Comparing intracellular stability and targeting of sulfobetaine quantum dots with other surface chemistries in live cells
(2012)The in vivo labeling of intracellular components with quantum dots (QDs) is very limited because of QD aggregation in the cell cytoplasm and/or QD confinement into lysosomal compartments. In order to improve intracellular ...

Detection of the His-heme Fe2+-NO species in the reduction of NO to N2O by ba3-oxidase from thermus thermophilus
(2005)Reaction pathways in the enzymatic formation and cleavage of the N-N and N-O bonds, respectively, are difficult to verify without the structure of the intermediates, but we now have such information on the heme a3 2+-NO ...

Evidence that a metabolilte of equine estrogens, 4-hydroxyequilenin, induces cellular transformation in vitro
(2001)Estrogen replacement therapy has been correlated with an increased risk of developing hormone-dependent cancers. 4-Hydroxyequilenin (4-OHEN) is a catechol metabolite of equilenin and equilin which are components of the ...

Induction of caspase-independent programmed cell death by vitamin E natural homologs and synthetic derivatives.
(2009)Current observations in the literature suggest that vitamin E may be a suitable candidate for cancer chemotherapy. To investigate this further, we examined the ability of the vitamin E natural homologs [alpha-, beta-, ...

The phosphoform of the regulatory subunit RII of cyclic AMP-dependent protein kinase possesses intrinsic topoisomerase activity
(1985)The phosphoform of the type II regulatory subunit (phospho-RII-cAMP) of cAMP-dependent protein kinase from rat liver was found to possess intrinsic topoisomerase activity towards several DNA substrates such as φX174, pBR322, ...
