Abstract:
Circular RNA(circRNA)represents a unique class of closed-loop structured non-coding RNAs involved in various biological processes such as cell proliferation,differentiation,and apopto-sis.They play a significant role in the development of numerous diseases,and also serve as poten-tial biomarkers and therapeutic targets.To explore the impact of circRNA on viral replication,this study performed an omics measurement and analysis of circRNA differential expression in MC38 cells infected with HY12 enterovirus.It was found that,following HY12 virus infection,the ex-pressionlevels of 570 circRNAs were upregulated,while 381 circRNAs were downregulated.A-mong the upregulated circRNAs,the significantly upregulated circRNA mmu_circ_0001083 was selected for further investigation into its association with HY12 infection and its impact on viral replication.The results indicated that after HY12 virus infection,the expression of host circRNA mmu_circ_0001083 significantly increased,and its expression level was dependent on the virus dos-age and time.Compared to normal MC38 cells infected with the HY12 virus,cells with knocked down expression of circRNA mmu_circ_0001083 showed reduced expression of the 2C protein and significantly lower viral titers.Conversely,after HY12 virus infection in MC38 cells with overexpressed circRNA mmu_circ_0001083,there was an increase in the expression of the 2C pro-tein and a significant rise in viral titers.These results suggest that the upregulation of host cir-cRNA mmu_circ_0001083 is significantly positively correlated with the replication of HY12 virus,meaning mmu_circ_0001083 plays a positive regulatory role in the replication of HY12.This find-ing lays a foundation for future in-depth studies on the regulatory mechanisms of circRNA on viral replication.
