| Outline of Final Research Achievements |
Various molecules including signaling molecules and cell adhesion molecules have been implicated in salivary gland development, transcription factors regulating the expression of those molecules and SMG development are largely unknown.
In the present study we show that the Grhl2 transcription factor, which is involved in development of several epithelial tissues, is expressed in the epithelial tissue of embryonic mouse submandibular gland (SMG). Grhl2 knockdown in cultured SMG results in retardation of epithelial growth and branching morphogenesis of the gland. Grhl2 binds to SPINT1 gene, which encodes a protease inhibitor functioning in the extracellular space, and positive regulates SPINT1 protein expression in the epithelial tissue. Furthermore, the addition of SPINT1 protein rescues defects in SMG development upon Grhl2 knockdown. Grhl2 and SPINT1 may be utilized for therapy and regeneration of damaged salivary glands.
