A systems-level integrative framework for genome-wide DNA methylation and gene expression data identifies differential gene expression modules under epigenetic control
2014
Bioinformatics
Preserved Fulltext
The algorithm identifies gene modules of coordinated differential methylation and differential expression in the context of a human interactome. ...
Results: Here, we present a novel functional supervised algorithm, called Functional Epigenetic Modules (FEM), for the integrative analysis of Infinium 450k DNA methylation and matched or unmatched gene ...
Similarly, FEM could be applied to cellular differentiation data to identify cell type-specific gene expression modules under the regulation of DNA methylation. ...
