title: MicroRNAs in gastric cancer metastasis.
abstract: Gastric cancer (GC) is common worldwide and has a high rate of metastasis. The underlying molecular mechanism of metastasis are not entirely clear. MicroRNAs (miRNAs) are small, non-coding RNA molecules that regulate gene expression post-transcriptionally and are reported to be involved in multiple steps of tumor metastasis. Clarifying their roles in GC metastasis will improve understanding of this disease. Here, we review the involvement of miRNAs in multiple steps of GC metastasis, including epithelial-mesenchymal transitions, anoikis, angiogenesis, invasion, and migration. The clinical application of miRNAs as prognostic biomarkers in GC is also discussed.
