Table 2. Serum lipid levels of mice under different dietary and locomotor activity conditions.

Animal and treatment	n	TG (mmol/L)	TC (mmol/L)
C57BL/6J, regular chow, WR (−)	6	1.73 ± 0.18	3.98 ± 0.47
ApoE−/−, regular chow, WR (+)	6	0.91 ± 0.11**	6.48 ± 0.63**
ApoE−/−, fat chow, WR (+)	6	1.89 ± 0.16ΔΔ	6.94 ± 0.67
ApoE−/−, fat chow, WR (−)	6	2.27 ± 0.24#	12.63 ± 1.65##

TG, total triglyceride; TC, total cholesterol; WR (+), with wheel running; WR (−), without wheel running. **P < 0.01 vs. the respective TG or TC level of C57BL/6J mice with regular chow but without wheel running. ^ΔΔP < 0.01 vs. the TG level of ApoE^−/− mice with 1%-fat chow and wheel running. ^#P < 0.05 vs. the TG level of ApoE^−/− mice with 1%-fat chow and wheel running. ^##P < 0.01 vs. the TC level of ApoE^−/− mice with 1%-fat chow and wheel running. Mean and SD were shown for each group (n = 6).
