Fig 1. Baseline characteristics of 14 weeks old male BL6 mice treated with GlcNAc or kept on ad libitum standard chow.

A) and B) Baseline creatinine and urea values (control n = 5, GlcNAc i.p. n = 5, GlcNAc gavage n = 6) C) Plasma GlcNAc levels 2 hours after gavage of 250 μl of a 10% GlcNAc solution (n = 6) and in control animals with ad libitum access to water and standard chow (n = 5). D) Weight curves of control mice (n = 10) and mice kept on a 4 weeks ad libitum diet of chow enriched with 0.5% GlcNAc (n = 9).
