Objectives:
To investigate the roles of high-mobility group box 1 (HMGB1) protein in lymphangiogenesis and lymphatic node metastasis in colon cancer.
Methods:
Archival tumour specimens from patients with colon cancer were analysed in this retrospective immunohistochemical study. HMGB1, vascular endothelial growth factor C (VEGF-C) and podoplanin protein levels were analysed immunohistochemically. In vitro studies using the colon cancer cell line HCT116 were also undertaken to investigate the relationship between HMGB1, VEGF-C and nuclear factor (NF)-κB.
Results:
Specimens from 70 patients with colon cancer were reviewed. The presence of positive HMGB1 immunohistochemical staining significantly correlated with lymphatic microvessel density, lymph node metastasis and VEGF-C immunohistochemical staining in colon cancer specimens. The presence of positive VEGF-C immunohistochemical staining significantly correlated with lymph node metastasis. The in vitro studies demonstrated that HMGB1 upregulated VEGF-C mRNA and protein in a dose-dependent manner in HCT116 cells, and that this was mediated via NF-κB.
Conclusions:
HMGB1 immunohistochemical staining was significantly associated with lymphangiogenesis and lymphatic node metastasis in colon cancer. There was evidence that HMGB1 upregulates VEGF-C by activating NF-κB in a colon cancer cell line.
