Abstract

Cancer cells acquire distinct metabolic adaptations to survive stress associated with tumour growth and to satisfy the anabolic demands of proliferation. The tumour suppressor protein p53 (also known as TP53) influences a range of cellular metabolic processes, including glycolysis, oxidative phosphorylation, glutaminolysis and anti-oxidant response. In contrast to its role in promoting apoptosis during DNA-damaging stress, p53 can promote cell survival during metabolic stress, a function that may contribute not only to tumour suppression but also to non-cancer-associated functions of p53. Here we show that human cancer cells rapidly use exogenous serine and that serine deprivation triggered activation of the serine synthesis pathway and rapidly suppressed aerobic glycolysis, resulting in an increased flux to the tricarboxylic acid cycle. Transient p53-p21 (also known as CDKN1A) activation and cell-cycle arrest promoted cell survival by efficiently channelling depleted serine stores to glutathione synthesis, thus preserving cellular anti-oxidant capacity. Cells lacking p53 failed to complete the response to serine depletion, resulting in oxidative stress, reduced viability and severely impaired proliferation. The role of p53 in supporting cancer cell proliferation under serine starvation was translated to an in vivo model, indicating that serine depletion has a potential role in the treatment of p53-deficient tumours.

  • Certain tumors are dependent on uptake of environmental serine.

    “Certain tumors are dependent on uptake of environmental serine (Jain et al., 2012; Maddocks et al., 2013; Maddocks et al., 2017), and limiting plasma serine availability can be beneficial for patients with these cancers.”

  • Serine deprivation by dietary restriction is sufficient to slow growth of both xenograft and autochthonous cancer models, although efficacy is influenced by the oncogenic driver mutation and tissue context.

    “Additionally, serine deprivation by dietary restriction is sufficient to slow growth of both xenograft (Gravel et al., 2014; Maddocks et al., 2013) and autochthonous cancer models, although efficacy of serine deprivation appears to be influenced by both the oncogenic driver mutation and tissue context (Maddocks et al., 2017).”

  • Combining serine restriction with other drugs may potentiate antitumor responses.

    “Combining serine restriction with other drugs may also potentiate antitumor responses (Gravel et al., 2014; Maddocks et al., 2013; Maddocks et al., 2017).”

    From Targeting Metabolism for Cancer Therapy (2017) · cites this paper as Maddocks et al., 2013

  • Serine production is of particular significance because serine is a major substrate for the folate/one-carbon cycle whose metabolites contribute to various cellular biosynthetic and regulatory processes.

    “Of particular significance is serine production because it is a major substrate for the folate/one-carbon cycle whose metabolites contribute to various cellular biosynthetic and regulatory processes (212, 213).”
  • In mice, colon cancer xenografts grow less when serine and glycine are absent from the diet.

    “Indeed, dietary serine and glycine deficiency has been shown to impair xenograft growth of colon cancer cells in mice (Maddocks et al., 2013).”

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.
