摘要: Recently, Dclk1 expression was identified to be an intestinal cancer stem cell specific biomarker in mouse models, implicating a potential role for targeting the DCLK1-postive cells as treatment colorectal cancer. Using quantitative methylation PCR (qMSP) we here demonstrated that DCLK1 promoter is hypermethylated vast majority of cancers (134/164; 82%), with no normal mucosa samples (0/106). We further showed by Affymetrix exon arrays significantly downregulated human (n = 125) compared colonic 15), which confirmed real-time RT-PCR subgroup samples. Additionally, significant negative correlation observed between and 74 lines derived from 15 different tissues, gene increased after epigenetic drug initially methylated lines. These findings underscore pot...
