GSE87785: Sequencing-based analyses characterize a tumor suppressive role of mir-1271 repressed by DNA hypermethylation in gastric cancer

To identify tumor suppressive microRNAs repressed by DNA hypermethylation in gastric cancer (GC), we analyzed methylome and miRNome of EpCAM+/CD44+ GC cells. Among a set of microRNAs hypermethylated and downregulated in GC, mir-1271 was uncovered as a microRNA repressed by DNA hypermethylation in GC. Forced expression of mir-1271 significantly suppressed growth, migration, and invasion of GC cells both in vitro and in vivo. To identify target genes and cancer signaling pathways regulated by mir-1271, we examined differentially-expressed genes responsive to mir-1271 by performing RNA-sequencing.
