Mechanistically, RNA pull-down and RNA RIP assays demonstrated that hsa_circ_0074158 directly binds to the RNA-binding protein (RBP) EIF4A3, which decreases the stability of CTNNA1 (mRNA) and the production of α-catenin, subsequently impairing endothelial barrier function in sepsis. Here, EIF4A3 is linked to Sepsis.
