Figure 4.
Food intake and body weight loss in WT (n = 17) and Npas2 KO (n = 13) mice after 16 hr overnight food deprivation. A, feeding measured in a 4-hour test after the fast did not differ by genotype (P = 0.51). B, body weights before the fast did not differ between WT and KO mice (P = 0.1). C, body weight lost after a 16-hr overnight fast was expressed as percentage of the initial weight. KO mice lost significantly more weight than WT after the fast. * P < 0.05 KO vs. WT.
