Introduction: Zinc finger homeobox 4 (ZFHX4) is a crucial molecular regulator of tumor-initiating stem cell-like functions. Objective: This study aimed to determine the role of ZFHX4 in the progression of ovarian serous cystadenocarcinoma (OSC). Methods: Differential gene expression among low-stage (stages I and II), high-stage (stages III and IV), low-grade (grades I and II), and high-grade (grades III and IV) OSC patients was identified using four independent cohorts from the Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO). We compared ZFHX4 expression as a prognostic factor using Kaplan-Meier survival curves, multivariate analysis, the time-dependent area under the curve (AUC) of Uno's C-index, and the AUC of the receiver operating characteristics at 4 years post diagnosis. Results: ZFHX4 gene expression in high-stage tumors is significantly higher than in low-stage tumors (TCGA, p = 0.007; GSE9891, p = 0.001). Kaplan-Meier analysis revealed that elevated expression of ZFHX4 was associated with a poor prognosis in OSC patients for all cohorts, regardless of stage and grade (TCGA, p = 1e-04; GSE9891, p = 0.0044; GSE13876, p = 0.00078; GSE26712, p = 0.039). Analysis of C-indices and the area under the receiver operating characteristic curve further supported this result (C-index: TCGA, 0.599; GSE9891, 0.642; GSE13876, 0.585; GSE26712, 0.597). Moreover, univariate and multivariate Cox hazards analyses confirmed the prognostic significance of ZFHX4 levels. Conclusion: Collectively, these findings suggest that ZFHX4 is a potential prognostic factor for OSC.

锌指同源异型盒4在卵巢浆液性膀胱癌中的预后作用。

简介:锌指同源盒4(ZFHX4)是启动肿瘤的干细胞样功能的关键分子调节剂。目的:本研究旨在确定ZFHX4在卵巢浆液性囊腺癌(OSC)进程中的作用。方法:鉴定低级(I和II期),高级(III和IV期),低级(I和II级)和高级(III和IV级)OSC患者之间的差异基因表达使用来自癌症基因组图谱(TCGA)和基因表达综合(GEO)的四个独立队列。我们使用Kaplan-Meier生存曲线,多变量分析,Uno C指数曲线下的时间依赖性面积(AUC)以及接受者在诊断后4年时的操作特性的AUC,将ZFHX4表达作为预后因素进行了比较。结果:ZFHX4基因在高级别肿瘤中的表达明显高于低级别肿瘤(TCGA,p = 0.007; GSE9891,p = 0.001)。Kaplan-Meier分析显示ZFHX4的升高表达与所有队列的OSC患者预后不良有关,无论其阶段和等级如何(TCGA,p = 1e-04; GSE9891,p = 0.0044; GSE13876,p = 0.00078; GSE26712 ,p = 0.039)。C指标和接收器工作特性曲线下面积的分析进一步支持了该结果(C指标:TCGA,0.599; GSE9891,0.642; GSE13876,0.585; GSE26712,0.597)。此外,单因素和多因素Cox危险性分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。GSE9891,p = 0.001)。Kaplan-Meier分析显示ZFHX4的升高表达与所有队列的OSC患者预后不良有关,无论其阶段和等级如何(TCGA,p = 1e-04; GSE9891,p = 0.0044; GSE13876,p = 0.00078; GSE26712 ,p = 0.039)。C指标和接收器工作特性曲线下面积的分析进一步支持了该结果(C指标:TCGA,0.599; GSE9891,0.642; GSE13876,0.585; GSE26712,0.597)。此外,单因素和多因素Cox危险性分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。GSE9891,p = 0.001)。Kaplan-Meier分析显示ZFHX4的升高表达与所有队列的OSC患者预后不良有关,无论其阶段和等级如何(TCGA,p = 1e-04; GSE9891,p = 0.0044; GSE13876,p = 0.00078; GSE26712 ,p = 0.039)。C指标和接收器工作特性曲线下面积的分析进一步支持了该结果(C指标:TCGA,0.599; GSE9891,0.642; GSE13876,0.585; GSE26712,0.597)。此外,单因素和多因素Cox危险性分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。p = 1e-04;GSE9891,p = 0.0044;GSE13876,p = 0.00078;GSE26712,p = 0.039)。C指标和接收器工作特性曲线下面积的分析进一步支持了该结果(C指标:TCGA,0.599; GSE9891,0.642; GSE13876,0.585; GSE26712,0.597)。此外,单因素和多因素Cox危险性分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。p = 1e-04;GSE9891,p = 0.0044;GSE13876,p = 0.00078;GSE26712,p = 0.039)。C指标和接收器工作特性曲线下面积的分析进一步支持了该结果(C指标:TCGA,0.599; GSE9891,0.642; GSE13876,0.585; GSE26712,0.597)。此外,单因素和多因素Cox危险性分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。单因素和多因素Cox危害分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。单因素和多因素Cox危害分析证实了ZFHX4水平的预后意义。结论:总的来说,这些发现表明ZFHX4是OSC的潜在预后因素。
