Abstract:
microRNA(miRNA) is a kind of non-coding RNA that has a regulatory function on coding miRNA. miRNA can target the 3 UTR of mRNA and inhibit its gene expression by either inhibiting its translation or promoting its degradation. miRNAs are thus considered to be oncogenic or antineoplastic, depending on their downstream target mRNAs. Besides their clinical application in cancer treatment, diagnosis, and prognosis, miRNA has also recently been reported to be involved in cancer chemotherapy and chemoprevention. This review focuses on the implication of miRNA in cancer chemoprevention and cancer control as well as molecular mechanisms underlying those biological effects.
Insights
MicroRNAs (miRNAs) regulate gene expression and can act as oncogenes or antineoplastics. This review explores their role in cancer chemoprevention and control.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are non-coding RNAs that regulate gene expression by targeting messenger RNAs (mRNAs).
- miRNAs can influence gene expression by inhibiting translation or promoting mRNA degradation.
- Their dual role as oncogenic or antineoplastic depends on their specific mRNA targets.
Purpose of the Study:
- To review the implications of miRNAs in cancer chemoprevention.
- To explore the role of miRNAs in cancer control strategies.
- To elucidate the molecular mechanisms underlying these effects.
Main Methods:
- Literature review of scientific articles on miRNA function in cancer.
- Analysis of studies investigating miRNA involvement in chemoprevention and chemotherapy.
- Synthesis of information on molecular pathways regulated by miRNAs in cancer.
Main Results:
- miRNAs are implicated in both promoting and suppressing cancer development.
- Specific miRNAs show potential for cancer chemoprevention by targeting oncogenic pathways.
- miRNAs are increasingly recognized for their roles in cancer treatment and prognosis.
Conclusions:
- miRNAs are critical regulators in cancer biology with significant potential in chemoprevention.
- Understanding miRNA mechanisms can lead to novel strategies for cancer control.
- Further research is needed to fully harness miRNA therapeutics for cancer management.
