-Glutamine supplementation promotes an improved energetic balance in Walker-256 tumor–bearing rats

open access: yesTumor Biology, 2017
We evaluated the effects of supplementation with oral l -glutamine in Walker-256 tumor–bearing rats. A total of 32 male Wistar rats aged 54 days were randomly divided into four groups: rats without Walker-256 tumor, that is, control rats (C group ...

The PEP—pyruvate—oxaloacetate node as the switch point for carbon flux distribution in bacteria: We dedicate this paper to Rudolf K. Thauer, Director of the Max-Planck-Institute for Terrestrial Microbiology in Marburg, Germany, on the occasion of his 65th birthday [PDF]

open access: yes, 2017
In many organisms, metabolite interconversion at the phosphoenolpyruvate (PEP)-pyruvate-oxaloacetate node involves a structurally entangled set of reactions that interconnects the major pathways of carbon metabolism and thus, is responsible for the ...

Which way does the citric acid cycle turn during hypoxia? The critical role of alpha-ketoglutarate dehydrogenase complex [PDF]

open access: yes, 2013
The citric acid cycle forms a major metabolic hub and as such it is involved in many disease states involving energetic imbalance. In spite of the fact that it is being branded as a "cycle", during hypoxia, when the electron transport chain does not ...

Phosphate Resupply Differentially Impacts the Shoot and Root Proteomes of Arabidopsis thaliana Seedlings

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1598-1616, March 2026.
ABSTRACT Phosphate (Pi) is an essential macronutrient for plant development that is often limited in soil. Plants have evolved dynamic biochemical, physiological and morphological adaptations to cope with Pi deficiency, known as the Pi starvation response (PSR).

Transcriptomic response in Acropora muricata under acute temperature stress follows preconditioned seasonal temperature fluctuations

open access: yesBMC Research Notes, 2018
Objective Global climate change has resulted in the decline of health and condition of various coral reefs worldwide. Here, we describe expression profiles of Acropora muricata collected during opposing seasons in Otsuki, Kochi, Japan to define the ...

Transcriptomic changes associated with PCK1 overexpression in hepatocellular carcinoma cells detected by RNA-seq

open access: yesGenes and Diseases, 2020
Phosphoenolpyruvate carboxykinase 1 (PCK1), a step limiting enzyme of gluconeogenesis, is downregulated in hepatocellular carcinoma (HCC). Overexpression of PCK1 has been shown to suppress hepatoma cell growth, but the underlying mechanism remains ...

The relative importance of kinetic mechanisms and variable enzyme abundances for the regulation of hepatic glucose metabolism – insights from mathematical modeling [PDF]

open access: yes, 2016
Background Adaptation of the cellular metabolism to varying external conditions is brought about by regulated changes in the activity of enzymes and transporters.

Ginsenoside Rg1 as a Multifunctional Therapeutic Agent: Pharmacological Properties, Molecular Mechanisms and Clinical Perspectives in Complementary Medicine

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Ginsenoside Rg1 (Rg1) from Panax ginseng shows multifunctional health effects. Although oral bioavailability is low and blood–brain barrier (BBB) penetration is limited, delivery systems such as liposomes and nanoparticles may improve exposure. Rg1 reduces inflammation/oxidative stress by inhibiting nuclear factor‐κB (NF‐κB) signaling and reactive ...

Largely Distinct Post‐Translational Modifications Differentiate Skeletal Muscle Wasting Caused by Cancer, Dexamethasone and Aging

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Skeletal muscle wasting and weakness are prominent disease features. Originally considered to arise from common transcriptional changes, recent analyses demonstrated that different stimuli induce muscle wasting via largely distinct mRNA and protein changes.

The Subgingival Host–Microbial Landscape in Mothers With Periodontitis and Their At‐Risk Offspring

open access: yesJournal of Clinical Periodontology, Volume 53, Issue 2, Page 201-213, February 2026.
ABSTRACT Aim To evaluate the subgingival proteome and microbiome of mothers with periodontitis and their offspring, thereby assessing signatures of periodontal diseases. Methods Forty participants in four groups were included: mothers with periodontitis and their offspring, as well as periodontally healthy mothers and their offspring.
