Liver steatosis, cardiac and renal fibrosis, and hypertension in overweight rats: Angiotensin-(3-4)-sensitive hepatocardiorenal syndrome.

Overweight/obesity is a growing pandemic that affects many organs and tissues. We have investigated whether a high-lipid diet provokes an imbalance between type 1 and type 2 angiotensin II (Ang II) receptors signaling, leading to liver alterations associated with cardiovascular and kidney disturbances. Chronic administration of a high-lipid diet can provoke hepatocardiorenal syndrome resulting from activation of the Ang II→type 1 receptor axis, which is entirely counteracted by Ang-(3-4), the allosteric enhancer of the Ang II→type 2 receptor pathway.
