Protein that triggers plant cell division revealed by researchers
From the valves in a human heart to the quills on a porcupine to the petals on a summer lily, the living world is as varied as it is vast. For this to be possible, the cells that make up these living things must be just as varied. Parent cells must be able to divide in ways that create daughter ce...
Study may aid efforts to prevent uncontrolled cell division in cancer
Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have uncovered a remarkable property of the contractile ring, a structure required for cell division. Understanding how the contractile ring works to divide the cell may facilit...
Brain building: Study shows brain growth tied to cell division in mouse embryos
How your brain grows might come down to how your cells divide. In the April 6 issue of the Journal of Cell Biology ( JCB ), Lake and Sokol report that mouse protein Vangl2 controls the asymmetrical cell division
and developmental fate of progenitor neurons.
Vangl2 (aka Strabismus in flies) is...
New cell division mechanism discovered

mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online v...
LIAI launches new division to look at novel approaches to heart disease and inflammation
SAN DIEGO (September 30, 2008) While cholesterol-lowering drugs and new technologies have significantly advanced the nation's battle against heart disease, it continues to rank as the No. 1 killer of U.S. men and women. But if researchers at the La Jolla Institute for Allergy & Immunology (LIAI)...
Death, division or cancer? Newly discovered checkpoint process holds the line in cell division
Each day, a staggering number of cells perform a feat that still amazes researchers with its complexity: they divide to produce perfect replicas of each other. The process is called mitosis, and an inability to control it is one of the hallmarks of cancer.
Little is known about the biochemica...

Slicing chromosomes leads to new insights into cell division
ANN ARBOR, Mich.By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division.

New models question old assumptions about how many molecules it takes to control cell division
Blacksburg, Va. -- A single cell whether a yeast cell or one of your cells is exquisitely sensitive to its surroundings. It receives input signals, processes the information, makes decisions, and issues commands for making the proper response. As with any control system, noise errors, slip-ups,...
Scientists deconstruct cell division
Baltimore, MDThe last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells. In mitosis, the chromosomes condense and the nucleus breaks down. Fibrous structures called spindles form, w...
Proteins strangle cell during division
A Swedish research group, partly financed by NWO, has discovered a new mechanism for cell division
in a microorganism found in extremely hot and acidic conditions. The results of the research offer insights into evolution, but also into the functioning of the human body. The research has been rece...
Rong Li Lab probes mechanism of asymmetry in meiotic cell division
The Stowers Institute's Rong Li Lab has characterized a mechanism that allows for asymmetrical cell division
during meiosis in oocytes. By tracking chromosome movement in live mouse oocytes, the team discovered that chromosomes can recruit to their vicinity a protein called formin-2. This protein ...
A unique arrangement for egg cell division
Heidelberg, 09 August 2007 - Which genes are passed on from mother to child is decided very early on during the maturation of the egg cell in the ovary. In a cell division
process that is unique to egg cells, half of the chromosomes are eliminated from the egg before it is fertilised. Using a powe...
Rewind, please: Nature paper shows that cell division is reversible
Gary J. Gorbsky, Ph.D., a scientist with the Oklahoma Medical Research Foundation, has found a way to reverse the process of cell division.
The discovery could have important implications for the treatment of cancer, birth defects and numerous other diseases and disorders. Gorbsky's findings appe...
Genes involved in cell growth and cell division identified
A recent study shows that hundreds of genes contribute to cell growth and cell division. For the first time these genes, many of which are potential contributors to cancer, have been mapped in a single systematic study.
The group led by Professor Jussi Taipale (University of Helsinki and National...
Hunt for human genes involved in cell division under way
A systematic search through human genes has begun at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Working within the MitoCheck consortium that includes 10 other institutes throughout Europe, the EMBL scientists will silence all human genes, one-by-one, to find those invo...
Key mechanism in genetic inheritance during cell division identified
A key mechanism in the passing of genetic material from a parent cell to daughter cells appears to have been identified by a team of Berkeley researchers. Their study may explain how a complex of proteins, called kinetochores, can recognize and stay attached to microtubules, hollow fibers in the wa...
