Aim: To study the expression pattern of circular RNAs in diabetic peripheral neuropathy. Materials & methods: Transmission electron microscopy was used to observe the ultrastructure of sciatic nerves and dorsal root ganglion (DRGs). circRNAs in DRGs were identified with high-throughput RNA sequencing. Whole-genome mRNAs were detected by a chip scan. Results: The ultrastructure of sciatic nerves and DRGs in diabetes mellitus mice changed significantly. A total of 11,004 circRNAs and 15 differentially expressed circRNAs, as well as 35,368 mRNAs and 133 differentially expressed mRNAs were identified in DRGs between wild-type and diabetes mellitus mice. 11 circRNAs and 14 mRNAs have a significant correlation using strict coexpression analysis. The expression of circRNA.4614 was validated to be upregulated significantly. Conclusion: Our study suggested that circRNAs might be involved in the regulation of mRNA expressions in diabetic peripheral neuropathy.
