Abstract

Aberrant expression of vascular cell adhesion molecule-1 (VCAM-1) in breast cancer cells is associated with lung relapse, but the role of VCAM-1 as a mediator of metastasis has remained unknown. We report that VCAM-1 provides a survival advantage to breast cancer cells that infiltrate leukocyte-rich microenvironments such as the lungs. VCAM-1 tethers metastasis-associated macrophages to cancer cells via counter-receptor α4-integrins. Clustering of cell surface VCAM-1, acting through Ezrin, triggers Akt activation and protects cancer cells from proapoptotic cytokines such as TRAIL. This prosurvival function of VCAM-1 can be blocked by antibodies against α4-integrins. Thus, newly disseminated cancer cells expressing VCAM-1 can thrive in leukocyte-rich microenvironments through juxtacrine activation of a VCAM-1-Ezrin-PI3K/Akt survival pathway.

  • The role of immune cells in cancer progression, such as macrophages, may differ between organs.

    “We propose that cancer-immune cell interactions should be studied in organ-specific microfluidic models, since recent studies suggest that the role of immune cells in cancer progression, such as macrophages, may differ between organs[87].”

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.
