In order to verify the accuracy of the aforementioned bioinformatics analysis results, the expression of CAMK2N1, hsa-miR-378a-3p, and SNHG10 were verified in five GC cell lines (AGS, MGC-803, BGC-823, HGC-27, and MKN-45) by RT-qPCR and Western blotting. The gene discussed is CAMK2N1; the disease is gastric cancer.
