Abstract

Cyclin dependent kinase 4/6 (CDK4/6) inhibitors (CDK4/6i) are effective in breast cancer; however, drug resistance is frequently encountered and poorly understood. We conducted a genomic analysis of 348 estrogen receptor-positive (ER+) breast cancers treated with CDK4/6i and identified loss-of-function mutations affecting FAT1 and RB1 linked to drug resistance. FAT1 loss led to marked elevations in CDK6, the suppression of which restored sensitivity to CDK4/6i. The induction of CDK6 was mediated by the Hippo pathway with accumulation of YAP and TAZ transcription factors on the CDK6 promoter. Genomic alterations in other Hippo pathway components were also found to promote CDK4/6i resistance. These findings uncover a tumor suppressor function of Hippo signaling in ER+ breast cancer and establish FAT1 loss as a mechanism of resistance to CDK4/6i.

  • Dysregulation of the Hippo-YAP/TAZ pathway is a central resistance mechanism in various tumors to multiple targeted therapies, chemotherapies, hormonal therapies, and immunotherapies.

    “Emerging evidence suggests that dysregulation of the Hippo-YAP/TAZ pathway is a central resistance mechanism in various tumors to multiple targeted therapies, chemotherapies, hormonal therapies, and immunotherapies (23–27).”

    From YAP/TAZ mediates resistance to KRAS inhibitors through inhibiting proapoptosis and activating the SLC7A5/mTOR axis (2024) · cites this paper as [25]

    The Results section ('FAT1 regulates CDK6 via the Hippo pathway'; page unavailable) reports that suppressing YAP/TAZ restored sensitivity to CDK4/6 inhibitors in FAT1-loss breast cancer cells. This supports resistance to a targeted therapy in that setting, but the paper does not establish Hippo-YAP/TAZ dysregulation as a central resistance mechanism across various tumors or against chemotherapies, hormonal therapies, and immunotherapies.

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.
