Gene expression profiling in primary ovarian serous papillary tumors and normal ovarian epithelium

摘要

Provided herein are methods for treating ovarian serous papillary carcinoma by delivering Clostridium perfringens enterotoxins to ovarian tumor cells overexpressing claudin 3 or claudin 4 protein or by inhibiting the expression and function of tumor-associated calcium signal transducer 1 (TROP-1/Ep-CAM) gene or gene product. Also provided is a method of detecting ovarian serous papillary carcinoma by examining a tumor sample from the individual for gene or gene product expression levels within a group of genes and performing statistical analysis to determine those genes or gene products which are down-regulated compared to those in a normal individual.
