Figure 3. circIFI30 promotes TNBC cell proliferation. (A) Relative expression of circIFI30 was determined in TNBC cells transfected with circIFI30 expression vector, mock, sh-circ or sh-NC by qRT-PCR. (B) The cell viability was measured in TNBC cells transfected with indicated vectors by CCK-8 assay. (C, D) The cell proliferation ability was detected in TNBC cells after transfection with indicated plasmids by EdU assay. Scale bar, 50 μm. (E, F) Cell survival was evaluated in TNBC cells transfected with indicated plasmids by colony formation assay. Data were showed as mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001.
