Histone Modification02:32

Histone Modification

16.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

Streamlines, Streaklines, and Pathlines

2.0K
A streamline represents the trajectory that is always tangent to the fluid's velocity vector at any given point. The velocity of a fluid particle is always directed along the streamline, ensuring the particle continuously follows the streamline's path. Streamlines are particularly useful for visualizing the overall direction of flow in a fluid system, and they provide an instantaneous representation of the flow's velocity field. In steady flow, where conditions do not change over...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Behavior Modification

755
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.

Bernoulli's Equation for Flow Along a Streamline01:30

Bernoulli's Equation for Flow Along a Streamline

1.5K
Bernoulli's equation relates the energy conservation in a fluid moving along a streamline. The equation applies to incompressible and inviscid fluids under steady flow. For such a flow, Newton's second law is applied to a small fluid element, which experiences forces due to pressure differences, gravity, and velocity variations. The force balance leads to the following form of Bernoulli's equation:

Area of Science:

  • Neuroscience
  • Stem Cell Biology
  • Developmental Biology

Background:

  • Differentiation protocols for human pluripotent stem cells (hPSCs) can be complex and costly.
  • Extrinsic patterning factors may introduce unintended effects in hPSC models of brain development, potentially masking disease phenotypes.

Purpose of the Study:

  • To present two simplified cerebellar differentiation protocols for hPSCs.
  • To offer alternatives to existing protocols with fewer patterning factors and reduced material requirements.

Main Methods:

  • Developed two distinct protocols for hPSC differentiation into cerebellar structures.
  • One protocol generates free-floating 3D cerebellar organoids with relevant brain development morphologies.
  • The second protocol utilizes an adherent 2D monolayer system to produce functional cerebellar neurons.

Main Results:

  • The 3D organoid protocol produced structures resembling sub/ventricular zones and rhombic lips.
  • The 2D monolayer protocol yielded functional cerebellar neurons expressing cerebellar markers.
  • These neurons exhibited neuron-like calcium influxes, indicating functional activity.

Conclusions:

  • Two streamlined protocols for hPSC-derived cerebellar differentiation are presented.
  • These protocols offer researchers simpler, cost-effective options for modeling brain development and pathophysiology.
  • The methods provide a foundation for testing other streamlined neural differentiation strategies.
