Human thyroid cancer cell line that expresses the RET/PTC1 rearrangement


CU researchers have developed a human thyroid cancer cell line that expresses the RET/PTC1 rearrangement. The cell line, called CUTC48, was derived from a 68-year-old female patient with metastatic papillary thyroid cancer (PTC). CUTC48 cells do not form flank tumors in mouse models but do express high levels of the RET/PTC1 transcript and protein. This cell line creates a cultured cell model that contains a common genetic alteration in papillary thyroid cancer and can be used to investigate mechanisms thyroid cancer studies and new therapeutic strategies for the disease.
