Interestingly, the majority of the cell lines in ESRP1-low group (SNU668, SNU484, and MKN1) was found to be mesenchymal subtype, while the majority of the cell lines in ESRP1-high group (SNU638, SNU719, KATOIII, AGS, SNU601, SNU620, MKN45, NCI-N87, MKN74, SNU216, MKN28, and SNU16) was epithelial subtype (Supplementary Fig. 2)13, suggesting that ESRP1 expression may be involved in the determination of epithelial/mesenchymal phenotype of gastric cancer cells. Here, ESRP1 is linked to gastric cancer.
