Abstract

Pancreatic ductal adenocarcinoma (PDAC) develops a pronounced stromal response reflecting an aberrant wound-healing process. This stromal reaction features transdifferentiation of tissue-resident pancreatic stellate cells (PSC) into activated cancer-associated fibroblasts, a process induced by PDAC cells but of unclear significance for PDAC progression. Here, we show that PSCs undergo a dramatic lipid metabolic shift during differentiation in the context of pancreatic tumorigenesis, including remodeling of the intracellular lipidome and secretion of abundant lipids in the activated, fibroblastic state. Specifically, stroma-derived lysophosphatidylcholines support PDAC cell synthesis of phosphatidylcholines, key components of cell membranes, and also facilitate production of the potent wound-healing mediator lysophosphatidic acid (LPA) by the extracellular enzyme autotaxin, which is overexpressed in PDAC. The autotaxin–LPA axis promotes PDAC cell proliferation, migration, and AKT activation, and genetic or pharmacologic autotaxin inhibition suppresses PDAC growth in vivo. Our work demonstrates how PDAC cells exploit the local production of wound-healing mediators to stimulate their own growth and migration. Significance: Our work highlights an unanticipated role for PSCs in producing the oncogenic LPA signaling lipid and demonstrates how PDAC tumor cells co-opt the release of wound-healing mediators by neighboring PSCs to promote their own proliferation and migration.

  • Autophagy in stromal fibroblasts can generate alanine, which is subsequently used by PDAC cells to fuel the TCA cycle.

    “Autophagy in stromal fibroblasts can generate alanine, which is subsequently used by pancreatic ductal adenocarcinoma (PDAC) cells to fuel the tricarboxylic acid (TCA) cycle126,130,131.”

    From A framework for advancing our understanding of cancer-associated fibroblasts (2020) · cites this paper as [131]

    The Results (page not provided) state that autophagy-dependent alanine secretion by pancreatic stellate cells supports PDAC-cell mitochondrial metabolism. The paper does not specify that the alanine fuels the TCA cycle, so that more specific part of the claim is not supported by our copy. (LLM, conf=0.85)

  • Differential expression of solute carrier proteins can promote a one-way fibroblast-SLC1A4/PDAC-SLC38A2 exchange axis that enables alanine exchange.

    “Differential expression of solute carrier proteins (SLCs) can also function to promote a one-way fibroblast-SLC1A4 / PDAC-SLC38A2 exchange axis, enabling the exchange of alanine253.”

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.
