MetabolomicsHierarchical Carbon Metabolism in Iron-Deficient Bacteria Favors Iron-Scavenging Strategy

High-affinity iron (Fe) scavenging compounds, or siderophores, are widely employed by soil bacteria to survive scarcity in bioavailable Fe. Siderophore biosynthesis relies on cellular carbon metabolism, despite reported decrease in both carbon uptake and Fe-containing metabolic proteins in Fe-def...

MetabolomicsRegulatory mechanisms for aromatic carbon metabolism in Comamonas testosteroni
Widely reported discrepancies between metabolic flux and transcripts or enzyme levels in bacterial metabolism imply complex regulation mechanisms need to be considered, especially in new bacterial platforms for bioremediation and bioproduction. Comamonas testosteroni strains, which metabolize variou...

MetabolomicsThe oncoprotein SET promotes serine-derived one-carbon metabolism by regulating SHMT2 enzymatic activity
Cancer cells frequently reprogram one-carbon metabolic pathways to fulfill their vigorous demands of biosynthesis and antioxidant defense for survival and proliferation. Dysfunction of oncogenes or tumor suppressor genes is critically involved in this process, but the precise mechanisms by which can...

MetabolomicsSerine and 1-carbon metabolism are required for HIF-mediated protection against retinopathy of prematurity
We determined which metabolic pathways are activated by hypoxia-inducible factor 1-mediated (HIF-1-mediated) protection against oxygen-induced retinopathy (OIR) in newborn mice, the experimental correlate to retinopathy of prematurity, a leading cause of infant blindness. HIF-1 coordinates the chang...

MetabolomicsTranscobalamin 2 orchestrates monocyte proliferation and TLR4-driven inflammation in systemic lupus erythematosus via folate one-carbon metabolism

BACKGROUND: SLE is a complex autoimmune disease with deleterious effects on various organs. Accumulating evidence has shown abnormal vitamin B12 and one-carbon flux contribute to immune dysfunction. Transcobalamin II (TCN2) belongs to the vitamin B12-binding protein family respon...

MetabolomicsMultiomics of tomato glandular trichomes reveals distinct features of central carbon metabolism supporting high productivity of specialized metabolites
Glandular trichomes are metabolic cell factories with the capacity to produce large quantities of secondary metabolites. Little is known about the connection between central carbon metabolism and metabolic productivity for secondary metabolites in glandular trichomes. To address this gap in our know...

MetabolomicsExtracellular-acidosis restricts one-carbon metabolism and preserves T cell stemness
The accumulation of acidic metabolic waste products within the tumor microenvironment profoundly inhibits effector functions of tumor-infiltrating lymphocytes (TILs). However, it is unclear whether extracellular-acidosis impacts T cell metabolic fitness and differentiation status. Here, we surprisin...

MetabolomicsCharacteristics of myocardial structure and central carbon metabolism during the early and compensatory stages of cardiac hypertrophy
Cardiac hypertrophy is a classical forerunner of heart failure and myocardial structural and metabolic remodeling are closely associated with cardiac hypertrophy. We aim to investigate the characteristics of myocardial structure and central carbon metabolism of cardiac hypertrophy at different stage...

MetabolomicsMetabolic Response of a Chemolithoautotrophic Archaeon to Carbon Limitation

The ubiquitously distributed ammonia-oxidizing archaea generate energy from ammonia and build cell mass from inorganic carbon sources, thereby contributing to both the global nitrogen and carbon cycles. However, little is known about the regulation of their predicted core carbon metabolism. A the...
