Abstract:
Objective To observe after the NIBP (NIK and IKK beta binding protein) gene transfected into colon cancer cell lines HT29, the migration of cells and expression of p65, MMP2, MMP9 mRNA and proteins. Methods The experimental group: divided into without transfection HT29 cell (HT29 group) and transfection no-load HT29 cell (HT29-NC group) and transfection NIBP HT29 cell (HT29-NIBP steady group). Using the Transwell test to detect cell migration ability. Q-PCR method to detect the mRNA expressions of NIBP , p65, MMP2, MMP9. Western Blot method to detect the expressions of NIBP, p65, phosphorylation p65 (p-p65) proteins. The method of ELISA was used to detect the secretion of matrix metalloproteinase (MMP)-2, MMP-9. Results The high expression of NIBP may enhance the migration ability of colon cancer cell lines HT29 , increasing the expression of p-p65, MMP2, MMP9 mRNA and proteins (P < 0.05). Conclusion NIBP potently enhances colon cancer HT29 cell migration and invasion. Activation of NF-κB signaling pathways resulted in up-regulation of MMP-2 and MMP-9 maybe one of its molecular mechanisms.
