β-Adrenergic receptor (β-AR) is downregulated in compensated hypoplastic left heart syndrome (C-HLHS, n = 4) and decompensated (D)-HLHS (n = 7) compared with non-failing right ventricle (NF-RV, n = 6). (A) Total β-AR (Bmax) is decreased in HLHS as determined by [125I]-iodocyanopindolol binding assay. The decrease of β-AR in both HLHS groups is due to (B) β1-AR downregulation with (C) preserved β2-AR expression. Results are presented as the mean with the standard error (error bars).
