Summary
MicroRNAs (miRNAs) are small RNAs regulating gene expression and are implicated in cancer. Research is exploring therapeutic strategies targeting these molecules for cancer treatment.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- MicroRNAs (miRNAs) are conserved non-coding small RNAs regulating gene expression post-transcriptionally.
- Initially discovered in worms, miRNAs are now recognized as crucial in both invertebrates and vertebrates.
- They function by targeting messenger RNA (mRNA) stability and translation.
Purpose of the Study:
- To review the diverse roles of microRNAs in cancer initiation and progression.
- To discuss tools and techniques for correcting miRNA expression in vivo.
- To evaluate the therapeutic potential of targeting microRNAs for cancer treatment.
Main Methods:
- Review of recent advancements in miRNA identification and target prediction computational engines.
- Utilization of biochemical tools and techniques to modulate miRNA activity.
- Emergence and application of miRNA-centric animal models in research.
Main Results:
- MicroRNAs are strongly implicated in cancer, acting as oncogenes or tumor/metastasis suppressors.
- Significant progress in understanding miRNA functions driven by technological advancements.
- Therapeutic targeting of miRNAs for cancer is gaining traction.
Conclusions:
- MicroRNAs play a critical role in cancer development and progression.
- Developing tools to modulate miRNA activity offers potential therapeutic avenues.
- Further basic, translational, and clinical research is needed to validate miRNA-based cancer therapies.

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...

02:30siRNA - Small Interfering RNAs
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
