Figure 1 Incidence of acute kidney injury (AKI) following cardiac surgery grouped according to lanosterol synthase (LSS) rs2254524 genotype. At any stage, the incidence of AKI increases with the number of LSS A alleles (χ2=13.68; P=0.001). Abbreviation: pts, patients.

Figure 2 Endogenous ouabain (EO) concentrations in human kidney samples grouped according to lanosterol synthase (LSS) rs2254524 genotype. The EO concentration in both cortex (red column) and medulla (blue column) is higher in tissues from patients with the LSS rs2254524 AA versus CC genotype. Data are expressed as nanogram of EO per gram of renal tissue (mean ± standard error of the mean).

Figure 3 Blood pressure (BP) during the follow-up period in the hypertensive cohort. No significant differences in systolic (SBP) and diastolic BP (DBP) values were found among the lanosterol synthase (LSS) genotype groups. The mean number of antihypertensive therapies used to maintain BP in the target range (<140/90mmHg) is reported. Data are expressed as mm Hg (mean values).
