background: oct4b1, a novel variant of oct4, is expressed in cancer cell lines and tissues. based on our previous reports, oct4b1 appears to have a crucial role in regulating apoptosis as well as stress response [heat shock proteins (hsps)] pathways. the aim of the present study was to determine the effects of oct4b1 silencing on the expression of high molecular weight hsps in three different h...

BACKGROUND Sirolimus is recently reported to have antitumour effects on a large variety of cancers. The present study was performed to investigate sirolimus's ability to inhibit growth in T24 bladder cancer cells. METHODS T24 bladder cancer cells were treated with various concentrations of sirolimus. MTT assay was used to evaluate the proliferation inhibitory effect on T24 cell line. The viab...

objective: podophyllotoxin (ptox), a natural compound in numerous plants, contains remarkable biological properties that include anti-tumor, anti-viral such as anti-human immunodeficiency virus (hiv) activities. in order to avoid its adverse effects, various compounds have been derived from ptox. 6-methoxy ptox (mptox) is one of the natural ptox derivatives with an extra methoxy group. mptox is...

objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...

The high frequency of recurrence and poor survival rate of bladder cancer demand exploration of novel strategies. Biotherapy strategies include immunotherapy, gene therapy, inducing cell apoptosis, and so on. Precious studies indicated that BCG could effectively prevent tumor recurrence, and significantly reduce tumor progression. Our studies showed that BCG combined with epirubicin S59 Transla...

Although the effects of sanguinarine, a benzophenanthridine alkaloid, on the inhibition of some kinds of cancer cell growth have been established, the underlying mechanisms are not completely understood. This study investigated possible mechanisms by which sanguinarine exerts its anticancer action in cultured human bladder cancer cell lines (T24, EJ, and 5637). Sanguinarine treatment resulted i...

Bladder cancer is the fifth most common cancer with significant morbidity and mortality. Recently, numerous studies demonstrated that microRNAs are emerging as diagnostic biomarkers for bladder cancer. Specific miRNA profiles have been identified for several samples from patients with bladder cancer. MicroRNAs are noncoding RNA molecules of approximately 23 nucleotides that play important roles...

bladder cancer is the fifth most common cancer with significant morbidity and mortality. recently, numerous studies demonstrated that micrornas are emerging as diagnostic biomarkers for bladder cancer. specific mirna profiles have been identified for several samples from patients with bladder cancer. micrornas are noncoding rna molecules of approximately 23 nucleotides that play important roles...

The oncogenic isoform of the p63 protein, delta Np63 (delta Np63), plays an important role in the pathogenesis of many epithelial carcinomas, and emerging evidences suggest that delta Np63 is a promising drug target. However, the functions of delta Np63 in transitional cell carcinoma of bladder (TCCB) are poorly defined. In this study, a delta Np63 shRNA expression vector was transfected into T...
