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...

Scientists at the University of East Anglia have made a major advancement in understanding tissue development that has important implications for cancer. Findings published today in the Journal of Cell Science show how the protein EB2 is a key regulator of tube-like structures inside cells and critical for normal tissue development and function. The findings are an important step in the race to find cures for cancers including gut, breast and pancreatic cancer. Microtubules are...

Published in the Proceedings of the National Academy of Sciences, the Study by Erkan Tuzel and Scientists at UMass Amherst Provides New Insights into a Cellular System Whose Failure Can Lead to Neurodegenerative Diseases and Cancer. Worcester, MA (PRWEB) December 14, 2012 The interior of an animal cell is like a small city, with factories–called organelles–dedicated to manufacturing, energy production, waste processing, and other life functions. A network of intercellular...

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...

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...

High-powered microscopes reveal workings of the cell -- results could impact treatment of Down syndrome, lissencephaly (a brain formation disorder) or cancer Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell — and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process. The findings by the international team led by...

Quantitative research shows key organelle of cell division to be more complex than previously thought The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences (SEAS). The researchers used a femtosecond laser to slice through the strands of the organelle and then performed a mathematical analysis to infer the...

(Ivanhoe Newswire) A new study shows that a new drug, called epothilone D (EpoD) is preventing neurological damage and improving cognitive performance in a mouse model of Alzheimer's disease (AD). Investigators from the Perelman School of Medicine at the University of Pennsylvania, led by first author Bin Zhang, MD, PhD, senior research investigator, and senior author Kurt R. Brunden, PhD, Director of Drug Discovery at the Center for Neurodegenerative Disease Research (CNDR), administered...

Arbacia punctulata
2013-11-06 11:08:03

Arbacia punctulata is a species of Arbacia genus of purple-spined sea urchins. Its natural habitat is in the Western Atlantic Ocean. It can be found in shallow water from Massachusetts to Cuba and the Yucatan Peninsula, from Texas to Florida in the Gulf of Mexico, the coast from Panama to French Guiana and in the Lesser Antilles, normally on sandy, rocky, or shelly bottoms. It is omnivorous, consuming a wide variety of preys. It’s been shown that it is galactolipids, rather than...
