The microRNA and the perspectives of miR-302

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules.
• They regulate gene expression post-transcriptionally via mRNA degradation or translational inhibition.
• MiRNAs are crucial in physiological and pathological processes, notably in cancer development and progression.

Purpose of the Study:

• To review the fundamental aspects of non-coding RNAs, focusing on miRNAs.
• To discuss miRNA biogenesis, circulating miRNAs, and miRNA delivery systems.
• To present the specific role and potential applications of the miR-302 family in cancer, induced pluripotent stem cells (iPSCs), and heart disease.

Main Methods:

• Literature review of non-coding RNA and miRNA research.
• Analysis of miRNA biogenesis pathways.
• Review of studies on circulating miRNAs and direct miRNA delivery strategies.
• Case study focusing on the miR-302 family's involvement in specific diseases.

Main Results:

• MiRNAs are key regulators of gene expression with broad biological functions.
• Various methods for miRNA detection, quantification, and therapeutic delivery are being developed.
• The miR-302 family shows significant potential in targeting cancer, reprogramming cells to pluripotency, and treating cardiac conditions.

Conclusions:

• MiRNAs represent a significant class of regulatory molecules with therapeutic potential.
• Understanding miRNA biology is crucial for developing novel diagnostic and therapeutic strategies.
• The miR-302 family exemplifies the targeted therapeutic capabilities of specific miRNAs in complex diseases.
