Adipose Tissue-specific PTEN Knockout Mice
- 详细技术说明
- UCLA researchers have developed a mouse model to explore the mechanisms by which insulin signaling in adipose tissue regulates systemic insulin sensitivity. A targeted deletion of PTEN in adipose tissue was accomplished by utilizing the Cre-lox system under control of the aP2 adipose specific promoter. Loss of PTEN results in improved systemic glucose tolerance and insulin sensitivity. In addition, mutant animals exhibit increased insulin signaling and AMP kinase activity in the liver.

Background
Aberrant glucose uptake due to insulin resistance is a key pathogenic feature of type 2 diabetes. Insulin signals through its cell surface receptor (IR). The binding of insulin to IR leads to the activation of the PI3-kinase pathway. A phosphatase and tensin homolog deleted from chromosome 10 (PTEN) is a negative regulator of the PI3-kinase/AKT pathway and is hypothesized to inhibit the metabolic effects of insulin. Understanding insulin signaling will lead to new targets for interventions aimed at reversing insulin resistance.
