To study the role of DLC-1 promoter methylation in the colorectal carcinogenesis routing down the adenoma-carcinoma process, here we quantified the methylation status and mRNA expression of DLC-1 and assessed its relation to various clinicopathological parameters and molecular features, especially the mutation status of KRAS and BRAF in 185 colorectal tissue samples from different disease stages. The gene discussed is BRAF; the disease is adenoma.
