The cell lines were derived from a follicular adenoma (KAK-1), two follicular carcinomas (MRO-87 and WRO-82), two papillary carcinomas (NPA87 and KAT-10), and four anaplastic thyroid carcinomas (DRO-90, ARO-81, KAT-4, and KAT-18).
In the present study, we identified a missense mutation (G199V) in KAT-18 cell line established from primary cultures of anaplastic thyroid cancer (ATC).
The quantitative real-time polymerase chain reaction and immunohistochemistry analyses showed that downregulation of JAM-A occurred in anaplastic thyroid carcinoma (ATC) compared with normal thyroid (NT) and papillary thyroid carcinoma (PTC) tissues and correlated with extrathyroid infiltration, tumor size, and ATC histotype.
