Uroplakins (UPs) are a group of integral membrane proteins that are synthesized as the major differentiation products of mammalian urothelium. UPII gene expression is bladder specific and differentiation dependent, but very little is known about its transcription response elements. To identify the promoter elements, a DNA fragment of 2239 bp upstream of the(More)
PURPOSE The purpose of this study was to examine the tumor specificity, cytotoxicity, and granulocyte macrophage colony-stimulating factor expression of CG0070, a conditionally replicating oncolytic adenovirus, in human bladder transitional cell carcinoma (TCC) cell lines and determine its antitumor efficacy in bladder TCC tumor models. EXPERIMENTAL(More)
Retroviral vectors are commonly used in ex vivo gene therapy protocols. The structure of vectors basically consists of one gene of interest and a selectable marker gene. Fast selection without damaging cells is a critical step for ex vivo gene therapy protocols. Blasticidin S deaminase isolated from Bacillus cereus has a neutralizing action on the highly(More)
Radiation is an effective means of treating localized prostate cancer. However, up to 40% of men with certain risk factors will develop biochemical failure 5 years after radiotherapy. CV706, a prostate cell-specific adenovirus variant, is currently in clinical trials for the treatment of recurrent organ-confined prostate cancer. We demonstrated previously(More)
Adenovirus has been used widely as a gene transfer vector in the laboratory and clinic for the purpose of gene therapy. Conditionally replication-competent oncolytic adenoviruses are capable of multiplying up to a thousand old in target cells, a property that might prove to be of tremendous potential in the area of cancer therapy. Intravesicular therapy of(More)
The use of adenovirus type 5 (Ad5) for cancer therapy is limited by deficiency of its primary cell attachment receptor, coxsackie and adenovirus receptor (CAR), on cancer cells. Ad5 retargeting to alternate receptors through fiber genetic modification can be used to circumvent CAR dependence of its tropism, and thereby achieve infectivity enhancement. Here(More)
A model based two-dimensional object recognition system capable of performing under occlusion and geometric transformation is described in this paper. The system is based on the concept of associative search using overlapping local features. During the training phase, the local features are hashed to set up the associations between the features and models.(More)
