The HOX genes have been implicated in different aspects of the oncogenic process, as ectopic expression of some HOX genes promotes cellular transformation in vitro and tumorigenesis in vivo. The observation that HOXB13 is expressed in a high percentage of breast and ovarian cancer cell lines and tumors, and that the expression of HOXB13 is associated with a more aggressive clinical course, led us to investigate the ectopic expression of HOXB13 in genetically defined ovarian cancer cell lines. We report identification of several putative HOXB13 targets among which clusterin takes the most prominent role. Clusterin is present in two distinct isoforms, as secreted clusterin (sCLU) and as nuclear clusterin (nCLU). While the former is associated with cell survival, the latter is pro-apoptotic. As a part of the project aiming to identify new therapeutic targets for ovarian cancer, here we describe the generation of clusterinoverexpressing cell lines, representing two contradictory functions of clusterin. These cell lines have subsequently been analyzed using both in vitro and in vivo assays. Consequently, stable ectopic expression of both clusterin isoforms has been demonstrated.
