Bioinformatics Analysis and Identification of Key Candidate Genes Associated with Nephrotoxicity Induced by Cobalt

Cobalt(Co)is a silver-gray,high-intensity,widely distributed metal element that exists in cobalt compounds,and its common valences are bivalence(Co2+)and trivalence(Co3+)[1].The main routes of Co-exposure are occupational and environmental exposures.The human body can be exposed to high concentrations of Co2+through inhalation of contaminated air,consumption of contaminated food and water,or ingestion of Co-containing supplements[2].
