NIH Study may advance understanding of how brain cell tubes are modified under normal and disease conditions In a new study, scientists at the National Institutes of Health took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways. They watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules. The results, published in Cell, answer long-standing questions about how TAT...

From far away, the top of a leaf looks like one seamless surface; however, up close, that smooth exterior is actually made up of a patchwork of cells in a variety of shapes and sizes. Interested in how these cells individually take on their own unique forms, Caltech biologist Elliot Meyerowitz, postdoctoral scholar Arun Sampathkumar, and colleagues sought to pinpoint the shape-controlling factors in pavement cells, which are puzzle-piece-shaped epithelial cells found on the leaves of...

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...

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...

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that members of an enzyme family found in humans and throughout the plant and animal kingdoms play a crucial role in regulating cell motility. Their findings suggest an entirely new strategy for treating conditions ranging from diabetic ulcers to metastatic cancer. David Sharp, Ph.D., associate professor of physiology & biophysics, was the senior author of the study, which was published in the March 6...

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...

BERKELEY, CA "“ Microtubules are active protein polymers critical to the structure and function of cells and the process of cell division. In a living cell their growing ends constantly elongate and retreat in a thrashing frenzy of polymerization and depolymerization, like the writhing snakes of Medusa's hair. Known prosaically as "dynamic instability," this ongoing rapid growth and shrinkage is key to the diverse workings of microtubules in the cell.  For the first time,...
