Modulation of Subcellular Redox Homeostasis with Trialkylphosphines

Jade Noémie Nam Nguyen

Redox homeostasis is essential for cell function and its disruption is associated with multiple pathologies. Redox balance is largely regulated by the relative concentrations of reduced (GSH) and oxidized (GSSG) glutathione. In eukaryotic cells, this ratio ...
