title: CD147 depletion down-regulates matrix metalloproteinase-11, vascular endothelial growth factor-A expression and the lymphatic metastasis potential of murine hepatocarcinoma Hca-F cells.
abstract: Extracellular matrix metalloproteinase inducer (EMMPRIN, CD147), which is a plasma membrane glycoprotein enriched on the surface of many malignant tumors promotes adhesion, invasion and metastasis of tumor cells. In addition, tumor-associated CD147 also induces vascular endothelial growth factors (VEGFs) expression. To investigate the possible role of CD147 in the mouse hepatocarcinoma cell line Hca-F with highly metastatic potential in the lymph nodes, we used an RNA interference (RNAi) approach to silence CD147 expression. The results showed that CD147 depletion in Hca-F cells resulted in the significantly decreased expression of matrix metalloproteinase-11 (MMP-11), VEGF-A at both mRNA and protein levels. The reduced CD147 expression also attenuated the invasive, adhesive, metastatic ability of Hca-F cells to lymph nodes both in vitro and in vivo. Our current findings reveal that the tumor biological marker CD147 functionally mediates MMP-11, VEGF-A expression and tumor lymphatic metastasis.
