Abstract

Metastasis to distant tissues is the chief driver of breast cancer–related mortality, but little is known about the systemic physiologic dynamics that regulate this process. To investigate the role of neuroendocrine activation in cancer progression, we used in vivo bioluminescence imaging to track the development of metastasis in an orthotopic mouse model of breast cancer. Stress-induced neuroendocrine activation had a negligible effect on growth of the primary tumor but induced a 30-fold increase in metastasis to distant tissues including the lymph nodes and lung. These effects were mediated by β-adrenergic signaling, which increased the infiltration of CD11b+F4/80+ macrophages into primary tumor parenchyma and thereby induced a prometastatic gene expression signature accompanied by indications of M2 macrophage differentiation. Pharmacologic activation of β-adrenergic signaling induced similar effects, and treatment of stressed animals with the β-antagonist propranolol reversed the stress-induced macrophage infiltration and inhibited tumor spread to distant tissues. The effects of stress on distant metastasis were also inhibited by in vivo macrophage suppression using the CSF-1 receptor kinase inhibitor GW2580. These findings identify activation of the sympathetic nervous system as a novel neural regulator of breast cancer metastasis and suggest new strategies for antimetastatic therapies that target the β-adrenergic induction of prometastatic gene expression in primary breast cancers.

  • Sloan et al. found that stress-induced and pharmacological β-adrenergic stimulation promoted macrophage migration into tumor tissue in a mouse model of breast cancer; these macrophages adopted an immunosuppressive M2 phenotype, leading to increased production of TGF-β, VEGF, and MMP-9, which promoted angiogenesis and metastasis.

    “Furthermore, Sloan et al. found that both stress-induced and pharmacological β-adrenergic stimulation promoted macrophage migration into tumor tissue in a mouse model of breast cancer. These macrophages then adopted an immunosuppressive M2 phenotype, leading to increased production of TGF-β, VEGF, and MMP-9, which in turn promoted angiogenesis and metastasis.322”

  • Findings from animal and in vitro studies back up the human data on psychosocial factors and tumor progression.

    “Parallel findings in animal and in vitro models support these data [11, 16–22].”
  • In metastatic breast cancer, stress effects on tumor metastasis are mediated by beta-adrenergic up-regulation of monocytes and macrophages within the tumor microenvironment.

    “In the context of metastatic breast cancer, for example, stress effects on tumor metastasis are mediated by β-adrenergic up-regulation of monocytes and macrophages within the tumor microenvironment [44] (i.e., the same dynamic that drives the CTRA transcriptome shift in circulating blood [9]).”

  • Parallel effects have been observed in experimental animal models of cancer, and those analyses identify a prominent role for SNS activation of beta-adrenergic signaling.

    “Parallel effects have been observed in experimental animal models of cancer, and those analyses again identify a prominent role for SNS activation of β-adrenergic signaling [43], [44].”

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.
