Nanodrugs mediate TAMs-related arginine metabolism interference to boost photodynamic immunotherapy.: This study explores the use of nanodrugs to interfere with arginine metabolism in tumor-associated macrophages (TAMs), enhancing the efficacy of photodynamic immunotherapy. L-Norvaline plays a crucial role in this metabolic interference (Chen et al., 2024).

In macrophages and many other cell types, L-arginine is used as a substrate by both nitric oxide synthase (NOS) and arginase to produce nitric oxide (NO) and urea, respectively. Because the availability of L-arginine is a major determinant for NO

Freezing represents a common conservation practice regarding vegetal foodstuffs. Since compositional features need to be monitored during storage, the development of rapid monitoring tools suitable for assessing nutritional characteristics arises as a pertinent issue. In this study, cowpea (Vigna unguiculata

The importance of magnesium (Mg) for plant growth is well-documented. Silicon (Si)-mediated alleviation of mineral deficiencies has been also reported in a number of plant species; however, there is no report on the relevance of Si nutrition in plants grown

Choline kinase catalyzes the initial reaction step of choline metabolism that produces phosphocholine, a prerequisite for the biosynthesis of a primary phospholipid phosphatidylcholine. However, the primary choline kinase and its role in plant growth remained elusive in seed plants. Here

The alpha-ketoglutarate-dependent hydroxylases and halogenases employ similar reaction mechanisms involving hydrogen-abstracting Fe(IV)-oxo (ferryl) intermediates. In the halogenases, the carboxylate residue from the His(2)(Asp/Glu)(1) "facial triad" of iron ligands found in the hydroxylases is replaced by alanine, and a halide ion
