To examine the relative contribution of TBX3 and NFIC to cell viability, we analyzed genome-scale RNAi screens performed in eight prostate cancer cell lines as a part of Project Achilles 2.20.1 (Cowley et al., 2014; Shalem et al., 2014; Tsherniak et al., 2017). This evidence concerns the gene NFIC and prostate carcinoma.
