Diagnosing and Treating Cancer Using Beta-Catenin Splice Variants Description of Technology: This application discloses and claims inventions which may be used alone or together. One group of inventions relates to early detection diagnostic, prognostic and patient monitoring methods (``Diagnostic Methods''). The other group of inventions relates to methods of treatment. Both groups of inventions have particular application with respect to esophageal squamous cell cancers (ESCC) or other types of adenocarcinomas and squamous cell carcinomas. The Diagnostic Methods are useful in evaluating the status of preneoplastic lesions as well as tumor tissue. Because of this, the methods can be used to track the progression or regression of disease in many types of cell samples from normal to dysplasia to cancer. The Diagnostic Methods involve measuring the level of one or more pairs of transcripts or the protein products of these pairs of transcripts or the cellular localization of the transcripts or proteins. The primary transcripts or protein products useful in this method are those of the beta-Catenin gene (CTNNB1). In particular, the levels of the 16A and 16B CTNNB1 transcripts or protein products are of importance in carrying out the methods of this patent application. Other gene transcripts or protein products that may be used in conjunction with CTNNB1 16A and 16B to provide additional information are WAF1 (p21) and cMYC. The treatment methods include employing small interfering RNA molecules (siRNAs) as a means to alter the expression of one or more of these particular CTNNB1 transcripts. More specifically, preferred siRNA molecules can be used to alter the expression of the CTNNB1 transcripts 16A and/or 16B. These siRNA molecules may be single-stranded (ss) or double-stranded (ds) and may be delivered using a construct capable of producing the siRNA molecule upon delivery to the target cell. Applications: Diagnostic or prognostic methods for squamous cell cancers and adenocarcinomas; Monitoring therapeutic response during and after patient treatment; Development of cancer treatments; Basic research to further elucidate the role of beta catenin in signal transduction pathways and carcinogenesis. Development Stage: The use of beta catenin transcripts to provide prognostic or diagnostic information remains the subject of research but early patient data is found in the article in Genes Chromosomes & Cancer listed below. Work related to the use of siRNA as a treatment strategy remains in its early stages of research and has not yet progressed to clinical trials. Inventors: Mark J. Roth and Konrad Huppi (NCI).
