Expression of various cytokines in the IR/Ipsi-tumor, IR/Contra-tumor, and Sham-IR/Tumor groups. The expressions of CXCR4, FGF-2, VEGF-A, EGFR and ERK2 in the IR/Ipsi-tumor group were significantly higher than those in the Sham-IR/Tumor group. The expressions of CXCR4, FGF-2 and ERK2 in the IR/Contra-tumor group were significantly higher compared to those in the Sham-IR/Tumor group. These results were expressed as mean ± SD and comparisons between groups were assessed by Student’s t-test.
