MicroRNAs in prostate cancer: Functional role as biomarkers

Area of Science:

• Molecular Biology
• Oncology
• Biochemistry

Background:

• MicroRNAs (miRNAs) are small non-coding RNA molecules regulating gene expression post-transcriptionally.
• miRNAs play critical roles in various biological processes, including cancer development and progression.
• Dysregulated miRNA expression is frequently observed in cancer, suggesting their involvement in tumorigenesis.

Purpose of the Study:

• To review the current understanding of miRNA deregulation in prostate cancer.
• To elucidate the specific roles of miRNAs as oncogenes, tumor suppressors, and metastasis regulators in prostate cancer.
• To highlight the potential of miRNAs as biomarkers and therapeutic targets for prostate cancer.

Main Methods:

• Literature review of studies investigating miRNA expression and function in prostate cancer.
• Analysis of data on miRNA roles in oncogenesis, tumor suppression, and metastasis.
• Synthesis of information on clinical applications of miRNAs in prostate cancer diagnosis, prognosis, and therapy.

Main Results:

• Numerous miRNAs are deregulated in prostate cancer, impacting key cellular pathways.
• Specific miRNAs function as oncogenes promoting tumor growth or as tumor suppressors inhibiting it.
• miRNAs are implicated in regulating prostate cancer cell metastasis and invasion.

Conclusions:

• miRNAs are significantly involved in prostate cancer pathogenesis.
• miRNAs hold promise as sensitive and specific diagnostic and prognostic biomarkers for prostate cancer.
• Targeting miRNAs represents a potential novel therapeutic strategy for prostate cancer management.
