Abstract:
Neuropathic pain (NP) results from a lesion or disease of the nervous system and accompanied by chronic pain, leading a serious public health issue and economic burden. In terms of the NP mechanisms remaining poorly understood, circular RNAs (circRNAs), owing to their high stability and evolutionary conservation, are expected to be used as potential therapeutic targets or diagnostic biomarkers. In this review, we concisely discuss the characteristics and biological functions of circRNAs. As emerging evidence we reviewed, deregulation of circRNAs (e.g., circ-Filip1l, circHIPK3, ciRS-7, circRNA.2837, circ-Ankib1 and circAnks1a) were involved in NP development. It suggested that specific circRNAs modulated through sponging their target miRNAs and thus regulated the homologous downstream mRNAs and proteins in neuropathic pain. These findings provide a theoretical basis for circRNAs use as biomarkers and therapeutic targets in neuropathic pain.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
