FIG. 3.

Effects of Cd on expression of markers of olfactory cellular injury. Fold-change in mRNA expression of the olfactory (A) mt1a, (B) hmox1, (C) omp, and (D) nrn1 following acute (48 h) and sub-chronic (16-day) Cd exposures and a depuration. Data represent the mean ± SEM of n = 8 individuals normalized to the expression of β-actin mRNA, and expressed as fold-change relative to control levels. Asterisks indicates statistically significant differences in gene expression relative to controls (*P <.05).
