Other murine models target genes relevant to AMD, including inflammatory genes such as Cfh(-/-), Ccl2(-/-), Ccr2(-/-), Cx3cr1(-/-), and Ccl2(-/-)/cx3cr1(-/-), oxidative stress associated genes such as Sod1(-/-) and Sod2 knockdown, metabolic pathway genes such as neprilysin(-/-) (amyloid beta), transgenic mcd/mcd (cathepsin D), Cp(-/-)/Heph(-/Y) (ferroxidase ceruloplasmin/hepaestin, iron metabolism), and transgenic ApoE4 on high fat and high cholesterol diet (lipid metabolism).
Accordingly, SOD1 could be used as a potential agent in the treatment of hypercholesterolemia, even in subjects lacking a functional LDL receptor pathway.
Moreover, the hypercholesterolaemia characterised by elevated lipid peroxidation (MDA) and reduced antioxidant enzyme defences (SOD, CAT and GPx) was restored by POS treatment.
