Abstract

Numerous aberrantly expressed microRNAs (miRNAs/miRs) have been identified in gastric cancer (GC); however, only a fraction of these have been functionally investigated and novel deregulated miRNAs in GC remain to be explored. Through examining two public miRNA expression profile datasets, the present study identified aberrantly expressed miRNAs in GC. One of these miRNA, miR‑564, was identified to be downregulated in GC, which was validated in tissue samples from patients with GC by reverse transcription‑quantitative polymerase chain reaction analysis. Targets of miR‑564 were then predicted bioinformatically, including transcription factor E2F3 (E2F3), which was identified to be functionally enriched in several cancer signaling pathways. Furthermore, overexpression of miR‑564 decreased the activity of a luciferase reporter carrying the 3'‑untranslated region of E2F3, in addition to the mRNA and protein level of E2F3, indicating that miR‑564 directly targets E2F3. These data suggest that by targeting E2F3, miR‑564 may act as a tumor suppressor gene in gastric carcinogenesis.
