Core Tip |
Based on the idea that S-phase kinase-associated protein 2 (Skp2) and p27kip1 might play a role in the pathogenesis and disease progression of patients with extrahepatic cholangiocarcinoma, immunohistochemical staining for Skp2, cyclin-dependent kinases regulatory subunit 1 (Cks1), p27kip1, and Ki67, along with other relevant molecular biologic experiments, were performed in tissue samples and human cholangiocarcinoma cell lines. Higher immunostaining intensity of Skp2 was an independent prognostic factor in patients with extrahepatic cholangiocarcinoma, and exogenous epidermal growth factor upregulates mRNA and protein levels of Skp2/Cks1 and p27kip1 in SNU-1196, SNU-1079, and SNU-245 cells. By chromatin immunoprecipitation assay, we found that E2F1 transcription factor directly binds to the promoter site of Skp2. |
