Figure 5. Effect of TTK on PTC cell growth. TTK knockdown efficiency of cells transfected with scrambled shRNA (shNC) or shRNAs against TTK (shTTK) for (A, B) 24 h and (C, D) 48 h in TPC1 and BCPAP cells. (E) The viability of TPC1 and BCPAP cells following TTK knockdown. (F) Representative images (up) and quantification (down) of colony formation assays of two cells. Compared with shNC, *P < 0.05, **P < 0.01; compared with shTTK-1, #P < 0.05, ##P < 0.01.
