The blast stem cells of acute myeloblastic leukemia (AML) respond in cell culture to growth factors by both self-renewal and terminal divisions. Both of these functions have been shown to be stimulated by the recombinant growth factors granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF). In this paper, recombinant gibbon interleukin-3 (IL-...
Despite widespread application of cisplatin in treatment of transitional cell carcinomas, its efficiency is far from satisfactory due to acquired drug resistance. The present study was carried out to estimate the effects of conferone, a sesquiterpene-coumarin isolated from Ferula badrakema, on increasing cisplatin cytotoxicity in 5637 cells. In order to determine conferone effects, 5637 cells w...
The limited success of IFN-alpha therapy for clinical treatment of transitional cell carcinoma (TCC) has prompted us to investigate the responsiveness of TCC lines to IFN-alpha. The response to IFN-alpha in terms of 561 gene induction, an IFN-stimulated response element-containing IFN-alpha/beta-inducible gene, and IFN-stimulated gene factor 3 (ISGF3) formation was normal in primary human uroth...
هدف از انجام این مطالعه بررسی چگونگی اثر tgf-b2 بر بیان ژن gm-csf انسانی می باشد. (gm-csf) granulocyte- macrophage colony stimulating factor قادر به تحریک پدیده تمایز در سلولهای مادری خونساز بوده و فعالیت سلولهای بالغ خونی را تحت تاثیر قرار می دهد. از این جهت همیشه بعنوان یک عامل مهم در پدیده خونسازی مورد توجه بوده است. سلولهای 5637 بدلیل افزایش نیمه عمر رونوشتهای (mrna) و بیان...
شیمی درمانی رایج ترین و قدیمی ترین روش درمان سرطان بوده، که در آن درمان با استفاده از داروهای مختلفی از جمله ترکیبات گیاهی صورت می گیرد. پودوفیلوتوکسین یکی از ترکیبات گیاهی است که دارای خواص بیولوژیکی مختلفی از جمله خاصیت ضد توموری است. این ترکیب در آب نامحلول بوده و دارای سمیت زیادی است، به همین دلیل مشتقات زیادی از آن ساخته شده، که در آب محلول هستند. 6متوکسی پودوفیلوتوکسین یکی از مشتقات پودوف...
Chemoresistance prevents the curative cancer therapy, our understanding of which remains inadequate. Among the differentially expressed genes between the chemosensitive (5637) and chemoresistant (H-bc) bladder cancer cell lines, the expression level of the PSEN1 gene (presenilin 1), a key component of the γ-secretase, is negatively correlated with chemoresistance. A small interfering RNA mediat...
Transient receptor potential vanilloid 2 (TRPV2), a nonselective cation channel, has become an attractive target gene for tumor studies due to its wide range of physiological and pathological functions. However, its specific role in bladder cancer development and progression remains unclear. The aim of the present study was to investigate the effects of TRPV2 on the proliferation, migration and...
Natural products continue to be an invaluable resource of anticancer drug discovery in recent years. Propolis is known for its biological activities such as antimicrobial and antitumor effects. This study assessed the effects of Brazilian red propolis (BRP) on apoptosis and migration potential in human bladder cancer cells. The effect of BRP ethanolic extract (25, 50, and 100 μg/mL) on 5637 cel...
MicroRNAs (miRNAs) have been demonstrated to be involved in the development of numerous types of malignant tumor. However, the role of miRNA-430 (miR-430) in bladder cancer remains unclear. In the present study, we observed that the expression of miR-430 was significantly downregulated in bladder cancer. Furthermore, the overexpression of miR-430 in human bladder cancer 5637 cells significantly...
The aim of the present study was to investigate the effects of Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA) on inhibiting the proliferation of bladder cancer cell lines and to further define its functional mechanisms. T24 and 5637 cells were treated with PA-MSHA at various concentrations and times. Cell proliferation was analyzed using Cell Counting Kit-8 (CCK-8) assays. The...
