| Summary: | Extracellular matrix metalloproteinase inducer (EMMPRIN) exhibits overexpression in various cancers and promotes cancer progression and metastasis via the interaction with its associated molecules. The scFv-M6-1B9 intrabody has a potential ability to reduce EMMPRIN cell surface expression. However, the subsequent effect of scFv-M6-1B9 intrabody-mediated EMMPRIN abatement on its related molecules, α3β1-integrin, MCT1, MMP-2 and MMP-9, is undefined. Our results demonstrated that the scFv-M6-1B9 intrabody efficiently decreased α3β1-integrin cell surface expression levels. In addition, intracellular accumulation of MCT1 and lactate were increased. These results lead to suppression of features characteristic for tumor progression, including cell migration, proliferation and invasion, in a colorectal cancer cell line (Caco-2) although there was no difference in MMP expression. Thus, EMMPRIN represents an attractive target molecule for the disruption of cancer proliferation and metastasis. An scFv-M6-1B9 intrabody-based approach could be relevant for cancer gene therapy. © 2014 Nature America, Inc. All rights reserved. |
