Cover Story: Complex molecular interactions drive biological processes in response to environmental exposures. Understanding antagonistic interactions is important because pathologic outcomes can result from adverse responses or failure of beneficial mechanisms. Environmental metal manganese is beneficial at low doses but a neurotoxicant at high doses and is suitable for the study of antagonistic interactions. Utilizing an advanced multi-omics approach, we show that metabolite and transcript changes can be combined with cellular and mitochondrial specific responses to provide a systems view of underlying neurotoxic mechanisms. Our results show that antagonistic interactions reflect mechanisms of mitochondrial oxidative stress, cellular thiol oxidation and protective effects of mitochondrial bioenergetics. View this paper
