The transcription factor NRF2 protects against pulmonary fibrosis
Abstract
The molecular mechanisms of pulmonary fibrosis are poorly understood, although reactive oxygen species are thought to have an important role. NRF2 is a transcription factor that protects cells and tissues from oxidative stress by activating protective antioxidant and detoxifying enzymes. We hypothesized that NRF2 protects lungs from injury and fibrosis induced by bleomycin, an anti‐neoplastic agent that causes pulmonary fibrosis in susceptible patients. To test this hypothesis, mice with targeted deletion of Nrf2 ( Nrf2 ‒/‒ ) and wild‐type ( Nrf2 +/+ ) mice were treated with bleomycin or vehicle, and pulmonary injury and fibrotic responses were compared. Bleomycin‐induced increases in lung weight, epithelial cell death, and inflammation were significantly greater in Nrf2 ‒/‒ mice than in Nrf2 +/+ mice. Indices of lung fibrosis (hydroxyproline content, collagen accumulation, fibrotic score, cell proliferation) were significantly greater in bleomycin‐treated Nrf2 ‒/‒ mice, compared with Nrf2 +/+ mice. NRF2 expression and activity were elevated in Nrf2 +/+ mice by bleomycin. Bleomycin caused greater up‐regulation of several NRF2‐inducible antioxidant enzyme genes and protein products in Nrf2 +/+ mice compared with Nrf2 ‒/‒ mice. Further, bleomycin‐induced transcripts and protein levels of lung injury and fibrosis markers were significantly attenuated in Nrf2 +/+ mice compared with Nrf2 ‒/‒ mice. Results demonstrated that NRF2 has a critical role in protection against pulmonary fibrosis, presumably through enhancement of cellular antioxidant capacity. This study has important implications for the development of intervention strategies against fibrosis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
