Glucose effect on ALA toxicity. The effect of Glucose was determined by exposing HEP G2 and HEP 3B cells to 0.5 mM ALA without (white) or with 2 mg/ml glucose (grey) for 24 h before the MTT assay was performed. Controls were grown with 2 mg/ml glucose alone (black). Viability was expressed in terms of population growth, as percent of an untreated control population with standard error of the mean (SEM).
