Abstract

Inflammatory mechanisms influence tumorigenesis and metastatic progression even in cancers whose aetiology does not involve pre-existing inflammation or infection, such as breast and prostate cancers. For instance, prostate cancer metastasis is associated with the infiltration of lymphocytes into advanced tumours and the upregulation of two tumour-necrosis-factor family members: receptor activator of nuclear factor-κB (RANK) ligand (RANKL) and lymphotoxin. But the source of RANKL and its role in metastasis have not been established. RANKL and its receptor RANK control the proliferation of mammary lobuloalveolar cells during pregnancy through inhibitor of nuclear factor-κB (IκB) kinase-α (IKK-α), a protein kinase that is needed for the self-renewal of mammary cancer progenitors and for prostate cancer metastasis. We therefore examined whether RANKL, RANK and IKK-α are also involved in mammary/breast cancer metastasis. Indeed, RANK signalling in mammary carcinoma cells that overexpress the proto-oncogene Erbb2 (also known as Neu), which is frequently amplified in metastatic human breast cancers, was important for pulmonary metastasis. Metastatic spread of Erbb2-transformed carcinoma cells also required CD4+CD25+ T cells, whose major pro-metastatic function was RANKL production. Most RANKL-producing T cells expressed forkhead box P3 (FOXP3), a transcription factor produced by regulatory T cells, and were located next to smooth muscle actin (SMA)+ stromal cells in mouse and human breast cancers. The dependence of pulmonary metastasis on T cells was replaceable by exogenous RANKL, which also stimulated pulmonary metastasis of RANK+ human breast cancer cells. These results are consistent with the adverse impact of tumour-infiltrating CD4+ or FOXP3+ T cells on human breast cancer prognosis and suggest that the targeting of RANKL–RANK can be used in conjunction with the therapeutic elimination of primary breast tumours to prevent recurrent metastatic disease.

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.
