Deficiency of Galactosidase Activity in Multiple Organs in GM2-Deficient Mice
WHT/Ht mice are known to have GM2 deficiency especially in the liver. In order to know the relationship of this abnormality to the general metabolism in organs or cells, we compared 17 hydrolytic enzyme activities in the liver, brain, spleen, and kidney between the WHT/Ht mice and control BALB/c mic...

Summary: | WHT/Ht mice are known to have GM2 deficiency especially in the liver. In order to know the relationship of this abnormality to the general metabolism in organs or cells, we compared 17 hydrolytic enzyme activities in the liver, brain, spleen, and kidney between the WHT/Ht mice and control BALB/c mice or without administration of GM2 and GM3. Regardless of the GM2 or GM3 treatment, the galactosidase activity was markedly low in all of the tested organs in the WHT/Ht mice when compared with that in the control animals. This consistency stands in contrast with the known organ-dependent heterogeneity of ganglioside expression and thus indicates independency of the GM2 deficiency from the galactosidase deficiency in this model animal. |
