Resveratrol was suggested to inhibit Toll-like receptor (TLR)4-mediated activation of nuclear factor-κB (NF-κB) and Toll/interleukin-1 receptor domain-containing adaptor inducing interferon-β (TRIF)-(TANK)-binding kinase 1, but the myeloid differentiation primary response gene 88-tumor necrosis factor receptor-associated factor 6 (TRAF6) pathway is not involved in this effect. However, involvement of TRAF6 in this process is still elusive since cross talk between TRIF and TRAF6 has been reported in lipopolysaccharide (LPS)-induced signaling. Using RAW 264.7 macrophages, we determined the effect of resveratrol on LPS-induced TRAF6 expression, ubiquitination as well as activation of mitogen-activated protein (MAP) kinases and Akt in order to elucidate its involvement in TLR4 signaling. LPS-induced transient elevation in TRAF6 mRNA and protein expressions is suppressed by resveratrol. LPS induces the ubiquitination of TRAF6, which has been reported to be essential for Akt activation and for transforming growth factor-β activated kinase-1-NAP kinase kinase 6 (MKK6)-mediated p38 and c-Jun N-terminal kinase (JNK) activation. We found that resveratrol diminishes the effect of LPS on TRAF6 ubiquitination and activation of JNK and p38 MAP kinases, while it has no effect on the activation of extracellular-signal-regulated kinase (ERK)1/2. The effect of resveratrol on MAP kinase inhibition is significant since TRAF6 activation was reported to induce activation of JNK and p38 MAP kinase while not affecting ERK1/2. Moreover, Akt was identified previously as a direct target of TRAF6, and we found that, similarly to MAPKs, phosphorylation pattern of Akt followed the activation of TRAF6, and it was inhibited by resveratrol at all time points. Here, we provide the first evidence that resveratrol, by suppressing LPS-induced TRAF6 expression and ubiquitination, attenuates the LPS-induced TLR4-TRAF6, MAP kinase and Akt pathways that can be significant in its anti-inflammatory effects.
