| abstractText | The R553H mutation has been found in the FOXP2 gene of patients with speech-language disorder. Foxp2(R552H) knock-in (KI) mice exhibit poor dendritic development of Purkinje cells in the cerebellum and impaired ultrasonic vocalization (USV), which is related to human speech and language; compared with wild-type mice, heterozygous Foxp2(R552H)-KI pups exhibit the reduced number of whistle-type USVs and the increased short-type ones, while homozygous pups exhibit only click-type USVs but no whistle-type or short-type ones. To make clear the relationship between the role of Foxp2 in the cerebellum and whistle-type USVs activity, we prepared transgenic (Tg) mice specifically expressing human FOXP2-myc in cerebellum (Pcp2-FOXP2-myc-Tg mice) by using purkinje cell protein-2 (Pcp2) promoter. FOXP2-myc expression in the cerebellum increased the relative numbers of whistle-type USVs in the heterozygous Foxp2(R552H)-KI pups and recovered their USVs but did not in the homozygous ones. Foxp2 in the cerebellum may pertain to the brain network engaged in whistle-type USVs activities including modification, but not their production. There may be common molecular contribution of Purkinje cells to human FOXP2-mediated speech-language and mouse Foxp2-mediated USVs. |
