Finally, the analysis of genes differentially expressed in correlation with TC2N in GC suggested a widespread impact of TC2N on the transcriptome and an intensive connection between TC2N and genes related to human cancer and other diseases, such as CATSPERB, GALNT3 and RBM47. Taken together, we discovered that TC2N may play a role of oncogene in gastric cancer. The gene discussed is GALNT3; the disease is gastric cancer.
