Impact of quantum dots (QDs) on metals homeostasis in keratinocyte. Quantitative reverse transcription PCR (RT-qPCR) assay analysis of the mRNA expression of genes encoding proteins involved in metal homeostasis (A) with a focus on Zn homeostasis (B). Human primary keratinocytes were exposed for 24 h to 25 nM of pristine QDs, 6.25 nM of aged QDs, or 50 μM of In(III)-acetate or Zn(III)-acetate. Data are mean ± standard deviation of three independent experiment performed on human primary keratinocytes from the same donor, with two technical replicates. Statistical significance: p ≤ 0.05, *exposed vs. control.
