Sammanfattning

Progression to metastasis is the proximal cause of most cancer-related mortality. Yet much remains to be understood about what determines the spread of tumor cells. This paper describes a novel pathway in breast cancer that regulates epithelial-to-mesenchymal transition (EMT), motility, and invasiveness. We identify two transcription factors, nuclear factor 1-C2 (NF1-C2) and Forkhead box F1 (FoxF1), downstream of prolactin/nuclear Janus-activated kinase 2, with opposite effects on these processes. We show that NF1-C2 is lost during mammary tumor progression and is almost invariably absent from lymph node metastases. NF1-C2 levels in primary tumors correlate with better patient survival. Manipulation of NF1-C2 levels by expression of a stabilized version or using small interfering RNA showed that NF1-C2 counteracts EMT, motility, invasiveness, and tumor growth. FoxF1 was found to be a direct repressed target of NF1-C2. We provide the first evidence for a role of FoxF1 in cancer and in the regulation of EMT in cells of epithelial origin. Overexpression of FoxF1 was associated with a mesenchymal phenotype, increased invasiveness in vitro, and enhanced growth of breast carcinoma xenografts in nude mice. The relevance of these findings is strengthened by the correlation between FoxF1 expression and a mesenchymal phenoype in breast cancer cell isolates, consistent with the interpretation that FoxF1 promotes invasion and metastasis.
