CXCR4 siRNA inhibited significantly the protein expression of CXCR4. Cells were incubated with different synthetic oligonucleotides as described in the materials and methods section, and CXCR4 protein was quantified by Western-Blot. The targeted CXCR4 siRNA inhibited significantly the protein expression of CXCR4 gene (*p <0.05).
