What this study shows

mTORC1 inhibition reverses neurological abnormalities in neural Pten-knockout mice.

Abstract

ShowHide

PTEN (phosphatase and tensin homolog deleted on chromosome ten) is a lipid phosphatase that counteracts the function of phosphatidylinositol-3 kinase (PI3K). Loss of function of PTEN results in constitutive activation of AKT and downstream effectors and correlates with many human cancers, as well as various brain disorders, including macrocephaly, seizures, Lhermitte-Duclos disease, and autism. We previously generated a conditional Pten knock-out mouse line with Pten loss in limited postmitotic neurons in the cortex and hippocampus.
