Centro Nacional de Investigaciones Oncologicas (CNIO) New mutations in cohesin proteins, which are closely associated with cell division, are very common in various types of cancers such as bladder cancer and melanoma Massive sequencing of cancer genomes brings to light new genes every day that could be involved in the process of tumour formation. A good example of this is cohesin, a ring-shaped protein complex that embraces DNA to control cell division. Just a few months ago, 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...

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...

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...

Stowers team reports genome-wide analysis of genes that drive cell division in a multicellular organism In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells. This process, called mitosis, is visually stunning to observe under a microscope. Equally stunning to cell biologists are the preparatory steps cells take to ensure that the process occurs safely....

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...

Physical Reason For Shape Of Metaphase Chromosome Discovered
2014-01-15 07:37:00

Universitat Autonoma de Barcelona This work gives a solution to a fundamental question in structural biology: Why do metaphase chromosomes have their characteristic elongated cylindrical shape? The proposed solution is consistent with the structure of metaphase chromatin and with the nanomechanical properties of chromatin and chromosomes. It is a research at the interface between biology (higher order chromatin structure) and physical sciences (supramolecular structures and nanomaterials)....

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...

Researchers at the Cell Cycle Research Group of the Bellvitge Institute of Biomedical Research (IDIBELL) led by Ethel Queralt have reported in the journal PLoS Genetics an article which delve into the regulator mechanisms of mitosis, a key stage of the cell-cycle for the correct transmission of genetic information from parents to sons. Cell-cycle Cells in all organisms grow and divide into two daughter cells by an ordered sequence of events called "cell cycle". Basically, the cells have...
