Micro ribonucleic acid (microRNA, miRNA, μRNA) are small, single-stranded, non-coding RNA molecules containing 21–23 nucleotides. [1] .

Oct 11, 2025 · A microRNA (miRNA) is a small molecule in cells, typically about 21–25 nucleotides in length, that plays a crucial role in the regulation of gene expression.

Jan 22, 2025 · MicroRNA, or miRNA, is a small strand of RNA that controls gene expression. Gene expression here refers to how much of the corresponding protein is made from a gene. …

Jan 13, 2025 · MicroRNAs are regulators of gene expression and their dysregulation can lead to various diseases. MicroRNA-135 (MiR-135) exhibits brain-specific expression, and performs …

There are many different small RNA species, including miRNA (microRNA), siRNA (small interfering RNA), and piRNA (Piwi-interacting RNA). piRNA, miRNA, and siRNA have in …

MicroRNAs (miRNAs) are a class of small noncoding RNAs, which function in posttranscriptional regulation of gene expression. They are powerful regulators of various cellular activities …

Jun 1, 2025 · MicroRNAs (miRNAs) are a class of small, non-coding RNA molecules that are ubiquitously distributed across eukaryotic organisms. Through complementary base pairing …

Mature microRNAs (miRNAs) are a class of naturally occurring, small non-coding RNA molecules, about 21–25 nucleotides in length.

Jun 28, 2023 · Here, we summarize the current understanding of miRNA biogenesis, function and regulation, and outline challenges to address in the future.

microRNA controls gene expression mainly by binding with messenger RNA (mRNA) in the cell cytoplasm. Instead of being translated quickly into a protein, the marked mRNA will be either …
