Potent iron chelators increase the mRNA levels of the universal cyclin-dependent kinase inhibitor p21(CIP1/WAF1), but paradoxically inhibit its translation: a potential mechanism of cell cycle dysregulation.

'Iron (Fe) chelators are potential antitumor agents. Cellular Fe depletion results in a G1/S arrest but the precise molecular mechanisms involved remain unclear. Recent studies have shown that this process is complex with multiple cell cycle molecules being involved. We previously showed that Fe chelators such as 2-hydroxy-1-naphthylaldehyde isonicotinoyl hydrazone ... More
