This work aims to explore circ_ROBO1's function in nasopharyngeal carcinoma (NPC).
circ_ROBO1 expression in NPC tissues and cell lines was measured. The regulation of circ_ROBO1 and/or miR-324-3p on the proliferation, migration, invasion, and apoptosis of NPC cells was investigated by functional experiments. The interplay between circ_ROBO1, miR-324-3p, and NME1 was explored. Tumor growth and metastasis were studied in mice.
circ_ROBO1 was overexpressed in NPC. Knockdown of circ_ROBO1 repressed proliferation, migration, and invasion and induced apoptosis of NPC cells. Loss of circ_ROBO1 reduced tumor growth and metastasis in mice. circ_ROBO1 competed with miR-324-3p to upregulate NME1. Lowering miR-324-3p expression impaired the effect of knockdown of circ_ROBO1on NPC cells.
Overexpressed circ_ROBO1 promotes NPC development by modifying the miR-324-3p/NME1 axis.
本研究旨在探讨环状RNA_ROBO1(circ_ROBO1)在鼻咽癌(NPC)中的作用。
检测circ_ROBO1在NPC组织和细胞系中的表达。通过功能实验研究circ_ROBO1和/或miR-324-3p对NPC细胞增殖、迁移、侵袭和凋亡的调控作用。探究circ_ROBO1、miR-324-3p和NME1之间的相互作用。在小鼠体内研究肿瘤生长和转移情况。
circ_ROBO在NPC中高表达。敲低circ_ROBO1可抑制NPC细胞的增殖、迁移和侵袭,并诱导其凋亡。circ_ROBO1缺失可减少小鼠肿瘤生长和转移。circ_ROBO1与miR-324-3p竞争上调NME1。降低miR-324-3p表达可削弱敲低circ_ROBO1对NPC细胞的作用。
circ_ROBO1过表达通过调节miR-324-3p/NME1轴促进NPC进展。
