Post-translational regulation of retinal IMPDH1 in vivo to adjust GTP synthesis to illumination conditions

eLife, 2020
We report the in vivo regulation of Inosine-5´-monophosphate dehydrogenase 1 (IMPDH1) in the retina. IMPDH1 catalyzes the rate-limiting step in the de novo synthesis of guanine nucleotides, impacting the cellular pools of GMP, GDP and GTP.

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Nucleoside Analogs in ADAR Guide Strands Enable Editing at 5′-GA Sites

Biomolecules
Adenosine Deaminases Acting on RNA (ADARs) are members of a family of RNA editing enzymes that catalyze the conversion of adenosine into inosine in double-stranded RNA (dsRNA).

An inosine 5′-monophosphate dehydrogenase 2 single-nucleotide polymorphism impairs the effect of mycophenolic acid [PDF]

The Pharmacogenomics Journal, 2009
Mycophenolic acid (MPA) is a selective inhibitor of inosine 5'-monophosphate dehydrogenase (IMPDH), the rate-limiting enzyme of de novo synthesis of guanine nucleotides. The isoenzyme IMPDH2 predominates in activated lymphocytes, and its inhibition by MPA is part of standard immunosuppressive regimens. Yet, there are significant unexplained differences

Effect of Heat Treatment on the Flavor Characteristics of Vacuum Freeze‐Dried Pacific White Shrimp (Litopenaeus vannamei)

eFood, Volume 7, Issue 2, April 2026.
A post‐freeze‐drying heat treatment at 150°C optimizes shrimp flavor by boosting umami compounds and generating roasted aromas via the Maillard reaction. This strategy successfully bridges the texture‐flavor trade‐off, enabling premium ready‐to‐eat shrimp products.

Dietary essential oils modulate post‐mortem oxidative damage in trout fillets exposed to slaughter stress during frozen storage

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3686-3695, April 2026.
Abstract BACKGROUND Slaughter is a critical phase in aquaculture that can severely compromise both animal welfare and product quality. Stress responses triggered during this stage may accelerate post‐mortem biochemical degradation and promote oxidative damage in fish fillets. Essential oils, known for their antioxidant and anti‐inflammatory properties,

A nucleotide-controlled conformational switch modulates the activity of eukaryotic IMP dehydrogenases

Scientific Reports, 2017
Inosine-5′-monophosphate dehydrogenase (IMPDH) is an essential enzyme for nucleotide metabolism and cell proliferation. Despite IMPDH is the target of drugs with antiviral, immunosuppressive and antitumor activities, its physiological mechanisms of ...

Comprehensive Profiling of N6‐methyladnosine (m6A) Readouts Reveals Novel m6A Readers That Regulate Human Embryonic Stem Cell Differentiation

Advanced Science, Volume 13, Issue 18, 27 March 2026.
This research deciphers the m6A transcriptome by profiling its sites and functional readout effects: from mRNA stability, translation to alternative splicing, across five different cell types. Machine learning model identifies novel m6A‐binding proteins DDX6 and FXR2 and novel m6A reader proteins FUBP3 and L1TD1.

Affinity Chromatography on Immobilised Nucleotides [PDF]

European Journal of Biochemistry, 1980
The synthesis and characterisation of two IMP analogues, 8‐(6‐aminohexyl)‐ionosine 5′‐monophosphate, Ahx8IMP, and inosine 2′,3′‐O‐[1‐(6‐aminohexyl)‐levulinic acid amide]‐acetal 5′‐monophosphate, (AhxLvn)2′,3′ IMP, is described. These analogues were attached to CNBr‐activated agarose through the terminal amino group of the spacer molecule.

Multi‐Tissue Genetic Regulation of RNA Editing in Pigs

Advanced Science, Volume 13, Issue 17, 23 March 2026.
This study presents the first multi‐tissue map of RNA editing and its genetic regulation in pigs. By integrating RNA editing profiles, edQTL mapping, GWAS, and cross‐species comparisons, this work establishes RNA editing as a distinct regulatory layer linking genetic variation to complex traits, highlighting its functional and evolutionary significance.
