| Abstract: | Schwann cells proliferation is the main characterize of kinds PNS inflammation diseases. It has been well documented that cyclin D3 /CDK11p58 complex inhibits cell function through multiple mechanisms, but the mechanism of cyclin D3/CDK11p58 complex exerts its repressive role in the Schwann cells proliferation remains to be identified. In the present investigation, we demonstrated that the expression of CDK11p58 were upregulated in the inflammation caused by LPS, a main part of bactria. Cyclin D3 and the 58-kDa isoform of cyclin-dependent kinase 11 (CDK11p58) interacted with each other mainly in nuclear region, repressed Schwann cells proliferation and induced cell apoptosis. Overexpression of CDK11p58 expression might enhance this process, while silence of cyclin D3 reverting it. This work demonstrates for the first time the role of cyclin D3/CDK11p58 complex in repressing the Schwann cells proliferation and inducing its apoptosis. |
