The function of miRNAs appears to be in gene regulation. For that purpose, a miRNA is complementary to a part of one or more messenger RNAs (mRNAs). Animal miRNAs are …

Nov 22, 2025 · microRNA (miRNA), small molecule in cells, typically about 21–25 nucleotides in length, that plays a crucial role in the regulation of gene expression. MicroRNA (miRNA) is …

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 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 …

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 …

They play a crucial role in the post-transcriptional regulation of gene expression by base-pairing with complementary sequences, primarily within the 3′ untranslated regions (3′UTRs) of target …

Explore how microRNA (miRNA) regulates gene expression and functions and holds potential for treating diseases like cancer and autoimmune disorders.

microRNAs (miRNAs) are small noncoding RNAs that play important roles in posttranscriptional gene regulation. In animal cells, miRNAs regulate their targets by translational inhibition and …

May 30, 2024 · Micro-RNAs (miRNAs) are a family of non-coding RNAs (ncRNAs) that regulate gene expression post-transcriptionally. Since their discovery in 1993, they have been the topic …
