Aim To explore the effect of stromal cell derived factor 1α--CXCR4 (SDF-1α--CXCR4) on THP-1 cells chemotaxis, the influence of oxidized low density hpoprotein (ox-LDL) on THP-1 cells migration exposed to SDF-1α, and the effect of ox-LDL on the expression of CXCR4 in THP-1 cell. Methods THP-1 cells chemotaxis was examined with transwell permeable supports. CXCR4 mRNA and protein was revealed by RT-PCR and Western blot respectively in THP-1 cells incubated with different concentrations/time of ox-LDL. Results SDF-1α induced a pronounced m...
