Glutathione & oxidative stress

It is known that there is an increase of oxidative stress in Down syndrome due to over expressions of certain genes. There is also a decrease of glutathione due to over expressed genes. I happened to come across a study today while I was searching PubMed that was done in April 2008. It is called, A mathematical model of glutathione metabolism. This study was done at Duke University.

In the conclusion in the abstract it states,

"The model shows that overexpression of genes on chromosome 21 and an increase in oxidative stress can explain the metabolic profile of Down syndrome."

I thought this was interesting. It shows one of the mechanisms and reasons why glutathione is low in DS. The full text of the study can be seen here.
