We investigated the molecular mechanisms by which 5-aza-2'-deoxycytidine (DAC) and paclitaxel (PTX) use lymphoid enhancer-binding factor 1 (LEF1) and the Wnt/β-catenin pathway to synergistically interact against renal cell carcinoma (RCC). LEF1 expression was examined by real-time PCR and immunohistochemistry. The regulation of LEF1/β-catenin protein(More)
We evaluated the clinical value of flexible ureteroscopic lithotripsy for the treatment of upper urinary tract calculi in infants. Fifty-five infants with upper urinary tract calculi were included in this study: 41 males and 14 females. Retrograde intrarenal surgery was performed by an 8 Fr/30 cm flexible ureterorenoscope (POLY®) combined with a holmium(More)
BACKGROUND Renal cell carcinoma (RCC) is one of the most common kidney cancers and is highly resistant to chemotherapy. We previously demonstrated that 5-aza-2'-deoxycytidine (DAC) could significantly increase the susceptibility of renal cell carcinoma (RCC) cells to paclitaxel (PTX) treatment in vitro, and showed the synergy of DAC and PTX against RCC. The(More)
The aim of the present study was to investigate the antiproliferative effects of interferon (IFN)-α and rapamycin (RPM) on renal cell carcinoma (RCC) cells and examine the synergistic growth suppression conferred by IFN-α and RPM. The effects of IFN-α and/or RPM on RCC cells were determined using a WST-1 assay and the synergy of IFN-α and RPM against three(More)
PURPOSE To analyse the role of von Hippel-Lindau (VHL) and transforming growth factor β-induced (TGFBI) in synergistic mechanisms of 5-aza-2'-deoxycytidine (DAC) and paclitaxel (PTX) against renal cell carcinoma (RCC). METHODS To elucidate the role in the synergy between DAC and PTX against RCC cells, TGFBI expression was regulated using siRNA technology(More)
Lymphoid enhancer-binding factor 1 (LEF1) has been regarded as an important gene for carcinogenesis in many malignancies, however, the role of LEF1 in the progression of human renal cell carcinoma (RCC) has not been well studied. In this study, we investigated the expression of LEF1 in human RCC and the effect on proliferative ability of RCC cells. RCC(More)
OBJECTIVE The anti-neoplastic effects of decitabine, an inhibitor of DNA promoter methylation, are beneficial for the treatment of renal cell carcinoma (RCC); however, the mechanism of action of decitabine is unclear. We analyzed gene expression profiling and identified specific pathways altered by decitabine in RCC cells. METHODS Four human RCC cell(More)
