Figure 2. Knockdown of DLG1-AS1 inhibited cell viability and invasion of PTC cells. (A) The expression of DLG1-AS1 is downregulated in TPC-1 cells transfected with sh-DLG1-AS1 or sh-NC. (B–E) Knockdown of DLG1-AS1 inhibits proliferation, colony formation, migration, and invasion in TPC-1 cells transfected with sh-DLG1-AS1 or sh-NC. All experiments were performed in triplicate, and data are expressed as mean ± standard deviation (SD) (*P < 0.05, **P < 0.01).
