PADI2 was upregulated in ovarian cancer samples and high PADI2 expression was correlated with poor outcome. a Analysis of PADI2 expression level in human OC. Gene Expression Profiling Interactive Analysis (GEPIA) showed that the red and gray boxes represent cancer and normal tissues, respectively. b Box plots derived from gene expression data in Oncomine comparing expression of PADI2 gene in normal tissue (left plot) and ovarian cancer tissue (right plot). c Kaplan–Meier survival statistics analysis for the relationship between survival time and PADI2 signature in ovarian cancer was performed by using the online tool (https://kmplot.com/analysis/).*P < 0.05, **P < 0.01 and ***P < 0.001 compared with control group
