Shape-velocity correlation defines polarization in migrating cell simulations [PDF]
, 2021 Cell migration plays essential roles in development, wound healing, diseases, and in the maintenance of a complex body. Experiments in collective cell migration generally measure quantities such as cell displacement and velocity. The observed short-time diffusion regime for mean square displacement in single-cell migration experiments on flat surfaces ...

Heterogeneity of Organization of Subcompartments in DSB Repair Foci
Frontiers in Genetics, 2022 Cells assemble compartments around DNA double-strand breaks (DSBs). The assembly of this compartment is dependent on the phosphorylation of histone H2AX, the binding of MDC1 to phosphorylated H2AX, and the assembly of downstream signaling and repair ...

Lipid Microdomains in Cell Nucleus [PDF]
Molecular Biology of the Cell, 2008 It is known that nuclear lipids play a role in proliferation, differentiation, and apoptotic process. Cellular nuclei contain high levels of phosphatidylcholine and sphingomyelin, which are partially linked with cholesterol and proteins to form lipid–protein complexes.

Thermodynamics and thermoeconomics of cell division in presence of exogenous materials in nucleus [PDF]
arXiv, 2022 Cell division is an essential biological process, and regulation of cell division is of relevance for many important fields of biology and medicine. Introducing exogenous substances, such as nanoparticles, into the nucleus, has been experimentally studied to regulate the division of cells.

A role for the cleaved cytoplasmic domain of E-cadherin in the nucleus [PDF]
, 2008 Cell-cell contacts play a vital role in intracellular signaling, although the molecular mechanisms of these signaling pathways are not fully understood. E-cadherin, an important mediator of cell-cell adhesions, has been shown to be cleaved by γ-secretase.
