Expression of genes related to metal metabolism in the freshwater fish Hyphessobrycon luetkenii living in a historically contaminated area associated with copper mining

The GE of the non-translocated groups evidenced that MT, MTF-1 and CTR1 have organ specific differences between both communities. Additionally the translocation allowed to identify organ specific changes associated with the activation/inactivation of protective mechanisms. These findings indicate that MTF-1, MT and CTR-1 GE play an important role in the tolerance of H. luetkenii to Cu contamination.
