The Keap1/NRF2/ARE pathway is critical for melanocyte protection against oxidative damage; however, the role of Cullin-3 (CUL3), a scaffold for E3 ubiquitin ligases that regulate NRF2 degradation, and its interplay with inflammatory mediators in vitiligo pathogenesis are underexplored. The gene discussed is NFE2L2; the disease is vitiligo.
