Triple negative breast cancer (TNBC) is a prevalent malignant tumor in women and is characterized by high incidence and mortality. Current evidence has suggested that multiple long noncoding RNAs (lncRNAs) play regulatory roles in TNBC, while the specific mechanism of LINC01224 in TNBC remains unclear. In this study, LINC01224 was highly expressed in TNBC cells. Moreover, LINC01224 downregulation inhibited TNBC cell proliferation, migration, and invasion, and promoted cell apoptosis. Additionally, LINC01224 stabilized NUP210 mRNA through interaction with miR-193a-5p, thereby aggravating the malignant phenotypes of TNBC. Overall, LINC01224 functions as a tumor promoter for TNBC.
三阴性乳腺癌(TNBC)是女性中一种常见的恶性肿瘤,其特点是发病率和死亡率高。目前的证据表明,多种长链非编码RNA(lncRNAs)在TNBC中发挥调节作用,而LINC01224在TNBC中的具体机制仍不清楚。在本研究中,LINC01224在TNBC细胞中高表达。此外,LINC01224的下调抑制了TNBC细胞的增殖、迁移和侵袭,并促进了细胞凋亡。此外,LINC01224通过与miR-193a-5p相互作用稳定NUP210 mRNA,从而加重了TNBC的恶性表型。总体而言,LINC01224在TNBC中起肿瘤促进作用。
