Mitotane cytotoxicity and metabolism after CYP11B1 modulation in H295R cell line.

<p>(A) Mitotane cytotoxicity was not influenced by CYP11B1 interference (p = ns, comparing IC50 doses of CYP11B1 siRna cells and non-targeting siRna control cells). Three replicate wells for each experiment (n = 2) were used to determine each data point. (B) CYP11B1 modulation did not influence uptake of mitotane and its metabolization (p = ns, comparing drug levels of CYP11B1 siRna cells and non-targeting siRna control cells). Four independent experiments were used to determinate each data point, measured in HPLC-UV.</p

Effects of mitotane and 20 μM metyrapone on H295R cell viability.

<p>Three technical replicate wells for each experiment (n = 3) were used to determine each data point. P = ns comparing mitotane treatment vs. combined treatment with mitotane and metyrapone.</p

Effects of 25 μM mitotane and 20 μM metyrapone on cortisol levels.

<p>Four independent experiments were used to determine each data point. Metyrapone or mitotane treatment vs. untreated cells, P <0.05. Combined treatment with mitotane and metyrapone vs. untreated cells. P = 0.005.</p

Mitotane metabolites in ACC cells: Uptake, bioavailability and metabolization.

<p>Intracellular and extracellular concentration of mitotane and its metabolites in H295R, measured by means of HPLC–UV after metyrapone treatment. Six independent experiments were used to determinate each data point.</p

CYP11B1 expression after treatment with mitotane and metyrapone, or both.

<p>Data obtained from two independent experiments with two replicates for each experiment, and expressed as fold changes compared to β-actin expression (2-ΔΔCt). A > 2 fold increase was considered significant.</p

Efficiency of siRna transfection and silencing.

<p>(A) H295R cells transfected with a fluorescent siRna indicator. (B) CYP11B1 gene expression in CYP11B1 siRna cells and non-targeting siRna cells. Data obtained from two independent experiments with two replicates for each experiment. (C) Cortisol levels in CYP11B1 siRna cells and non-targeting siRna control cells. Four independent experiments were used to determine each data point.</p
