Abstract: The present invention is based, at least in part, upon discovery of a number of miRNAs having expression that significantly correlates with bladder cancer, including certain stages or types of bladder cancer, as well as with bladder cancer survival and/or responsiveness to bladder cancer therapies. Accordingly, the present invention features the identification and use of miRNAs to detect, diagnose and/or predict the course, progression or therapy responsiveness of bladder cancer. Kits for performing such assessments, and for administering therapeutic agents to subjects diagnosed with bladder cancer or certain forms of bladder cancer using the methods of the invention, are also featured.

Abstract: The present invention relates to a method of determining the presence or absence of a biological condition in animal tissue, wherein the expression of genes in normal tissue and tissue from the biological condition is examined and correlated to standards. The invention further relates to the treatment of the biological condition and an assay for determining the condition. More particularly the invention concerns gene expression in epithelial tissue, such as urianry bladder under both normal and abnormal conditions.

Abstract: Methods for analyzing tumor cells, particularly bladder tumor cells employ gene expression analysis of samples. Gene expression patterns are formed and compared to reference patterns. Alternatively gene expression patterns are manipulated to exclude genes which are expressed in contaminating cell populations. Another alternative employs subtraction of the expression of genes which are expressed in contaminating cell types. These methods provide improved accuracy as well as alternative basis for analysis from diagnostic and prognostic tools currently available.

Abstract: The invention concerns a method of determining the presence or absence of a biological condition in humans, in particular of colon cancer, and of determining the stage of a condition in human tissue by determining an expression pattern of a cell sample. Further, the invention relates to a method of determining the presence or absence of a biological condition in human tissue, and of determining the stage of a biological condition in human tissue, and also for reducing biological abnormalities of a cell suffering from the biological condition. A method for producing antibodies against an expression product of a cell from the tissue is also described. The invention also discloses a pharmaceutical composition for the treatment of a biological condition comprising at least one antibody, and a vaccine for the prophylaxis or treatment of a biological condition.
