Effect of etamicastat (ETA) treatment on dopamine β-hydroxylase (DβH) activity in adrenal glands of salt-inducible kinase 1 (SIK1) knockout (sik1−/−) mice challenged with a high-salt (8% NaCl) diet. Mean ± SEM; n = 7 to 8 per group; values were determined to be significantly different from high-salt diet group (*P < 0.05) by unpaired t test
