Abstract

Cyclin-dependent kinases 4 and 6 (CDK4/6) are fundamental drivers of the cell cycle and are required for the initiation and progression of various malignancies. Pharmacological inhibitors of CDK4/6 have shown significant activity against several solid tumours. Their primary mechanism of action is thought to be the inhibition of phosphorylation of the retinoblastoma tumour suppressor, inducing G1 cell cycle arrest in tumour cells. Here we use mouse models of breast carcinoma and other solid tumours to show that selective CDK4/6 inhibitors not only induce tumour cell cycle arrest, but also promote anti-tumour immunity. We confirm this phenomenon through transcriptomic analysis of serial biopsies from a clinical trial of CDK4/6 inhibitor treatment for breast cancer. The enhanced anti-tumour immune response has two underpinnings. First, CDK4/6 inhibitors activate tumour cell expression of endogenous retroviral elements, thus increasing intracellular levels of double-stranded RNA. This in turn stimulates production of type III interferons and hence enhances tumour antigen presentation. Second, CDK4/6 inhibitors markedly suppress the proliferation of regulatory T cells. Mechanistically, the effects of CDK4/6 inhibitors both on tumour cells and on regulatory T cells are associated with reduced activity of the E2F target, DNA methyltransferase 1. Ultimately, these events promote cytotoxic T-cell-mediated clearance of tumour cells, which is further enhanced by the addition of immune checkpoint blockade. Our findings indicate that CDK4/6 inhibitors increase tumour immunogenicity and provide a rationale for new combination regimens comprising CDK4/6 inhibitors and immunotherapies as anti-cancer treatment.

  • In a mouse model of breast cancer, CDK4/6 inhibition-driven cellular senescence also triggered antitumour immunity, mediated by suppression of regulatory T cells and re-expression of endogenous retroviral elements, which elicited an interferon response.

    “Moreover, in a mouse model of breast cancer, CDK4/6 inhibition- driven cellular senescence also triggered antitumour immunity, mediated by suppression of regulatory Tcells and re- expression of endogenous retroviral elements, which elicited an interferon response 106,153 .”

  • CDK4/6 inhibitor-induced senescent non-malignant and malignant cells largely lack pro-inflammatory SASP factors.

    “CDK4/6 inhibitor- induced senescent non- malignant and malignant cells largely lack pro- inflammatory SASP factors 111,153 .”

    From Senescence and cancer — role and therapeutic opportunities (2022) · cites this paper as [153]

    The main text (indexed under Abstract; page unavailable) says abemaciclib induced senescence-like features in tumor cells without increasing key SASP factors, as detailed in Extended Data Figure 8. The paper does not establish the same finding for non-malignant cells, so that extension is unsupported by this source. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Despite the marked reduction in the inflammatory SASP response, CDK4/6 inhibition triggers antitumour immunity and favours senescent cell removal.

    “Importantly, despite the marked reduction in the inflammatory SASP response, CDK4/6 inhibition triggers antitumour immunity and favours senescent cell removal 111,153 .”

    From Senescence and cancer — role and therapeutic opportunities (2022) · cites this paper as [153]

    The paper reports that CDK4/6 inhibition promotes antitumour immunity and cytotoxic T-cell-mediated clearance of tumour cells (Abstract; page unavailable). It describes a senescence-like phenotype without increased expression of key SASP factors (main text and Extended Data Figure 8; pages unavailable), but does not establish a marked reduction in SASP or specifically show removal of senescent cells. (LLM, conf=0.86)

  • Targeted therapies such as EGFR inhibitors and CDK4/6 inhibitors can induce a strong reactivation of repeated elements in cancer cells, which results in cell death.

    “Interestingly, targeted therapies such as EGFR inhibitors and CDK4/6 inhibitors can induce a strong reactivation of repeated elements in cancer cells, which results in cell death [24,102].”
  • CDK4/CDK6 inhibitors stimulate immunity by promoting secretion of pro-inflammatory cytokines such as type III interferon and CCL5.

    “CDK4/CDK6 inhibitors mediate immunostimulatory effects by favoring the secretion of pro-inflammatory cytokines such as type III interferon (Goel et al., 2017) and CC-chemokine ligand 5 (CCL5) (Vilgelm et al., 2016).”

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.
