While IsoPs and NeuroPs have been established as a reliable measurement of lipid peroxidation and oxidative stress in vivo , we show that in this genetic SLOS mouse model , 7 - DHC - derived oxysterols are present at much higher levels than IsoPs and NeuroPs and thus are better markers of lipid oxidation and related oxidative stress .
