摘要
ClC-5 is one of the voltage-dependent chloride channel (ClC) family members. Mutations involving CLCN5 cause an X-linked nephropathy associated with Dent's disease. Some Clcn5 gene knockout (ClC-5 KO) mice have abnormal growth of the teeth; however, the expression and function of ClC-5 during tooth development is still unknown. Herein we report abnormal dentin structure, decreased DSPP and increased TGF-beta 1 protein level in ClC-5 KO teeth. In odontoblast-like MDPC-23 cells, the mRNA levels of Tgfb1, Dspp and Dmp-1 were upregulated with Clcn5 RNAi after 48 h treatment; whilst there was no change in those of TGF-beta receptor Tgfbr1 and Tgfbr2. We suggest that the dentin changes in ClC-5 KO mice might be a result of increasing TGF-beta 1, and the interplay between ClC-5 and TGF-beta 1 needs further identified. (C) 2009 Elsevier Ltd.
