We assessed tumor-bearing RictorFL/FLNIC mice at 28 days after initial tumor palpation (Fig. 1a), and found that only 55% (5/9) of tumor-bearing RictorFL/FLNIC mice harbored lung metastases (Fig. 1b, left panel), as opposed to 86% of Rictor+/+NIC mice. This evidence concerns the gene RICTOR and neoplasm.
