Molecular Mechanisms of Metal Toxicity and Carcinogenesis, 2001 Developments in Molecular and Cellular Biochemistry Series, Vol. 34

During the last two decades, chemical and cellular studies have contributed enormously to our understanding of metal-induced carcinogenesis, and many hypotheses on the role of metals in pathophysiological processes have been investigated. In addition, new techniques are available to shed light on the mechanism of carcinogenesis in molecular terms. This conference on Molecular Mechanisms of Metal Toxicity and Carcinogenesis in September 2000 focused on the latest research in molecular mechanisms of metal-induced toxicity and carcinogenesis. The conference promoted a multidisciplinary investigative approach and included presentations from international experts on state-of-the-art information in this field.
