Untargeted metabolomics analysis as a potential screening tool for 3-methylglutaconic aciduria syndromes.

Mol Genet Metab

December 2024

Department of Molecular and Human Genetics, Baylor College of Medicine, Houston, TX, USA; Texas Children's Hospital, Houston, TX, USA; BCM-CUHK Center of Medical Genetics, Prince of Wales Hospital, Hong Kong, China.

The 3-methylglutaconic aciduria (3-MGA-uria) syndromes comprise a heterogeneous group of inborn errors of metabolism defined biochemically by detectable elevation of 3-methylglutaconic acid (3-MGA) in the urine. In type 1 (or primary) 3-MGA-uria, distal defects in the leucine catabolism pathway directly cause this elevation. Secondary 3-MGA-uria syndromes, however, are unrelated to leucine metabolism-specific defects but share a common biochemical phenotype of elevated 3-MGA.

Lung metastases occur in up to 54% of patients with metastatic tumours. Contributing factors to this high frequency include the physical properties of the pulmonary system and a less oxidative environment that may favour the survival of cancer cells. Moreover, secreted factors from primary tumours alter immune cells and the extracellular matrix of the lung, creating a permissive pre-metastatic environment primed for the arriving cancer cells.

Cuproptosis is a recently discovered form of regulated cell death triggered by mitochondrial copper accumulation and proteotoxic stress. Here, we provide the first evidence that glutathione (GSH), a major non-protein thiol in cells, acts as a cuproptosis inhibitor in pancreatic ductal adenocarcinoma (PDAC) cells. Mechanistically, GSH inhibits cuproptosis by chelating copper, contrasting its role in blocking ferroptosis by inhibiting lipid peroxidation.

Article Synopsis
  • Ascorbate (vitamin C) decreases the function of hematopoietic stem cells (HSCs) and helps prevent leukemia by enhancing the activity of the Tet2 tumor suppressor.
  • Deleting the Slc23a2 transporter from hematopoietic cells caused a significant drop in ascorbate levels within HSCs and multipotent progenitors (MPPs) but did not affect overall plasma ascorbate levels.
  • This deficiency led to increased reconstitution and self-renewal capabilities of HSCs and MPPs when transplanted into irradiated mice, particularly in their quiescent states, indicating that low ascorbate levels may enhance their long-term potential.
