Overcoming the lack of expression of the sodium-iodide symporter protein in anaplastic thyroid cancer stem cells by targeting the phosphatidyl inositol 3-kinase signaling pathway
Background: Anaplastic thyroid carcinoma (ATC) is rare, but it is the most aggressive thyroid cancer. Cancer stem cells (CSCs), which have self-renewal ability and can generate multi-lineage cells, are potential causative agents for ATC recurrence. To assess the role of CSCs in ATC, we evaluated the sodium-iodide symporter (NIS or SLC5A5) and Phosphatidyl Inositol 3-Kinase (PI3K) mRNA levels in the (CD133pos) CSC fraction of ATC cell lines. Methods: Using magnetic cell sorting, we isolated (CD133pos) CSCs from three ATC cell lines.
