Effect of a low-protein diet supplemented with rumen-protected methionine and lysine on the expression of genes related to m6A RNA methylation in liver (A, B, C) and muscle (D, E, F). Data are expressed as means ± SEM indicated by vertical bars. Different letters indicate a significant difference among the three dietary treatments (P < 0.05). NP: adequate protein diet (n = 7), LP: low-protein diet (n = 6), LP + RML: low-protein diet supplemented with rumen-protected methionine and lysine (n = 7)
