However, inspection of periodic acid–Schiff (PAS)–stained pancreatic sections revealed that like Cby1-KO mice (Cyge et al, 2021), ciBAR1-KO mice consistently show common features of acinar cell degeneration such as disorganized acini, lipomatosis (Fig 2C, dotted line), abundant ducts (Fig 2C, arrowheads), fibrosis (Fig 2D, arrowheads), and infiltration of inflammatory cells (Fig 2E). The gene discussed is CBY1; the disease is lipomatosis.
