Abstract:
Objective To explore the role of menin in regulation of SOX4 gene expression. Methods Reporter gene vectors with SOX4 promoter were constructed,and the influence of menin on SOX4 gene promoter activity was analyzed by dual-luciferase reporter gene assay system.Real-time PCR was employed to detect the expression of SOX4 gene in mef cells of MEN1-/-mice and wild-type mef cells. Results Compared with wild-type mef cells,the SOX4 gene promoter activity was significantly higher in mef cells of MEN1-/-mice.After MEN1 gene was transfected into mef cells of MEN1-/-mice,the SOX4 gene promoter activity significantly descreased.The expression of SOX4 gene in mef cells of MEN1-/-mice was 2.5 time higher than that in wild-type mef cells. Conclusion Menin can inhibit the expression of SOX4 gene.
