    Area of Science:

    • Biochemistry and Molecular Biology
    • Genetics and Genomics

    Background:

    • The discovery of RNA interference (RNAi) and subsequent identification of microRNAs (miRNAs) have revolutionized the understanding of gene regulation.
    • miRNAs are endogenous small RNA molecules (~22 nucleotides) that post-transcriptionally regulate gene expression by repressing protein synthesis.
    • An estimated 600+ miRNAs in mammalian cells regulate approximately 30% of all genes, highlighting their widespread biological significance.

    Discussion:

    • Current understanding of disease molecular mechanisms is incomplete without considering the role of miRNA.
    • miRNA-based therapies represent a promising frontier in RNA interference (RNAi) drug development.
    • While progress in cancer research is notable, miRNA applications in other biomedical areas are still emerging.
