Figure 2. Dose-response for APAP toxicity in HepaRG cells.
Confluent cells were treated with various concentrations of APAP and GSH, APAP-protein adducts, JC-1 fluorescence, and LDH release were measured before and 24h after APAP treatment (0–20 mM) as described in the methods section. (A) Cellular glutathione content (B) APAP-protein adducts (C) Ratio of red to green fluorescence of the JC-1 assay (D) Percentage of total LDH activity found in culture medium. Data are expressed as mean ± SE of 3–4 independent cell preparations. *P<0.05 (compared to controls)
