Abstract

Tumors are largely classified by histologic appearance, yet morphologic features do not necessarily predict cellular origin. To determine the origin of pancreatic ductal adenocarcinoma (PDA), we labeled and traced pancreatic cell populations after induction of a PDA-initiating Kras mutation. Our studies reveal that ductal and stem-like centroacinar cells are surprisingly refractory to oncogenic transformation, whereas acinar cells readily form PDA precursor lesions with ductal features. We show that formation of acinar-derived premalignant lesions depends on ectopic induction of the ductal gene Sox9. Moreover, when concomitantly expressed with oncogenic Kras, Sox9 accelerates formation of premalignant lesions. These results provide insight into the cellular origin of PDA and suggest that its precursors arise via induction of a duct-like state in acinar cells.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cerulein-induced pancreatitis, which damages acinar cells, did not promote KRAS-mediated ductal-lineage tumorigenesis.

    “This was not observed in the context of damage through cerulein-induced pancreatitis118, which drives inflammation through damage of acinar cells.”

  • Deletion of Sox9 prevented KRAS-driven transformation, while Sox9 overexpression accelerated PanIN development.

    “Deletion of the ductal progenitor gene Sox9 prevented KRAS-driven transformation, while Sox9 overexpression accelerated PanIN development.”

  • In a direct comparison, oncogenic KRAS promoted adult acinar cells to generate neoplastic lesions at a frequency over 100-fold higher than ductal cells.

    “The first direct comparison using adult acinar vs. ductal expression of oncogenic KRAS demonstrated that KRAS promotes acinar cells to generate neoplastic lesions at a frequency over a hundred-fold higher than ductal cells118.”

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.
