Aaron Barchowsky - Research

The primary focus of current research is investigating the cellular and molecular mechanisms underlying human blood vessel and lung diseases caused by environmental exposures to metals and chronic changes in redox status.   In vivo and cell cultured based studies focus on the molecular pathology and etiology of vascular disease caused by chronic exposure to low levels of arsenic in drinking water.  The cell signaling pathways that mediate arsenic stimulated pathogenic phenotypic changes in endothelial cells are being investigated.  Additional studies examine the molecular signaling mechanisms mediating gene induction and silencing in airway epithelial cells exposed to chromium.  The objective of these studies is to identify the pathways through which inhaled chromium aggravates lung injury from infections and exposure to other metals.
