EpiMix
is a comprehensive tool for the integrative analysis of high-throughput DNA methylation data and gene expression data. EpiMix
enables automated data downloading (from TCGA or GEO), preprocessing, methylation modeling, interactive visualization and functional annotation.To identify hypo- or hypermethylated CpG
sites across physiological or pathological conditions, EpiMix
uses a beta mixture modeling to identify the methylation states of each CpG
probe and compares the methylation of the experimental group to the control group.The output from EpiMix
is the functional DNA methylation that is predictive of gene expression. EpiMix
incorporates specialized algorithms to identify functional DNA methylation at various genetic elements, including proximal cis-regulatory elements of protein-coding genes, distal enhancers, and genes encoding microRNAs
and lncRNAs
