Interestingly, among seven SNF5-deficient non-MRT lines (Fig. S3D), two of them, the rhabdomyosarcoma line KYM1 and the lung adenocarcinoma line HLC1, also displayed high levels of FGFR1 and FGFR2 transcripts, respectively (Fig. S3E and F), which were abrogated upon reconstitution of SNF5 (Fig. S3B and C). Here, FGFR2 is linked to lung adenocarcinoma.
