摘要
Objective: To study the effect of decoy-oligodeoxynucleotides (decoy-ODNs) in dumbbell shape with the oligodeoxynucleotide sequence similar to nuclear factor kappa B (NF-κB) cis-elements on expression of inflammation mediators in pMΦ cells from rats. Methods: With carriers of cationic liposomes, decoy-ODNs were transfected into pMΦ cells of rats. Then the inhibiting effects of the decoy-ODNs on tumor necrosis factor α (TNFα), interleukin-6 (IL-6) and IL-10 were analyzed. Results: Decoy-ODNs could decrease the expression of TNFα and IL-6 in dose-dependent fashion but had weaker inhibiting effect on IL-10. Conclusions: Decoy-ODNs targeting NF-κB can decrease the expression of inflammatory mediators in pMΦ cells from rats.
