主 题：cyclin F kidney renal clear cell carcinoma clinical outcome cyclin-dependent kinase 1 senescence
摘 要：Objective Kidney renal clear cell carcinoma(KIRC)is a common renal malignancy that has a poor *** a member of the F box family,cyclin F(CCNF)plays an important regulatory role in normal tissues and ***,the underlying mechanism by which CCNF promotes KIRC proliferation still remains *** Bioinformatics methods were used to analyze The Cancer Genome Atlas(TCGA)database to obtain gene expression and clinical prognosis *** CCK8 assay,EdU assay,and xenograft assay were used to detect cell *** cell senescence and potential mechanism were assessed by SA-β-gal staining,Western blotting,as well as *** Our data showed that CCNF was highly expressed in KIRC ***,downregulation of CCNF inhibited cell proliferation in vivo and in *** studies showed that the reduction of CCNF promoted cell senescence by decreasing cyclin-dependent kinase 1(CDK1),increasing the proinflammatory factors interleukin(IL)-6 and IL-8,and then enhancing the expression of p21 and *** We propose that the high expression of CCNF in KIRC may play a key role in tumorigenesis by regulating cell ***,CCNF shows promise as a new biomarker to predict the clinical prognosis of KIRC patients and as an effective therapeutic target.
