Visiopharm's new Virtual Double Staining (VDS) Ki67 module for breast is a novel, patented and now CE-marked diagnostic APP intended for automated tumor/stroma separation and computation of the Ki67 labelling index for the identified tumor cells. Hoersholm, Denmark (PRWEB) June 30, 2014 The Virtual Double Staining (VDS) Ki67 module for breast is a novel, patented and now CE-marked diagnostic APP intended for automated tumor/stroma separation and computation of the Ki67 labelling index...

Southwestern Medical Center A drug that blocks the action of the enzyme Cdk5 could substantially reduce brain damage if administered shortly after a stroke, UT Southwestern Medical Center research suggests. The findings, reported in the June 11 issue of the Journal of Neuroscience, determined in rodent models that aberrant Cdk5 activity causes nerve cell death during stroke. “If you inhibit Cdk5, then the vast majority of brain tissue stays alive without oxygen for up to one...

Finding could influence cancer care and regenerative medicine An international team led by researchers at UC Davis has shown that the cyclin B1/Cdk1 protein complex, which plays a key role in cell division, also boosts the mitochondrial activity to power that process. This is the first time the complex has been shown to perform both jobs. This newfound ability could make cyclin B1/Cdk1 an excellent target to control cellular energy production, potentially advancing cancer care and...

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....

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...

Cyclin D1 controls cell cycle progression and microRNA biogenesis through Dicer -- a new mechanism promoting breast cancer Cyclin D1, a protein that helps push a replicating cell through the cell cycle also mediates the processing and generation of mature microRNA (miRNA), according to new research publishing November 29 in Nature Communications. The research suggests that a protein strongly implicated in human cancer also governs the non-protein-coding genome. The non-coding genome,...

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...

In a study to be published in the journal Nature, two Dartmouth researchers have found that the protein cyclin A plays an important but previously unknown role in the cell division process, acting as a master controller to ensure the faithful segregation of chromosomes during cell division. Cell division is the process in which cells reproduce by splitting into two identical copies. This process happens trillions of times in an average person's lifetime. To generate two identical copies,...
