Figure 6. The promoter role of circCCDC66 in SW1783 and U373 was achieved by regulating miR-320a. (A, B) CCK-8 assays were used to evaluate cell viability. (C, D) Transwell assays were used to detect cell invasion capacities. (E, F) Transwell assays were used to detect cell migration capacities. *P < 0.05, **P < 0.01.
