(A) Schematic diagram of experimental design (n = 3). (B) PL mice were injected once with 45 mg/kg of TAM. Cell proliferation, apoptosis, and ADM were analyzed on Day 4, Day 8, and Day 12 by co-staining anti-YFP with anti-Ki67, anti-cleaved-caspase-3, anti-amylase, and anti-CK19 antibodies. Nuclei stained with DAPI (Blue). Percentages of Ki67, cleaved caspase-3 (n = 3), and YFP (n = 4) cells were quantified by IHC profiler score. Underlying numerical values can be found in S1 Data. (C) YAP1 and TAZ were detected by IHC in PL mice after injection with 45 mg/kg of TAM. ADM, acinar-to-ductal metaplasia; CK19, cytokeratin 19; IHC, immunohistochemistry; Ki67, antigen identified by monoclonal antibody Ki 67; LATS1, large tumor suppressor 1; P, control; PL, double knockout; TAM, tamoxifen; TAZ, transcriptional coactivator with PDZ binding motif; YAP1, yes-associated protein 1; YFP, yellow fluorescent protein.
