circAHNAK1 acts as a ceRNA to regulate RASA1. (A)Predicting the binding site of miR-421 in the RASA1-3′UTR region by TargetScan;(B) Luciferase assay after transfection with miR-421 mimics or inhibitor (C) Detection of RASA1 expression after miR-421 transfection by qRT-PCR; (D) Detection of RASA1 expression after transfection by immunofluorescence; (E)Detection of RASA1 expression after transfection by western blots. (F)Ago2-RIP assay showed enrichment of circAHNAK1, RASA1 and miR-421 on Ago2; (G) Ago2-RIP assay showed the effect of circAHNAK1 overexpression on RASA1 enrichment; (H) qRT-PCR detected RASA1 expression after transfection of circAHNAK1 and/or miR-421; (I)Western blots detected RASA1 expression after transfection of circAHNAK1 and/or miR-421;
