SGK1 and familial dilated cardiomyopathy: Notably, SGK1 was previously related to the initiation of cardiac hypertrophy and remodeling.[24] Specifically, it was reported that during cardiac hypertrophy, alpha‐adrenergic signaling was augmented by corticosteroid partially through SGK1 upregulation.[25] After searching the Gene Expression Omnibus (GEO) database, we observed an increased trend of cardiac mRNA expression of SGK1 in patients with dilated cardiomyopathy (DCM) (GSE4172 dataset, Figure 2F), suggesting a potential role of SGK1 in the progression of heart hypertrophy.
