Abstract Background Bladder cancer is the most common human urological malignancies with poor prognosis, and the pathophysiology of bladder cancer involves multi-linkages of regulatory networks in the bladder cancer cells. Recently, the long noncoding RNAs (lncRNAs) have been extensively studied for their role on bladder cancer progression. In this study, we evaluated the expression of DLX6 Antisense RNA 1 (DLX6-AS1) in the cancerous bladder tissues and studied the possible mechanisms of DLX6-AS1 in regulating bladder cancer progression. Methods Gene expression was determined by qRT-PCR; protein expression levels were evaluated by western blot assay; in vitro functional assays were used to determine cell proliferation, invasion and migration; nude mice were used to establish the tumor xenograft model. Results Our results showed the up-regulation of DLX6-AS1 in cancerous bladder cancer tissues and bladder cell lines, and high expression of DLX6-AS1 was correlated with advance TNM stage, lymphatic node metastasis and distant metastasis. The in vitro experimental data showed that DLX6-AS1 overexpression promoted bladder cancer cell growth, proliferation, invasion, migration and epithelial-to-mesenchymal transition (EMT); while DLX6-AS1 inhibition exerted tumor suppressive actions on bladder cancer cells. Further results showed that DLX6-AS1 overexpression increased the activity of Wnt/β-catenin signaling, and the oncogenic role of DLX6-AS1 in bladder cancer cells was abolished by the presence of XAV939. On the other hand, DLX6-AS1 knockdown suppressed the activity of Wnt/β-catenin signaling, and the tumor-suppressive effects of DLX6-AS1 knockdown partially attenuated by lithium chloride and SB-216763 pretreatment. The in vivo tumor growth study showed that DLX6-AS1 knockdown suppressed tumor growth of T24 cells and suppressed EMT and Wnt/β-catenin signaling in the tumor tissues. Conclusion Collectively, the present study for the first time identified the up-regulation of DLX6-AS1 in clinical bladder cancer tissues and in bladder cancer cell lines. The results from in vitro and in vivo assays implied that DLX6-AS1 exerted enhanced effects on bladder cancer cell proliferation, invasion and migration partly via modulating EMT and the activity of Wnt/β-catenin signaling pathway.

295 Background: Targeted therapies like mTOR inhibition is a clinically esthablished treatment modality for advanced renal cell cancer (RCC). We hypothesize that common elements of molecular signalling exists in RCC and transitional cell carcinoma of the bladder (TCC) that could provide a rational of the usage of this novel compound in human TCC. Therefore the goal of this investigation was to measure the in vivo and in vitro effect of temsirolimus/CCI-779 on human RCC and TCC cell lines on the molecular level. Methods: For in vivo experiments 3 RCC (786-O, A498, ACHN) cell lines and 7 TCC (T24, 5637, RT112, EJ-28, CLS-439, HB-CLS-1, HB-CLS-2) cell lines were compared. Effect of temsirolimus/CCI-779 was measured by real time impedance analysis (XCelligence, Roche). Following mRNA isolation microarray based mRNA expression analysis with 45.015 oligoprobes (G4112F, Agilent Technologies) was performed for molecular comparison of RCC and TCC cell lines. Expression patterns of 15 pathways were analyzed using the statistical software R (2.12.0) and the LIMMA package. Results: RCC and TCC cell lines demonstrated dose dependent inhibition of cellular growth with IC50 values of 10-20nM of temsirolimus/CCI-779 as measured by quantitative real time impedance analysis. Furthermore six out of 15 pathways including the mTOR and VEGF signalling were found with similar expression patterns following treatment with CCI-779 in both tumor entities. Conclusions: In vivo and in vitro analysis of temsirolimus mTOR inhitibtion on human bladder cancer cell lines support the hypothesis that a common molecular architectur exists in both tumor entities suggesting inhibition of mTOR in TCC as a possible target for further experimental therapeutic studies.
