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...

A recent study undertaken by investigators at five research centres, amongst which is the CSIC-University of the Basque Country Biophysics Unit, provides new clues for the understanding of the "Ëœcell suicide' process. The research was published in the latest issue of the prestigious Cell journal. Our bodies daily eliminate in a controlled manner more than 100 million defective cells, by means of a procedure known as "Ëœcell suicide' or apoptosis. This is a highly...

While scientists have spent the past 40 years describing the intricate series of events that occur when one mammalian cell divides into two, they still haven't agreed on how the process begins. There are two seemingly contradictory theories, which now may be reconciled by a third theory being proposed by Duke University bioengineer Lingchong You. These findings could provide insights into the initiation of disease, such as cancer, which is marked by uncontrolled cell proliferation. During...

Like some people, cells eat when they are under pressure"”but they consume parts of themselves. A multi-function protein helps control this form of cannibalism, according to a study in the September 6 issue of the Journal of Cell Biology (www.jcb.org). Cells often respond to hunger or stress by digesting some of their contents. The process, known as autophagy, helps free nutrients and clean up cytoplasmic trash such as worn-out organelles and misshapen proteins. A team led by...

Stem cells might be thought of as trunks in the tree of life. All multi-cellular organisms have them, and they can turn into a dazzling variety other cells"”kidney, brain, heart or skin, for example. One class, pluripotent stem cells, has the capacity to turn into virtually any cell type in the body, making them a focal point in the development of cell therapies, the conquering of age-old diseases or even regrowing defective body parts. Now, a research team at the University of Georgia...

Defining of novel mechanism informs understanding of cancer, aging physiology University of Pennsylvania School of Medicine  researchers have described a previously unknown biological mechanism in cells that prevents them from cannibalizing themselves for fuel. The mechanism involves the fuel used by cells under normal conditions and relies on an ongoing transfer of calcium between two cell components via an ion channel. Without this transfer, cells start consuming themselves as a way of...

WASHINGTON, July 20 /PRNewswire-USNewswire/ -- A major discovery, led by researchers from The George Washington University Medical Center, promises to revolutionize the way scientists think about key aspects of cellular lifecycle and offers a new avenue for cancer researchers to explore in their quest to one day slow down the progression of cancer. The discovery, reported in the article "Arpc 1b, a centrosomal protein, is both an activator and substrate of Aurora A," furthers the science...

Residual "memory" of the tissue of origin makes it harder to turn them into other cell types BOSTON, July 19 /PRNewswire-USNewswire/ -- Adult cells that have been reprogrammed into induced pluripotent stem cells (iPS cells) do not completely let go of their past, perhaps limiting their ability to function as a less controversial alternative to embryonic stem cells for basic research and cell replacement therapies, according to researchers at Children's Hospital Boston, John Hopkins...

Researchers reveal that JNK, a protein long known to help cells respond to stress, also controls cell cycle Put simply, a tumor is the result of out-of-control cell growth. To assure that the cell cycle "“ the cell's process of duplicating itself to make more cells "“ goes smoothly, a large network of proteins tells other proteins what to do and when to do it. When any of these layers of protein regulation fail, cell growth can get out of hand. A new study led by Ze'ev Ronai,...

Researchers funded by the Medical Research Council (MRC) have discovered for the first time that two proteins called Mahjong and Lgl could be star players in helping to identify how the body's own cells fight back against cancer cells. This discovery, publishing today in the online, open-access journal PLoS Biology, could lead to future treatments to make our healthy cells better-equipped to attack cancer cells, an entirely new concept for cancer research. The team, who undertook the research...

Cell (journal)
2012-06-04 14:15:36

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...
