Resveratrol regulates arginine metabolism in mice colon. A–C qRT-PCR analysis of the mRNA expression level of the arginine metabolism-related molecules (iNOS, Arg1, Slc6a8) in mouse colon tissues. D–E Western blot analysis of the protein expression level of arginine metabolism-related molecules in mouse colon tissues and its grayscale scanning analysis. F IHC analysis of Slc6a8 expression in mouse colon tissues (200 ×). G Representative images of IF staining for iNOS and Arg1 on sections of mouse colon tissues (200 ×). * represents p < 0.05, ** represents p < 0.01 and *** represents p < 0.001
