Abstract

Significance: The recruitment of host stromal cells, such as macrophages and mesenchymal stem cells (MSCs), to the primary tumor is a critical step toward cancer malignancy. We have identified signals that are exchanged between breast cancer cells (BCCs) and MSCs. This signaling increases the recruitment of both MSCs and macrophages to primary tumors and increases metastasis of BCCs to lymph nodes and lungs. Reduced oxygen levels (hypoxia) in breast cancers are associated with increased risk of metastasis and decreased patient survival. We show that hypoxia stimulates signaling between BCCs and MSCs due to the activity of hypoxia-inducible factors (HIFs). Drugs that block HIF activity prevent signaling and macrophage recruitment, which suggests that they may be useful additions to breast cancer therapy.

  • HIF-1α or HIF-2α expression in TAMs is associated with tumor progression and/or poor prognosis in multiple tumor types.

    “Both HIF-1α or HIF-2α expression in TAMs have been associated with tumor progression and/or poor prognosis in multiple tumor types, whereas lack of HIF-1α or HIF-2α in TAMs decreases metastasis, cell proliferation, and expression of pro-inflammatory cytokines such as IL-6 [73–76].”

    From The HIF Axes in Cancer - Angiogenesis, Metabolism and Immune-Modulation (2025) · cites this paper as [75]

    The section ‘HIF-Dependent BCC-MSC Interactions Promote TAM and Myeloid-’ reports that hypoxia induces HIF-1α and HIF-2α in macrophages, activating genes with prometastatic functions. The introduction also links TAM density—not HIF expression in TAMs—to metastasis and mortality in breast cancer. The paper does not establish the claimed association between HIF expression in TAMs and poor prognosis across multiple tumor types; its HIF-knockdown experiments target breast cancer cells, not TAMs. (LLM, conf=0.84)

    In the section on the syngeneic mouse mammary carcinoma model (page not available), HIF knockdown in breast cancer cells reduced metastasis; HIF-1α knockdown also reduced primary tumor growth. The knockdown was not in TAMs, and the cited passages do not establish reduced cell proliferation or IL-6 expression. (LLM, conf=0.87)

  • Hypoxia is a hallmark of most solid tumors and a common trait of the tumor microenvironment associated with cancer progression and metastasis.

    “Hypoxia is a hallmark of most solid tumors and a common trait of TME that is associated with cancer progression and metastasis8–10.”
  • Hypoxia plays a crucial role in tumor growth, metastasis, and drug resistance in solid tumors.

    “Hypoxia plays a crucial role in tumor growth, metastasis, and drug resistance in solid tumors8,9”
  • Hypoxic signaling in MDSCs and macrophages directly contributes to tumor progression by promoting an immunosuppressive phenotype and stimulating angiogenesis.

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.
