Abstract:
Objective To explore the role pathway and pattern of the sex determining region box transcription factor 2 (SOX2) and its mRNA interaction with microRNA(miRNAs, miR) and circular RNA(circRNA) at 0 hour and 2 hours in the rat liver regeneration. Methods The rat 2/3 hepatectomy (partial hepatectomy, PH) model was prepared as described by Higgins, the hepatocytes were isolated according to the method of Smedsrod et al, the expression changes of mRNA, miRNA and circRNA [together named as competing endogenous RNAs(ceRNA)] were detected by the large-scale quantitative detection technology, the interaction network of ceRNA was constructed by Cytoscape 3.2 software, and their correlation in expression and role were analyzed by ceRNA comprehensive analysis. Results It was found that at the 0 hour and 2 hours after PH, the ratio value of SOX2 mRNA shows 1.00±0.09 and 2.15±0.48, miR-3558-3p displays 4.53± 0.10 and 0.81±0.16, circRNA_18404 shows 1.24±0.04 and 11.10±0.57, circRNA_18045 displays 1.97±0.47 and 4.44± 0.23. At the same time, the eight kinds of cell dedifferentiation-related genes AT-rich interaction domain 5A (ARID5A), activating transcription factor 3 (ATF3), BTG anti-proliferation factor 2 (BTG2), etc, which are prometed in expression by SOX2, were down-regulated at 0 h after PH, but the cell differentiation-related genes interferon regulatory factor 6 (IRF6) and somatostatin (SST), which are inhibited in expression by SOX2, were up-regulated at 0 hour after PH. On the other hand, the eight kinds of cell dedifferentiation-related genes ARID5A, ATF3, BTG2, etc, which are promoted in expression by SOX2, were up-regulated at 2 hours after PH, but the cell differentiation-related gene SST, which is inhibited in expression by SOX2, was down-regulated, and IRF6 had no meaningful changes in expression at 2 hours after PH. Conclusion The correlation in expression and role of the miRNA, which are inhibited by circRNA, SOX2, its mRNA is inhibited by miRNA, and the cell stem-related genes, which are regulated by SOX2, are helpful for the hepatocyte to be in differentiation state at 0 hour after PH and to be in stem state at 2 hours after PH.
