PER2 and ischemia: In line with studies on a Per2 dependent inhibition of fatty acid beta-oxidation [24], total lipid and MUFA levels significantly decreased during ischemia in Per2−/− (Total lipids/MUFA Baseline (B) Per2−/−: 54.2 μmol/g (SD5.0) /15.0 μmol/g (SD2.4) vs. Ischemia (I) Per2−/−: 40.0 μmol/g (SD4.2)/ 11.0 μmol/g (SD1.0), P = 0.02/P<0.0001, n = 3).
