Objective: To investigate the role of TGF-β1 on Epithelial Mesenchymal Transition (EMT) and invasion ability in human bladder cancer cell line T24. Methods: After pre-treatment with TGF-β1 of different concentrations for 24 h, we observed the morphological changes of T24 cells under phase-contrast microscopy. The mRNA and protein expression levels of EMT relative marker E-cadherin and Vimentin ...

Because of difference in the toxicokinetic and pharmacokinetic characteristics of drugs and with respect to the high rate of benzodiazepine abuse in suicidal attempts, the trend of possible anterograde amnesia after recovery from benzodiazepine overdose were evaluated in Iranian patients. This was a prospective descriptive/analytic clinical trial, which was conducted, in Noor general teaching h...

Bladder cancer has been cited to result from the neoplastic lesion with environmental and/or occupational factors identified as causatives. Transitional cell carcinoma (TCC) is the most common type of bladder cancer. Most of the bladder cancer patients die from the invasive, metastatic TCC that has turned out to be resistant to chemotherapy. T24 cells, a cell line established from a human urina...

Clinical results of current intravesical chemotherapeutics are insufficient, and novel and safe intravesical options for high-risk bladder cancer are required to prevent both recurrence and progression. In this study, we show promising efficacy of intravesical combination treatment using antisense oligonucleotides targeting heat shock protein-27 (Hsp27; OGX427) with HTI-286, a synthetic analogu...

OBJECTIVE 18F-fluoromisonidazole (FMISO), a well-known PET imaging probe for diagnosis of hypoxia, is believed to accumulate in hypoxic cells via covalent binding with macromolecules after reduction of the nitro group. Previously, we showed the majority of 18F-FMISO was incorporated into low-molecular-weight metabolites in hypoxic tumors, and the glutathione conjugate of reduced FMISO (amino-FM...

To investigate the biological function of microRNA-34a (miR-34a) in bladder cancer, the expression of miR-34a was determined using quantitative real-time polymerase chain (qRT-PCR) reaction in 42 cases of bladder cancer. The relationship between the expression of miR-34a and development of bladder cancer was also studied. The mature mimics of miR-34a were chemically synthesized and transiently ...

BACKGROUND Bladder cancer is a major widespread tumor of the genitourinary tract. Around 30% of patients with superficial cancers develop invasive and metastatic pathology. MATERIAL AND METHODS Some new heterocyclic 4-methyl coumarin derivatives were designed using molecular modeling studies to evaluate their potential against bladder cancer lines T24 and RT-4. The designed compounds that showe...

We hypothesized that Escherichia coli cytotoxic necrotizing factor 1 (CNF1) might impair migration or proliferation of bladder cells and could potentially interfere with repair of the bladder epithelium. Using experimentally wounded human T24 bladder epithelial cell monolayers as an in vitro model, we found that both the number of T24 cells and the maximum distance they migrated into wounded re...

The inhibition effect of brazilin to human bladder tumor cell line T24 in vitro and in vivo was studied. The results of the in vitro experiments showed that brazilin has strong inhibition activity on the target cells. The inhibition ratio of 100 μg/mL brazilin and 100 μg/mL mitomycin to the target cells was 90.90 % and 63.24 % respectively, which showed that brazilin has higher inhibition activ...

OBJECTIVE To evaluate retinol concentration in colostrum samples collected with a 24 hour interval. METHOD Colostrum was collected from 24 recently-delivered mothers at two points in time, 0 hours (T0) and 24 hours later (T24), and a pooled sample of colostrum from T0 and T24 was also analyzed. Fat content was determined by creamatocrit, and retinol assayed by high performance liquid chromato...
