Description

Nrf2 once activated, binds to the antioxidant response element (ARE) located at the regulatory regions of the genes of the antioxidant enzymes and induces transcription of the antioxidants genes (Morinho et al., 2014)

However, given the lack of an enrichment step in the SICyLIA approach, it may be less suitable for the analysis of low abundance proteins and cases where the stoichiometry of oxidation is low

The blocking of the cycle by low ATP is more likely associated with a decrease of cysteine bioavailability

Studies suggest that using a PEG tube at the right time may extend life by 36 months (Guillemin et al., 2022)

However, GSH levels were not associated with OM severity, indicating that antioxidant upregulation may not directly translate into clinical mucositis outcomes 38,39
