UArizona Pharmacology and Toxicology professor and BIO5 faculty Dr. Donna Zhang, leads her lab to examine how chronic exposure to arsenic causes genetic changes linked to disease development. By using QIAGEN Genomic Services, the team discovered that arsenic and high-fat diets induce similar transcriptomic changes. Through this analysis, the team also found that when a set of master regulator RNA molecules had been inactivated, there were fewer arsenic-induced dietary changes.
