Abstract excerpt
Waardenburg syndrome (WS) is associated with neural crest-derived melanocyte deficiency caused by mutations in either one of three transcription factors: MITF, PAX3, and SOX10. However, the hierarchical relationship of these transcription factors is largely unknown. We show that SOX10 is capable of transactivating the MITF promoter 100-fold, and that this transactivation is further stimulated by PAX3. Promoter...
