Thioredoxin-interacting protein (TXNIP) is a crucial thioredoxin-binding protein that is recognized as a tumor suppressor in diverse malignancies, such as breast cancer, lung cancer, hepatocellular carcinoma, and thyroid cancer. However, the specific role and molecular mechanisms of TXNIP in the pathogenesis and progression of pancreatic cancer cells have not been determined. In this study, we investigate the relationship between TXNIP expression and overall survival prognosis in pancreatic cancer patients. Mechanistic studies are conducted to reveal the role of TXNIP in pancreatic cancer cell proliferation, migration, and regulation during malignancy. Our findings indicate that patients with high TXNIP expression have a more favorable prognosis. experiments with pancreatic cell lines show that overexpression of TXNIP suppresses the proliferation and migration of pancreatic cancer cells. Furthermore, we find that TXNIP inhibits the activation of the MAPK signaling pathway, thereby decreasing the malignant potential of pancreatic cancer. In conclusion, our study reveals TXNIP as a promising new predictive marker and therapeutic target for pancreatic cancer.
硫氧还蛋白相互作用蛋白(TXNIP)是一种关键的硫氧还蛋白结合蛋白,在多种恶性肿瘤中被视为肿瘤抑制因子,如乳腺癌、肺癌、肝细胞癌和甲状腺癌。然而,TXNIP在胰腺癌细胞发病机制和进展中的具体作用及分子机制尚未明确。在本研究中,我们调查了TXNIP表达与胰腺癌患者总生存预后之间的关系。进行了机制研究以揭示TXNIP在胰腺癌细胞增殖、迁移及恶性过程调控中的作用。我们的研究结果表明,TXNIP高表达的患者预后更佳。胰腺细胞系实验表明,TXNIP过表达可抑制胰腺癌细胞的增殖和迁移。此外,我们发现TXNIP抑制MAPK信号通路的激活,从而降低胰腺癌的恶性潜能。总之,我们的研究揭示TXNIP是一种有前景的胰腺癌新预测标志物和治疗靶点。
