Development of Amine-Oxidase-Based Biosensors for Spermine and Spermidine Analysis

, 2017
In this work a detailed description of the development of amine oxidase-based electrochemical biosensors for the selective determination of the biogenic amines is presented. The enzymes required for this operation are Polyamine Oxidase (PAO) and Spermine Oxidase (SMO) which are physically entrapped in poly(vinyl alcohol) bearing styrylpyridinium groups

Effect of Nitric Oxide Fumigation Combined with Hypobaric Treatment on the Postharvest Quality and Metabolism of Polyamines and Glutathione in Xiaobai Apricots [PDF]

Shipin Kexue
To investigate the regulatory effect of nitric oxide (NO) fumigation combined with hypobaric treatment (HYT) on the postharvest quality of Xiaobai apricots, ‘Luntai’ apricots were treated with exogenous NO under hypobaric conditions (HYT + NO).

Mitochondrial alterations induced by serum amine oxidase and spermine on human multidrug resistant tumor cells

, 2004
Multidrug resistance (MDR) has been studied extensively because it is one of major problems in cancer chemotherapy. The MDR phenotype is often due to overexpression of P-glycoprotein (P-gp), that acting as an energy-dependent drug efflux pump exports ...

Pear PbrPAO14 modulates pollen tube growth in vitro via altering tip-localized H₂O₂ content

Scientia Horticulturae
Polyamine oxidase (PAO)-derived hydrogen peroxide (H2O2) is known to participate in various plant growth and developmental processes. However, its role in pollen tube growth (PTG) of fruit trees remain elusive.

Effects of putrescine, cadaverine, spermine, spermidine and β-phenylethylamine on cultured bovine mammary epithelial cells

Italian Journal of Animal Science, 2010
A bovine mammary epithelial cell line (BME-UV1) and three-dimensional collagen primary bovine organoids were used to evaluate the effects of cadaverine, putrescine, spermine, spermidine and β-phenylethylamine on mammary epithelial cells.

The involvement of arbuscular mycorrhizal fungi in modulating polyamine metabolism and low-temperature tolerance enhancement in white clover

Frontiers in Plant Science
Sustained low temperatures can prevent white clover (Trifolium repens L.) from overwintering and regreening, making it difficult to revive the plants in the spring.
