Impact of 10 μM rifampicin (white bars) or rifabutin (gray bars) for 24 h, 96 h, or 144 h on mRNA expression of total NR1I2 or its splice variants in LS180 cells, normalized to solvent control (black bars). Data shown is the mean ± S.D. of four independent biological replicates. Statistical significance was evaluated by non-parametric Kruskal-Wallis test and Dunn’s test, correcting for multiple comparisons
