Tokyo, Nov 29, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have identified key information to help explain the formation of the "spindle apparatus", a structure required for cell division. Their findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures.Organisms are composed of a variety of structures including muscles, internal organs, and brains, all of which are created through a process known as...

Tokyo, Nov 25, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have for the first time directly observed the "molecular motor", called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.A human being begins as...

In a study to be published in the journal Nature, two Dartmouth researchers have found that the protein cyclin A plays an important but previously unknown role in the cell division process, acting as a master controller to ensure the faithful segregation of chromosomes during cell division. Cell division is the process in which cells reproduce by splitting into two identical copies. This process happens trillions of times in an average person's lifetime. To generate two identical copies,...

Researchers at Warwick Medical School have identified the key role played by a team of proteins in the process of mitosis. Working out how to control them may give scientists a way to destroy cancerous cells. The study, published in The Journal of Cell Biology, highlights the role of a newly identified team of proteins, TACC3-ch-TOG-clathrin, in forming inter-microtubule bridges that stabilize the kinetochore fibers (K-fibers) used in mitosis. When a cell divides, it produces a mitotic...

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...

Findings of disrupted micronuclei may prove to be a valuable tool for detecting cancer Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis. In a new study, published on July 3 in Cell, a team of scientists at the Salk Institute...

Researchers at the University of Geneva, Switzerland, demonstrate that the receptors that bind the toxin of this bacterium control how cell division is oriented Anthrax uses a receptor on the surface of cells to inject its lethal toxins. However, the physiological function of this receptor, named Anthrax Toxin Receptor 2a (Antxr2a), remained unknown until now. A team led by Marcos Gonzalez-Gaitan, a professor at the University of Geneva (UNIGE), Switzerland, in collaboration with Gisou van...

Biologists have identified a new molecular player in asymmetric cell division, a protein named She1 whose role wasn't known before - This is important for self-renewal of stem cells and ensures that daughter cells have different fates and functions Recently biologists at the University of Massachusetts Amherst led by Wei-lih Lee have identified a new molecular player in asymmetric cell division, a regulatory protein named She1 whose role in chromosome- and spindle positioning wasn't known...
