Among others, gene therapy substituting the loss of essential enzymes is already used for Lipoprotein Lipase (LPL) deficiency in autosomal chylomicronaemia and is expected to eliminate the lack of Low- Density Lipoprotein (LDL) receptors in patients with homozygous familial hypercholesterolaemia.
To test the hypothesis that stimulation of LPL expression may be used as an adjunctive therapy for treatment of homozygous familial hypercholesterolemia, we have generated transgenic (Tg) Watanabe heritable hyperlipidemic (WHHL) rabbits that overexpress the human LPL transgene and compared their plasma lipid levels, glucose metabolism, and body fat accumulation with those of non-Tg WHHL rabbits.
