We further designed primers across exon 11 for verification and found that, after overexpression of ESRP1, the truncated product (exon 11 skipping, 103 bp) of CLSTN1 increased, while the full length (exon 11 no skipping, 160 bp) decreased in gastric cancer cells (Fig. 5H). The gene discussed is CLSTN1; the disease is gastric cancer.
