  1. a Values shown for lead, arsenate and H2O2 represent the transcript copy number ng-1 total RNA in each experimental condition relative to transcript levels in 0.2X NB and the SE (parentheses, n = 6 qRT-PCR reactions per treatment). The relative expression of each gene in 5 mM Cr(VI) is shown for comparison.
  2. b 0.5 and 50 μM lead also tested with similar results
  3. c 0.5 and 50 mM Arsenate and H2O2 also tested with similar results
