PF could suppress iNOS and inflammatory factor levels in HG-induced macrophages. (A–D) Effects of PF treatment and TLR4 deficiency on HG-stimulated iNOS and inflammatory cytokine expression. BMDMs were treated with HG stimulation for 24 h, and mRNA levels were detected by qRT-PCR. (E–G) Detection of the levels of TNF-α, IL-1β, and MCP-1 secreted by HG-stimulated BMDMs. Conditioned medium was removed, and ELISAs were used to detect soluble TNF-α, IL-1β and MCP-1 peptides. P < 0.05 and ∗∗P < 0.01 vs. the LG group; ##P < 0.01 vs. the HG group; ▲▲P < 0.01 vs. the TLR4-/-+HG group; NS: not significant.
