Abstract

Reprogrammed glucose metabolism as a result of increased glycolysis and glucose uptake is a hallmark of cancer. Here we show that cancer cells can suppress glucose uptake by non-tumour cells in the premetastatic niche, by secreting vesicles that carry high levels of the miR-122 microRNA. High miR-122 levels in the circulation have been associated with metastasis in breast cancer patients, and we show that cancer-cell-secreted miR-122 facilitates metastasis by increasing nutrient availability in the premetastatic niche. Mechanistically, cancer-cell-derived miR-122 suppresses glucose uptake by niche cells in vitro and in vivo by downregulating the glycolytic enzyme pyruvate kinase. In vivo inhibition of miR-122 restores glucose uptake in distant organs, including brain and lungs, and decreases the incidence of metastasis. These results demonstrate that, by modifying glucose utilization by recipient premetastatic niche cells, cancer-derived extracellular miR-122 is able to reprogram systemic energy metabolism to facilitate disease progression.

  • miR-122 downregulates the glycolytic enzyme pyruvate kinase and restores glucose uptake by lungs and brain and lessens disease progression.

    “Mechanistically, miR-122 downregulate the glycolytic enzyme pyruvate kinase and restores glucose uptake by lungs and brain and lessen disease progression [177].”

    From Tumor microenvironment complexity and therapeutic implications at a glance (2020) · cites this paper as [177]

    The Results section confirms that miR-122 downregulates pyruvate kinase, but reports that miR-122 reduces glucose uptake by niche cells and promotes metastasis—the opposite of the claimed effects. In “Systemic miR-122 intervention,” inhibiting miR-122 reduced the incidence of brain and lung metastasis and alleviated suppressed glucose uptake in the brain; restoration of uptake in the lungs was not significant. (LLM, conf=0.91)

    Checked by a reasoning model — may be wrong.

  • Cancer cells can systemically reprogram energy metabolism by recipient premetastatic niche cells to promote metastasis.

    “Another interesting role of the exosome as mediators of cancer cell interaction with non-malignant cells is the observation that cancer cells can systemically reprogram energy metabolism by recipient premetastatic niche cells to promote metastasis.”

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.
