4-MU and 4-MUG concentrations in serum and organs from 4-MU and 4-MUG treated mice. A, C, E, G, and I, 4-MU and 4-MUG concentrations were analyzed in the serum (A), pancreas (C), fat (E), liver (G), and muscle (I) from untreated control mice and 4-MU– and 4-MUG–treated mice using LC-MS/MS. n = 3–5 mice per group. B, D, F, H, and J, calculated molar ratio of 4-MU and 4-MUG from serum (B), pancreas (D), fat (F), liver (H), and muscle (J) in the different treatment groups. Data represent mean ± S.E.
