Figure 2. TNFSF9 knockdown inhibits the proliferation of pancreatic cancer cells and promotes the apoptosis of pancreatic cancer cells. (A, B) Cell counting kit-8 was used to evaluate the proliferation of BXPC-3 and PANC-1 cells after TNFSF9 knockdown. (C–F) Colony formation was used to analyze the proliferation of BXPC-3 and PANC-1 cells after TNFSF9 knockdown. (G–J) Flow cytometry was used to analyze the apoptosis of BXPC-3 and PANC-1 cells after TNFSF9 knockdown. *P < 0.05, **P < 0.01, and ***P < 0.001.
