Impact of Grx2−/− on whole body energetics and mouse physiology.
a, mouse weight. Student's t test, n = 4, mean ± S.E. b, effect of Grx2−/− on tissue and organ weights. Student's t test, n = 4, mean ± S.E. BAT, interscapular brown adipose tissue; GWAT, gonadal white adipose tissue. c, hematoxylin and eosin staining of gastrocnemius (×40 objective) and liver (×20 objective) cross-sections. d, measurement of whole body energetics by indirect calorimetry. n = 6. e, impact of Grx2−/− on respiratory exchange ratio (RER) and mouse activity in WT and Grx2−/− mice during light and dark phases. Student's t test, n = 6, mean ± S.E. f, daily food intake. Measurements were taken every 3–4 days and corrected for spillage. n = 5, mean ± S.E.
