Circ_0109320 exerts oncogenic roles through the miR-595/E2F7 pathway in NSCLC. (A, B) RT-qPCR was used to determine the miR-595 expression after transfection. (C, D) Western blot was carried out to evaluate the E2F7 protein expression after transfection. (E, F) CCK-8 assays was used to detect the cell viability after transfection. (G, H) Apoptosis after transfection was evaluated using western blot. (I, J) Transwell assays were applied for exploring cell invasion after transfection. * P<0.05, ** P<0.01. NSCLC – non-small cell lung cancer; RT-qPCR – reverse transcription-quantitative polymerase chain reaction; CCK-8 – Cell Counting Kit-8.
