Summary
MicroRNAs are small RNA molecules regulating protein expression. Their abnormal levels are linked to diseases, and they can circulate in the blood, offering diagnostic and therapeutic potential.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Context:
- MicroRNAs (miRNAs) are short, non-coding RNA molecules crucial for gene regulation.
- Aberrant miRNA expression is implicated in various diseases, including degenerative, inflammatory, and neoplastic conditions.
- miRNAs can be detected in circulation, bound to proteins or within exosomes, suggesting roles beyond intracellular regulation.
Purpose:
- To explore the regulatory roles of microRNAs in cellular processes.
- To understand the association of microRNA deregulation with disease pathology.
- To investigate the potential of circulating microRNAs as biomarkers and therapeutic targets.
Summary:
- MicroRNAs (miRNAs) are ~22 nucleotide non-protein-coding RNAs that regulate gene expression post-transcriptionally by binding to mRNA.
- Dysregulation of miRNA expression is a hallmark of numerous pathological conditions, including cancer and inflammatory diseases.
- Circulating miRNAs, found in blood exosomes or associated with proteins, are being investigated for their diagnostic and therapeutic potential.
Impact:
- Understanding miRNA function is key to deciphering disease mechanisms.
- Circulating miRNAs may serve as novel, minimally invasive biomarkers for early disease detection.
- Therapeutic strategies involving miRNA mimics (siRNA) and inhibitors (antagomirs) show promise for future treatments.

01:22MicroRNAs
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

02:15Experimental RNAi
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
01:23RNA Interference
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

02:57piRNA - Piwi-interacting RNAs
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...
