Because pregnancy causes reduced sensitivity to hormones regulating food intake, including leptin and cholecystokinin (Ladyman and Grattan, 2004; Ladyman et al., 2011), we assessed if the action of the satiating hormone amylin is preserved in pregnant rat dams maintained on either chow or HE diet (Figures 3C–F). The gene discussed is CCK; the disease is hereditary elliptocytosis.
