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 selenium salt selenite (SeO(3)(2-)) is cytotoxic in low to moderate concentrations, with a remarkable specificity for cancer cells resistant to conventional chemotherapy. Our data show that selenium uptake and accumulation, rather than intracellular events, are crucial to the specific

Selenocystine (CysSeSeCys), a diselenide aminoacid exhibiting glutathione peroxidase-like activity and selective antitumor effects, was examined for in vivo antigenotoxic and antioxidant activity in Swiss albino mice after exposure to a sublethal dose (5 Gy) of γ-radiation. For this, CysSeSeCys was administered

Epidemiological and clinical studies have demonstrated that dietary supplementation of selenium (Se) could reduce the incidence of human cancers. In this study, selenocystine, a nutritionally available selenoamino acid, was identified as a novel agent with broad-spectrum antitumor activity. A panel
