Notch信号是进化上保守的细胞间通讯途径,在哺乳动物细胞的增殖、存活、凋亡和命运决定中起着关键作用。视网膜色素上皮(RPE)细胞负责支持神经视网膜的功能和维持视力。本研究探讨了Notch信号在RPE细胞中的作用。我们发现Notch信号通路的成员在RPE细胞中有差异表达。此外,阻断Notch信号转导抑制RPE细胞的迁移和增殖,并降低某些Notch信号转导靶基因的表达水平,包括HES1、MYC、HEY2和SOX9。我们的数据揭示了Notch信号在RPE细胞中的关键作用,提示靶向Notch信号可能为治疗与RPE细胞相关的眼科疾病提供了一种新的途径。
The Notch signaling is an evolutionarily conserved cell-cell communication pathway that plays critical roles in the proliferation, survival, apoptosis, and fate determination of mammalian cells. Retinal pigment epithelial (RPE) cells are responsible for supporting the function of the neural retina and maintaining vision. This study investigated the function of Notch signaling in RPE cells. We found that the members of the Notch signaling pathway components were differentially expressed in RPE cells. Furthermore, blockage of Notch signaling inhibited the migration and proliferation of RPE cells and reduced the expression levels of certain Notch signaling target genes, including HES1, MYC, HEY2, and SOX9. Our data reveal a critical role of Notch signaling in RPE cells, suggesting that targeting Notch signaling may provide a novel approach for the treatment of ophthalmic diseases related to RPE cells.
