Cover Story: Polyamines are present in all organisms and are essential for mammalian cell growth and survival, and for development. Several studies have shown both beneficial and detrimental effects of polyamines on human health. Polyamine levels are normally maintained within narrow physiological ranges, and an altered polyamine metabolism is sufficient to provoke various pathologies, including cancer, neurological defects, and aging. While supplementation with the polyamine spermidine can delay aging via the activation of autophagy, increased polyamines can also promote progression of different cancer types by driving cell proliferation. Accordingly, a detailed understanding of mechanisms that control polyamine homeostasis in human health and disease is needed to develop safe and effective strategies for polyamine-targeted therapy.
