In this study, we aimed to identify DNA methylation sensitive genes in the ischaemic heart and elucidate their role in cardiac fibrosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A multi-omics integrative analysis was carried out on RNA sequencing and methylation sequencing on HF with IHD (n = 9) versus non-failing (n = 9) left ventricular tissue, which identified Integrin beta-like 1 (ITGBL1) as a gene of interest. Expression of Itgbl1 was assessed in three animal models of HF; an ischaemia-reperfusion pig model, a myocardial infarction mouse model and an angiotensin-II infused mouse model. Single nuclei RNA sequencing was carried out on heart tissue from angiotensin-II infused mice to establish the expression profile of Itgbl1 across cardiac cell populations. Subsequent in vitro analyses were conducted to elucidate a role for ITGBL1 in human cardiac fibroblasts. DNA pyrosequencing was applied to assess ITGBL1 CpG methylation status in genomic DNA from human cardiac tissue and stimulated cardiac fibroblasts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>ITGBL1 was &amp;gt;2-fold up-regulated (FDR adj P = 0.03) and &amp;gt;10-fold hypomethylated (FDR adj P = 0.01) in human HF with IHD left ventricular tissue compared with non-failing controls. Expression of Itgbl1 was up-regulated in three isolated animal models of HF and showed conserved correlation between increased Itgbl1 and diastolic dysfunction. Single nuclei RNA sequencing highlighted that Itgbl1 is primarily expressed in cardiac fibroblasts, while functional studies elucidated a role for ITGBL1 in cardiac fibroblast migration, evident in 50% reduced 24 h fibroblast wound closure occurring subsequent to siRNA-targeted ITGBL1 knockdown. Lastly, evidence provided from DNA pyrosequencing supports the theory that differential expression of ITGBL1 is caused by DNA hypomethylation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>ITGBL1 is a gene that is mainly expressed in fibroblasts, plays an important role in cardiac fibroblast migration, and whose expression is significantly increased in the failing heart.
