Ribonucleoprotein granules exit the nucleus via a budding mechanism akin to herpes-type viruses The movement of genetic materials, such as RNA and ribosomes, from the nucleus to the cytoplasm is a critical component in a cell's ability to make the proteins necessary for essential biological functions. Until now, it was believed the nuclear pore complex was the sole pathway between the cell nucleus and cytoplasm for these materials. New evidence published in Cell by Vivian Budnik, PhD,...

Scientists from the Medical Research Council (MRC) Institute of Genetics and Molecular Medicine (IGMM) at the University of Edinburgh have discovered an enzyme that corrects the most common mistake in mammalian DNA. The mistake is the inclusion of individual bits of RNA within the DNA sequence, which the researchers found occurs more than a million times in each cell as it divides. The findings, published in Cell, suggest the RNase H2 enzyme is central to an important DNA repair mechanism...

Journal of Biological Chemistry: Mechanism of bacterial transport system published In order to interact with the environment, bacteria secrete a whole arsenal of proteins. Researchers have now found how one of the transportation systems used for this purpose — the type VI secretion system — works for the single-celled organism Agrobacterium tumefaciens. They have identified the relevant transport proteins and their energy suppliers. With colleagues at the Academia Sinica in...

Tiny organelles called primary cilia hold the key to combat inflammation Scientists from Queen Mary, University of London have found a new therapeutic target to combat inflammation. The research, published in the journal Cellular and Molecular Life Sciences, revealed tiny organelles called primary cilia are important for regulating inflammation. The findings could lead to potential therapies for millions of people who suffer from arthritis. Dr Martin Knight who led the research at...

Stem Cells Poised To Self-Destruct For The Good Of The Embryo
2012-05-03 10:58:28

Embryonic stem cells – those revered cells that give rise to every cell type in the body – just got another badge of honor. If they suffer damage that makes them a threat to the developing embryo, they swiftly fall on their swords for the greater good, according to a study published online May 3, 2012 in the journal Molecular Cell. The finding offers a new glimpse into the private lives of stem cells that could help scientists use them to grow new neurons or other cells to...

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...

Berkeley Lab scientists demonstrate the promise of synchrotron infrared spectroscopy of living cells for medical applications Knowing how a living cell works means knowing how the chemistry inside the cell changes as the functions of the cell change. Protein phosphorylation, for example, controls everything from cell proliferation to differentiation to metabolism to signaling, and even programmed cell death (apoptosis), in cells from bacteria to humans. It´s a chemical process that...

St. Jude Children's Research Hospital discovery that a protein vital for cell survival and immune balance has another form with a different function could yield additional cancer treatment strategy Research led by St. Jude Children's Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein's work. Nearly 20 years after MCL1 was discovered, scientists have...

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 &...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
