Circular RNAs (circRNAs) are critical regulators in the occurrence and development of numerous cancers, in which abnormal autophagy plays a key role. However, the potential involvement of circRNAs in autophagy is largely unknown. Here, we identified the overexpression of circTICRR, a circular RNA, in cervical cancer. In vitro experiments showed that knockdown of circTICRR activated autophagy, and consequently promoted apoptosis and inhibited proliferation in cervical cancer cells, and vice versa. CircTICRR interacted with HuR protein via binding to F287/F289 in the RRM3 domain of HuR, stabilizing GLUD1 mRNA and elevating the level of GLUD1 protein. In vivo experiments revealed that knockdown of circTICRR suppressed the growth of transplanted tumors. An inhibitory peptide specific to the binding site between circTICRR and HuR protein promoted autophagy, induced apoptosis, suppressed proliferation in cervical cancer cells, and inhibited the growth of xenografts. Our findings suggest that circTICRR acts as an oncogene in cervical cancer and the interaction between circTICRR and HuR protein may be a potential target in cervical cancer therapeutics.
