Screening and genotyping survival analysis of m6A-related lncRNAs related to the prognosis of gastric cancer. A A co-expression network of LncRNA-mRNAs. Blue and yellow nodes represent m6A-related mRNAs and lncRNAs, respectively. B Forest plot showing m6A-related lncRNAs significantly associated with prognosis of gastric cancer patients. Cyan and magenta fonts denote favorable and adverse prognostic factors, respectively. C Expression profiles of candidate lncRNAs in TCGA gastric cancer tissues. Red and blue boxes represent tumor and normal tissues, respectively, whereas cyan and magenta fonts denote downregulated and upregulated lncRNAs, respectively. D Heatmap showing differentially expressed lncRNAs between normal and tumor tissues. Magenta and cyan color show highly and lowly expressed lncRNAs, respectively. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001, relative to corresponding normal tissues. E Identification of two molecular subtypes based on the candidate lncRNAs and Kaplan-Meier survival curve analysis. F Heatmap and clinicopathologic features of the two clusters defined by the prognosis-related m6A-related lncRNAs expression
