Abstract:
Recent studies proved that an inactivation of RUNX3 (runt-related transcription factor-3) expression is highly associated with lymph node metastasis and poor prognosis in various cancer types. However, the mechanism of RUNX3-mediated suppression of tumor metastasis remains unclear. Herein, we aimed to clarify the effect of RUNX3 on metastasis and angiogenesis in colorectal cancer (CRC). First, we found that the reduction of expression of RUNX3 in CRC tissues when compared with tumor adjacent normal colon tissues, as indicated by reduced RUNX3 staining, was significantly correlated with TNM stage. Second, we demonstrated that RUNX3 overexpression inhibited CRC cell migration and invasion resulting from the elevated upregulation of matrix metalloproteinase-2 and -9 (MMP-2 and MMP-9) expression. In contrast, the knockdown of RUNX3 reduced the inhibition of migration and invasion of CRC cells. Last, Vascular endothelial growth factor(VEGF) is an inducer of angiogenesis and lymphangiogenesis. We found that restoration of RUNX3 decreased vascular endothelial growth factor (VEGF) secretion and suppressed endothelial cell growth and tube formation in CRC cells. Taken together, our data demonstrated that RUNX3 may provide insights into the development of RUNX3 for CRC metastasis diagnostics and therapeutics.
