长链非编码RNA (lncRNA) LINC00152,也被称为CYTOR,在各种癌症中表现出异常表达。然而,其在乳腺癌中的临床价值和功能机制尚不清楚。我们的研究发现,LINC00152在乳腺癌中显著上调,并可作为生存预后不良的指标。进一步的研究表明,LINC00152基因敲低可抑制细胞增殖和体内致瘤性。机制分析表明,LINC00152直接与KLF5蛋白结合,提高KLF5的稳定性。此外,LINC00152也是一个KLF5响应的lncRNA, KLF5通过直接结合其启动子激活LINC00152的转录。我们的研究表明LINC00152通过与KLF5相互作用促进肿瘤进展。LINC00152可能是一种有价值的乳腺癌预后预测因子,而LINC00152- klf5的正反馈回路可能成为药物策略中的治疗靶点。
The long noncoding RNA (lncRNA) LINC00152, also known as CYTOR, displays aberrant expression in various cancers. However, its clinical value and functional mechanisms in breast cancer remain insufficiently understood. Our study found that LINC00152 is significantly upregulated in breast cancer, and that it acts as an indicator of poor survival prognosis. Further studies revealed that LINC00152 knockdown suppresses cell proliferation and tumorigenicity in vitro and in vivo. Mechanistic analyses demonstrated that LINC00152 directly binds to KLF5 protein and increases KLF5 stability. Moreover, LINC00152 is also a KLF5-responsive lncRNA, and KLF5 activates LINC00152 transcription by directly binding to its promoter. Our study suggests that LINC00152 promotes tumor progression by interacting with KLF5. LINC00152 may be a valuable prognostic predictor for breast cancer, and the positive feedback loop of LINC00152-KLF5 could be a therapeutic target in pharmacological strategies.
