Retracing from Outcomes to Causes: NRF2-Driven GSTA4 Transcriptional Regulation Controls Chronic Inflammation and Oxidative Stress in Atopic Dermatitis Recurrence.

Abstract
Atopic dermatitis (AD), a chronic and recurrent inflammatory skin disorder, presents a high incidence and imposes a substantial economic burden. Preventing its recurrence remains a significant challenge in dermatological therapy owing to poorly understood underlying mechanisms. In our study, we adopted a strategy of tracing the mechanisms of recurrence from clinical outcomes. We developed a mouse model of recurrent AD and applied clinically validated treatment regimens. Transcriptomic analyses revealed a pronounced enrichment in the glutathione metabolic pathway in the treated group. Through integrated bioinformatics and in vivo validation, we identified glutathione S-transferase alpha 4 (GSTA4) as a pivotal mediator in AD recurrence. Immunohistochemical analysis demonstrated decreased GSTA4 expression in lesions from patients with AD. Functionally, in vitro overexpression of GSTA4 significantly curtailed AD-like inflammatory responses and ROS production. Moreover, we discovered that NRF2 transcriptional activity regulates GSTA4 expression and function. Our treatment notably augmented NRF2-mediated GSTA4 transcription, yielding pronounced anti-inflammatory and ROS-neutralizing effects. Conclusively, our findings implicate GSTA4 as a critical factor in the recurrence of AD, particularly in the context of oxidative stress and chronic inflammation. Targeting the NRF2-GSTA4 axis emerges as a promising anti-inflammatory and antioxidative strategy for preventing AD recurrence.

Exploration of costunolide derivatives as potential anti-inflammatory agents for topical treatment of atopic dermatitis by inhibiting MAPK/NF-κB pathways. Bioorg Chem 2024; 143:107054. [PMID: 38157670 DOI: 10.1016/j.bioorg.2023.107054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 12/12/2023] [Accepted: 12/21/2023] [Indexed: 01/03/2024]
Abstract
Atopic dermatitis (AD) is a common inflammatory disease and it is very difficult to treat. In the present work, a series of costunolide derivatives have been prepared, and in vitro and in vivo anti-inflammatory activities have evaluated. The results showed that most derivatives displayed good inhibition of NO generation with low cytotoxicity, and 7d could inhibit the phosphorylation of P38, P65 NF-κB and IκB-α in LPS-induced RAW264.7 model. The in vivo researches showed that 7d could improve skin injury symptoms, decrease Th2-type cytokine levels, inhibit HIS levels, alleviate scratching and repaire the damaged skin barrier through the inhibition of phosphorylation of MAPK and NF-κB signaling pathways on MC903-induced AD model. Therefore, costunolide derivatives may be new potent anti-AD agents for further study.
