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...

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...

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...

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis? "People have been looking at these proteins and players in mitosis for decades, and no one ever...

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,...

Suppressing a newly identified and characterized protein involved in regulating cell division could be a novel strategy to fight certain cancers because it stops the malignant cells from dividing and causes them to die quickly, according to a study by researchers with UCLA's Jonsson Comprehensive Cancer Center. During the five-year study, designed to seek new targets for anti-cancer therapies, researchers discovered that depleting the protein, called STARD9, also helped the commonly used...

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...

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...
