LDHA and pulmonary fibrosis: LDHA expression and LDH activity are increased in fibrotic murine lungs following bleomycin, and inhibition of pyruvate generation with a phosphofructokinase 3B inhibitor or broad‐spectrum LDH inhibition diminished lung fibrosis in that model (Judge et al., 2018; Kottmann et al., 2015; Xie et al., 2015).
