IncRNA-HAGLROS, IncRNA-AKO2339, etc. can promote the formation of gastric cancer tumors, and their high expression is a predictive molecule for the poor prognosis of gastric cancer.[13,14] The expression of IncRNA-HMlincRNA717 decreases in gastric cancer, which is closely related to the recurrence of gastric cancer.[15] TUG1 gene is located in the long arm of human autosome 22, zone 2, subband 2 (22q112.2), and lncRNA. The gene discussed is TUG1; the disease is gastric cancer.
