Evaluation of Polyamine Transport Inhibitors in a Drosophila Epithelial Model Suggests the Existence of Multiple Transport Systems [PDF]

Medical Sciences, 2017
Increased polyamine biosynthesis activity and an active polyamine transport system are characteristics of many cancer cell lines and polyamine depletion has been shown to be a viable anticancer strategy.

Combined inhibition of polyamine biosynthesis and uptake blocks Candida albicans virulence [PDF]

mBio
Polyamines, small organic polycations, are essential for life, and cells maintain polyamines via synthesis and uptake. Recently, we identified Hol1 as the high-affinity polyamine transporter in Saccharomyces cerevisiae.

Comprehensive analysis of the clinical and biological significances of polyamine metabolism in glioma [PDF]

Discover Oncology
Polyamines, including spermidine, spermine, and putrescine, are polycationic alkylamines in mammalian cells. However, the prognostic impact of polyamine in glioma remains unclear.

ATP13A4 Upregulation Drives the Elevated Polyamine Transport System in the Breast Cancer Cell Line MCF7

Biomolecules, 2023
Polyamine homeostasis is disturbed in several human diseases, including cancer, which is hallmarked by increased intracellular polyamine levels and an upregulated polyamine transport system (PTS).
