BMMs from WT mice were pretreated with PI3K inhibitor LY294002 or DMSO, followed by LPS +/− CoPP. (A) Western-assisted expression of Nrf2, p-Akt, Foxo1, TLR4 and NF-κB. β-actin served as an internal control. Representative of three experiments. (B–E) Quantitative RT-PCR-assisted detection of TNF-α, IL-1β, MCP-1 and CXCL-10. Mean�SD; n=3–4/group; *p<0.05, **p<0.005.
