circ_0007766对肺腺癌细胞增殖能力的影响。CCK8实验检测细胞转染后0 h、24 h、48 h、72 h及96 h时的细胞活力。每组设置5个复孔，用酶标仪测定在450 nm处的吸光度，并测定各孔的OD值。

Effect of circ_0007766 on cell proliferation of lung adenocarcinoma cell lines. CCK8 assay was carried out to detect the cell viability of cells transfected by siRNA for 0 h, 24 h, 48 h, 72 h and 96 h. Five compound pores were set in each group. The absorbance at 450 nm was measured by enzyme labeling instrument, and the OD value of each pore was determined.
