Microrna vs sirna

4 comments. share. save. hide. report Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA non-coding RNA molecules, typically 20-27 base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. miRNAs resemble the small interfering RNAs (siRNAs) of the RNA interference (RNAi) pathway, except miRNAs derive from regions of RNA transcripts that fold back on themselves to form short hairpins, whereas siRNAs derive from longer regions of double-stranded RNA. Conclusively, the microRNA mediated therapies might be a good choice in comparison with shRNA or siRNA. Yet, a large number of data needed to understand the exact function, mechanism and action of miRNA.

Plant secondary siRNA production determined by microRNA-duplex structure Proc Natl Acad Sci U S A. 2012 Feb 14;109(7):2461-6. doi: 10.1073/pnas.1200169109. There are two types of shRNA scaffolds, simple hairpin or microRNA-based. The simple hairpin has a stem-loop structure where the active and passenger strands are complementary and expressed from a Pol III promoter, such as U6 and H1 (Figure 1B).

The siRNA binds to a second enzyme called RNA-induced silencing complex (RISC), the siRNA/RISC complex then attaches to a disease-associated mRNA. Now, double-stranded, RISC destroys both RNA strands—siRNA and mRNA—and the disease is stopped.

A considerable body of literature now classifies miRNAs as RNAi molecules. 15,25,26,27 The major difference between siRNAs and miRNAs is that the former are highly specific with only one mRNA target, whereas the latter have multiple targets. The therapeutic approaches of siRNAs and miRNAs are therefore very different. $\begingroup$ I have looked up more about siRNA and see that mmicroRNA does not have to be 100% specific, but siRNA does.

The RNase III-enzyme Dicer produces small RNAs (smRNAs) in both microRNA (miRNA) and RNA interference (RNAi) pathways. m … A microRNA (abbreviated miRNA) is a small single-stranded non-coding RNA molecule (containing about 22 nucleotides) found in plants, animals and some viruses, that functions in RNA silencing and post-transcriptional regulation of gene expression. Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA non-coding RNA molecules, typically 20-27 base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. Evidence derived from the C. elegans system suggesting that different host gene products are required for siRNA-mediated RNA interference vs. miRNA-mediated translational repression (17, 25) suggests that siRNAs and miRNAs may not be functionally identical.

Can someone clarify between the two and let me know what we're supposed to know in regards to them? Thank you.
