قرن هاست که از شیمی درمانی برای درمان سرطان استفاده می شود. داروها و ترکیبات مختلفی در شیمی درمانی استفاده می شود که هر کدام برای نوع خاصی از سرطان استفاده می شود. در این بین ترکیبات گیاهی از جمله لیگنان ها، مدت هاست که در پزشکی و داروسازی مورد استفاده قرار می گیرند. پودوفیلوتوکسین یکی از اعضای خانواده لیگنان ها بوده که عمدتا از گونه های جنس Podophyllum استخراج می شود. این ترکیب دارای خواص بیو...
Since cancer cells are characterised by multiple genetic alterations the single inhibition of one tumour- associated gene might not be sufficient as a therapeutic strategy. We examined the effects of a combined inhibition of survivin, human telomerase reverse transcriptase (hTERT) and vascular endothelial growth factor (VEGF) with antisense oligodeoxynucleotides (AS-ODNs) and small interfering ...
Bladder cancer is one of most common malignant cancer. Although previous studies have found abnormal expression of B7-H3 in human bladder cancer tissues, the exact role and molecular mechanism of B7-H3 in bladder cancer remain unknown. In this study, we first detected the expression of B7-H3 in human bladder cancer samples and cell lines, and analyzed its correlations with clinicopathological p...
Mediator complex subunit 19 (Med19), a RNA polymerase II-embedded coactivator, is reported to be involved in bladder cancer (BCa) progression, but its functional contribution to this process is poorly understood. Here, we investigate the effects of Med19 on malignant behaviours of BCa, as well as to elucidate the possible mechanisms. Med19 expression in 15 BCa tissues was significantly higher t...
Human multipotential and committed hematopoietic progenitor cells require the presence of specific glycoproteins, termed "colony-stimulating factors" (CSFs) for survival, clonal proliferation, and differentiation. Recently, a pluripotent G-CSF, constitutively produced by the human bladder carcinoma line 5637, has been purified to apparent homogeneity [11 and molecularly cloned with the compleme...
Human intraepithelial lymphocytes (IEL), predominantly CD8+ T-lymphocytes located between intestinal epithelial cells (EC), may represent the first-line immune defense against colon cancer. The mechanism by which IEL bind to the colon cancer line, DLD-1, was evaluated. A larger fraction of IEL than peripheral blood mononuclear cells bound to DLD-1 monolayers (25 +/- 16 versus 8 +/- 4% binding, ...
OBJECTIVE To evaluate the influence of Everolimus (RAD001) on chemically induced urothelial lesions in mice and its influence on in vitro human bladder cancer cell lines. METHODS ICR male mice were given N-butyl-N-(4-hydroxybutyl) nitrosamine in drinking water for a period of 12 weeks. Subsequently, RAD001 was administered via oral gavage, for 6 weeks. At the end of the experiment, all the an...
The level of granulocyte-macrophage colony-stimulating factor (GM-CSF) mRNA is fourfold lower in phorbol myristate acetate (PMA) + phytohemagglutinin (PHA)-activated mononuclear cells (MNC) from newborns compared with adults. The GM-CSF transcription rate is similar in umbilical cord and adult MNC, but transcript half-life is threefold lower in cord activated MNC. Interaction of RNA binding pro...
