Abstract

How high salt intake increases blood pressure is a key question in the study of hypertension. Salt intake induces increased renal sympathetic activity resulting in sodium retention. However, the mechanisms underlying the sympathetic control of renal sodium excretion remain unclear. In this study, we found that β(2)-adrenergic receptor (β(2)AR) stimulation led to decreased transcription of the gene encoding WNK4, a regulator of sodium reabsorption. β(2)AR stimulation resulted in cyclic AMP-dependent inhibition of histone deacetylase-8 (HDAC8) activity and increased histone acetylation, leading to binding of the glucocorticoid receptor to a negative glucocorticoid-responsive element in the promoter region. In rat models of salt-sensitive hypertension and sympathetic overactivity, salt loading suppressed renal WNK4 expression, activated the Na(+)-Cl(-) cotransporter and induced salt-dependent hypertension. These findings implicate the epigenetic modulation of WNK4 transcription in the development of salt-sensitive hypertension. The renal β(2)AR-WNK4 pathway may be a therapeutic target for salt-sensitive hypertension.

  • In a rat model of salt-sensitive hypertension, stimulation of sympathetic signalling reduces expression of WNK4 owing to hyper-acetylation of its promoter.

    “In a rat model of salt-sensitive hypertension, stimulation of sympathetic signalling led to reduced expression of a regulator of sodium reabsorption, protein kinase lysine-deficient 4 (WNK4), owing to hyper-acetylation of the promoter198.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
