Article Title: CircFRRS1 drives neuroinflammation through the miR-27a-3p/TLR4 pathway after deep hypothermic circulatory arrest
doi: 10.3389/fncel.2026.1750887
Figure Lengend Snippet: Dual luciferase reporter experiment confirmed the regulatory relationships of circFRRS1/rno-miR-27a-3p and rno-miR-27a-3p/TLR4 pairs. (A) The predicting binding site between circFRRS1 and miR-27a-3p. (B) Dual luciferase reporter assay revealed that miR-27a-3p attenuated the luciferase activity of circFRRS1-WT, but not of circFRRS1-MUT. (C) The predicting binding site between TLR4 and miR-27a-3p. (D) Dual luciferase reporter assay revealed that miR-27a-3p attenuated the luciferase activity of TLR4 3’-WT, but not of TLR4 3’-MUT. ** p < 0.01, *** p < 0.001, vs. control group; # p < 0.05, ### p < 0.001, vs. WT group.
Article Snippet: The shRNA lentiviral vectors targeting circFRRS1 (sh-circFRRS1) and the negative control (sh-NC) were obtained from Genechem (Shanghai, China).
