N1 - Funding Information:
The work done in the laboratory of E.G. was supported by La Ligue Nationale Contre Le Cancer (Équipe Labellisée), Institut National du Cancer (TELOFUN and TELOCHROM programme), ANR (INNATELO programme) and the European Union (FP7-Telomarker, Health-F2-2007-200950). The E.V. laboratory is supported by ANR (programme INNATELO) and the European Union (ERC advanced grant THINK). We thank L. Zitvogel (Institut Gustave Roussy, France) for providing the XMG1.2 clone, R. Weinberg (Whitehead Institute for Biomedical Research, Cambridge, Massachusetts, USA) for providing the BJ-HELT cells, C. Delprat (University of Lyon, France) for Luminex analyses, J. Lingner (Ecole Polytechnique Fdrale de Lausanne, Switzerland) for providing the ATR shRNA and ATM shRNA plasmids, and V. Leopold (IRCAN, France) for providing the subcloning vectors. We are also grateful to C. D’Angelo and M. Scarsella for technical support. This work was performed using the microscopy (PICMI), cytometry (CYTOMED) and animal house facilities of IRCAN. The work done by the A.B. group was supported by grants from the Italian Association for Cancer Research (#11567 and #9979). A.B. was supported by the Short-Term Fellowship Programme of the EMBO. M.J.S. was supported by a National Health and Medical Research Council Australia Fellowship. J.C-V. was supported by a postdoctoral fellowship from La Ligue Nationale Contre Le Cancer.

N2 - Dysfunctional telomeres suppress tumour progression by activating cell-intrinsic programs that lead to growth arrest. Increased levels of TRF2, a key factor in telomere protection, are observed in various human malignancies and contribute to oncogenesis. We demonstrate here that a high level of TRF2 in tumour cells decreased their ability to recruit and activate natural killer (NK) cells. Conversely, a reduced dose of TRF2 enabled tumour cells to be more easily eliminated by NK cells. Consistent with these results, a progressive upregulation of TRF2 correlated with decreased NK cell density during the early development of human colon cancer. By screening for TRF2-bound genes, we found that HS3ST4 - A gene encoding for the heparan sulphate (glucosamine) 3-O-sulphotransferase 4 - was regulated by TRF2 and inhibited the recruitment of NK cells in an epistatic relationship with TRF2. Overall, these results reveal a TRF2-dependent pathway that is tumour-cell extrinsic and regulates NK cell immunity.
