miR-455 inhibits cell proliferation and migration via negative regulation of EGFR in human gastric cancer

Epidermal growth factor receptor (EGFR) plays an important role in various types of cancer. However, the therapeutic agents that target EGFR have not produced favorable results in gastric cancer. miRNAs are known to regulate gene expression at the post-transcriptional level. We wondered if miRNAs could be potential therapeutic agents for the targeted therapy against EGFR. In this study, we found an increase in the copies of EGFR mRNA and the...
