592-P: Epidermal Nrf2 Orchestrates Tissue Regeneration through Direction Regulation of Ccl2

Diabetic ulcers are costly chronic wounds and are the leading cause of lower-extremity amputations. Dysfunctional redox balance underlies a key part of diabetic wound repair pathology that results from misregulation of master antioxidant gene regulator Nrf2. While Nrf2 regulation is relevant for wound repair, how Nrf2 onsets a regenerative response is unclear. Using in-depth analyses, we uncover Nrf2 expression in keratinocytes to be vital for physiologic wound repair. In vivo spatio-temporal analysis shows deregulated nuclear translocation of Nrf2 in diabetic wound keratinocytes (WT: 96.97%±3.6%; Db: 22.50%±16.4%; p Disclosure A.P. Villarreal Ponce: None. M.
