Methodolology: We will perform studies on hepatic cell systems where ATM protein production has been enhanced or removed through genetic manipulation. This will include the study of gluconeogenesis, insulin uptake, insulin sensitivity, and hepatic glucose output. This model will also be used to comapre the effect of different ATM mutations found in human patients with A-T. In addition we will utilise the ATM null mouse and the heterozygotic mouse to study the endocrine response to oral and i.v. glucose, as well as the response to the diabetes drugs metformin and pioglitazone, in order to dissect which tissues contribute to the defects seen in the A-T patients. Finally we will investigate whether ATM inhibitors (available from Astra Zeneca) can mimic the defects seen in the genetic ATM models.
