Background: However, advanced technologies have been developed in the treatment of various cancers, but the mortality rate from cancer is still very high. Drug resistance is a major problem for patients with cancer, which causes the treatment process to fail. In addition to inhibiting drug resistance, targeted therapy is also very important in treatment.
Main body: Nowadays, miRNAs have gained increasing interest as they play a major role in both drug resistance and targeted therapy. MicroRNA (miRNA) is an important part of non-coding RNA that regulates gene expression at a post-transcriptional level. The prevailing studies about miRNA expression have been expanded into a variety of neoplasms. MiR-424 and miR-631 targets genes involved in various cellular processes and can participate in proliferation, differentiation, apoptosis, invasion, angiogenesis, and drug resistance and sensitivity.
Conclusion: In this study, we focus on the role of miR-424 and miR-631 in many cancer types by displaying the potential target genes associated with each cancer, as well as briefly describing the clinical uses of miR-424 and miR-631 as a diagnostic and predictive tool in malignancies.
