Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review
Food Frontiers, EarlyView.Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Metabolic responses to pyruvate kinase deletion in lysine producing
Microbial Cell Factories, 2008 Background Pyruvate kinase is an important element in flux control of the intermediate metabolism. It catalyzes the irreversible conversion of phosphoenolpyruvate into pyruvate and is under allosteric control.

Diatom Proteomics Reveals Unique Acclimation Strategies to Mitigate Fe Limitation [PDF]
, 2015 Phytoplankton growth rates are limited by the supply of iron (Fe) in approximately one third of the open ocean, with major implications for carbon dioxide sequestration and carbon (C) biogeochemistry.

Regulation of pyruvate dehydrogenase complex: Dancing to different drums in cancer
International Journal of Cancer, EarlyView.Abstract Mechanisms governing the regulation of pyruvate dehydrogenase complex (PDC) are markedly modified in cancer cells compared to normal cells. PDC activity in normal cells is controlled by the reversible phosphorylation of three serine residues by dedicated kinases and phosphatases.

Experiments on the carboxylase of pea roots [PDF]
, 1941 It is known that vitamin B1 is a growth factor for numerous bacteria and fungi including the yeasts (see the summary in Koser and Saunders (1938)). It has also been demonstrated that vitamin B1 is essential for the growth of the isolated roots of higher ...

Glioma Cells with the IDH1 Mutation Modulate Metabolic Fractional Flux through Pyruvate Carboxylase
PLoS ONE, 2014 Background Over 70% of low-grade gliomas carry a heterozygous R132H mutation in the gene coding for isocitrate dehydrogenase 1 (IDH1). This confers the enzyme with the novel ability to convert α-ketoglutarate to 2-hydroxyglutarate, ultimately leading to ...

Technologies and Strategies for Metabolic and Molecular Imaging With Hyperpolarized MRI
Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Conventional Magnetic Resonance Imaging (MRI) offers limited sensitivity for direct metabolic and molecular imaging using non‐proton nuclei due to low thermal nuclear spin polarization. Hyperpolarization (HP) technologies increase nuclear spin polarization by several orders of magnitude, overcoming this limitation to enable in vivo studies of ...
