Figure 1 Molecular mechanism of long noncoding RNAs in gastric cancer. A: MicroRNA (miRNA) sponge. H19 and GAPLINC, acting as molecular sponges, bind to miR-675 and miR-211-3p, thus increasing the expression of their target genes RUNX1 and Cd44; B: mRNA stability. Target transcripts are stabilized or decayed when long noncoding RNA (lncRNA) binds to mRNA; C: Genetic variants. Genetic variants located at lncRNAs influence the expression of lncRNA; D: Alternative splicing. LINC00477 generates three transcripts based on alternative splicing; E: Transcription factor binding. Transcription factor directly interacts with the lncRNA PVT1 and regulates its expression; F: Epigenetic modification; G: DNA methylation. DNA methylation sites located at or near lncRNA regulate lncRNA expression; H: Histone modification. H3K27me results in suppression or gain of transcriptional activity.
