Abstract

DNA damage checkpoint genes, such as p53, are frequently mutated in human cancer, but the selective pressure for their inactivation remains elusive. We analysed a panel of human lung hyperplasias, all of which retained wild-type p53 genes and had no signs of gross chromosomal instability, and found signs of a DNA damage response, including histone H2AX and Chk2 phosphorylation, p53 accumulation, focal staining of p53 binding protein 1 (53BP1) and apoptosis. Progression to carcinoma was associated with p53 or 53BP1 inactivation and decreased apoptosis. A DNA damage response was also observed in dysplastic nevi and in human skin xenografts, in which hyperplasia was induced by overexpression of growth factors. Both lung and experimentally-induced skin hyperplasias showed allelic imbalance at loci that are prone to DNA double-strand break formation when DNA replication is compromised (common fragile sites). We propose that, from its earliest stages, cancer development is associated with DNA replication stress, which leads to DNA double-strand breaks, genomic instability and selective pressure for p53 mutations.

  • Human cells that bypass oncogene-induced senescence, as well as cells in some human premalignant lesions, show signs of a persistently activated DDR.

    “Moreover, human cells that bypass oncogene-induced senescence [ 58 ], as well as cells in some human premalignant lesions [ 73 , 74 ], show signs of a persistently activated DDR.”
  • Oncogene-induced senescence involves the DNA damage response.

    “OIS also involves the DNA damage response (2, 15, 28), but the mechanism of DNA damage and the contribution of mitochondria to it are unclear.”
  • DNA damage in the nucleus of normal cells expressing oncogenes has already been characterized and could arise by either replication stress or oxidative damage.

    “DNA damage in the nucleus of normal cell-expressing oncogenes already has been characterized using techniques that detect DNA breaks, and they could arise by either replication stress or oxidative damage (2, 15, 28).”
  • DDR activation and senescence, presumably owing to unscheduled DNA replication, are frequently observed in early stages of cancer lesions.

    “DDR activation and senescence, presumably owing to unscheduled DNA replication, are frequently observed in the early stages of cancer lesions, [69,70,356,357].”

    From Mechanisms and Regulation of Cellular Senescence (2021) · cites this paper as [357]

  • Activated DNA damage response markers occur in many pre-cancerous lesions, and checkpoint-compromising mutations are suggested to be required for tumor progression.

    “Indeed, the markers of activated DDR are found in many pre-cancerous lesions, and mutations compromising DNA damage checkpoint (for example, defects in ATM/p53 pathway) are suggested to be a prerequisite for tumor progression.13,14”

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.
