| MicroRNAs (miRNAs) have had a revolutionary impact on cancer research over the recent years. They
emerge as important players in tumourigenesis, leading to a paradigm shift in oncology. Ovarian cancer
is the leading cause of death among gynaecologic malignancies. Therefore, there is a strong need for
prognostic and predictive markers for early diagnosis which helps optimize and personalize treatment.
Asymptomatically, ovarian cancer is often diagnosed at advanced and incurable stages. Efficient target-ing and sustained release of miRNAs/anti-miRNAs using nanoparticles conjugated with antibodies and/
or peptides could reduce the required therapeutic dosage while minimizing systemic and cellular tox-icity. Given miRNAs importance in clinical oncology, here we focus on the development of miRNA nano-formulations to achieve enhanced cellular uptake, bioavailability and accumulation at the tumour site.
Although many obstacles need to be overcome, miRNA therapy could be a powerful tool for ovarian
cancer prevention and treatment. In this review, we discuss about the emerging roles of miRNAs in vari-ous aspects of ovarian cancer. |
