Loss of either β-arrestin1 or β-arrestin2 protects mice from bleomycin-induced mortality. (A) Survival curves for β-arrestin1−/−, β-arrestin2−/−, and WT mice after 2.5 U/kg bleomycin instillation. n = 10, *P < 0.05. (B) Lung sections from the surviving mice at Day 21 were stained with hematoxylin-eosin or Masson’s trichrome. Original magnification, 100×.
