Abstract

Most cases of breast cancer (BrCa) mortality are due to vascular metastasis. BrCa cells must intravasate through endothelial cells (ECs) to enter a blood vessel in the primary tumor and then adhere to ECs and extravasate at the metastatic site. In this study we demonstrate that inhibition of hypoxia-inducible factor (HIF) activity in BrCa cells by RNA interference or digoxin treatment inhibits primary tumor growth and also inhibits the metastasis of BrCa cells to the lungs by blocking the expression of angiopoietin-like 4 (ANGPTL4) and L1 cell adhesion molecule (L1CAM). ANGPTL4 is a secreted factor that inhibits EC-EC interaction, whereas L1CAM increases the adherence of BrCa cells to ECs. Interference with HIF, ANGPTL4 or L1CAM expression inhibits vascular metastasis of BrCa cells to the lungs.

  • HIF-1α-dependent expression of angiopoietin-like 4 and the L1 cell adhesion molecule further modulate intra- and extravasation.

    “HIF-1α-dependent expression of angiopoietin-like 4 and the L1 cell adhesion molecule further modulate intra-and extravasation (Zhang et al., 2012).”

    From Therapeutic targeting of hypoxia and hypoxia-inducible factors in cancer (2016) · cites this paper as Zhang et al., 2012

    The Results sections “ANGPTL4 promotes extravasation of BrCa cells in the lungs” and “L1CAM promotes extravasation” report that both factors promote extravasation; the Discussion describes their HIF-1-dependent expression. The paper mentions intravasation as a step in metastasis, but the passages do not show that ANGPTL4 or L1CAM modulates it. Page numbers were not provided. (LLM, conf=0.88)

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.
