Polyamine metabolism changes in psoriasis

Indian Journal of Dermatology, 2013
Introduction: Polyamines - putrescine, spermidine and spermine are polycationic compounds ubiquitous for all living organisms. They are essential for the cell growth and differentiation, the control of cell cycle progress, apoptosis, and cancerogenesis ...

Oxidation of spermine by an amine oxidase from lentil seedlings

, 1991
Spermine is a substrate of lentil (Lens culinaris) seedling amine oxidase and the oxidation products are reversible inactivators of the enzyme. The spermine is oxidized at the terminal amino groups to a dialdehyde: 2 moles of hydrogen peroxide and 2 ...

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.

Voltage-dependent inhibition of outward Kir2.1 currents by extracellular spermine

, 2013
Outward currents through inward rectifier Kir2.1 channels play crucial roles in controlling the electrical properties of excitable cells. Extracellular monovalent and divalent cations have been shown to reduce outward K+ conductance. In the present study,

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
