Spermidine together with putrescine and spermine compose a family of biogenic polyamines (polycations) that are required for the survival of the vast majority of living cells. Polyamines interact with negatively charged molecules such as proteoglycan, glycated proteins and nucleic acids (DNA and RNA). Biogenic polyamines are found to modulate protein synthesis at different levels. This effect may be explained by the ability of polyamines to bind and influence the secondary structure of tRNA, mRNA, and rRNA. Spermine also helps stabilize nucleic acid helical structure and the conformation of glycated proteins such as the histones. Spermine and spermidine are components of various nucleic acid transfection protocols. Spermidine Inhibits neuronal nitric oxide synthase (nNOS). Binds and precipitates DNA; may be used for purification of DNA binding proteins. Stimulates T4 polynucleotide kinase activity.
Spermidine is biogenic polyamine formed from putrescine, a precursor of spermine. It was first detected in human sperm, but occurs widely in nature. It is essential in both normal and neoplastic tissue growth. Spermidine has a role in cell growth processes and the formation and interconversion of spermidine in mammalian cells has been reported. It has been studied in the regulation of tRNA methyltransferase activity and stimulates T4 polynucleotide kinase activity.

Epithelial-to-mesenchymal transition (EMT) is involved in embryonic development as well as in several pathological conditions. Literature indicates that polyamine availability may affect transcription of c-myc, matrix metalloproteinase (MMP)1, MMP2, TGFbeta(1), and collagen type I mRNA. The aim of this study

Although autophagy has widely been conceived as a self-destructive mechanism that causes cell death, accumulating evidence suggests that autophagy usually mediates cytoprotection, thereby avoiding the apoptotic or necrotic demise of stressed cells. Recent evidence produced by our groups demonstrates that

Age-dependent memory impairment is known to occur in several organisms, including Drosophila, mouse and human. However, the fundamental cellular mechanisms that underlie these impairments are still poorly understood, effectively hampering the development of pharmacological strategies to treat the condition.

The biochemistry and biological function of the naturally occurring polyamines, putrescine, spermidine, and spermine, have been reviewed with special reference to animal organisms. These compounds are universally distributed in all living material. Their biosynthesis from ornithine and methionine is accurately
