ADORA2A and familial dilated cardiomyopathy: Significantchanges in the mRNA expression of LY75 and ADORA2A were foundto be associated with aberrant DNA methylation in individuals suffering from DCM.The corresponding genes LY75 and ADORA2A in zebrafish suggestthat these genes play a crucial role in the adaptive or maladaptive pathwaysinvolved in HF.
