摘要

Oncogenic mutations are widespread in normal human tissues(1). Similarly, in murine chimeras, cells carrying an oncogenic lesion contribute normal cells to adult tissues without causing cancer(2,3,4). How lineages that escape cancer via normal development differ from the minority that succumb is unclear. Tumours exhibit characteristic cancer hallmarks; we therefore searched for hallmarks that differentiate cancer-prone lineages from resistant lineages. Here we show that total cell cycle duration (T-c) predicts transformation susceptibility across multiple tumour types. Cancer-prone Rb- and p107-deficient retina (Rb is also known as Rb1 and p107 is also known as Rbl1) exhibited defects in apoptosis, senescence, immune surveillance, angiogenesis, DNA repair, polarity and proliferation. Perturbing the SKP2-p27-CDK2/CDK1 axis could block cancer without affecting these hallmarks. Thus, cancer requires more than the presence of its hallmarks. Notably, every tumour-suppressive mutation that we tested increased T-c, and the T-c of the cell of origin of retinoblastoma cells was half that of resistant lineages. T-c also differentiated the cell of origin in Rb-/- pituitary cancer. In lung, loss of Rb and p53 (also known as Trp53) transforms neuroendocrine cells, whereas Kras(G12D) or Braf(V600E) mutations transform alveolar type 2 cells(5,6,7). The shortest T-c consistently identified the cell of origin, regardless of mutation timing. Thus, relative T-c is a hallmark of initiation that distinguishes cancer-prone from cancer-resistant lineages in several settings, explaining how mutated cells escape transformation without inducing apoptosis, senescence or immune surveillance.
