Article Synopsis
- Selenium can have a protective role against cancer at low concentrations but a direct tumor-fighting effect at higher doses, though the exact mechanisms are not fully understood.
- In experiments, a concentration of 20 micromol/l of Na(2)SeO(3) significantly inhibited the growth of NB4 cells and induced changes suggesting cell death, while a lower concentration of 2 micromol/l had no such effects.
- Gene expression analysis revealed that different concentrations of selenium lead to distinct changes in gene regulation, highlighting the complexity of its anticancer mechanisms and suggesting potential pathways for leukemia treatment.
Native liver ferritin of Dasyatis akajei (DALF), apoDALF, and reconstituted DALF were employed to construct a ferritin reactor, respectively. An apparatus consisting of a mixer, a ferritin reactor, and a magnetic stirrer was constructed to study capacity and feasibility of trapping Cu2+ in the flowing seawater. The experimental results showed that the numbers of trapping Cu2+ with DALF reactor were higher than these with the reactors of apoDALF and reconstituted DALF, respectively, giving the maximal numbers of 98 +/- 5 Cu2+ per molecular DALF in 120 h.

The molecular weight of the liver ferritin of D. akajei (DALF) was measured to be 400 kDa by PAGE.
