This is exemplified in two independent studies showing that β-cell compensation for dietary insulin resistance and obesity is regulated by the nuclear factor erythroid 2-related factor (NRF2), a basic leucine-zipper transcription factor that acts through its key targets including superoxide dismutase, catalase, and glutathione peroxidase 1 to defend cells against oxidative stress (68, 69, 70). This evidence concerns the gene NFE2L2 and obesity disorder.
