Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Immunotherapy with PD-1 checkpoint blockade is effective in only a minority of patients with cancer, suggesting that additional treatment strategies are needed. Here we use a pooled in vivo genetic screening approach using CRISPR-Cas9 genome editing in transplantable tumours in mice treated with immunotherapy to discover previously undescribed immunotherapy targets. We tested 2,368 genes expressed by melanoma cells to identify ... [more]

Throughput

  • Low Throughput

Ontology Terms

  • phenotype: altered tumor susceptibility (MP:0002166)

Additional Notes

  • the mechanism by which Ptpn2 deficiency sensitizes tumour cells to immunotherapy is dependent on the sensing of IFNgamma and is abrogated by deletion of Stat1, Jak1 or Ifngr1
