Abstract

It has been increasingly recognized lately that aberrant cellular metabolism plays an important role in the pathogenesis of pulmonary fibrosis. In our previous systemic studies, we found that human lung myofibroblasts undergo glutaminolytic reprogramming, which is mediated by an increased expression of glutaminase (Gls) 1. We showed that augmented glutaminolysis critically regulates collagen production by promoting its stabilization in human lung myofibroblasts. Our study indicates that lung fibroblast Gls1 is a promising therapeutic target for this disease. In this investigation, we primarily focused on delineating the in vivo role of fibroblast Gls1 in mouse models of pulmonary fibrosis and determining the efficacy of Gls1 inhibition in treating this pathology. We now show that fibroblast Gls1 is upregulated in fibrotic mouse lungs. We present evidence that mice with ablation of fibroblast Gls1 are protected from bleomycin-induced lung fibrosis. We show that the Gls1 inhibitor, CB-839, is therapeutically efficacious in treating both bleomycin- and transforming growth factor-β1–induced pulmonary fibrosis. Our study has thus established a solid rationale for advancing Gls1 inhibitors, particularly CB-839, to the next stage of testing in the treatment of this disease.

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.
