Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy

open access: yesAllergy, EarlyView.
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

From hepatic to hematopoietic: LRH‐1's expanding cellular repertoire to the immune system

open access: yesThe FEBS Journal, EarlyView.
The nuclear receptor LRH‐1 is a well‐characterized regulator of endodermal tissue. Yet, increasing evidence indicates that LRH‐1, although expressed at low levels, is also a critical regulator of the hematopoietic system. LRH‐1 regulates the immune system by contributing to immune cell‐specific functions.

L-glutaminase synthesis by Klebsiella pneumoniae (AS KP 23) isolated from clinical strain, and its efficacy against human hepatocellular and breast cancer cell lines

open access: yesBMC Microbiology
Background Cancer is a major cause of morbidity and mortality worldwide. The proliferation of cancer cells depends largely on glutamine for survival and proliferation.

Occurrence of Glutaminase in Endamoeba histolytica [PDF]

open access: yesNature, 1957
THE existence of glutaminase in bacteria has been demonstrated1–3. However, to our knowledge no work has been done on other micro-organisms such as Protozoa. Little is known on the enzymatic make-up of Endamoeba histolytica 4. Recently, proteolytic enzymes were demonstrated in the amoebae5. Since a method became available for obtaining large quantities

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

open access: yesThe FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

open access: yesThe FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

open access: yesThe FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Hypoxia‐induced vulnerability of the somatosensory nervous system

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Estrogen Receptor Beta Activation Coordinates Liver Lipid Remodeling and Metabolic Fluxes, Preventing Lipotoxicity

open access: yesComprehensive Physiology, Volume 16, Issue 4, August 2026.
ERβ activation restores glucose and lipid homeostasis by remodeling the hepatic lipidome. Mechanistically, it promotes complete fatty acid oxidation and decreases Acetyl‐CoA levels, leading to reduced ketogenesis and lipotoxicity, as demonstrated through in vivo and in vitro approaches.

Physapubescin B From Physalis: A Food‐Derived Withanolide for Cancer Chemoprevention and Nutraceutical Development

open access: yeseFood, Volume 7, Issue 4, August 2026.
Physapubescin B may interfere with multiple cancer‐associated signaling pathways by inhibiting Ras/Raf/mitogen‐activated protein kinase kinase/extracellular signal‐regulated kinase (Ras/Raf/MEK/ERK) signaling and vascular endothelial growth factor (VEGF)‐dependent angiogenesis.
