T-box transcription factor 15 (TBX15) plays important role in various cancers; however, its expression and role in glioma is still unclear. In this study, our findings indicated that TBX15 was increased in gliomas compared to normal brain tissues, and high levels of TBX15 were related to poor survival. Furthermore, TBX15 silencing in glioma cells not only inhibited their proliferation, migration, and invasion , but also weakened their ability to recruit macrophages and polarize the latter to the M2 subtype. Mechanism study indicated that thioredoxin domain containing 5 (TXNDC5) lies downstream of TBX15. Furthermore, rescue assays verified that the role of TBX15 in glioma cells is dependent on TXNDC5. Moreover, sh-TBX15 loaded into DNA origami nanocarrier suppressed the malignant phenotype of glioma and . Taken together, the TBX15/TXNDC5 axis is involved in the genesis and progression of glioma, and is a potential therapeutic target.
T盒转录因子15（TBX15）在多种癌症中发挥重要作用；然而，其在胶质瘤中的表达及作用仍不清楚。在本研究中，我们的研究结果表明，与正常脑组织相比，胶质瘤中TBX15表达增加，且高水平的TBX15与较差的生存率相关。此外，胶质瘤细胞中TBX15沉默不仅抑制其增殖、迁移和侵袭，还削弱其招募巨噬细胞并将后者极化为M2亚型的能力。机制研究表明，含硫氧还蛋白结构域5（TXNDC5）位于TBX15下游。此外，挽救实验证实TBX15在胶质瘤细胞中的作用依赖于TXNDC5。此外，装载到DNA折纸纳米载体中的sh-TBX15抑制了胶质瘤的恶性表型。综上所述，TBX15/TXNDC5轴参与胶质瘤的发生和发展，是一个潜在的治疗靶点。
