Article Title: Long-lived weight-reduced αMUPA mice show higher and longer maternal-dependent postnatal leptin surge

doi: 10.1371/journal.pone.0188658

Figure Lengend Snippet: Each time point represents the mean ± s.e.m. of 5 to 17 mice (see for details). Pups were sampled every four days, following four hours of chow deprivation (first experiment), and were weaned at day 24 (P24). (A) Postnatal circulating leptin level measured using ELISA kit (R&D Systems Inc.). Insert of A. Mean P4-P24 leptin level. Bars with different letters are significantly different ( P <0.05, based on two-ways ANOVA followed by a post-hoc test). (B) Leptin:FM ratio. *, P <0.05 by post hoc comparison following one-way ANOVA of all four mice groups.

doi: 10.1371/journal.pone.0188658

Figure Lengend Snippet: Each time point represents the mean ± s.e.m. of 6 to 22 mice, females only. Pups were sampled every four days, following four hours of chow deprivation (first and second experiments) and dam deprivation (second experiment only). Leptin and corticosterone levels were measured using ELISA kits (R&D Systems Inc.). (A and B) Postnatal circulating leptin level of dam-deprived and non-deprived female WT (left) and αMUPA (right) mice. (C) Postnatal circulating leptin levels of dam-deprived female αMUPA and WT mice. (D) Postnatal body weight growth curves of dam-deprived and non-deprived female WT mice. (E) Postnatal body weight growth curves of dam-deprived and non-deprived female αMUPA mice. (F) Postnatal body weight growth curves of dam-deprived female αMUPA and WT mice. (G) Mean P4-P24 leptin level of dam-deprived and non-deprived female αMUPA and WT mice. (H) Corticosterone P12 level of dam-deprived and non-deprived female αMUPA and WT mice. Bars with different letters are significantly different ( P <0.05, based on two-ways ANOVA followed by a post-hoc test). *, P <0.05 by post hoc comparison following one-way ANOVA of all four mice groups.

Article Title: Long-lived weight-reduced αMUPA mice show higher and longer maternal-dependent postnatal leptin surge

doi: 10.1371/journal.pone.0188658

Figure Lengend Snippet: Bars represent the mean ± s.e.m. of 6 dams per strain (A) and their female pups (B), one female pup per dam, all sampled at P12. Dams' serum and milk samples (A) were obtained 4 hours after their separation from their pups. Milk secretion was encouraged by subcutaneous oxytocin injection (2 IU/kg) administered 15 min before sampling. Pups' serum and stomach content (B) were sampled 30 min after they were reunited with their dams. Leptin level was measured using ELISA kit (R&D Systems Inc.). *, P<0.05 between strains, by Mann-Whitney non-parametric test. #, P<0.05 within strains, by Wilcoxon non-parametric Test.
