Publication number: 20110028344Abstract: This patent application discloses and describes a list of proteins that are found to be differentially expressed between normal endometrial epithelial cells and early stage cancerous endometrial epithelial cells. These proteins can be used either individually or in specific combinations in diagnostic and prognostic protein assays on various biological samples from endometrial cancer patients, or individuals suspected on having endometrial cancer. In addition, these proteins are also differentially expressed between normal endometrial epithelial cells and epithelial cells of other types of endometrial disease, and thus such diseases can be diagnosed using assays based on these proteins. The full length intact proteins can be assayed or peptides derived from these proteins can be assayed as reporters for these proteins.Type: ApplicationFiled: April 13, 2009Publication date: February 3, 2011Applicant: Expression Pathology, Inc.Inventors: David B.
