    Evaluation of drug carrier hepatotoxicity using primary cell culture models
    (Elsevier, 2023) Kibar, Gunes; Dutta, Subhadeep; Rege, Kaushal; Usta, O. Berk
    This study aims to establish a primary rat hepatocyte culture model to evaluate dose-dependent hepatotoxic effects of drug carriers (lipopolymer nanoparticles; LPNs) temporal. Primary rat hepatocyte cell cultures were used to determine half-maximal Inhibition Concen-trations (IC50) of the drug-carrier library. Drug-carrier library, at concentrations <50 mu g/mL, is benign to primary rat hepatocytes as determined using albumin and urea secretions. Albumin, as a hepatic biomarker, exhibited a more sensitive and faster outcome, compared to urea, for the determination of the IC50 value of LPNs. Temporal measurements of hepatic biomarkers including urea and albumin, and rigorous physi-cochemical (hydrodynamic diameter, surface charge, etc.) characterization, should be combined to evaluate the hepatotoxicity of drug carrier libraries in screens.(c) 2023 Published by Elsevier Inc.
