MetabolomicsPFKFB3 activates CAD to enhance de novo pyrimidine synthesis for cell growth

Aerobic glycolysis, termed the Warburg effect, is one of the aberrant metabolic pathways in highly proliferating cells. Glycolysis provides glycolytic metabolites to support the generation of biomass, such as nucleotides, amino acids, and lipids. To date, research on the direct interactions betwe...

MetabolomicsDe Novo Pyrimidine Synthesis Is a Collateral Metabolic Vulnerability in NF2-deficient Mesothelioma

Pleural mesothelioma (PM) is one of the deadliest cancers, with limited therapeutic options due to its therapeutically intractable genome, which is characterized by the functional inactivation of tumor suppressor genes (TSGs) and high tumor heterogeneity, including diverse metabolic adaptations. ...

ProteomicsDe novo pyrimidine biosynthetic complexes support cancer cell proliferation and ferroptosis defense
De novo pyrimidine biosynthesis is achieved by cytosolic enzymes, CAD and UMPS, and mitochondrial DHODH. However, how these enzymes are orchestrated remains enigmatical. Here, we show that cytosolic aspartate-producing GOT1 clusters with CAD and UMPS. This cytosolic cluster then connects with DHODH,...

MetabolomicsRich organic nitrogen impacts clavulanic acid biosynthesis through the arginine metabolic pathway in Streptomyces clavuligerus F613-1

Clavulanic acid (CA) is the preferred clinical drug for the treatment of infections by β-lactam antibiotic-resistant bacteria. CA is produced by Streptomyces clavuligerus, and although there have been many reports on the effects of carbon and nitrogen sources on CA production, the mechan...

ProteomicsProteomics Analysis of the UMK2 Mutation in Arabidopsis thaliana seeds
We compared the proteome of dry as well as germinating seeds of Arabidopsis thaliana wild type Col-0 with the respective proteomes from an umk2 (AT4G25280) frameshift mutant. Germinating seeds were incubated for 48 hours in 1/2-MS medium in Petri dishes at 4 degree Celsius followed by 24 hours of a...

TranscriptomicsEctopic expression of cytosolic DHODH uncouples de novo pyrimidine biosynthesis from mitochondrial electron transport
Dihydroorotate dehydrogenase (DHODH) is a rate-limiting enzyme of de novo pyrimidine synthesis. In most eukaryotes, this enzyme is bound to the inner mitochondrial membrane, where it couples orotate synthesis to ubiquinone reduction. As ubiquinone must be regenerated by respiratory complex III, pyri...
