在本研究中,我们研究了转录因子RUNX2在黑色素瘤发生中的作用。我们证明,与人类黑素细胞相比,黑色素瘤细胞系中转录活性RUNX2的表达增加。使用黑色素瘤组织微阵列,我们表明,RUNX2水平较高,在黑色素瘤细胞相比,痣黑色素细胞。在黑色素瘤细胞系中,RUNX2敲低显著降低了粘着斑激酶的表达,并抑制了其细胞生长、迁移和侵袭能力。最后,前激素胆钙化醇降低了RUNX2的转录活性,并减少了黑素瘤细胞的迁移,进一步表明RUNX2在黑素瘤细胞迁移中的作用。
In the present study, we investigated the role of the transcription factor RUNX2 in melanomagenesis. We demonstrated that the expression of transcriptionally active RUNX2 was increased in melanoma cell lines as compared with human melanocytes. Using a melanoma tissue microarray, we showed that RUNX2 levels were higher in melanoma cells as compared with nevic melanocytes. RUNX2 knockdown in melanoma cell lines significantly decreased Focal Adhesion Kinase expression, and inhibited their cell growth, migration and invasion ability. Finally, the pro-hormone cholecalciferol reduced RUNX2 transcriptional activity and decreased migration of melanoma cells, further suggesting a role of RUNX2 in melanoma cell migration.
