Identification of coexistence of DNA methylation and H3K27me3 specifically in cancer cells as a promising target for epigenetic therapy.

abstract：:The objective was to study the relationship between cyclin D1 gene (CCND1) polymorphism and lung cancer in the Chinese population. Blood samples of 182 cases and 185 controls were collected from a hospital based case-control study. PCR-SSCP was used to examine the G/A polymorphism in exon 4 of CCND1. The results showe...
