Besides, the analysis of two datasets in GEO (GSE76633 and GSE74048) revealed that CEP55 was also positively related to the expression of MKI67 (encoding Ki67 protein, a cell proliferation marker) (R = 1.000, P <0.001), indicating that CEP55 may play a promoter role in the malignant proliferation of gallbladder cancer (Figure 3G). Here, MKI67 is linked to gallbladder cancer.
