Insights

MicroRNAs (miRNAs) regulate gene silencing and are crucial for brain development. This review highlights their role in cerebral corticogenesis, focusing on neuron birth and maturation.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally.
  • They are implicated in diverse biological processes, including development and disease.
  • While miRNA functions are known in many tissues, their role in the developing brain is less understood.

Purpose of the Study:

  • To review the current evidence for miRNA involvement in cerebral cortical development (corticogenesis).
  • To emphasize the specific pathways controlled by miRNAs during excitatory projection neuron development.
  • To consolidate understanding of miRNA functions in neurogenesis and neuronal maturation.

Main Methods:

  • Literature review of studies investigating miRNA function in corticogenesis.
  • Analysis of research on miRNA targets and pathways in neural development.
  • Synthesis of findings related to neuron production and maturation.

Main Results:

  • Evidence suggests miRNAs play significant roles in multiple stages of cerebral cortical development.
  • Specific miRNAs and their targets are involved in regulating the proliferation and differentiation of neural progenitor cells.
  • miRNAs are critical for the maturation and functional integration of excitatory projection neurons.

Conclusions:

  • MicroRNAs are key regulators of excitatory neuron development in the cerebral cortex.
  • Further research into miRNA pathways will illuminate mechanisms of corticogenesis and potential therapeutic targets.
  • Understanding miRNA contributions is essential for deciphering the complexities of brain development.

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

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 ends...
