Genome‑wide analysis of DNA methylation and gene expression changes in an ovalbumin‑induced asthma mouse model.

ABSTRACT: The aim of the present study was to establish an integrated network of DNA methylation and RNA expression in an ovalbumin (OVA)‑induced asthma model, and to investigate the epigenetically‑regulated genes involved in asthma development. Genome‑wide CpG‑DNA methylation profiling was conducted through the use of a methylated DNA immunoprecipitation microarray and RNA sequencing was performed using three lung samples from mice with OVA‑induced asthma. A total of 35,401 differentially methylated regions (DMRs) were identified between mice with OVA‑induced asthma and control mice. Of these, 3,060 were located in promoter regions and 370 of the genes containing these DMRs demonstrated an inverse correlation between methylation and gene expression.
