abstract：:Dibenz[a,h]anthracene (DB[a,h]A) is a polycyclic aromatic hydrocarbon that is a by-product of combustion and a potent carcinogen. Few studies have investigated the effects of DB[a,h]A on mRNA and microRNA expression to dissect the mechanisms involved in carcinogenesis. In this study, mature male mice (Muta(™)Mouse) we...
