FAST does not require TIA1 or TIAL1 to activate to FGFR2 exon IIIb. (A) HEK293T cells were transfected with siRNAs targeting TIA1 or TIAL1 as well as the minigene pI12DE-WT and pcDNA3-Flag-FAST (1 μg). Proteins were extracted and monitored by Western blot analysis, and RNAs were analyzed for single and double-inclusion transcripts. (B) HEK293T cells were simultaneously transfected with TIA1 and TIAL1 siRNAs as well as pI12DE-WT and pcDNA3-Flag-FAST (1 μg) and analyzed as described for A.
