Abstract:
Objective To investigate the expression of CKS1B in endometrial carcinoma(EC)and its relationship with clinicopathological features and prognosis.Methods The expression profile data and clinical data of CKS1B from the TCGA and GTEx databases were downloaded to investigate the expression of CKS1B in EC and its relationship with clinicopathological features.The expression of CKS1B at the protein level was verified using the UALCAN database.The relationship between CKS1B expression and clinicopathological parameters was analyzed by Logistic regression.The r program perform enrichment analysis on CKS1B co-expressed genes in the TCGA database.Finally,CKS1B mRNA expression was discovered in the cell lines Ishikawa and HEC-1-A by quantitative real-time PCR(qRT-PCR).CKS1B protein expression was detected in EC tissues and adjacent tissues by Western Bolt(WB).Results CKS1B mRNA and protein were remarkably higher in EC tissues than in normal endometrium,and the differences were statistically significant(P<0.05).The level of CKS1B mRNA expression was strongly correlated with FIGO stage(F=42.994),histological grade(F=70.350),histological type(F=87.341)and age(F=40.097)(all P<0.05).The results of the Kaplan-Meier method showed that patients with high CKS1B mRNA expression had a lower overall survival rate(Log-rank x2=1.175,P<0.01).Multifactorial COX analysis showed that FIGO stage(HR=3.065,95%CI:1.906~4.926)and CKS1B expression(HR=1.856,95%CI:1.154~2.985)were independent risk factors affecting the prognosis of patients with EC(P<0.05).GO analysis showed that CKS1B was mainly involved in nuclear division and chromosome separation.KEGG analysis showed it was mainly enriched in the cell cycle,spliceosome and DNA replication.Further verification showed that CKS1B mRNA was highly expressed in Ishikawa and HEC-1-A cell lines(F=44.560,P<0.001),CKS1B protein was highly expressed in EC tissues(t=14.900,P<0.001).Conclusion CKS1B is upregulated in EC and is linked to clinicopathological variables in the patients.It may play a role in the development of EC by regulating the cell cycle,and it is expected to be a new marker for the diagnosis and prognosis of EC.
