Global cardiac gene expression in left ventricles from 20 day-old and 60 day-old Efnb1 CMspe KO and WT male mice

To identify a physiologic postanal transcriptomic program between postnatal day 20 and 60, we first analyzed the gene expression profile in 60 day-old ( young adult) wild-type mice (WT) and compared it to 20 day-old WT mice To identify the gene expression between postnatal day 20 and 60 under the strict dependence of cardiac ephrin-B1, we compared gene expression in 20 day-old and 60 day-old Efnb1 CMspe KO (a-MHC-Cre-/+ Efnb1 flox/flox or) to 20 day-old and 60 day-old WT mice There are 23 Cardiac left ventricle samples, each from an individual mouse. The samples (left ventricles) are from Efnb1 cardiac KO (Efnb1cKO) and WT male mice of 20 day-old or 60 day-old from the same genetic background (mixed S129/S4 × C57BL/6). N=6 mice for P20 (postnatal day 20 - 20 day-old) WT and Efnb1 cKO genotypes , n=6 for P60 Efnb1 cKO genotype, n=5 for P60 WT genotype,
