Effect of decoy-oligodeoxynucleotides on expression of inflammation mediators in pMPhi cells from rats

Chin J Traumatol. 2003 Dec;6(6):363-9.

Abstract

Objective: To study the effect of decoy-oligodeoxynucleotides (decoy-ODNs) in dumbbell shape with the oligodeoxynucleotide sequence similar to nuclear factor kappa B (NF-kappaB) cis-elements on expression of inflammation mediators in pMPhi cells from rats.

Methods: With carriers of cationic liposomes, decoy-ODNs were transfected into pMPhi cells of rats. Then the inhibiting effects of the decoy-ODNs on tumor necrosis factor alpha (TNFalpha), interleukin-6 (IL-6) and IL-10 were analyzed.

Results: Decoy-ODNs could decrease the expression of TNFalpha and IL-6 in dose-dependent fashion but had weaker inhibiting effect on IL-10.

Conclusions: Decoy-ODNs targeting NF-kappaB can decrease the expression of inflammatory mediators in pMPhi cells from rats.
