Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

13.9K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Functional Brain Systems: Reticular Formation

3.2K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

RNA Editing02:23

RNA Editing

9.4K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

siRNA - Small Interfering RNAs

17.5K
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...

Area of Science:

  • Molecular Biology
  • Neuroscience
  • Genetics

Background:

  • Circular RNAs (circRNAs) are non-linear RNA molecules with a closed-loop structure, lacking 5' to 3' polarity and poly(A) tails.
  • They are primarily formed through back-splicing of exonic regions.
  • CircRNAs are tissue-specific, evolutionarily conserved, and play regulatory roles by interacting with microRNAs and proteins.

Purpose of the Study:

  • To review the current understanding of circular RNA biogenesis and properties.
  • To highlight the significant functions of circRNAs within the central nervous system (CNS).
  • To emphasize the critical involvement of circRNAs in the development and progression of CNS diseases.

Main Methods:

  • Literature review of studies on circRNA biogenesis, function, and CNS roles.
  • Analysis of research focusing on circRNA involvement in neurological disorders.
