Fig. 2: Chiauranib induces apoptosis in NKTL cell lines and NKTL xenograft mice.

Annexin V-PI staining of A NKYS and B SNK6 cells exposed to Chiauranib. Cells were treated with Chiauranib, Colchicine (5 μM), and DMSO for 24 h and 48 h, respectively, before staining. C Hoechst staining of NKYS and SNK6 cells treated by DMSO or Chiauranib for 48 h, nucleus fragmentations were as shown. Bar = 50 µm. D, E Representative pictures of tumor tissues and tumor weight of NKTL xenograft mice were measured 3 weeks after inoculation (n = 5 per group). F, G Tunnel assay of mice tumor tissue was performed. Bar = 50 µm.
