284 Hypertension February 2015 effect of salt in a species that evolved consuming a low sodium diet and protein from a wide variety of sources, primarily vegetable, except as a neonate. For example, cysteine is essential for the synthesis of the crucial antioxidant glutathione. Absorption of cysteine by intestinal epithelial cells and neurons is regulated. Activating the μ opioid receptor inhibits cysteine uptake. Intestinal microbes convert casein to μ opioid receptor peptide agonists; bovine, compared to human, casein-derived peptides have relatively high affinity for the μ opioid receptor. Inhibition of cysteine uptake, thus decreasing glutathione synthesis may explain the greater inflammation and reactive oxygen species generation in the casein-fed rats. Increased reactive oxygen species would decrease the availability of S-adenosyl methionine available as a methyl donor for CpG methylation, possibly failing to suppress transcription of many of the genes found to be upregulated in this study. 10The transcriptome analysis in this study clearly demonstrates hazards of comparing animals from different sources. Contradictory information derived from diverse inbred Dahl SS colonies resulting from genetic differences is but one example. 11 Although the genetic differences identified between the SS/Mcw and SS/Crl in this study did not affect salt sensitivity of the blood pressure or renal pathology, they may well be germane to others processes. The SS/Mcw genome has been sequenced and numerous congenic and knockout strains have been developed on its background. The value of these important resources would be greatly diminished if the parental strain were no longer available to the scientific community. Therefore, the SS/Crl (SS/McwCrl) commercial breeding colony should be rederived to reflect the genetics of the current SS/Mcw strain before its continued use as the wild type for genetically manipulated SS/Mcw rats. The results presented by Geurts et al4 also demonstrate that it is imperative to consider the environment throughout the lives of animals to be compared. Because of space constraints and colony maintenance costs, it is not uncommon to purchase wild-type animals. We now have ample evidence that comparing genetically modified animals from an institutional colony to commercially obtained parental stock fed different diets and subjected to the stress of shipping, particularly at the vulnerable
