Functional Characterization of the P‐Type ATPases ATP13A3 and ATP13A4 as Plasma Membrane Polyamine Transporters [PDF]

FASEB J
ATP13A3 and ATP13A4 mediate the plasma membrane uptake of the polyamines, putrescine and spermidine, in an ATP‐dependent manner. ATP13A3 is broadly expressed across human tissues, whereas ATP13A4 is expressed at relatively high levels in the brain and lung.

Alarmone ppGpp modulates bacterial motility, zeamine production, and virulence of Dickeya oryzae through the regulation of and cooperation with the putrescine signaling mechanism

mSphere
Putrescine is an important interspecies and interkingdom communication signal, modulating the bacterial motility, biofilm formation, and virulence of D. oryzae. The understanding of the regulation of putrescine biosynthesis and transport in D.

EVALUATION OF THE EFFECT OF EXOGENOUS PUTRESCINE DURING THE MATURATION AND GERMINATION in vitro OF SOMATIC EMBRYOS IN TWO AGAVE GENOTYPES

Tropical and Subtropical Agroecosystems, 2023
Background. Agaves are an important economic source in industrial products, in the food and pharmaceutical industry, steroidal animal feed, ornamental plants and as a material for biofuels. Despite their economic importance, some species present problems

Transcriptome Profile of Fusarium graminearum Treated by Putrescine

Journal of Fungi, 2022
Fusarium graminearum (F. graminearum) is the main pathogen of Fusarium head blight (FHB) in wheat, barley, and corn. Deoxynivalenol (DON), produced by F. graminearum, is the most prevalent toxin associated with FHB.

Putrescine Upregulates Melanogenesis Through Modulation of MITF Transcription Factor in B16F1 Mouse Melanoma Cells

Food Technology and Biotechnology
Research background. Ageing is a biochemical, metabolic and genetic physiological phenomenon. The suppression of melanin biosynthesis, evident in the greying of the hair, is a hallmark of ageing resulting from translation failure, reduced enzyme activity

Effect of Putrescine Treatment on Chilling Injury, Fatty Acid Composition and Antioxidant System in Kiwifruit. [PDF]

PLoS ONE, 2016
We investigated the effects of different concentrations (0, 1, 2 and 4 mM) of putrescine on chilling injury, fruit quality, ethylene production rate, fatty acid composition and the antioxidant system of cold-stored kiwifruit (Actinidia chinensis Planch ...

Innate Immunocompetent hiPSC‐Derived Neurospheroids Capture Early CNS Responses to rAAV

Advanced Science, EarlyView.
Knowledge of human CNS immune responses to AAV‐based gene therapies remains limited due to the lack of immune‐competent human models. Here, a hiPSC‐derived 3D neuroimmune platform integrating neurospheroids and microglia is established using stirred‐tank bioreactors.

Spectrofluorometric Determination of Putrescine: Optimization of the Putrescine–Orthophthaldehyde Complex Using Spectrofluorometry

Journal of AOAC INTERNATIONAL, 2016
Abstract In alkaline medium, the complex formed between putrescine and orthophthalaldehyde was studied using spectrofluorescence. The derivative is kinetically stable 24 h after complexation. The stoichiometry of the complex is 1:1 at maximum fluorescence intensity, also 24 h after complexation.
