE) by decreasing the driving force for Ca2+. In patients with prostate cancer, gene expression of TRPM4 is el...
زمینه و هدف: سرطان پروستات شایع ترین سرطان در جامعه مردان است. عوامل بسیار زیادی منجر به بروز این بیماری می شود. در عین حال فاکتورهای متعددی به منظور پیشگیری و یا درمان این بیماری شناسایی شده اند. آنتی اکسیدان ها و مخصوصاً ترکیبات پلی فنلی مانند اسید گالیک دارای ظرفیت بالقوه ای از این ویژگی هستند. در این مطالعه با استفاده از تکنیک الکتروفورز قلیایی، اثر اسید گالیک را بر لاین سلول های سرطانی Du...
Neutral endopeptidase (NEP) is a cell-surface peptidase that inhibits prostate cancer cell growth partly via inhibition of Akt kinase. We investigated the antitumor effects of an adenovirus gene delivery system (AdNEP) to restore NEP expression in DU145 prostate cancer cells in combination with paclitaxel chemotherapy. DU145 cells were infected with adenovirus expressing NEP or LacZ, treated wi...
Docetaxel has been the standard first-line therapy in metastatic castration resistant prostate cancer. The survival benefit is, however, limited by either primary or acquired resistance. In this study, Du145 prostate cancer cells were converted to docetaxel-resistant cells Du145-R and Du145-RB by in vitro culturing. Next generation RNAseq was employed to analyze these cell lines. Forty-two gene...
Scoparone, a natural compound isolated from Artemisia capillaris, has been used in Chinese herbal medicine to treat neonatal jaundice. Signal transducer and activator of transcription 3 (STAT3) contributes to the growth and survival of many human tumors. This study was undertaken to investigate the anti-tumor activity of scoparone against DU145 prostate cancer cells and to determine whether its...
The aims of this study were to investigate the impact of Soybean Isoflavones (SIFs) on the cellular oxidative stress levels in hormone-sensitive type (LNCap) and hormone-insensitive type (DU145) of prostate cancer, and to elucidate the main components and their roles in the transformation of Androgen Dependency (AD)/Androgen Independency (AI). The LNCap and DU145 cells were treated with differe...
BACKGROUND As one of the most common cancers in men, the pathogenesis of prostate cancer has been widely researched. Aberrant activation of the erb-b2 receptor tyrosine kinase 2 (ERBB2) has been found to play a critical role in metastatic prostate cancer. In our previous study, we demonstrated that rs61552325 (Pro1140Ala) located in ERBB2 is strongly correlated to prostate cancer. Therefore, we...
Activins are growth and differentiation factors which have been shown to have proliferative and antiproliferative actions in many tissues. In addition, they have been implicated in tumourigenesis in reproductive tissues. Although activin and inhibin are present in rat ventral prostate, inhibin beta, but not alpha, subunit proteins have been detected in the human prostate epithelial tumour cell ...
