Figure 1.

The expression levels of CCL4 and VEGF-A were highly expressed in the EC patients and showed positive correlation. A. The mRNA expression levels of CCL4 were detected by qRT-PCR in twenty-two tumor specimens and their corresponding normal specimens. B. VEGF-A expression was measured by qRT-PCR in twenty-two tumor specimens and their corresponding normal specimens. C. The correlation between CCL4 expression and VEGF-A expression was analyzed (r² = 0.7089, P < 0.05). D. Quantitative intensity of CCL4 was counted in the normal and tumor specimens of different clinical stages using IHC, the representative images were shown at the top from one stage IV patient. E. VEGF-A intensity was analyzed in the normal and tumor specimens of different clinical stages using IHC, the representative images were shown at the top from one stage IV patient.
