Figure 2. Knockdown of circ0060467 suppresses HCC tumor growth. (A) si-circ0060467 successfully knocked down circ0060467 in 7402 (left) and 97H (right) cells. (B) Cell Counting Kit-8 assay was performed to evaluate cell proliferation in 7402 and 97H cells. (C) Tumor volume was measured every 4 days for 4 weeks. (D) Expression status of Ki67 in hematoxylin-eosin-stained sections of harvested xenograft tumors. **p < 0.01.
