Global Gene Expression Responses to Cadmium Toxicity in Escherichia coli

Received 8 October 2004/ Accepted 19 January 2005

Genome-wide analysis of temporal gene expression profiles in Escherichia coli following exposure to cadmium revealed a shift to anaerobic metabolism and induction of several stress response systems. Disruption in the transcription of genes encoding ribosomal proteins and zinc-binding proteins may partially explain the molecular mechanisms of cadmium toxicity.
