Here we developed massively parallel CRISPR¨CCpf1/Cas12a crRNA array profiling (MCAP), an approach for combinatorial interrogation of double knockouts in vivo. We designed an MCAP library of 11,934£¿arrays targeting 325£¿pairwise combinations of genes implicated in metastasis. By assessing the metastatic potential of the double knockouts in mice, we unveiled a quantitative landscape of genetic interactions that drive metastasis %U https://www.nature.com/articles/s41592-019-0371-5
