Species differences in renal NO production caution against extrapolating rodent high-salt data to humans; leaves open NOS1 variant roles in human salt sensitivity.
This study demonstrates species-specific differences in the regulation of inner medullary collecting duct nitric oxide production and NOS1 splice variant expression in response to high dietary sodium.
Hyndman et al. (2013) studied this question.
