Abstract

Liver cancer remains difficult to treat, owing to a paucity of drugs that target critical dependencies 1,2; broad-spectrum kinase inhibitors such as sorafenib provide only a modest benefit to patients with hepatocellular carcinoma 3. The induction of senescence may represent a strategy for the treatment of cancer, especially when combined with a second drug that selectively eliminates senescent cancer cells (senolysis)4,5. Here, using a kinome-focused genetic screen, we show that pharmacological inhibition of the DNA-replication kinase CDC7 induces senescence selectively in liver cancer cells with mutations in TP53. A follow-up chemical screen identified the antidepressant sertraline as an agent that kills hepatocellular carcinoma cells that have been rendered senescent by inhibition of CDC7. Sertraline suppressed mTOR signalling, and selective drugs that target this pathway were highly effective in causing the apoptotic cell death of hepatocellular carcinoma cells treated with a CDC7 inhibitor. The feedback reactivation of mTOR signalling after its inhibition 6 is blocked in cells that have been treated with a CDC7 inhibitor, which leads to the sustained inhibition of mTOR and cell death. Using multiple in vivo mouse models of liver cancer, we show that treatment with combined inhibition of of CDC7 and mTOR results in a marked reduction of tumour growth. Our data indicate that exploiting an induced vulnerability could be an effective treatment for liver cancer.

  • Senescence induction by inhibition of DNA replication kinase CDC7 paired with a senolytic that disrupts mTOR signaling induces apoptosis in senescent human liver cancer cells and improves survival in mouse models of HCC.

    “Senescence induction by inhibition of DNA replication kinase CDC7 has also been paired with a senolytic that disrupts mTOR signaling, inducing apoptosis in senescent human liver cancer cells and improving survival in mouse models of HCC (Wang et al. 2019).”

    From Senescence and the SASP: many therapeutic avenues (2020) · cites this paper as Wang et al. 2019

    The Abstract reports that CDC7 inhibition induced senescence selectively in TP53-mutant liver cancer cells and that mTOR inhibition caused apoptosis in CDC7-inhibitor-treated HCC cells. It also reports increased survival with the combination in one specific mouse model, MycOE;Trp53KO HCC; the claim’s plural “mouse models” overstates the survival finding. The paper reports tumour-growth inhibition in its other in vivo models. (LLM, conf=0.84)

  • Many of the genes in CisSig have been denoted as possible therapeutic targets in a variety of epithelial-based cancers.

    “Furthermore, many of the genes have been denoted as possible therapeutic targets in a variety of epithelial-based cancers, such as CDC7 in oral squamous carcinoma30 and liver cancer31, ATP1B3 in gastric cancer32, and FKBP14 in ovarian cancer33.”
  • In a mouse model of liver cancer, the mTOR inhibitor AZD8055 showed senolytic potential against cancer cells with senescence induced by small-molecule inhibitors of CDC7.

    “In a mouse model of liver cancer, the mTOR inhibitor AZD8055 also showed senolytic potential against cancer cells with senescence induced by small- molecule inhibitors of CDC7 (ref. 207 ) .”

  • Elevated expression of p16 in melanocytes and epidermal and dermal cells is associated with human aging.

    “Elevated expression of p16 in melanocytes156 and epidermal and dermal cells157,158 is associated with human aging.”

    From Guidelines for minimal information on cellular senescence experimentation in vivo (2024) · cites this paper as [156]

    The paper’s Abstract discusses p16INK4A-positive cells in treated mouse liver tumors, not p16 expression in human skin during aging. Searches for melanocytes, epidermal and dermal cells, and skin aging found no passage addressing the attributed association. (LLM, conf=0.78)

  • Approaches based on inducing senescence in a large fraction of tumors have the potential to enter clinical practice, especially when combined with adjuvant immunotherapy or senolytic therapy to remove harmful senescent escaper variants.

    “Based on the preclinical experimental evidence enumerated here, approaches based on the induction of senescence in large fraction of tumors have the potential to enter the realm of the clinical practice, even more if combined with adjuvant immunotherapy or senolytic therapy to remove potentially harmful senescent escaper variants, as recently proposed.189,202,203”

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.
