Insights

MicroRNAs (miRNAs) are linked to Fragile X syndrome, a common cause of inherited intellectual disability. This review explores the miRNA pathway's role in Fragile X syndrome and intellectual disability.

Area of Science:

  • Genetics
  • Molecular Biology
  • Neuroscience

Background:

  • Cognitive deficits cause intellectual disability (ID).
  • Inherited ID pathogenesis is illuminated by genetic studies.
  • Fragile X syndrome, a common inherited ID, results from loss of functional Fragile X Mental Retardation Protein (FMRP).

Purpose of the Study:

  • To review the role of the microRNA (miRNA) pathway in Fragile X syndrome.
  • To discuss the implications of miRNA in intellectual disability generally.

Main Methods:

  • Literature review of studies on miRNA and Fragile X syndrome.
  • Analysis of miRNA pathway involvement in Fragile X pathogenesis.
  • Synthesis of current understanding of miRNA in intellectual disability.

Main Results:

  • MicroRNAs (miRNAs) are endogenous RNAs (18-25 nucleotides) involved in biological pathways.
  • Recent research connects the miRNA pathway to Fragile X syndrome.
  • The miRNA pathway is implicated in the regulation of FMRP and other factors relevant to Fragile X.

Conclusions:

  • The miRNA pathway plays a significant role in Fragile X syndrome.
  • Understanding miRNA mechanisms offers insights into intellectual disability pathogenesis.
  • Targeting miRNA pathways may present therapeutic strategies for intellectual disability.

MicroRNAs

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...

Experimental 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...

siRNA - 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...
RNA Interference01:23

RNA 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...
