Experimental RNAi

6.5K
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...

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

siRNA - Small Interfering RNAs

13.4K
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...

MicroRNAs

3.0K
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...

RNA Interference01:23

RNA Interference

24.2K
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...

Area of Science:

  • Stem cell biology
  • Epigenetics
  • Non-coding RNA research

Background:

  • Non-coding RNAs (ncRNAs) are crucial regulators of pluripotency in embryonic stem cells.
  • The specific role of natural antisense transcripts (NATs), a class of ncRNAs, in embryonic stem cells remains largely unexplored.

Purpose of the Study:

  • To investigate the role of NATs in the maintenance of pluripotency in embryonic stem cells.
  • To confirm the expression of NATs corresponding to key pluripotency factors Oct4, Nanog, and Sox2.

Main Methods:

  • Confirmation of NAT expression in embryonic stem cells.
  • Experimental manipulation of Sox2-NAT levels via overexpression.
  • Analysis of Sox2 protein and mRNA levels following Sox2-NAT manipulation.

Main Results:

  • NATs corresponding to the pluripotency genes Oct4, Nanog, and Sox2 were confirmed to be expressed in embryonic stem cells.
  • Overexpression of Sox2-NAT led to a decrease in Sox2 protein levels.
  • Sox2-NAT overexpression resulted in a slight increase in Sox2 mRNA levels.

Conclusions:

  • NATs are expressed in embryonic stem cells and are associated with key pluripotency genes.
  • NATs, similar to other ncRNAs, are implicated in the regulation and maintenance of pluripotency.
  • Further research into NATs could reveal novel mechanisms of pluripotency control.
