Body weight before (a, d), during (b, e), and after (c, f) exposure to cafeteria diet in PENK (a–c) or BEND (d–f) KOs and their respective wild-type mice. (a, d) Weekly body weights for PENK KO (n=13), BEND KO (n=8), and wild-type mice (n=17 and n=8, respectively), during the 7 weeks of palatability testing preceding access to cafeteria diet. (b, e) Daily body weight during access to cafeteria diet, normalized to last standard chow access day (BL). (c, f) Body weights after access to cafeteria diet, normalized to last cafeteria diet access day (BL). Data are presented as mean±SEM. Horizontal and vertical bars with asterisks (*) indicate statistically significant (p<0.05) main effects of day and genotype, respectively. Pound sign (#) indicates significant (p<0.05) day x genotype interaction. Insets (b–f) show body weight in grams on baseline day—in these cases, horizontal bar with asterisks indicate statistically significant genotype effect.
