Values show limma-voom log 2 fold changes between 24 and 0 h of treatment for each NRF2 construct, normalized by subtracting the log 2 fold change between 24 and 0 h of Luciferase. Highlighted points are NRF2 signature genes colored by cosine similarity between WT and Neh4/5mut. Cosine values of 1 represent the same angle and hence no differential expression between Neh4/5mut and WT NRF2, with more divergence as values decrease.

Correlations among redox status (dose and time dependent) and cardiac functional outcomes (systolic and diastolic) are demonstrated in both young (2, 3, and 6 months) and old (15 months) TGL, TGH, and DTG mice, indicating remarkable impacts of cRS on both (A) systolic (i.e., EF%) and (B) diastolic (i.e., M/V E/A ratio) functions. (C) The diastolic function was deteriorating to increase reductive potential, whereas systolic function was elevated, suggesting that (D) varying degrees of reductive-redox through dose- and time-dependent Nrf2 expression influence on the structural and functional phenotypes of heart. (E) A schematic overview of how the caNrf2 expression induces cRS and depletes biological ROS signals, as well as how cRS (>6 months) induces the cardiac structural and functional remodeling by promoting cardiac hypertrophy and diastolic dysfunction. Doubling the myocardial Nrf2 levels (in DTG) further advances RS and accelerates cardiac remodeling/diastolic dysfunction as early as 1.8 months of age. Pharmacologic depletion of glutathione using BSO abolishes RS-mediated myocardial remodeling. cRS, chronic reductive stress; ROS, reactive oxygen species. Color images are available online.
