The methylation levels of RUNX3 and TGF-β in metastatic vs. primary renal cancer xenograft model. a CpG methylation levels of RUNX3 and TGF-β in metastatic xenograft model was detected by using qMSP compared with primary renal xenograft cancer model (**p < 0.01). The data were mean ± SD of three independent experiments. b Global DNA methylation levels of RUNX3 and TGF-β in metastatic xenograft model were detected by using quantitative methylation real-time PCR compared with primary renal xenograft cancer model (**p < 0.01). The data were mean ± SD of three independent experiments
