ABSTRACT
With the in-depth study of circRNA, more and more biological studies have shown that circRNAs play an important role in mammals, such as cell proliferation, apoptosis, invasion, development and disease state. However, the regulatory mechanism of circRNA in lower vertebrates remains unclear. Here, we found a new circular RNA and named it circRara. We carried out the experimental study on its antiviral and antibacterial response, cell proliferation and activity. The results showed that circRara had a positive regulatory effect on the antiviral and antibacterial response, cell proliferation and activity in miiuy croaker. First, we found that the expression of circRara could be up-regulated under the stimulation of LPS and poly (I C), but not the expression of linear Rara. In addition, the increase of circRara can increase the production of inflammatory factors and antiviral genes, which was confirmed by double luciferase reporter gene experiment and qPCR. These results will help to further understand the immunomodulatory mechanism of circRNA in teleost fish.
