Abstract

fetched live from OpenAlex

BACKGROUND: Nuclear factor-erythroid related factor-2 (Nrf2) is a master regulator of transcriptional activation of anti-oxidants in cells. Similarly, heme oxygenase (HO) is a cytoprotective protein with anti-oxidant effects. This review article will shed more light on the interaction between Nrf2 and HO. METHODS AND RESULTS: A PubMed search was done for recent articles on Nrf2 and HO. These studies suggested that under normal physiological conditions, Nrf2 is bound within the cytoplasm to its repressor, Kelch-like ECHassociated protein (Keap1), an oxidative stress sensor. Upon activation, Nrf2 translocates to the nucleus and binds to the antioxidant-response-element located at the promoter region of some anti-oxidants including the cytoprotective protein HO. Since the HO-1 gene harbors binding site for Nrf2, mutual stimulatory and regulatory effects between Nrf2 and HO-1 have been reported. Accordingly, the interaction between Nrf2 and HO-1 has been implicated in the regulation of many physiological anti-oxidants including superoxide dismutases, catalase, glutathione S-transferase, peroxidase, NAD(P)H quinone oxidoreductase, and thioredoxin. CONCLUSION: Although an overwhelming body of evidence has underscored unique anti-oxidant attributes of HO- 1 and Nrf2, emerging evidence suggests that the cytoprotective activities of Nrf2 and HO-1 may be attributed, at least in part, to the potentiation of different anti-oxidants in physiological mileu. Since Nrf2 binds to the antioxidant responsive element of HO-1, the coordinated regulation of Nrf2 and keap1 by the HO-system may constitute the basis of many physiological effects of HO-1 including its effects against oxidative stress and inflammation in a wide spectrum of cardiovascular, cardio-metabolic and other related diseases.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
