MicroRNA‑381 regulates the growth of gastric cancer cell by targeting TWIST1.

Abstract:

:Gastric cancer (GC) has one of the highest mortality rates among all types of cancer in the world. At present, an efficient treatment for GC remains elusive. Studies have demonstrated that microRNAs (miRs) are abnormally expressed in cancer, and that these serve important roles in the development and metastasis of various human tumors, including GC. It has been suggested that regulation of miRs may bring about new developments in GC therapy. miR‑381 has been reported to be downregulated in human cancer, and it regulates cancer cell growth in numerous types of cancer. The present study reports that miR‑381 was downregulated in GC cells, and upregulation of miR‑381 may inhibit GC cell growth, which may be attributed to the inhibition of cell proliferation and the promotion of apoptosis. Furthermore, Twist‑related protein 1 (TWIST1) was predicted and confirmed to be a direct target of miR‑381 by dual‑luciferase assay in GC. Upregulation of miR‑381 caused a decrease in the expression of TWIST1 at the mRNA and protein levels in GC cells. Taken together, the present study demonstrated that miR‑381 is downregulated in GC cells, and that miR‑381 may inhibit GC cell growth. Therefore, miR‑381 may serve as a novel target for the clinical treatment of GC in the future.
