Insights

microRNAs regulate gene expression and are vital for nervous system development. Dysregulation of these small RNAs contributes to motor neuron diseases like spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS).

Area of Science:

  • Molecular Biology
  • Neuroscience
  • Genetics

Background:

  • microRNAs (miRNAs) are endogenous non-coding RNAs regulating gene expression.
  • miRNA dysregulation is implicated in various diseases, including neurological disorders.
  • miRNA pathways are crucial for neuronal development and function.

Purpose of the Study:

  • To review the role of miRNAs in motor neuron disorders.
  • To focus on the involvement of miRNAs in spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS).

Main Methods:

  • Literature review of current knowledge on miRNAs in motor neuron disorders.
  • Analysis of studies investigating miRNA expression and function in SMA and ALS.

Main Results:

  • miRNAs play significant roles in the pathology of SMA and ALS.
  • Specific miRNAs and their targets are associated with disease mechanisms.
  • Evidence suggests miRNAs as potential therapeutic targets for motor neuron diseases.

Conclusions:

  • miRNAs are critical regulators in motor neuron function and development.
  • Aberrant miRNA activity contributes to the pathogenesis of SMA and ALS.
  • Further research into miRNA pathways may yield novel therapeutic strategies for motor neuron disorders.

MicroRNAs01:22

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...

Satellite Stem Cells and Muscular Dystrophy

Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

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...

Neural Regulation01:37

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
