CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric carcinoma

Figure 5 Stable expression of CXCR7 in human SGC7901 cells. A: Western blot assay showed increased CXCR7 expression in stable CXCR7-overexpressing human SGC7901 cells compared with the untreated control group and blank vector transfection control group; B: PCR assay showed the same results as the Western blot assay; C: Western blot assay showed decreased endogenous CXCR7 expression in stable CXCR7-silenced human SGC 7901 cells compared with the untreated control group and blank vector transfection control group; β-actin was used as an internal control; D: PCR assay showed the same results as the Western blot assay. ^aP < 0.05, vs the control and vector groups. The data are presented as the mean ± SD; n = 4; bars indicate SD, P < 0.05.
