Objective: Discuss the different of the genome-wide methylation research of malignant liver cancer cells which treated with the Centipede Scolopendra extraction(CSE) with the whole genome DNA methylation chip and analyse the differences of gene expression profile chip with gene annotation system (gene ontology, GO).Methods: The cellular proliferation was assessed with MTS in liver cancer cells HCCLM3 used with the CSE.Calculate the ICs0 alue concentration.CSE sequential processing with 1/2 ICs0 con-centration of the cells in 3 d, blank comp...
