ABSTRACT
Neural crest (NC) cells are a multipotent cell population with powerful migration ability during development. C-X-C chemokine receptor type 4 (CXCR4) is a chemokine receptor implicated to mediate NC migration in various species, whereas the underlying mechanism is not well documented yet. PAX3 is a critical transcription factor for the formation of neural crest and the migration and differentiation of NCs. In this study, we retrieved a potential PAX3 binding element in the promoter of the CXCR4 gene, and we further found that PAX3 could promote the expression of CXCR4 and facilitate the migration of NCs. We finally demonstrated that PAX3 could bind the promoter region of CXCR4 and increase CXCR4 transcription by luciferase assay and electrophoretic mobility shift assay (EMSA). These findings suggested that PAX3 is a pivotal modulator of NC migration via regulating CXCR4 expression.
