The open reading frame (ORF) of human FAT1 and ZNF750 transcripts were generously provided by Timothy Chan's group from Memorial Sloan-Kettering Cancer Center27 (link) and Paul Khavari's group from Veterans Affairs Palo Alto Healthcare System24 (link), respectively. Both ORFs were sub-cloned into lentiviral based expression vector SHC003 (Sigma-Aldrich) using Nhe I and Fse I cloning sites. SHC003-Turbo-GFP was used as control (Sigma-Aldrich). The lentiviral based shRNA vectors (shXPO1 and shFAT2 sequences are listed in Supplementary Table 13b) were generated with PLKO.1 backbone (Sigma-Aldrich) using Age I and EcoR I cloning sites. SHC002-Scramble shRNA was used as control (Sigma-Aldrich). The cloning primers are listed in Supplementary Table 13c.
