主 题：zinc finger protein 554 endometrial carcinoma RNA binding motif 5 Wingless/β-catenin signaling pathway
摘 要：Objective:Uterine corpus endometrial carcinoma(UCEC),a kind of gynecologic malignancy,poses a significant risk to women’s *** precise mechanism underlying the development of UCEC remains *** finger protein 554(ZNF554),a member of the Krüppel-associated box domain zinc finger protein superfamily,was reported to be dysregulated in various illnesses,including malignant *** study aimed to examine the involvement of ZNF554 in the development of ***:The expression of ZNF554 in UCEC tissues and cell lines were examined by qRT-PCR and Western blot *** with stably overexpressed or knocked-down ZNF554 were established through lentivirus ***-8,wound healing,and Transwell invasion assays were employed to assess cell proliferation,migration,and *** iodide(PI)staining combined with fluorescence-activated cell sorting(FACS)flow cytometer was utilized to detect cell cycle ***-PCR and Western blotting were conducted to examine relative mRNA and protein *** immunoprecipitation assay and luciferase reporter assay were used to explore the regulatory role of ZNF554 in RNA binding motif 5(RBM5).Results:The expression of ZNF554 was found to be reduced in both UCEC samples and cell *** expression of ZNF554 was associated with higher tumor stage,decreased overall survival,and reduced disease-free survival in ***554 overexpression suppressed cell proliferation,migration,and invasion,while also inducing cell cycle *** contrast,a decrease in ZNF554 expression resulted in the opposite ***,ZNF554 transcriptionally regulated RBM5,leading to the deactivation of the Wingless(WNT)/β-catenin signaling ***,the findings from rescue studies demonstrated that the inhibition of RBM5 negated the impact of ZNF554 overexpression onβ-catenin and p-glycogen synthase kinase-3β(p-GSK-3β).Similarly,the deliberate activation of RBM5 reduced the increase inβ-catenin and
