This is a reversible process and cells can also eventually undergo mesenchymal-to-epithelial transition (MET). The existence of a dynamic EMT process suggests the involvement of epigenetic shifts in the phenotype. Herein, we obtained the DNA methylomes at single-base resolution of MDCK cells undergoing epithelial-to-mesenchymal transition (EMT) and translated the identified differentially methylated regions (DMRs) to human breast cancer cells undergoing a gain of migratory and invasive capabilities associated with the EMT phenotype. We noticed dynamic and reversible changes of DNA methylation, both on promoter sequences and gene-bodies in association with transcription regulation of EMT-related genes. Most importantly, the identified DNA methylation markers of EMT were present in primary mammary tumors in association with the epithelial or the mesenchymal phenotype of the studied breast cancer samples.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Javierre, Biola M</style></author><author><style face="normal" font="default" size="100%">Fernandez, Agustin F</style></author><author><style face="normal" font="default" size="100%">Richter, Julia</style></author><author><style face="normal" font="default" size="100%">Fatima Al-Shahrour</style></author><author><style face="normal" font="default" size="100%">Martin-Subero, J Ignacio</style></author><author><style face="normal" font="default" size="100%">Rodriguez-Ubreva, Javier</style></author><author><style face="normal" font="default" size="100%">Berdasco, Maria</style></author><author><style face="normal" font="default" size="100%">Fraga, Mario F</style></author><author><style face="normal" font="default" size="100%">O’Hanlon, Terrance P</style></author><author><style face="normal" font="default" size="100%">Rider, Lisa G</style></author><author><style face="normal" font="default" size="100%">Jacinto, Filipe V</style></author><author><style face="normal" font="default" size="100%">Lopez-Longo, F Javier</style></author><author><style face="normal" font="default" size="100%">Dopazo, Joaquin</style></author><author><style face="normal" font="default" size="100%">Forn, Marta</style></author><author><style face="normal" font="default" size="100%">Peinado, Miguel A</style></author><author><style face="normal" font="default" size="100%">Carreño, Luis</style></author><author><style face="normal" font="default" size="100%">Sawalha, Amr H</style></author><author><style face="normal" font="default" size="100%">Harley, John B</style></author><author><style face="normal" font="default" size="100%">Siebert, Reiner</style></author><author><style face="normal" font="default" size="100%">Esteller, Manel</style></author><author><style face="normal" font="default" size="100%">Miller, Frederick W</style></author><author><style face="normal" font="default" size="100%">Ballestar, Esteban</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Changes in the pattern of DNA methylation associate with twin discordance in systemic lupus erythematosus.</style></title><secondary-title><style face="normal" font="default" size="100%">Genome research</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010 Feb</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">20</style></volume><pages><style face="normal" font="default" size="100%">170-9</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Monozygotic (MZ) twins are partially concordant for most complex diseases, including autoimmune disorders. Whereas phenotypic concordance can be used to study heritability, discordance suggests the role of non-genetic factors. In autoimmune diseases, environmentally driven epigenetic changes are thought to contribute to their etiology. Here we report the first high-throughput and candidate sequence analyses of DNA methylation to investigate discordance for autoimmune disease in twins. We used a cohort of MZ twins discordant for three diseases whose clinical signs often overlap: systemic lupus erythematosus (SLE), rheumatoid arthritis, and dermatomyositis. Only MZ twins discordant for SLE featured widespread changes in the DNA methylation status of a significant number of genes. Gene ontology analysis revealed enrichment in categories associated with immune function. Individual analysis confirmed the existence of DNA methylation and expression changes in genes relevant to SLE pathogenesis. These changes occurred in parallel with a global decrease in the 5-methylcytosine content that was concomitantly accompanied with changes in DNA methylation and expression levels of ribosomal RNA genes, although no changes in repetitive sequences were found. Our findings not only identify potentially relevant DNA methylation markers for the clinical characterization of SLE patients but also support the notion that epigenetic changes may be critical in the clinical manifestations of autoimmune disease.&lt;/p&gt;</style></abstract></record></records></xml>
