Master Transcription Regulators02:23

Master Transcription Regulators

7.8K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Transcription Factors02:16

Transcription Factors

82.9K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Nucleosome Remodeling02:54

Nucleosome Remodeling

11.2K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.

The Eukaryotic Promoter Region02:40

The Eukaryotic Promoter Region

18.9K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences.  The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

Transcription01:10

Transcription

157.1K
Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

Transcription Elongation Factors02:35

Transcription Elongation Factors

14.1K
Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...

Area of Science:

  • Neuroscience
  • Sleep Science
  • Motor Learning

Background:

  • Sensory stimulation offers a non-invasive, drug-free method to enhance sleep.
  • While auditory and vestibular stimulation improve sleep, their cognitive and cellular impacts are not fully understood.

Purpose of the Study:

  • To investigate the effects of vestibular stimulation through rocking on sleep architecture.
  • To examine the impact of rocking on motor learning, gene expression, and synaptic organization in the motor cortex.

Main Methods:

  • Mice underwent eleven consecutive days of rocking.
  • Sleep architecture, motor learning performance, cortical gene expression, and synaptic density were analyzed.

Main Results:

  • Rocking significantly increased sleep duration and consolidation in mice.
  • Enhanced sleep correlated positively with improved motor learning performance.
  • Molecular analysis revealed changes in genes related to glutamatergic signaling and synaptic plasticity, with increased excitatory synapse density in the motor cortex.

Conclusions:

  • Vestibular stimulation via rocking enhances sleep quality and duration.
  • Sleep enhancement through rocking facilitates motor learning by modulating neuroplastic mechanisms in the motor cortex.
