Abstract
Introduction. Cadmium (Cd) is a common contaminant found in many foods, accumulates throughout life and, in high doses, is a significant health hazard for humans. Cadmium is of interest because its concentration in agricultural soils has become elevated over time; with dietary intake in Western countries often close to tolerable limits. Analysis of change in gene expression in response to environmental stressors could potentially aid in risk assessment and biomarker development for
human studies. Eisenia fetida are commonly used in ecotoxicological studies.
Object. To look at the impact of cadmium concentration on gene expression through comparative analysis of transcriptome data from E. fetida exposed to zero, low, medium and high doses of cadmium.
Methods. Artificial soil was spiked with three different Cd solutions [...]
