Fig. 4. The RNA-binding protein EIF4A3 regulates hsa_circ_101555 expression.

A Binding sites for EIF4A3 on the CSNK1G1 mRNA transcript, upstream or downstream of hsa_circ_101555, obtained from Circular RNA Interactome. B Pull-down assay confirms the enrichment of EIF4A3 protein in CSNK1G1 mRNA pull-down. C Quantitative real-time PCR following EIF4A3-RIP assay confirms the binding of EIF4A3 on the predicted binding region (a, b, c, and d) of CSNK1G1 mRNA. H19, a known interacting long noncoding RNA (lncRNA) with EIF4A3, served as the positive control. The intron 10 of CSNK1G1 mRNA was used as a negative control. D HCCLM3 and HepG2 cells transfected with control or siRNA targeted eIF4A3; hsa_circ_101555 expression detected by qRT-PCR. E HCCLM3 and HepG2 cells transfected with control or eIF4A3 overexpression plasmids; hsa_circ_101555 expression measured by qRT-PCR. F HCCLM3 and HepG2 cells transfected with control or siRNA targeted hsa_circ_101555; eIF4A3 expression detected by qRT-PCR.
