The expression level of circ_0020850 in lung adenocarcinoma tissues and cells. A, B The differentially expressed circRNAs were presented based on GSE101684 data. C GSE101684 data showed circ_0020850 level in lung adenocarcinoma tissues and normal tissues. D, E RT-qPCR was used to detect circ_0020850 level in lung adenocarcinoma tissues and cells, as well as in matched control groups. F, G The relative expression level of circ_0020850 and linear-NUP98 were assessed by RT-qPCR after treating with RNase R. *P < 0.05
