March 2008 in “AJP Endocrinology and Metabolism” Spermidine/spermine-N(1)-acetyltransferase (SSAT) was identified as a crucial enzyme regulating cellular polyamine content, impacting normal and neoplastic growth, ion channel regulation, and potentially cancer chemotherapy. SSAT activity was highly regulated and could be induced by various stimuli, affecting polyamine homeostasis and linking polyamine metabolism to lipid and carbohydrate metabolism. Increased SSAT activity led to a futile cycle consuming ATP and acetyl-CoA, and was associated with adverse effects such as pancreatic cell death, tissue growth blockage, behavioral changes, and hair loss. SSAT also interacted with proteins like hypoxia-inducible factor-1 alpha and NF-kappaB, though the exact mechanisms were unclear. While SSAT was considered a potential target for diseases beyond cancer, its broad physiological effects necessitated careful targeting to avoid toxicity.
