Different blood pressure responses in hypertensive rats following chemerin mRNA inhibition in dietary high fat compared to dietary high-salt conditions.

ABSTRACT: Chemerin is a contractile adipokine, produced in liver and fat, and removal of the protein by antisense oligonucleotides (ASO) lowers blood pressure in the normal Sprague Dawley rat. In humans, chemerin is positively associated with blood pressure and obesity so we hypothesized that in a model of hypertension derived from high-fat (HF) feeding, the chemerin ASO would reduce blood pressure more than a high-salt (HS) model. Male Dahl S rats were given a HF (60% kcal fat; age 3-24 wk) or HS diet (4% salt; age 20-24 wk to match age and blood pressure of HF animals). Scrambled control, whole body, or liver-specific ASOs that knock down chemerin were delivered subcutaneously once per week for 4 wk with tissue and blood collected 2 days after the last injection. Conscious blood pressure was measu
