Thioredoxin-interacting protein (TXNIP) is commonly considered a master regulator of cellular oxidation, regulating the expression and function of Thioredoxin (Trx). Recent work has identified that TXNIP has a far wider range of additional roles: from regulating glucose and lipid metabolism, to cell cycle arrest and inflammation. Its expression is increased by stressors commonly found in neoplastic cells and the wider tumor microenvironment (TME), and, as such, TXNIP has been extensively studied in cancers. In this review, we evaluate the current literature regarding the regulation and the function of TXNIP, highlighting its emerging role in modulating signaling between different cell types within the TME. We then assess current and future translational opportunities and the associated challenges in this area. An improved understanding of the functions and mechanisms of TXNIP in cancers may enhance its suitability as a therapeutic target.
硫氧还蛋白相互作用蛋白 (TXNIP) 通常被认为是细胞氧化的主要调节剂,调节硫氧还蛋白 (Trx) 的表达和功能。最近的研究表明,TXNIP 具有更广泛的其他作用:从调节葡萄糖和脂质代谢,到细胞周期停滞和炎症。它的表达被肿瘤细胞和更广泛的肿瘤微环境 (TME) 中常见的应激源所增加,因此,TXNIP 在癌症中得到了广泛的研究。在这篇综述中,我们评估了关于 TXNIP 的调节和功能的现有文献,强调了它在调节肿瘤微环境中不同细胞类型之间信号转导方面的新兴作用。然后,我们评估了该领域当前和未来的转化机会及其相关挑战。对 TXNIP 在癌症中的功能和机制的更好理解可能会增强其作为治疗靶点的适用性。
