Abstract

Intra-abdominal tumors, such as ovarian cancer, have a clear predilection for metastasis to the omentum, an organ primarily composed of adipocytes. Currently, it is unclear why tumor cells preferentially home to and proliferate in the omentum, yet omental metastases typically represent the largest tumor in the abdominal cavities of women with ovarian cancer. We show here that primary human omental adipocytes promote homing, migration and invasion of ovarian cancer cells, and that adipokines including interleukin-8 (IL-8) mediate these activities. Adipocyte-ovarian cancer cell coculture led to the direct transfer of lipids from adipocytes to ovarian cancer cells and promoted in vitro and in vivo tumor growth. Furthermore, coculture induced lipolysis in adipocytes and β-oxidation in cancer cells, suggesting adipocytes act as an energy source for the cancer cells. A protein array identified upregulation of fatty acid-binding protein 4 (FABP4, also known as aP2) in omental metastases as compared to primary ovarian tumors, and FABP4 expression was detected in ovarian cancer cells at the adipocyte-tumor cell interface. FABP4 deficiency substantially impaired metastatic tumor growth in mice, indicating that FABP4 has a key role in ovarian cancer metastasis. These data indicate adipocytes provide fatty acids for rapid tumor growth, identifying lipid metabolism and transport as new targets for the treatment of cancers where adipocytes are a major component of the microenvironment.

  • Adipocytes constitute a significant stromal component in the tumor microenvironment of several malignancies, including breast, ovarian, and colorectal cancers.

    “Adipocytes constitute a significant stromal component in the TME of several malignancies, including breast, ovarian, and colorectal cancers [57,58].”

    From Modeling Tumor Microenvironment Complexity In Vitro: Spheroids as Physiologically Relevant Tumor Models and Strategies for Their Analysis (2025) · cites this paper as [57]

    The supplied passages describe adipocytes in the ovarian cancer metastatic microenvironment and identify breast tissue as an adipocyte-rich environment. They also report coculturing colon cancer cells with adipocytes, but do not establish that adipocytes are a significant stromal component of colorectal tumors. The claim extends beyond what this paper shows for colorectal cancer. (LLM, conf=0.85)

  • Upregulation of FABP4 on metastatic ovarian cancer cells allows acquisition of fatty acids from omental adipocytes.

    “upregulation of a long chain fatty acid-binding protein FABP4 on the surface of metastatic ovarian cancer cells allows them to acquire fatty acids directly from the adipocytes of the omental fat”

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.
