miR-203a-A multifaceted regulator modulating cancer hallmarks and therapy response

Area of Science:

• Molecular Biology
• Genetics
• Oncology

Background:

• MicroRNAs (miRNAs) are small noncoding RNAs regulating gene expression.
• Dysregulated miRNA expression is implicated in human diseases, particularly cancer.
• miR-203a is a frequently altered miRNA in various cancer types.

Purpose of the Study:

• To review the multifaceted roles of miR-203a in cancer.
• To explore miR-203a's impact on cancer hallmarks and oncogenesis.
• To assess miR-203a's potential in cancer diagnosis, prognosis, and therapy.

Main Methods:

• Literature review of studies investigating miR-203a in cancer.
• Analysis of miR-203a's regulatory mechanisms and target genes.
• Examination of miR-203a's involvement in cancer hallmarks and chemoresistance.

Main Results:

• miR-203a modulates key cancer hallmarks including proliferation, invasion, metastasis, cell death, and angiogenesis.
• miR-203a functions as a tumor suppressor or oncogene depending on the cancer type.
• miR-203a is detectable in biofluids, suggesting biomarker potential.
• miR-203a enhances sensitivity to several chemotherapeutic agents.

Conclusions:

• miR-203a is a critical regulator of cancer cell behavior and oncogenesis.
• miR-203a holds promise as a diagnostic and prognostic biomarker.
• Targeting miR-203a may improve chemotherapeutic efficacy in cancer treatment.
