To maintain amino acid nutrition for tumor growth, the expression of the LAT1 ( SLC7A5 ) transporter is controlled by the pro-carcinogenic transcription factors c-Myc (Yue et al., 2017), HIF2 (Elorza et al., 2012), and NOTCH (Grzes et al., 2017), as well as the post-transcriptional regulator miR-126 (Miko et al., 2011)

Insulin has been administered to patients to try to improve symptoms of neurodegeneration (209, 210) and has been shown to protect cells from A induced death (211213)

It is the reason relatively few peptides achieve approval despite the large number that show promise in early research

However, emerging evidence suggests that building up cysteine-derived antioxidant defense systems also comes at an enormous cost for SLC7A11 high cancer, as such efforts require a significant investment of cellular resources, including glutamate export for exchange of cystine import and NADPH supply to reduce cystine to cysteine in the cytosol, resulting in glucose- and glutamine-dependency in SLC7A11 high cancer cells

The effects happen over weeks and months, not days
