ABSTRACT
Binaprofen (C18H23NO5) is a drug not commercially available that causes liver injury; however, the underlying mechanism is unknown. The aim of the present study was to determine the mechanism underlying binaprofeninduced liver injury at the genetic level. Zebrafish were treated with binaprofen. Serum biomarkers [alanine transaminase (ALT), aspartate transaminase (AST) and lactate dehydrogenase (LDH)], malondialdehyde (MDA) and glutathione (GSH) content analysis, liver cell morphology examination, DAPI staining, electron microscopy, microarray analysis and reverse transcriptionquantitative (RTq)PCR were performed 12, 24 and 48 h posttreatment to analyze the mechanism underlying binaprofeninduced liver injury. Following exposure to binaprofen, zebrafish serum levels of ALT, AST and LDH increased; MDA content of liver tissue increased and GSH content decreased. Liver cells exhibited mild to moderate vacuolization and mitochondria exhibited vacuolization and disrupted cristae. Liver cell apoptosis rate increased. There were 190 common differentially expressed genes at 12, 24 and 48 h. Gene Ontology analysis showed that the function of downregulated genes was primarily associated with 'DNA replication', 'DNA metabolic process', 'cell cycle', 'cell redox homeostasis', 'mitochondrion' and 'lipid transport'. The function of upregulated genes was primarily associated with 'peroxisome proliferator', 'oxidation activity', 'peroxisome' and 'apoptosis'. Pathway analysis showed that downregulated genes were those pertaining to 'cell cycle', 'DNA replication', 'ribosome', 'spliceosome', 'pyrimidine metabolism', 'purine metabolism', upregulated genes were those pertaining to 'PPAR signaling pathway', 'p53 signaling pathway'; RTqPCR assay supported the microarray results. The mechanism underlying binaprofeninduced liver injury was associated with lipid peroxidation and apoptosis. Binaprofen downregulated genes associated with lipid transport and antiapoptosis genes, upregulated proapoptosis genes and induces liver cell injury via the mitochondrial signaling pathway.
