A perspective of polyamine metabolism.
Polyamines are essential for the growth and function of normal cells. They interact with various macromolecules, both electrostatically and covalently and, as a consequence, have a variety of… Expand

The polyamine transport system as a target for anticancer drug development
The vast majority of anticancer drugs in clinical use are limited by systemic host toxicity due to their non-specific side effects. These shortcomings have led to the development of tumour specific… Expand

Influence of metallothionein-1 localization on its function.
Metallothioneins (MTs) have a major role to play in metal metabolism, and may also protect DNA against oxidative damage. MT protein has been found localized in the nucleus during S-phase. The mRNA… Expand

Alterations in polyamine catabolic enzymes in human breast cancer tissue.
High concentrations of acetyl polyamines have been observed in human breast cancer compared with the equivalent normal tissue, however, no explanation as to the reason for the increases has been… Expand

Mechanisms of spermine toxicity in baby-hamster kidney (BHK) cells. The role of amine oxidases and oxidative stress.
Spermine was toxic to BHK-21/C13 cells in the absence of any extracellular metabolism of the amine. Inhibition of copper-containing amine oxidases with aminoguanidine partially prevented the… Expand

Induction of spermidine/spermine N1-acetyltransferase in human cancer cells in response to increased production of reactive oxygen species.
Reactive oxygen species (ROS) are involved in a number of disease states where they are believed to be responsible for cellular damage. In this study we examined the effect of ROS generation on… Expand

Insufficiently charged isosteric analogue of spermine: interaction with polyamine uptake, and effect on Caco-2 cell growth.
We characterised a novel, charge-insufficient isosteric analogue of spermine, 11-[(amino)oxy]-4,9-diaza-1-aminoundecane (AOSPM). This analogue was synthesised by displacing aminopropyl group by… Expand
