CETP and hyperlipidemia: Along with the switch from NO-dependent to H2O2-dependent vasodilation in the aorta in young female E3L.CETP mice, we identified a number of sex-specific hyperlipidaemia-dependent DEPs in 8-week-old E3L.CETP mice, while in older mice (28-week-old), the number of hyperlipidaemia-dependent DEPs was comparable between sexes.
