TLDR Activating Nrf2 in skin cells causes skin disease similar to chloracne in mice.
The study demonstrated that prolonged activation of the Nrf2 transcription factor in mouse keratinocytes led to skin abnormalities resembling chloracne/MADISH, characterized by sebaceous gland hyperplasia, hyperkeratosis, acanthosis, hair loss, and large keratinized skin cysts. These effects were linked to increased expression of Nrf2 target genes such as Epgn, Slpi, and Sprr2d, which were also upregulated in human keratinocytes in an Nrf2-dependent manner. The findings highlighted the need to consider these potential side effects when using Nrf2-activating compounds for skin protection and cancer prevention.
