Results of the WST-1 assay after 24 h exposure of HuH-7 cells to APAP (A), CeO2 NPs (B) and both in combination (C) at different concentrations ± standard deviation normalized to negative control (Dulbecco’s modified Eagle medium, DMEM) and positive control (TritonX). Red line indicates the EC50 (effective concentration where viability is reduced to 50%). All tests with at least three biological and six technical replicates. p ≤ 0.05 = *, 0.01 = **, 0.001 = ***.
