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

Dec 17, 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.

MicroRNAs (miRNAs) are a class of non-coding RNAs that play important roles in regulating gene expression. The majority of miRNAs are transcribed from DNA sequences into primary miRNAs and …

Oct 7, 2024 · Here's what the discovery of microRNA means and how it may affect human health. What is microRNA, anyway? The discovery makes it possible to manipulate which genes are activated or …

3 days ago · Despite well-established roles of microRNAs (miRNAs) as tumour suppressors or oncogenes, miRNA-based diagnostics, prognostic tools and treatments have yet to be incorporated …

Jul 21, 2025 · Within our cells exists a family of tiny molecules called microRNA, which act as regulators of cellular activity. These are not genes that create proteins, but small, non-coding pieces of RNA …

13 hours ago · Together, the findings establish microRNA strand selection as a regulated layer of gene control and demonstrate how artificial intelligence can uncover hidden biological rules conserved …

6 days ago · MicroRNAs (miRNAs) are short, noncoding RNAs that are key players in regulating genes after they are transcribed, by targeting mRNAs for degradation or inhibiting translation. The …

Jun 3, 2020 · MicroRNAs (miRNAs) are short, regulatory RNAs that act as post-transcriptional repressors of gene expression in diverse biological contexts.

A microRNA is a single-stranded RNA of short length (18–25 nucleotides) whose function is not to encode proteins, but to regulate other biological processes such as cell proliferation or differentiation, …
