Purine nucleoside phosphorylase dominates Influenza A virus replication and host hyperinflammation through purine salvage [PDF]

Signal Transduction and Targeted Therapy
Influenza A virus (IAV) poses a significant threat to human health. The outcome of IAV results from the viral-host interaction, with the underlying molecular mechanisms largely unknown.

Evaluating antitumor activity of Escherichia coli purine nucleoside phosphorylase against head and neck patient‐derived xenografts [PDF]

Cancer Reports, 2023
Background Purine nucleoside phosphorylase (PNP) gene transfer represents a promising approach to treatment of head and neck malignancies. We tested recombinant adenovirus already in phase I/II clinical testing and leading‐edge patient‐derived xenografts

The Characterization of the Purine Nucleoside Phosphorylase from Agaricus bisporus and Its Potential Application in Reducing Purine Content in Beer [PDF]

Journal of Fungi
Beer, the most popular alcoholic beverage, poses health risks for individuals with gout and hyperuricemia due to its high purine content. Herein, we identified a novel purine nucleoside phosphorylase (AbPNP) from the edible mushroom Agaricus bisporus and
