ANKRD1 and myocardial infarction: Among DEGs of Cluster Red, genes such as Csrp3, Ankrd1 and Nppb (Fig. 2c), which were shared with those of Cluster 2 from the snRNA-seq analysis and were characterized by the function associated with the response to muscle stretch, were uniquely localized within the BZ of the infarcted hearts during the acute phase of MI (Fig. 2e).
