Angiogenesis is necessary for the growth, invasion, and metastasis of solid tumors. Previous studies have shown that heme oxygenase-1 (HO-1) plays an important role in angiogenesis in both normal and cancerous cells, such as vascular endothelial cells and pancreatic cancer cells, respectively. In this study, we analyzed the role of HO-1 and other angiogenic factors in urothelial carcinoma of th...
Purpose: The purpose of this study is to evaluate the demethylating and tumor suppressor-reactivating activity of hydralazine and procainamide. Experimental Design: MDA-231, MCF-7, and T24 cell lines were treated for 5 days with 10 M hydralazine or 10 M procainamide. 5-aza-deoxycytidine at 0.75 M was used as positive control. BALB/c nu/nu mice xenografted with MDA-231 cells were treated with th...
Colostrum provides newborn piglets with energy, immunoglobulins and growth, thereby playing an essential role in piglet survival. However, colostrum yield and composition are highly variable among sows. Some of the factors involved in this variability have been identified. The aim of the study was to confirm previous findings on a large number of animals and to investigate other potential facto...
BACKGROUND Increasing evidence has suggested that dysregulation of microRNAs (miRNAs) could contribute to human disease including cancer. Previous miRNA microarray analysis illustrated that miR-320c is down-regulated in various cancers. However, the roles of miR-320c in human bladder cancer have not been well elucidated. Therefore, this study was performed to investigate the biological function...
Growth Inhibition After Exposure to Transforming Growth Factor-β1 in Human Bladder Cancer Cell Lines
PURPOSE Transforming growth factor-β1 (TGF-β1) plays a dual role in apoptosis and in proapoptotic responses in the support of survival in a variety of cells. The aim of this study was to determine the function of TGF-β1 in bladder cancer cells. MATERIALS AND METHODS The role of TGF-β1 in bladder cancer cells was examined by observing cell viability by using the tetrazolium dye (MTT) assay aft...
p27Kip1 is a potent inhibitor of cyclin-dependent kinases that drive G1-to-S cell-cycle transition. Reduced p27Kip1 expression is prevalent in a wide range of human tumours; however, the exact mechanism(s) of p27Kip1-mediated tumour suppression remains obscure. In the present study, we identified a close inverse relationship between p27Kip1 and EGFR (epidermal growth factor receptor) expression...
