| Research Abstract |
In the present study, epigenetic therapy using DNA methylation inhibitors and histone deacetylase inhibitors activates the tumor suppressor microRNA miR-512-5p in human gastric cancer cells. Activation of miR-512-5p by epigenetic therapy induces suppression of MCL-1, resulting in apoptosis of gastric cancer cells.
In addition, our study suggests that microRNAs play important roles in the pathogenesis of functional gastrointestinal disorders including functional dyspepsia.
The results in the present study may provide a novel therapeutic approach for gastrointestinal malignancies as well as functional gastrointestinal disorders.
