SMG7 and breast cancer: As shown in the Supplementary Figure S1, we found that 16 out of 18 events (MARK3 exon 15; DST exon 93; TBC1D13 exon 3; MYOF exon 17; DCUN1D5 exon 4; FGFR1OP2 exon 4; FNBP1 exon 10; SYNE2 exon 106; SLK exon 13; ADD3 exon 13; USO1 exon 15; KIF13A exon 38; ATP11C exon 29; SMARCA1 exon 13; ACIN1 exon 4; SMG7 exon 18) were in the same direction (inclusion or skipping) also in low-metastatic T47D compared to high-metastatic BT-549 breast cancer cell lines.
