For further validation of circNFATC3-IGF2BP3 interaction, we firstly designed two siRNAs targeting circNFATC3(si-circNFATC3-1 and si-circNFATC3-2) and evaluated the expression of circNFATC3 and linear NFATC3 after circNFATC3 knockdowns in GC cells. The gene discussed is NFATC3; the disease is gastric cancer.
