Figure Lengend Snippet: A A negative correlation between ZNF334 methylation level and its mRNA expression (Pearson r = −0.53, R 2 = 0.28) B mRNA expression of ZNF334 in cancer and adjacent tissues of 213 liver cancer patients. C Western-blot diagram of ZNF334 expression in cancer and adjacent tissues of 12 liver cancer patients. D Methylation mass spectrum primers of ZNF334 promoter region and mass spectrometry detection product sequence (green indicates the EPIC chip probe cg07139762 site, which is in the ZNF334 promoter region; yellow indicates the MassARRAY methylation mass spectrometry detection sites, a total of 29). E Heat map of methylation level of ZNF334 promoter region in cancer and adjacent tissues of 25 patients with liver cancer. F The ratio of methylation degree of ZNF334 promoter in cancer and adjacent tissues (T/P) of 25 patients with liver cancer. G The average methylation degree of ZNF334 promoter in cancer and adjacent tissues of 25 patients with liver cancer. **** p < 0.0001.
Article Snippet: And meanwhile, in clinical samples, we used MassArray Sequenom detection to further verify the DNA methylation changes of ZNF334 promoter in cancerous tissues and adjacent tissues.
