In addition to LRRFIP2, CCDC50, another splicing candidate of ESRP1, also showed skipping exon event (Supplementary Table 11) and BICD2 showed retained intron event (Supplementary Table 10) occurring in gastric cancer cells depending on the expression of ESRP1 (Supplementary Fig. 4). This evidence concerns the gene LRRFIP2 and gastric cancer.
