GATAD2B and neoplasm: Consistent with the ability of GATAD2B to drive in vivo metastasis of 393 P cells in our primary screen, necropsies of tumor-bearing HBEC-iKRASG12D-GATAD2B mice revealed distant metastases (N = 4/5 mice examined) to multiple lymph nodes and other organ sites (Supplementary Fig. 4f).
