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...

MetabolomicsRegional HNSCC metabolomics reveals widespread changes to one-carbon metabolism and S-adenosylmethionine metabolism across tumour core, tumour edge and adjacent non-tumour tissues

Cancer, including head and neck squamous cell carcinoma (HNSCC), induces changes to metabolism that drive the disease. Regional metabolomics can help to understand metabolic variation across the tumour including changes near the tumour core, where hypoxia is likely more pronounced. We apply ultra...

MetabolomicsPhotorespiration is linked to DNA methylation by formate as one-carbon source.
DNA methylation is a key epigenetic modification regulating genome organization, stability, and gene expression. Stable DNA methylation critically relies on methyl groups provided through folate-mediated one-carbon (C1) metabolism, yet the origin and regulation of C1 supply remain elusive. Here we d...

MetabolomicsPositional Enrichment by Proton Analysis (PEPA): a One-Dimensional 1H-NMR Approach for 13C Stable Isotope Tracer Studies in Metabolomics
A novel metabolomics approach for NMR-based stable isotope tracer studies called PEPA is presented, and its performance validated using human cancer cells. PEPA detects the position of carbon label in isotopically enriched metabolites and quantifies fractional enrichment by indirect determination of...

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...

ProteomicsSpic a specific marker of ground state pluripotency that regulates one carbon metabolism
Understanding mechanisms of epigenetic regulation in embryonic stem cells (ESCs) is of fundamental importance for stem cell and developmental biology. Here we identify Spic, a member of the ETS family of transcription factors, as a specific marker of ground state pluripotency. We show that Spic is r...

MetabolomicsIntergenerational Association of Gut Microbiota and Metabolism with Perinatal Folate Metabolism and Neural Tube Defects (Feces metabolomics)

Maternal folic acid intake is crucial for the development of the offspring's nervous system, and folic acid metabolism disorders during pregnancy lead to neural tube defects (NTDs) in the fetus. Folic acid and vitamins biosynthesis is a major biochemical feature of gut microbiota. The complex and...

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...

GenomicsRole of RccR in the transcriptional control of primary carbon metabolism in Pseudomonas
To characterise the RccR regulon, we performed a ChIP-seq assay using a polyclonal RccR antiserum on SBW25 WT/rccR strains grown in minimal pyruvate and glycerol media. We were able to identify 8 RccR binding sites from this experiment including one in the rccR promoter region itself. The peaks iden...

MetabolomicsFruit setting rewires central metabolism via gibberellin cascades
Fruit set is the process whereby ovaries develop into fruits after pollination and fertilization. The process is induced by the phytohormone gibberellin (GA) in tomatoes, as determined by the constitutive GA response mutant procera However, the role of GA on the metabolic behavior in fruit-setting o...
