Abstract

Metastasis is a life-threatening feature of cancer and is primarily responsible for cancer patient mortality. Cross talk between tumor cells and endothelium is important for tumor progression and metastasis. However, very little is known about the mechanisms by which endothelial cells (ECs) that are close to tumor cells, respond to the tumor cells during tumor progression and metastasis. In this study, we exploited the use of EC-specific signal transducer activator of transcription 3 (STAT3) knockout mice to investigate the role of STAT3 in ECs in tumor progression and metastasis. We found that the loss of STAT3 in ECs did not affect primary Lewis lung carcinoma (LLC) tumor growth, but it reduced in vivo LLC metastasis in experimental and spontaneous metastasis models. Mechanistically, STAT3 activation upregulated cell adhesion molecule expression, including E-selectin and P-selectin, in murine endothelial MS-1 cells treated with tumor cell-conditioned media in vitro and in pre-metastatic lungs of tumor-bearing mice in vivo. We also found that both E-selectin and P-selectin were, at least in part, responsible for STAT3-induced adhesion and invasion of LLC cells through an EC monolayer. However, tumor cell-conditioned media from B16F10 melanoma cells did not activate STAT3 in MS-1 cells. As a result, EC STAT3 knockout did not affect B16F10 melanoma cell metastasis. In addition, various human cancer cells activated STAT3 in human ECs (HUVECs), resulting in increased cell adhesi…

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.
