Circular RNAs (circRNAs) have been reported to exert critical roles in human cancers. In this study, we investigated the role and molecular mechanism of hsa_circ_0012673 in breast cancer. Herein, we found that the expression of hsa_circ_0012673 was upregulated in breast cancer tissues and cell lines. Knockdown of hsa_circ_0012673 using RNA interference technique suppressed the proliferation, migration, and invasion of breast cancer cells. Mechanistically, hsa_circ_0012673 sponged miR-576-3p to stabilize SRY-box transcription factor 4 (SOX4), and thereby facilitating breast cancer cell proliferation, migration and invasion. Collectively, our study identified the oncogenic properties of hsa_circ_0012673/miR-576-3p/SOX4 axis in breast cancer, providing potential and exploitable diagnostic and therapeutic molecules for breast cancer.
据报道，环状RNA（circRNAs）在人类癌症中发挥着关键作用。在本研究中，我们调查了hsa_circ_0012673在乳腺癌中的作用及其分子机制。在此，我们发现hsa_circ_0012673在乳腺癌组织和细胞系中表达上调。使用RNA干扰技术敲低hsa_circ_0012673可抑制乳腺癌细胞的增殖、迁移和侵袭。机制上，hsa_circ_0012673作为miR-576-3p的海绵，稳定了SRY盒转录因子4（SOX4），从而促进乳腺癌细胞的增殖、迁移和侵袭。总的来说，我们的研究确定了hsa_circ_0012673/miR-576-3p/SOX4轴在乳腺癌中的致癌特性，为乳腺癌提供了潜在的、可利用的诊断和治疗分子。
