Background: Hepatic carcinoma (HC) is one of the leading causes of cancer-related death, and the incidence keeps high in the world. The vital role of circular RNAs (circRNAs) in HC development has been revealed to some extent. Circ_0000775, a novel circRNA, has never been thoroughly studied regarding HC., Methods: Online datasets were utilized to obtain expression pattern of genes in tumor tissues. RT-qPCR and western blot examined the RNA and protein levels of indicated genes. ChIP, DNA pull down, RNA pull down, RIP and luciferase reporter assays were carried out to verify correlation between different factors. Supported by RT-qPCR and western blot analyses, transwell and wound healing assay were implemented for detecting cell migration and invasion and EMT. Additionally, cell EMT was also evaluated via cell morphology observation for calculation of spindle cell number., Results: High expression of circ_0000775 in HC cells was induced by transcriptionally stimulation by TCF7L2. Circ_0000775 in cytoplasm recruited IGF2BP2 to enhance the mRNA stability of CDC27, thus positively modulating CDC27 expression. Circ_0000775 exacerbated HC cell migration, invasion and EMT through CDC27., Conclusion: TCF7L2 promoted the transcription of circ_0000775, and circ_0000775 recruited IGF2BP2 to maintain CDC27 mRNA stability, thereby facilitating HC cell migration, invasion and EMT., (Copyright © 2022 Elsevier GmbH.
