Identification of Key Genes and Prognostic Value Analysis in Hepatocellular Carcinoma by Integrated Bioinformatics Analysis

Expression and prognostic value of CDK1 in HCC. (a–e) The expression data collected from 4 datasets from ONCOMINE indicated that CDK1 expression was upregulated in HCC tissues compared with the normal control tissues and cells (all ). (f) Expression of CDK1 was increased in HCC cells based on the data from CCLE. (g) The Kaplan-Meier survival curves revealed that the high CDK1 expression predicted worse overall survival compared with the low CDK1 expression in HCC patients (log-rank ). (h) No significantly different survival times were observed between patients with high CDK1 expression and patients with low CDK1 expression at tumor stage 1 (log-rank ). (i) High CDK1 expression predicted worse overall survival compared with the low CDK1 expression in HCC at tumor stage 2 (log-rank ). (j) High CDK1 expression predicted worse overall survival compared with the low CDK1 expression in HCC patients at tumor stage 3 (log-rank ).
