Computational Modeling and Experimental Findings on Nucleosome Constraining in Mitosis

Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division.

FAM110A's Dual Role: Orchestrating Microtubule-Actin Interactions in Mitosis

An international research collaboration, led by Prof. Dr. Robert Grosse (Centre for Integrative Biological Signalling Studies and Institute of Clinical and Experimental Pharmacology and Toxicology, University of Freiburg), Dr. Libor Macurek (Institute of Molecular Genetics, Czech Academy of Sciences, Prague) and Dr. Zdenek Lansky (Institute of Biotechnology, Czech Academy of Sciences, Prague) has uncovered a new mechanism of the crosstalk between microtubules and actin cytoskeleton during cell division and revealed unique characteristics of the previously unexplored protein FAM110A.

Mitochondria Influence the Ability of Adult Cardiac Cells to Multiply

Whether forcing adult cardiomyocytes to reverse from the oxidative phosphorylation phenotype to the glycolysis phenotype would also restore their mitotic ability.

Researchers Identify Molecular Stop Signal in Cell Division Monitoring

Every second, many million cells divide throughout the body. During nuclear division (mitosis), the genetic material must be divided correctly and fully amongst daughter cells; faults in this process can result in improper development or genetic diseases, and many cancer cells have an uneven number of chromosomes.

Exploring the Evolution of Mitosis: Lessons from Close Relatives of Fungi and Animals

Cell division is one of the most fundamental processes of life. From bacteria to blue whales, every living being on Earth relies on cell division for growth, reproduction, and species survival.

New Insights Into Centromere Structure: Two Subdomains Revealed

Researchers from the Kops group in collaboration with researchers from the University of Edinburgh, made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides.

UC San Diego Scientists Uncover Mechanism Behind Mitosis Timing

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from one parent cell to the next generation of two daughter cells.

Study unveils how our cells outsmart invaders without turning against us

The human immune system is a sophisticated network of cells and proteins created to defend against dangerous infections, and cells continuously repel invaders in a microscopic war raging inside human bodies.

The Exclusome, A New Mammalian "Container"

We speak to Dr. Ruth Kroschewski about new research that details the existence of an 'exclusome', a cytoplasmic container that appears to explain where extra-chromosomal DNA goes once it is in a cell.

The Role of the Golgi Apparatus in the Development of Postnatal Neurons

Neurons are the cells that constitute brain circuits and employ chemicals and electricity to receive and transmit information that allows the body to perform anything from thinking to sensing to movement.

Study discovers the ability of certain blood immune cells to proliferate

The ability of a cell to divide, to proliferate, is essential for life and gives rise to the formation of complex organisms from a single cell.

Researchers show how the production of different macromolecules peaks at different times

Textbooks will tell you that in dividing cells, the production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level.

Study elucidates the structure of centromeric region in chicken cells

The genetic material inside cells is organized into structures called chromosomes. The centromere is essential for the correct division of the chromosomes via interaction with spindle microtubules when cells divide and grow.
