Considering that the expression levels of WNK2, CYP1A1, PAX5, XRCC1, and TGM3 have been reported to be closely related to the development of cancer [16–19], we then detected the expression levels of these genes in SK-MES-1 and A549 cells after transfection of circFLNA and miR-486-3p mimic. Here, XRCC1 is linked to cancer.
