Delta-aminolevulinate dehydratase activity in mice with hereditary anemia

Science

Abstract

Homozygous (f/f) but not heterozygous (f/+) mice of the highly congenic strain, FL/ Re, manifest a severe transitory siderocytic fetal anemia. Adults of both f/f and f/+ genotype manifest decreased hepatic, splenic, and renal levels of triangle up-amino-levulinate dehydratase (ALD) activity compared to homozygous (+/+) mice of the same strain. The degree of augmentation in splenic ALD activity following phenylhydrazine administration is high in +/+, intermediate in f/+, and low in f/f mice. These findings suggest that perhaps a deficiency in the fetal level of ALD may be responsible for the transitory fetal anemia.

Adrenoleukodystrophy

Adrenoleukodystrophy (ALD), the most frequent peroxisomal disorder, is an X-linked disorder caused by a defect in the metabolism of long chain fatty acids leading to demyelination, neurodegeneration, and death. Here is the latest research.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
