University of Minnesota Academic Health Center New structures discovered within cilia show a relationship between certain proteins and juvenile myoclonic epilepsy. The discovery, made at the University of Minnesota, was named paper of the week in the Journal of Biological Chemistry, and sheds new light on the microstructure of cilia. Cilia are microscopic, hair-like structures occurring in large numbers on the surface of some of the body's cells and are involved in movement and...

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...

Ecole Polytechnique Fédérale de Lausanne Like our own bodies, cells have their own skeletons called 'cytoskeletons' and are made of proteins instead of bones. These network-like structures maintain the cell's shape, provide mechanical support, and are involved in critical processes of the cell's lifecycle. The cytoskeleton is an object of intense scientific and medical research, which often requires being able to observe it directly in cells. Ideally, this would involve...

Berkeley Lab Berkeley Lab Researchers Take an Atomic-Scale Look at Key Cellular Protein A pathway to the design of even more effective versions of the powerful anti-cancer drug Taxol has been opened with the most detailed look ever at the assembly and disassembly of microtubules, tiny fibers of tubulin protein that form the cytoskeletons of living cells and play a crucial role in mitosis. Through a combination of high-resolution cryo-electron microscopy (cryo-EM) and new methodology for...

Malaria Pathogen's Cellular Skeleton Under A Super-microscope

Helmholtz Centre for Infection Research This news release is available in German. The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different versions of this protein in the parasite in high detail. Their results, published in the scientific journal...

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...

Researchers from Warwick Medical School have discovered the key role of a protein in shutting down endocytosis during mitosis, answering a question that has evaded scientists for half a century. The study, published today in the journal eLife, is the first to outline the role of actin, a protein, in shutting down clathrin-dependent endocytosis during mitosis. Endocytosis is the process by which cells absorb molecules that are too large to pass through the plasma membrane, such as...

Researchers from Warwick Medical School have discovered a critical point of failure in the microscopic transport system that operates inside every cell in the human body. The study, published today in Nature Communications, explains how this tiny 'railway' system is a key target for cancer drugs and, as such, how this new discovery reveals how better drugs might be made. The tracks of this so called 'railway' are tiny tubes, called microtubules, 1000 times thinner than a human hair. The...

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...
