Popis: Dysregulation of lncRNAs is a critical factor in the migration and invasion of tumors. Here our study reveals that lncRNA HIF1A-AS2 is highly expressed in breast cancer tissues and various TNBC cell lines. Moreover, we present compelling evidence supporting the role of HIF1A-AS2 in promoting TNBC cell proliferation, metastasis, invasion, and resistance to paclitaxel treatment. Additionally, our transcriptome sequencing analysis identifies MRPS23 as a potential downstream target protein regulated by HIF1A-AS2 and knockdown of HIF1A-AS2 leads to decreased expression of MRPS23 in TNBC cells. Moreover, MRPS23 exhibits similar effects on enhancing cell proliferation, metastasis, invasion, and paclitaxel resistance in TNBC cells. Furthermore, downregulating HIF1A-AS2 suppresses the enhanced functionality observed in TNBC cells due to upregulated MRPS23 expression. These findings suggest that modulation of MRPS23 protein expression by HIF1A-AS2 may influence cellular processes and paclitaxel sensitivity in TNBC cells.
