Cover Story: Polyamines, spermidine, and spermine are positively charged aliphatic cations. They are critical in the regulation of molecular interactions and biological functions. Because of their important physiological role, their cellular levels are tightly regulated through their import, export, de novo synthesis, and catabolism. Enzymes and enzymatic cascades involved in polyamine metabolism are well characterized. Disturbances in the activity of enzymes involved in polyamine metabolism and the consequent changes in polyamine levels and products of their metabolism lead to cell injury and tissue damage. The preponderance of scientific evidence substantiates the critical role of polyamines and their metabolism in the maintenance of physiological normalcy and the disturbances in polyamine levels and catabolism in the mediation of tissue injury.
