Baseline levels of variables in wild type and cationic amino acid transporter-1 overexpressing mice in the 1-h periods immediately prior to stress tests.

Data are mean ± SEM (n = 5–7). * P ≤ 0.01 for obese compared with lean mice within the same genotype. P values were derived from un-paired t-tests. WT = wild type mice, CAT+ = endothelial CAT1 overexpressing mice, MAP = mean arterial pressure, HR = heart rate.
