Provided herein are methods utilizing gene expression profiling and hierarchial clustering analysis to readily distinguish normal ovarian epithelial cells from primary ovarian serous papillary carcinomas. For example, Larninin, tumor-associated calcium signal transducer 1 and 2 (TROP-J IEp-CAM; TROP -2), claudin 3, claudin 4, ladinin I, SI00A2, SERPIN2 (PAl-2), CD24, lipocalin 2, osteopontin, kallikrein 6 (protease M), kallikrein JO, matriptase and stratifin are highly overexpressed genes in ovarian serous papillary carcinomas, whereas transforming growth factor beta receptor HI, platelet-derived growth factor receptor alpha, SEMACAP3, ras homolog gene family, member I (ARHI), thrombospondin 2 and disabled-2/differentially expressed in ovarian carcinoma 2 (Dab2/DOC2) were significantly down- regulated. Also provided are methods of treating ovarian serous papillary carcinoma using the TROP-I /Ep-CAM monoclonal chimeric/humanized antibody. In addition, treatment methods Clostridium Perfringens enterotoxin are provided.

La présente invention concerne des procédés utilisant le profilage de l'expression génétique et l'analyse de classification hiérarchique afin de faire la distinction entre les cellules épithéliales ovariennes normales et les carcinomes papillaires séreux ovariens primaires. Par exemple, la laminine, le transducteur 1 et 2 de signaux calciques associé aux tumeurs (TROP-J IEp-CAM; TROP -2), la claudine 3, la claudine 4, la ladinine I, S100A2, SERPIN2 (PAl-2), CD24, la lipocaline 2, l'ostéopontine, la kallicréine 6 (protéase M), la kallicréine J0, la matriptase et la stratifine figurent parmi les gènes les plus hautement surexprimés dans les carcinomes papillaires séreux ovariens, tandis que le récepteur HI du facteur de croissance transformant bêta, le récepteur alpha du facteur de croissance dérivé des plaquettes, SEMACAP3, la famille génique homologue de ras, le membre I (ARHI), la thrombospondine 2 et un gène 2-déficient/différenciellement exprimé dans un carcinome ovarien 2 (Dab-2/DOC2) sont régulés négativement de manière significative. La présente invention concerne également des procédés de traitement du carcinome papillaire séreux ovarien au moyen de l'anticorps chimère/humanisé monoclonal TROP-I /Ep-CAM. En outre, l'invention a trait à des procédés thérapeutiques utilisant l'entérotoxine Clostridium Perfringens.
