Preliminary Screening on Drugs with

DILI Potential in Four Liver Cell Lines

Methods: Sixteen drugs were employed as positive controls corresponding with the

livertox and four drugs without any reports or clinical observations associated with DILI

were utilized as negative control drugs. the CCK-8 assay was conduct in evaluating every

liver cell line in discriminating DILI in vitro.

Conclusion: HepaRG cell line was superior to other cell lines in

discriminating drugs associated with DILI potential. The abilities to predict

drugs associated with DILI were HepaRG > L-02 > hiHeps > HepG2

Applications of High-Content Screening

Assay in Four Liver Cell Lines

Method: A HCS assay was conducted based on five parameters (oxidative

stress, mitochondrial damage, endoplasmic reticulum stress, disorders of

neutral lipid metabolism and calcium homeostasis).

Note: Representative high content images from the HepaRG cell

line treated with diclofenac sodium, buspirone hydrochloride and

danazol, respectively.

Conclusion: The HepaRG cell line was more sensitive to DILI screening in vitro

compared to other cell lines and was considered as a superior cell line model in

multi-parametric screening assay.

Method: Eleven traditional liver-related biomarkers (ALT, AST, ALP, γ-GT,

LDH, TBIL, DBIL, TBA, CHE, 5’-NT and MAO) with two new biomarkers

(GLDH and MDH) recommended by the Predictive Safety Testing Consortium

(PSTC) were inspected in the four cell lines to predict drugs with DILI potential

Conclusion: MDH showed a putative potential for predicting DILI in vitro

identical to the traditional biomarkers AST and LDH.
