Figure 7. TTK promotes PTC cell invasion and migration. (A) The invasion of TPC1 and BCPAP cells transfected with shNC or shTTK and control for 24 h was measured by transwell invasion assay. (B) The migration of two PTC cells was assessed by wound-healing assay. Western blot for (C) metastasis-related proteins and (D) EMT maser genes in TTK-knockdown TPC1 and BCPAP cells. Compared with shNC, **P < 0.01.
