Gene Affected Lipa: lipase A, lysosomal acid, cholesterol esterase
Origin In a colony of Donryu rats, Yoshida found a male rat showing hepatomegaly and splenomegaly in 1981 (Yoshida, 1990). These mutant rats were transferred to Kagoshima University and maintained in heterozygous condition so far. ALD (acid lipase deficiency). (Mar 15, 2010)
Strain characteristics ALD rats have congenital deficiency of lysosomal acid lipase. Affected rats markedly accumulate cholesteryl ester, free cholesterol and triglyceride in the liver, and cholesteryl esters and free cholesterol in the spleen (Kuriyama, 1990; Kuriwaki, 1999). ALD is a disease model for Wolman’s disease.
ALD rat has a large deletion at the 3’-end of the Lipa gene (Nakagawa, 1995). (Mar 15, 2010)
Breeding Conditions Homozygous animals die until 120 days of age from liver failures. Homozygous ALD rats are infertile. Maintained in heterozygous condition. (Mar 15, 2010)
Genotyping Please refer to reference 3 (Nakagawa, 1995). Genotyping protocol for Lich
