Role of long non-coding RNAs on the regulation of Nrf2 in chronic diseases

Studies have identified dysregulated long non-coding RNA (lncRNA) in several diseases at transcriptional, translational, and post-translational levels. Although our mechanistic knowledge on the regulation of lncRNAs is still limited, one of the mechanisms of action attributed is binding and regulating transcription factors, thus controlling gene expression and protein function. One such transcription factor is nuclear factor erythroid 2-related factor 2 (Nrf2), which plays a critical biological role in maintaining cellular homeostasis at multiple levels in physiological and pathophysiological conditions. The levels of Nrf2 were found to be down-regulated in many chronic diseases, signifying that Nrf2 can be a key therapeutic target. Few lncRNAs like lncRNA ROR, ENSMIJST00000125413, lncRNA ODRUL, Nrf2-1ncRNA have been associated with the Nrf2 signaling pathway in response to various stimuli, including stress. This review discusses the regulation of Nrf2 in different responses and the potential role of specific lncRNA in modulating its transcriptional activities. This review further helps to enhance our knowledge on the regulatory role of the critical antioxidant transcription factor, Nrf2.

Automated summary

Studies have shown dysregulated lncRNAs in various diseases, with mechanisms potentially involving regulation of transcription factors and gene expression. Nrf2, a critical transcription factor, maintains cellular homeostasis in physiological and pathophysiological conditions, and is associated with multiple chronic diseases. Specific lncRNAs like ROR and ODRUL are linked to the Nrf2 signaling pathway. This review explores the regulation of Nrf2 in different responses and the role of lncRNAs in modulating its activities.
