Figure 1: Rectal temperatures in wild type (WT) and UCN1 KO mice kept for 2 hours at room temperature (RT, 22°C) or at 4°C. Rectal temperature was measured with an electronic probe every 10 min. The data are means ± SEM ( at 22°C and at 4°C) and are recorded from female WT (FWT, empty circles, solid lines), female UCN1 KO (FKO, filled circles, dotted lines), male WT (MWT, empty squares, solid lines), and male UCN1KO (MKO, filled squares, dotted lines).
