Plasma mtDNA developed a positive gradient across the kidney. (a): Neither systemic nor RV mtDNA levels differ between CEH and ObAAEH, but levels of COX3 and ND1 were lower in the RV vs. IVC of CEH patients. (b) COX3 and ND1 gradient across the kidney was higher in ObAAEH compared to CEH. ^†P ≤ 0.05 vs. CEH, ^‡P ≤ 0.05 vs. systemic. Abbreviations: CEH, Caucasian essential hypertensive; HV, healthy volunteers; mtDNA, mitochondrial DNA; IVC, inferior vena cava; ObAAEH, Obese African American essential hypertensive; RV, renal vein.
