Figure 3. PTTG3P promotes CC growth through increase in cell proliferation. (A-B) The effects of PTTG3P on the growth of Ca-Ski cells (A) and HTB31 (B) were assessed in an CCK-8 assay. (C-D) BrdU assay was used to measure cell proliferation, shown by quantification (C), and by representative images (D). (E-F) TUNEL assay was used to measure cell apoptosis, shown by quantification (E), and by representative images (F). *p<0.05 (versus SCR). NS: non-significant. N=5. Scale bars are 20µm.
