Quantification of Cell Migration and Invasion, and Their Association with Periostin in Anaplastic Thyroid Cancer, Using a Real-time Cell Analyzer

Abstract

: Anaplastic thyroid cancer ATC is known to be a highly malignant cancer of the thyroid with a high mortality rate. In a previous study, we used realtime cell analysis RTCA to analyze cell migration and invasion of oral squamous cell carcinomas OSCCs of the tongue and oor of the mouth. In the present study, we investigated cell migration and invasion of ATC using RTCA, as well as their association with periostin, matrix metalloproteinases MMPs , and integrins. Experiments were performed on TCO-1 and HTC / C3 cells, which are human ATC cell lines. OSCC cell lines were used for comparison. Using the cell analysis system, cell migration was assessed on bronectin-coated CIM-Plates, whereas invasion was assessed on fibronectin-and matrigel-coated CIM-Plates. SCC-4 cells exhibited high cell migration and invasion activity compared with other OSCC cell lines. TCO-1 cells exhibited equivalent cell invasion but stronger migration than SCC-4 cells. Although TCO-1 cells had strong invasive activity, they did not express MMP-9, unlike SCC-4 cells. Conversely, periostin expression was high in TCO-1 cells. Therefore, periostin expression appears to be associated with the cell migration and invasion activity of ATC. The RTCA system will be useful for the analysis of the metastatic characteristics of ATC in head and neck cancer.

“…In particular, EGCG inhibited TCO-1 cell adhesion and proliferation. The ndings of the present study show that at 10 .…”

“…In a previous study using RTCA we showed that EGCG inhibited cell migration and invasion in oral squamous cell carcinomas OSCCs 9 . Moreover, we have demonstrated that anaplastic thyroid cancer ATC cells TCO-1 have high migratory and invasive activity in association with high periostin expression 10 . In particular, TCO-1 cells exhibit very high periostin expression compared with other cell lines tested 10 .…”
