Table 1

(a) EET-agonist treatment (4 weeks) WT and Ln PGC-1α(sh) mice. Body weights, fasting blood glucose, blood pressure, oxygen consumption, and respiratory quotient of mice fed regular chow or HF diet for 8 weeks. EET-A administered for the last 4 weeks. (b) EET-agonist treatment (8 weeks) WT mice. Body weights, blood glucose, oxygen consumption, and respiratory quotient of mice fed regular chow or HF diet for 24 weeks. EET-A administered for the last 8 weeks.
