... are induced in BJAB cells following the initiation of apoptosis, but KIPase activity remains constant. In order to ascertain whether KIPase behaves in a proliferation dependent manner in cells ... described for the human B-lymphoma cell line BJAB [1]. In this case, inhibition of KIPase activity using a cell-permeable inhibitor resulted in an increase in p27 KIP1 abun...

... that cells expressing wild-type HFE displayed a striking decrease in cell-surface bind- ing of transferrin, and that little or no reduction in transferrin binding was observed in cells expressing ... other genes involved in iron metabolism. This includes hepci- din, a 25 amino acid antimicrobial peptide that is expressed in liver cells and is now recognized as a key regula...

... be used as a substrate for testing AUH activity in a routine setting. Indeed, we were able to show that AUH activity in fibro- blasts can be determined by monitoring the forma- tion of 3-hydroxyglutaryl-CoA. ... hydratase activity is associated with mutations in the AUH gene. This indi- cated that AUH, in addition to its RNA binding func- tion, must play an important role in...

... This suggests that the chelators may also be acting intracellularly, inhibiting Fe incorporation into ferritin. In comparison, the proportion of 59 Fe in ferritin did not change significantly in ... cells and used in Fe-dependent reactions essential for growth and proliferation, is uncertain. Hence, it is of interest to investigate the uptake and metabolism of NTBI in normal...

Prelabeling of ATP depleted cells with UIC2 completely abolished the subsequent binding ... MM12.10, in accordance with the enhanced binding of the first mAb. Vanadate and beryllium fluoride, but not fluoro-aluminate, reversed the effect of cyclosporin A, preventing UIC2 binding and...
