Quinocetone, a new quinoxaline 1,4-dioxide derivative, has been approved as an animal growth promoter in China since 2003. To investigate the genotoxicity of quinocetone in vitro, its effects on the extent of DNA injury in human hepatoma (HepG2) cells accompanied by chromosomal damage and genomic DNA alterations were tested. The cell viability test(More)
We investigated mitogen-activated protein kinase (MAPK) pathways as well as reactive oxygen species (ROS) in olaquindox-induced apoptosis. Exposure of HepG2 cells to olaquindox resulted in the phosphorylation of p38 MAPK and c-Jun N-terminal kinases (JNK). To confirm the role of p38 MAPK and JNK, HepG2 cells were pretreated with MAPKs-specific inhibitors(More)
Olaquindox, a synthetic antimicrobial compound, was banned as feed additives in the U.S. and the EU. In China, the use of olaquindox is banned in poultry and aquaculture feed, restricted in livestock feed for growth promotion. Olaquindox’s safety is the object of increasing attention. The present study was undertaken to investigate whether and how(More)
