Abstract

The invention belongs to the field of molecular biology and biomedicine, and particularly relates to gastric cancer prognosis model construction based on an m6A-related IncRNA network and clinical application. According to the invention, a relationship between m6A-related lncRNA and a total survival rate of the gastric cancer is analyzed, 11 m6A related lncRNA markers are found, and a prognosis model is constructed to predict the prognosis of the gastric cancer. The model for predicting the prognosis of the gastric cancer contains 11 IncRNAs related to the prognosis of the gastric cancer. Theinvention provides the prediction model constructed on the basis of the m6A-related IncRNA network to predict the prognosis of a gastric cancer patient; the feasibility of the model is verified in multiple data sets; and a reliable method is provided for analyzing the prognosis of the gastric cancer related LncRNA patient. The model provides a plurality of lncRNAs as biomarkers, the sensitivity and accuracy of predicting the prognosis of the gastric cancer are improved, the adverse prognosis risk of the gastric cancer patient is accurately predicted and evaluated, and key monitoring and effective intervention are performed on a high-risk patient, so that a death rate and a local recurrence rate of the gastric cancer patient are reduced, and the prognosis of the patient is improved.

Description

technical field [0001] The invention belongs to the fields of molecular biology and biomedicine, and specifically relates to the model construction and clinical application of gastric cancer prognosis based on m6A-related IncRNA network. Background technique [0002] Gastric cancer is one of the most common malignant tumors, and the death rate of gastric cancer ranks third among all tumors. About 80% of gastric cancer patients are diagnosed at advanced stage, which makes many patients have poor prognosis. Surgery is by far the most suitable treatment for gastric cancer. For patients with recurrent or unresectable advanced gastric cancer, the 5-year mortality rate remains 30% to 50%, and there is no satisfactory treatment. Therefore, it is necessary to explore potential biomarkers of gastric cancer, which can help improve the prognosis of patients. [0003] Long-chain non-coding RNA (LncRNA) refers to a type of RNA with a length greater than 200 bp, which has the function o...
