Using genomic, transcriptomic and proteomic assays on thyroid cell cultures (PC Cl 3 (PC) and follicular cell line--derived from 18-month-old Fischer rats on Matrigel[R]--, they demonstrated that RET/ PTC3-RAS-BRAF axis acts synergistically to alter thyroid cells (in vitro and in vivo) into an invasive phenotype.
