High-throughput retroviral tagging to identify genes and signaling pathways cooperating with BRAF in thyroid carcinogenesis

Activation of oncogene alone is usually insufficient to transform epithelial cells. For PTCs driven by mutant BRAF we attempted to reveal the additional genetic abnormalities that are required to confer malignant phenotype on cancer cells. For this purpose, as a model, we performed retrovirus insertional mutagenesis in doxycycline-inducible BRAFV600E-expressing clonal lines derived from rat thyroid PCCL3 cells, and picked the clones that do not require TSH for growth. By PCR-based splinkerette procedure and microarray analysis we have successfully identified several possible candidate genes (Trpm1, Nek6, etc).
