abstract = "Adverse effects of non-occupational exposure to cadmium (Cd) are increasingly
acknowledged. Using a rat model of oral Cd exposure in drinking water we have shown
that skin is a target for this metal. Due to contribution of individual variability to the
intensity of cadmium toxicity, dermatotoxicity of two environmentally relevant Cd
doses (5 and 50 ppm) was examined in individuals of two rat strains, Albino Oxford
(AO) and Dark Agouti (DA), which differ in response to chemicals. A dose-dependent
accumulation of Cd in the skin/epidermal cells was noted in both strains, and although
there were no strain differences in the Cd accumulation, the degree of skin response to
the metal differed. Signs of skin damage were evident in both strains, but response to
injury was more pronounced in DA. Individuals of DA rats responded by an increase
in the levels of antioxidant defense enzymes in the skin already at lower dose, in
contrast to AO (which reacted to higher dose solely), implying higher sensitivity of DA
strain to Cd-induced toxicity. Epidermal cells from both strains developed stress
response, however increased GSH, and higher metallothionein/MT-1 and MT-2
mRNA, Nrf2 protein, apoptosis, Ahr and Cyp genes in AO, depicting this strain`s
ability to better defend against Cd insult. Epidermal cells` IL-1β, TNF and IL-6
response was induced by Cd in DA, while pro-inflammatory cytokine production was
unchanged in AO (though increased following stimulation with S. epidermidis), with
increased IL-10 as a possible underlying mechanism. T cells from non-exposed rats
produce more IFN-γ and IL-17 in co-culture with epidermal cell from Cd–exposed DA
rats what strengthens the view that this strain is more prone to metal’s dermatotoxicity.
These data give a new insight into repercussion of genetic variability to toxicity of
cadmium acquired by the skin via gut, bearing relevance for variations in the link
between dietary cadmium and inflammation-based skin pathologies.",
