Abstract

Fatty acid synthase (FASN) and ATP-citrate lyase, key enzymes of de novo lipogenesis, are significantly upregulated and activated in many cancers and portend poor prognosis. Even though the role of lipogenesis in providing proliferative and survival advantages to cancer cells has been described, the impact of aberrant activation of lipogenic enzymes on cancer progression remains unknown. In this study, we found that elevated expression of FASN is associated with advanced stages of colorectal cancer (CRC) and liver metastasis, suggesting that it may play a role in progression of CRC to metastatic disease. Targeted inhibition of lipogenic enzymes abolished expression of CD44, a transmembrane protein associated with metastases in several cancers including CRC. In addition, inhibition of lipogenic enzymes and reduced expression of CD44 attenuated the activation of MET, Akt, FAK, and paxillin, which are known to regulate adhesion, migration, and invasion. These changes were consistent with an observed decrease in migration and adhesion of CRC cells in functional assays and with reorganization of actin cytoskeleton upon FASN inhibition. Despite the modest effect of FASN inhibition on tumor growth in xenografts, attenuation of lipogenesis completely abolished establishment of hepatic metastasis and formation of secondary metastasis. Together, our findings suggest that targeting de novo lipogenesis may be a potential treatment strategy for advanced CRC.

  • Overexpression of FASN promotes CRC growth and metastasis via multiple mechanisms including upregulation of Cyclin D1 and VEGF secretion.

    “We have previously reported that overexpression of FASN promotes CRC growth and metastasis via multiple mechanisms including upregulation of Cyclin D1 and VEGF secretion [10,29,47,49].”

    From Inhibition of fatty acid synthase enhances therapeutic efficacy and delays acquired resistance to BRAF-targeted therapy in colorectal cancer (2026) · cites this paper as [29]

    The Results section ('Expression of FASN regulates CRC cell growth, adhesion, and migration'; page unavailable) reports that FASN knockdown reduced colony formation, adhesion, and migration. The Abstract (page unavailable) reports that inhibiting lipogenesis abolished hepatic metastasis in xenografts. These findings support a role for FASN in CRC growth and metastasis, but our copy does not support the specified mechanisms of Cyclin D1 upregulation or VEGF secretion; searches for both terms found no relevant passage.

  • FASN is highly expressed in colorectal cancer.

    “We and others have previously reported that FASN is highly expressed in CRC [29,30].”

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.
