黑色素瘤占皮肤癌死亡的近80%,CD147在黑色素瘤的发生发展过程中起着重要作用,其表达水平可能与肿瘤的恶性程度有关。RING1可以结合DNA并作为转录抑制因子,在黑色素瘤的侵袭性表型中发挥重要作用。用酵母双杂交鉴定CD147和RING1之间的相互作用,RING1通过跨膜区与CD147相互作用。抑制CD147‘S促进黑色素瘤细胞迁移的作用。总之,本研究发现了CD147和RING1之间新的相互作用,恢复了CD147在黑色素瘤细胞中的核膜分布,并提出了细胞质CD147促进黑色素瘤发展的新机制。
Melanoma accounts for nearly 80% of all deaths associated with skin cancer.CD147 plays a very important role in melanoma progression and the expression level may correlate with tumor malignancy. RING1 can bind DNA and act as a transcriptional repressor, play an important role in the aggressive phenotype in melanoma. The interactions between CD147 and RING1 were identified with a yeast two-hybrid and RING1 interacted with CD147 through the transmembrane domain. RING1 inhibits CD147’s capability promoting melanoma cell migration. In conclusion, the study identified novel interactions between CD147 and RING1, recovered CD147 nuclear envelope distribution in melanoma cells, and suggested a new mechanism underlying how cytoplasmic CD147 promotes melanoma development.
