TGF resetting was calculated as the difference in ΔPSF on a normal salt diet (NSD) minus ΔPSF on a high-salt diet (HSD). Dahl SS have an attenuated TGF response compared to SHR, even when fed a normal salt diet. ###P < 0.001, Dahl SS normal salt vs. SHR normal salt. Furthermore, when fed a high-salt diet for two weeks, the difference between strains becomes even greater. This is because high salt attenuates the response in both strains, but to a greater extent in Dahl SS. ***P < 0.001, TGF resetting in Dahl SS vs. TGF resetting in SHR.
