Effect of treatment for three months with chemical carcinogen and non-carcinogens on liver miRNAome

ABSTRACT: Here, we examined the liver microRNA profile of male Fischer rats exposed through their diet to genotoxic (2-acetylaminofluorene) and epigenetic (phenobarbital, diethylhexylphthalate, methapyrilene HCL, monuron, and chlorendic acid) chemical hepatocarcinogens, as well as to non-hepatocarcinogenic treatments (benzophenone, and diethylthiourea) for three months. The aim of the study was to investigate how liver miRNA profiles relate to mode of action and carcinogenic potential of chemicals. In total miRNA profiles from 38 liver samples were examined. These included 3-5 samples for animal fed control diets or diet supplemented with designated chemicals. For each chemical a carcinogenic or a maximum tolerated dose was chosen based on published literature. The treatments were Diethylthiourea (
