MetabolomicsSystem Xc- exacerbates metabolic stress under glucose depletion in oral squamous cell carcinoma

OBJECTIVE: Emerging evidence suggests that glucose depletion (GD)-induced cell death depends on system Xc-, a glutamate/cystine antiporter extensively studied in ferroptosis. However, the underlying mechanism remains debated. Our study confirmed the correlation between system Xc...

MetabolomicsIsotopomer analysis of MCF-7 breast cancer cell line incubated with 13C labelled glucose (GC-MS assay)
MS and NMR are two of the most powerful spectroscopic techniques used in the field of fluxomics, to analyze the flux distributions in cellular metabolomic pathways. Both of them possess pros and cons, such as, MS being the most sensitive and low-cost technique, while needs extensive sample processin...

MetabolomicsSnail reprograms glucose metabolism by repressing PFKP allowing cancer cell survival under metabolic stress
Dynamic regulation of glucose flux between aerobic glycolysis and the pentose phosphate pathway (PPP) during epithelial-mesenchymal transition (EMT) is not well-understood. Here we show that Snail (SNAI1), a key transcriptional repressor of EMT, regulates glucose flux toward PPP, allowing cancer cel...

MetabolomicsIntegrated Proteomic and Metabolomic Analyses Show Differential Effects of Glucose Availability in Marine Synechococcus and Prochlorococcus

We compared changes induced by the addition of 100 nM and 5 mM glucose on the proteome and metabolome complements in Synechococcus sp. strains WH8102, WH7803, and BL107 and Prochlorococcus sp. strains MED4, SS120, and MIT9313, grown either under standard light conditions or in d...

MetabolomicsHuman gut microbiota and plasma metabolomics in Mn-glucose metabolism correlation

Previous epidemiological and laboratorial studies have demonstrated a close relationship between plasma manganese (Mn) levels and type 2 diabetes (T2D), however, the underlying mechanism remains undisclosed. In this study, we employed a comprehensive approach that integrated fecal 16S rRNA sequen...

MetabolomicsSpecific biomarkers for stochastic division patterns and starvation-induced quiescence under limited glucose levels in fission yeast
Glucose as a source of energy is centrally important to our understanding of life. We investigated the cell division-quiescence behavior of the fission yeast Schizosaccharomyces pombe under a wide range of glucose concentrations (0-111 mM). The mode of S. pombe cell division under a microfluidic per...

MetabolomicsIncreased glucose availability sensitizes pancreatic cancer to chemotherapy
Pancreatic cancer (Pancreatic Ductal Adenocarcinoma; PDAC) is highly resistant to chemotherapy. Effective alternative therapies have yet to emerge, and therefore, chemotherapy remains the best available systematic treatment. The discovery of safe and available adjuncts that can improve chemotherapeu...

MetabolomicsNQO1 protects obese mice through improvements in glucose and lipid metabolism.
Chronic nutrient excess leads to metabolic disorders and insulin resistance. Activation of stress-responsive pathways via Nrf2 activation contributes to energy metabolism regulation. Here, inducible activation of Nrf2 in mice and transgenesis of the Nrf2 target, NQO1, conferred protection from diet-...

MetabolomicsExploring the Glucose Fluxotype of the E. coli y-ome Using High-Resolution Fluxomics
We have developed a robust workflow to measure high-resolution fluxotypes (metabolic flux phenotypes) for large strain libraries under fully controlled growth conditions. This was achieved by optimizing and automating the whole high-throughput fluxomics process and integrating all relevant software ...

MetabolomicsProteome allocations change linearly with the specific growth rate of Saccharomyces cerevisiae under glucose limitation

Saccharomyces cerevisiae is a widely used cell factory; therefore, it is important to understand how it organizes key functional parts when cultured under different conditions. Here, we perform a multiomics analysis of S. cerevisiae by culturing the strain with a wide range of s...
