FAT4 and gastric cancer: Considering that miRNAs contribute to gene expression regulation36, we sought to identify upstream regulatory miRNAs of FAT4. After a comprehensive analysis, miRNA-93-5p was selected as a potential miRNA that binds with FAT4. A previous study showed that miR-93-5p enhances the proliferation, migration, and invasion of gastric cancer cells by activating the Hippo pathway, making it a potential diagnostic and therapeutic target for gastric cancer37.
