Previously, we observed population differences in cytosine modifications between Caucasian and African lymphoblastoid cell lines (LCLs) on the autosomes using whole genome arrays to measure modified cytosines. DNA methylation plays a critical role in establishment and maintenance of X-chromosome inactivation in females. Therefore, we reasoned that by investigating cytosine modification patterns specifically on the X-chromosome, we could obtain valuable information about a chromosome that is often disregarded in genome-wide analyses. We investigated population differences in cytosine modification patterns along the X-chromosome between Caucasian and African LCLs and identified novel sites that escape methylation on the inactive X-chromosome (Xi) in females. We characterized the chromatin state of these loci by incorporating the extensive histone modification ChIP-seq data generated by ENCODE. To explore the relationship between DNA and histone modifications further, we hypothesized that BRD4, a protein that binds acetylated histones, could be preventing some sites from becoming \u003ci\u003ede novo\u003c/i\u003e methylated. To test this, we treated 4 female LCLs with JQ1, a small molecule inhibitor of BRD4, but found that JQ1 treatment induced minor changes in cytosine modification levels, and the majority of sites escaping methylation on the Xi remained unmethylated. This suggests that other epigenetic mechanisms or transcription factors are likely playing a larger role in protecting these sites from \u003ci\u003ede novo\u003c/i\u003e methylation on the Xi.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
