Spermine Enhances the Peroxidase Activities of Multimeric Antiparallel G-quadruplex DNAzymes

Biosensors
G-quadruplex (G4) DNAzymes with peroxidase activities hold potential for applications in biosensing. While these nanozymes are easy to assemble, they are not as efficient as natural peroxidase enzymes.

Alterations of renal polyamine metabolism in mice with folic acid-induced chronic kidney disease

Biochemistry and Biophysics Reports
Chronic kidney disease (CKD) often follows acute kidney injury, leading to renal fibrosis and progressive renal failure. Spermine, a polyamine with antioxidant and anti-inflammatory properties, helps reduce renal fibrosis and may serve as a biomarker for

New routes for spermine biosynthesis

Journal of Biological Chemistry
The polyamine spermine (Spm) is a flexible linear teraamine found in bacteria and eukaryotes and in all known cases is synthesized from triamine spermidine by addition of an aminopropyl group acquired from decarboxylated S-adenosylmethionine (dcAdoMet).

Insights from Metabolomic and Transcriptomic Analyses into Sulforaphane’s Protective Mechanism Against Deoxynivalenol Toxicity via Spermine Regulation

Toxins
Deoxynivalenol (DON) is a mycotoxin ubiquitously present in the environment. Emerging evidence demonstrated that sulforaphane (SFN) exerts potent protective effects against DON-triggered cytotoxicity through multimodal mechanisms.
