Expression correlation analysis and survival analysis of UBE2I with genes in the UBE2I-involved protein–protein interaction network. a The UBE2I-involved protein–protein interaction network constructed by STRING database. b The expression relationship between UBE2I and PIAS1 in HCC assessed by GEPIA database. c The expression relationship between UBE2I and NSMCE2 in HCC assessed by GEPIA database. d The expression relationship between UBE2I and SAE1 in HCC assessed by GEPIA database. e The expression relationship between UBE2I and RANBP2 in HCC assessed by GEPIA database. f The expression relationship between UBE2I and UBA2 in HCC assessed by GEPIA database. g The expression relationship between UBE2I and PIAS4 in HCC assessed by GEPIA database. h The expression relationship between UBE2I and RANGAP1 in HCC assessed by GEPIA database. i The expression relationship between UBE2I and SUMO3 in HCC assessed by GEPIA database. j The expression relationship between UBE2I and SUMO1 in HCC assessed by GEPIA database. k The expression relationship between UBE2I and SUMO2 in HCC assessed by GEPIA database. P-value < 0.05 was considered as statistically significant. l The prognostic values (OS, overall survival) of the 10 correlated genes of UBE2I in HCC determined by Kaplan–Meier plotter. m The prognostic values (RFS, relapse free survival) of the 10 correlated genes of UBE2I in HCC determined by Kaplan–Meier plotter. Red bars indicated unfavorable prognosis; black represented no statistical significance. Logrank P-value < 0.05 was considered as statistically significant
