What is known about viscoelASTICITY OF CHROMATIN? 


Best insight from top research papers

The viscoelasticity of chromatin has been investigated in several studies. It has been found that the diffusion behavior of particles in chromatin deviates from the traditional Stokes-Einstein relation, indicating a non-sticky diffusion process . At short times, large particles are temporarily "caged" by chromatin spatial constraints, forming effective domains . The viscoelastic properties of the nuclear interior of a living human cell have been characterized, showing a transition from a viscous fluid to a viscoelastic medium depending on the size of the tracer proteins . The chromatin network in the cell nucleus is suggested to form a random obstacle network rather than a self-similar structure . These findings provide insights into the physical properties of chromatin and how it affects enzymatic reactions and target search processes within the nucleus.

Where viscoelastic dampers use?5 answersViscoelastic dampers are extensively utilized in various engineering applications for vibration control and seismic mitigation. These dampers, also known as viscous dampers, offer significant damping and yield capacity, enabling them to dissipate energy induced by seismic actions and reduce structural stresses. They are commonly employed in high-rise buildings, bridges, and other structures to enhance seismic response and reduce vibrations. Viscoelastic materials are used for passive vibration control, with their damping properties investigated through simulations and numerical analyses to predict dynamic behavior and establish relationships between dynamic parameters for noise and vibration control. Additionally, high-performance acrylate viscoelastic dampers have been developed for low-frequency vibration control in building structures, showcasing excellent energy dissipation capacity and adaptability to varying environmental conditions.
What is viscoelastic fluid?5 answersViscoelastic fluid is a unique type of fluid that combines viscous and elastic properties, making it distinct from traditional Newtonian fluids. These fluids exhibit characteristics like turbulent drag reduction, elastic turbulence, and shear-thinning behavior, where viscosity changes significantly with shear rate. Understanding the rheology of viscoelastic fluids is crucial due to their applications in various fields such as petrochemicals, food, and medical industries. Researchers have developed models like Giesekus and FENE-P to study the shear-thinning behavior of viscoelastic fluids, highlighting differences in critical values and apparent viscosity effects. The study of viscoelastic fluids involves complex constitutive equations for stress, with advancements like the viscoelasticNet framework using deep learning to model stress fields based on velocity flow data.
Chromatin condensation is correlated to the cytoskeletal forces?5 answersChromatin condensation is correlated to cytoskeletal forces. The movement of genes and regulatory factors in chromatin remodeling is influenced by active force generation from cytoskeletal motor activity propagated through the LINC complex. Chromatin movements are enhanced by cytoskeletal forces and are dependent on the viscoelasticity of the DNA-protein polymer network. Modulation of chromatin condensation state dramatically alters chromatin movements. Stabilization of perinuclear actin strengthens the interactions of lamin A with chromatin. Actin organization affects the mobility of nuclear lamina proteins and the dynamics of core histone H2B and heterochromatin HP1α proteins with chromatin. These findings suggest that cytoskeletal forces play a role in chromatin condensation and organization.
How mechanobiology relates to the nucleus?4 answersMechanobiology is the study of how living cells sense and respond to mechanical stimuli. Recent advances in mechanobiology have shown that the cell nucleus, in addition to the plasma membrane and cytoskeleton, can independently sense mechanical stimuli. The nucleus can sense mechanical cues through the tension exerted on the outside local microenvironment via adhesions, which leads to 3D modifications of the nucleus. Changes in nuclear structures have been found to play a role in cellular mechanosensing and can affect chromatin organization, gene expression, and cell function. Understanding how the nucleus senses and responds to mechanical stimuli is challenging due to technical limitations. However, new tools, such as a magnetic force actuator, combined with high-resolution imaging, have been developed to directly deform the cell nucleus and study its real-time dynamics. By studying the relationship between mechanical forces and nuclear deformations, researchers can gain insights into how forces affect genome function.
