Relative gene expression
of XMEs in human tissue organoids after
AAI treatment. RT-qPCR and the 2–ΔΔCT method were used to determine CYP1A1, CYP1A2, and NQO1 expression in gastric (D95 and D88; A,
C, and E) and kidney (D50 and D21; B, D, and F) organoids treated
with the indicated AAI concentrations for 48 h. Values were normalized
to mRNA expression of the housekeeping gene GAPDH and are relative to the vehicle control (0.1–1% water). Results
are shown as mean ± SD (n ≥ 3). Statistical
analysis was performed by log2 transforming the data and a one-sample t-test with Bonferroni correction against the control mean
of 0 (*p < 0.05; **p < 0.01).
