Previous research has shown the isolated perfused porcine skin flap (IPPSF) to be a novel in vitro experimental model for investigating xenobiotic percutaneous absorption. In this study, the IPPSF was used to biochemically and morphologically assess the dermatotoxicity of 2-chloroethyl

Vinthionine (S-vinyl-DL-homocysteine) is hepatocarcinogenic in rats and mice. [Vinyl-14C]vinthionine binds covalently to rat liver DNA, RNA and protein in vivo, but not in vitro. This amino acid is directly mutagenic in Salmonella typhimurium TA100 and TA1535; the mechanism of its

The elongation factor 1A proteins (eEF1A1/A2) are known to play a role in tumours. We previously found that a more basic isoform of eEF1A (MBI-eEF1A) is present in the cytoskeletal/nuclear-enriched extracts of CCRF-CEM T-lymphoblasts but not in those of normal

In a previous study, we found that ethane dimethanesulphonate (EDS) compromised the fertilizing ability of proximal cauda epididymal sperm from the rat within 4 days of exposure, an effect that persisted in castrated, testosterone (T)-implanted animals, establishing direct action on

Sulfur mustard (bis-(2-chloroethyl)sulfide) is a well-known chemical warfare agent that induces debilitating cutaneous toxicity in exposed individuals. It is also known to be carcinogenic and mutagenic because of its ability to damage DNA via electrophilic attack. We previously showed that
