Abstract
- To investigate the effects and mechanism of CCL2 on the migration and invasion of human leukemia cell THP-1.The CCL2 gene was recombined with the transfer plasmid-PLVX and transfected into THP-1 cells. The CCL2 expression at RNA level was detected by RT-PCR, the CCL2 expression at protein level was determined by Western blot and ELISA, the influence of overexpression of CCL2 recombinant protein and THP-1 cells on the migration and invasion ability of THP-1 cells was analyzed by transwell migration and invasion tests, the PCR-array of migration-related cytokines was used to clarify the patential mechanism.With the Trans-Matrigel assay, the concentration of CCL2 in THP-1 transfected with CCL2 in the upper cells was higher than that in the lower cells, meanwhile, the invasion ability of CCL2-transfected THP-1 cells decreased. Increasing recombinant protein of CCL2 (rpCCL2) in the lower cells promoted migration of THP-1 cells. Migration RT2 profiler PCR array showed that the cells treated with rpCCL2 had higher levels of expression of CCL2, EPX, SPP1, CX3CL1 and CXCL13, as compared with control group.CCL2 affects the migration and invasion of THP-1 by autosecreting a series of inflammatory chemokines.
