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...

MetabolomicsPollutant depletion by gut bacterial communities
Per- and polyfluoroalkyl Substances (PFAS) – the so-called ‘forever chemicals’ – are a major cause of environmental and health concern due to their toxicity and long-term persistence. Yet, no efficient mechanisms for their removal have been identified. Here we report the potential of two communities...

MetabolomicsNutrient depletion and systems-wide metabolic shifting in polymer-producing wastewater bacterium

Inorganic nutrient deficiency stimulates polymer synthesis in bacterial producers relevant to wastewater treatment and biotechnology, but the metabolic mechanisms are poorly understood. Here, using a quantitative multi-omics analysis of the wastewater isolate Comamonas testosteroni durin...

MetabolomicsNucleotide depletion signals early-stage soil stable carbon collapse in anthropogenically disturbed alpine ecosystems
Anthropogenic disturbances are a primary cause of soil organic carbon (SOC) destabilization in alpine ecosystems. However, effective management is hindered by a """"response delay"""" of macro metrics used to characterize stable carbon pools (e.g., microbial necromass carbon and aggregate associated...

MetabolomicsBMAL1-depletion remodels ceramide metabolism to regulate ferroptosis and sorafenib chemosensitivity in acute myeloid leukemia
Acute myeloid leukemia (AML) is a hematologic malignancy with a poor prognosis. We discovered that BMAL1 is a ferroptosis suppressor. Furthermore, it was also found to be overexpressed in AML patients, affecting the cell cycle and promoting tumor cell growth and progression. In this study, we furthe...

MetabolomicsThe accumulation of methylglyoxal and acrolein leads to arginine depletion causing hyperglycemia and renal abnormalities

There is growing evidence to support the idea that the accumulation of reactive carbonyl species plays a significant causal role in the pathogenesis of ageing, cardiovascular diseases, diabetes and its complications. Among reactive carbonyl species, methylglyoxal and acrolein, detoxified by glyox...

MetabolomicsEnterotoxigenic Bacteroides fragilis exacerbates alcoholic liver disease progression through kynurenine mediated AMPK signaling inhibition and retinoic acid depletion

Abstract Background & Aims: Alcoholic liver disease (ALD) pathogenesis involves gut microbiota dysbiosis, but specific pathobionts and mechanisms remain unclear. This study investigated the role of patient-derived enterotoxigenic Bacteroides fragilis (ETBF) in ALD progression and its underlyi...

MetabolomicsArginine depletion-induced autophagy and metabolic dysregulation are involved in the disease severity of hand, foot, and mouth disease
Amino acid metabolism provides significant insight into the development and prevention of many viral diseases. Therefore, the present study aimed to compare the amino acid profiles of hand, foot, and mouth disease (HFMD) patients with those of healthy individuals and to further reveal the molecular ...
