Fig. 2. Mating induces gut NPF that suppresses sugar appetite and promotes intake of protein-rich yeast food in females.

a, Time spent feeding on 1 or 10% sucrose using FLIC; all n = 12 animals. b,c, Preference between 1 versus 10% sugar measured over 6 or 24 hours by CAFÉ assay. b, 6-hour preference: n = 10 EEC>, n = 9 EEC>NPFiKK. 24-hour preference: n = 10 each. c, n = 14 NPFgut>, n = 15 NPFgut>NPFiTRiP. d, Midgut NPF staining intensity in fed females on a per-cell basis and on a per-gut basis; n = 703 cells from seven guts for virgins, n = 883 cells from seven guts from mated females. e, NPF-cell activity measured in dissected midguts (two midguts per replicate) using a luciferase-based CaLexA calcium-reporter system (NPF>LexA::NFAT::VP16; LexAop-luciferase); n = 4 from fed virgins, n = 4 from fed females mated to SP-deficient males (SP0/Df(3L)delta130), n = 6 from fed females mated to SP+ males. f, Consumption preference for 10% sucrose versus 10% yeast after 3 days of yeast deprivation (3 days on sucrose-only medium) using two-choice dye assay; n = 25 NPFgut> virgins, n = 23 NPFgut>NPFiTRiP virgins, n = 24 NPFgut> mated females, n = 22 NPFgut>NPFiTRiP mated females, n = 17 EEC> virgins, n = 18 EEC>NPFish virgins, n = 18 EEC> mated females, n = 18 EEC>NPFish mated females. g, Yeast consumption determined by dye assay; virgins n = 10 NPFgut> virgins, n = 6 NPFgut>NPFiTRiP virgins, n = 9 NPFgut> mated females, n = 8 NPFgut>NPFiTRiP mated females. h, Yeast intake determined by CAFÉ; n = 32 NPFgut>, n = 26 NPFgut>NPFiTRiP. i, Cumulative behavioural preference of females for sucrose versus yeast monitored using flyPAD. Lines represent means, and shading indicates s.e.m.; n = 24 NPFgut> virgins, n = 23 NPFgut>NPFiTRiP virgins, n = 24 NPFgut> mated females, n = 24 NPFgut>NPFiTRiP mated females. Bars represent mean ± s.e.m. Box plots indicate minimum, 25th percentile, median, 75th percentile and maximum values. NS, not significant. a,c,d (left), Two-tailed unpaired Mann–Whitney U-test. b,d (right), h, Two-tailed unpaired Student’s t-test. e,f (right), g, One-way ANOVA with Tukey’s post hoc test. f (left), i, Kruskal–Wallis nonparametric ANOVA with Dunn’s multiple-comparisons test.
