Quantitative real-time PCR expression of genes encoding Zn transporters (MT-1, ZnT5 and ZIP2) (a) and of specific bone differentiation markers (b) in femur tissues of rat pups (PND21) from control females and pups from females exposed to cadmium (50 mg/L Cd as CdCl₂) and / or zinc (60 mg/L Zn as ZnCl₂) during gestation and lactation. Data represent expression levels with respect to control samples. a (p < 0.05): significant difference compared to the control group (C); b (p < 0.05): significant difference compared to the Cd group (Cd).
