The symporter YhcL and two ATP binding cassette transporters, YtmJKLMN and YckKJI, were shown to mediate L-cystine uptake in Bacillus subtilis. A triple DeltayhcL DeltaytmJKLMN DeltayckK mutant was unable to grow in the presence of L-cystine and to take up

The role of selenium as potential cancer chemopreventive and chemotherapeutic agents has been supported by epidemiological, preclinical and clinical studies. Although cell apoptosis has been evidenced as a critical mechanism mediating the anticancer activity of selenium, the underlying molecular mechanisms

The simultaneous speciation of elements is of great concern, especially in the study of the interactions of species in living organisms. Here we report a method based on the coupling of HPLC-ICP-MS that is capable of separating and analyzing different

Copper and iron are two widely studied transition metals associated with hydroxyl radical (˙OH) generation, oxidative damage, and disease development. Because antioxidants ameliorate metal-mediated DNA damage, DNA gel electrophoresis assays were used to quantify the ability of ten selenium-containing compounds

Selenium-containing compounds play an important role in antioxidant defense systems, binding to toxic metals, preventing their uptake into cells, and thus protecting cells from metal-induced formation of reactive oxygen species. Here, we present a proposal for a relatively new method
