CD44 and gastric cancer: Based on over-lapping analysis of top 60 changes in alternative splicing events (|ΔPSI|≥ 50%, P < 0.05) in MKN-45 cells over-expressing SNORA37 (Fig. 3c, Additional file 1: Table S5) and gastric cancer tissues (Fig. 3d, Additional file 1: Table S6), only CD44 and PRMT2 were found to exhibit consistent alternative splicing events and selected for further analysis.
