Resveratrol regulates arginine metabolism in macrophages in vitro. A–D qRT-PCR detection of cytokines expression in RAW264.7 cells. E–G qRT-PCR analysis of the mRNA expression level of the mRNA level of arginine metabolism-related molecules (iNOS, Arg1, Slc6a8) in RAW264.7 cells. H, I Western blot analysis of the protein expression level of arginine metabolism-related molecules in RAW264.7 cells and its grayscale scanning analysis. * represents p < 0.05, ** represents p < 0.01 and *** represents p < 0.001
