New research by scientists at the University of Exeter has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide - a finding with potential links to the underlying causes of many cancers. The study, published today in Developmental Cell, describes a number of routes to the formation of a microtubule spindle – the tracks along which DNA moves when a cell divides in order to make two genetically identical cells. In order to understand the...

The duplication of cellular contents and their distribution to two daughter cells during cell division are amongst the most fundamental features of all life on earth. How cell division occurs and is coordinated with organismal development is a subject of intense research interest, as is how this process malfunctions in the development of tumors. Alex Dammermann and his team from the Max F. Perutz Laboratories (MFPL) of the University of Vienna and the Medical University of Vienna, together...

The Nek9 protein is required for chromosomes to separate into two identical groups. Nek9 exerts its action between two molecules of interest for the pharmaceutical industry as anti-tumoral agents, and for which inhibitors are already in advanced stages of clinical trials. Nek9 could be added to the list of candidates. A study by the Institute for Research in Biomedicine (IRB Barcelona) and the Center for Genomic Regulation (acronym in Catalan CRG) highlights the protein Nek9 as a...

Discovery at UCSF and Stowers Institute Shows Worm Regenerates Without Centrosome, a Structure Long Thought Necessary for Cell Division A tiny, freshwater flatworm found in ponds and rivers around the world that has long intrigued scientists for its remarkable ability to regenerate has now added a new wrinkle to biology. Reporting in the journal Science today, researchers at the University of California, San Francisco (UCSF) and the Stowers Institute for Medical Research in Kansas City,...

Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack centrosomes, cellular structures that organize the network of microtubules that pulls chromosomes apart during cell division. The flatworms' unique and unexpected characteristic, detailed in the Jan. 5, 2012 issue of Science Express, not only allowed lead author Juliette Azimzadeh,...

Stowers researchers gain new insight into the chromosome separation process Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells. Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the...

Discovery points to a potential co-contributor to cilia-related diseases Researchers at the University of Massachusetts Medical School have described a previously unknown role for the cilia protein IFT88 in mitosis, the process by which a dividing cell separates its chromosomes containing the cell's DNA into two identical sets of new daughter cells. Published in advance online by Nature Cell Biology, this newly discovered function for IFT88 suggests a possible alternative or contributory...

Teams from UK and Germany publish research in Nature Cell Biology New research that provides potential for exciting new approaches to targeting diseases such as cancer has been announced by an international team of academics. They have also announced the potential for more targeted treatments following their identification of proteins that play a vital role in the life of a human cell. The research teams from Germany and the UK have published their work in the Advance Online Publication on...

Researchers at the Carnegie Institution for Science, with colleagues at the Nara Institute of Science and Technology, observed for the first time a fundamental process of cellular organization in living plant cells: the birth of microtubules by studying recruitment and activity of individual protein complexes that create the cellular protein network known as the microtubule cytoskeleton"”the scaffolding that provides structure and ultimately form and shape to the cell. These fundamental...

When searching for long-lost treasure, sometimes all you need is a good flashlight. Such a "flashlight," developed at the Marine Biological Laboratory's (MBL) Josephine Bay Paul Center, has been used to illuminate a long-neglected cellular component "“ the nucleolinus "“ and confirm its role in cell division. MBL scientists Mark Alliegro and Mary Anne Alliegro, and MBL visiting investigator Jonathan Henry of University of Illinois, Urbana, present their discoveries regarding the...
