Improved methods for detection of β-galactosidase (lacZ) activity in hard tissue [PDF]

, 2012
The ß-galactosidase gene (lacZ) of Escherichia coli is widely used as a reporter gene. The expression of lacZ can be detected by enzyme-based histochemical staining using chromogenic substrates such as 5-bromo-4-chloro-3-indolyl-ß-D: -galactoside (X-gal).

Significance of bound glutarate in the diagnosis of glutaric aciduria type I

Journal of Inherited Metabolic Disease, 1992
Glutaric aciduria type I (GA-I) (McKusick 231670) is an autosomal recessive disorder caused by glutaryl-CoA dehydro genase (GD) deficiency. The diagnosis of GA-I is determined by organic acid analysis of urine and is confirmed by measuring the enzyme activity in cultured skin fibroblasts or leukocytes.

Effects of Imipramine and Lithium on the Suppression of Cell Proliferation in the Dentate Gyrus of the Hippocampus in Adrenocorticotropic Hormone-treated Rats [PDF]

, 2010
We examined the influence of chronic adrenocorticotropic hormone (ACTH) treatment on the number of Ki-67-positive cells in the dentate gyrus of the hippocampus in rats. ACTH treatment for 14 days decreased the number of such cells.

Mammalian Metabolism of Glutaric Acid

Journal of Biological Chemistry, 1969
Abstract Rat liver mitochondria metabolize glutarate at a very slow rate as compared with glutaryl coenzyme A. The stimulatory effect of citric acid cycle intermediates, NAD, and coenzyme A on glutarate metabolism was interpreted as a manifestation of their involvement in the activation of glutarate by a thiol transferase with succinyl-CoA as the ...
