Values represent percentage of body weight. D: Flow cytometry analysis of rdu-positive adipocytes in and epididymal adipose tissue. Values in bold represent percentage of rdu-positive adipocytes. and mice were injected intraperitoneally with 5 μg/g body weight of rdu for 3 consecutive days. dipocytes from epididymal adipose tissue were isolated, stained using rdu Flow kit and analyzed by flow cytometry as recommended by manufacturer (ecton Dickinson, Franklin Lakes, NJ). E: Representative hematoxylin-eosin stained paraffinembedded section of the and liver. Scale bars, 1 μm. F: Mean plasma cholesterol in and mice. Values represent mean ± SEM, n= 8/group.

F: The mean O 2 consumption (), CO 2 emission (), heat production (C), fuel consumption (D), and horizontal (E) and rearing (F) movements monitored over a 24-h light-dark cycle period. Horizontal movements (X amb ) and rearing movements (Z tot ) were measured by counting the number of horizontal and vertical infrared beam breaks. Respiratory exchange ratio (RER) was calculated by VO 2 /VCO 2.

Four experimental groups with a cohort of ten 8-week-old male mice each were assigned to either or (TestDiet, Richmond, IN) for 18 weeks. Group 1 and 3: and mice fed on (1% energy from fat, Yellow, 58Y2), respectively; Group 2 and 4: and mice fed on (45% energy from fat, Red, 58V8), respectively. C and D: Representative histological section (oil red O and methylene blue staining) of the skeletal muscle (C) and pancreas (D). Scale bars, 1 μm.
