Relative mRNA expression levels of drug transporters exhibiting age differences in human kidney tissue. The 30 transporter mRNA expressions for human kidney tissue were graphed to illustrated age (age group: below 50 years old (<50 years) and age group: 50 years and older (≥50 years)) differences. The bars represent the mean relative mRNA expression; the error bars indicate the standard error mean from n > 3 samples. Statistical analysis was performed using multiple Student’s t-test (Sidak-Bonferroni correction method (alpha = 5%)).
