Stromal Interaction Molecule 1 (STIM1) Knock-down Attenuates Migration and Proliferation and Enhances the Expression of Thyroid Specific Proteins in Human Follicular Thyroid Cancer Cells.
Abstract:Stromal interaction molecule 1 (STIM1) and the ORAI1 calcium channel mediate store-operated calcium entry (SOCE) and regulate a multitude of cellular functions. The identity and function of these proteins in thyroid cancer remained elusive. We show that STIM1 and ORAI1 expression is elevated in thyroid cancer cell lines, compared with primary thyroid cells. Knock-down of STIM1 or ORAI1 attenuated SOCE, reduced migration, and expression of promigratory sphingosine 1-phosphate (S1P) and vascular endothelial grow… Show more
