Protein kinase A activated in the nucleus as well as the cytoplasm

Using a new tool allowing proteins in a living cell to be manipulated in real time, researchers at Johns Hopkins have stumbled across the answer to a longstanding debate about where and how a certain protein is turned on in the cell. Reporting in the February 2012 issue of Nature Chemical Biology, scientists show that protein kinase A is also activated in the nucleus rather than inside the cell’s body, a challenge to traditional beliefs.

New type of micromachine can penetrate tissue and overcome cellular barriers

Microscopically small submarines that can swim through our blood to clear out clogged arteries or destroy malignant tumors. This concept may sound utopian, but it isn’t. Various micro- and nanomachines have in fact already been developed.

Scientists discover new flu-fighting role for IL-15 protein

University of Georgia scientists have discovered a new flu-fighting role for a well-known component of the immune system. Kimberly Klonowski, assistant professor of cellular biology in the UGA Franklin College of Arts and Sciences, and her colleagues found that administering a cell-signaling protein known as IL-15 to mice infected with influenza reduces their peak viral load by nearly three times.

Swine flu vaccination programme a success in Scotland

The H1N1 (“Swine flu”) vaccination programme introduced in Scotland in October 2009 had a positive effect in reducing the number of hospital admissions and deaths as a result of H1N1 infection, according to an Article published Online First in The Lancet Infectious Diseases. The study was funded by the National Institute for Health Research Health Technology Assessment (NIHR HTA) programme.

Ten young researchers named Pew Latin American Fellows in the Biomedical Sciences

Ten young researchers were named Pew Latin American Fellows in the Biomedical Sciences today by The Pew Charitable Trusts. For these scientists, who have dedicated their careers to finding solutions for some of the world's most troubling health problems, this fellowship will provide support that will further their research, enable them to work with colleagues in the United States, and increase scientific knowledge throughout their home region.

Paper spotlights unique developmental strategy undertaken by all mammals

Ask the average person the street how the brain develops, and they'll likely tell you that the brain's wiring is built as newborns first begin to experience the world. With more experience, those connections are strengthened, and new branches are built as they learn and grow. A new study conducted in a Harvard lab, however, suggests that just the opposite is true.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.

Neural protein plays two opposing roles

A protein produced by the central nervous system’s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Molecule that starts DNA repairs also halts them

Repairing DNA breaks can save a cell's life - but shutting off the repair machinery can be just as critical. How cells accomplish this feat was unknown. However, new research by Johns Hopkins scientists, published in the Feb. 22 issue of Nature, suggests that shutting down the repair machinery relies heavily on the same molecule used to start repair in the first place.

Mitotic spindle may be more complex than previously thought

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences.

P-bodies have a much broader role in controlling the activities of the cell than previously thought

Cells can reuse the chemical messengers that carry genetic information to the machinery that makes proteins. Sometimes cells shuttle the messengers to storage and later reactivate them to make proteins, according to new research.

Mod5 yeast prion contributes to cell survival under environmental stress

One of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in Science. Researchers at the RIKEN Brain Science Institute show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to drug resistance and cellular adaptation. Their discovery of a yeast prion with these properties demonstrates the active role of the prion conversion in cellular fitness adaptation, providing new insights into the potentially broader function of prions in living organisms.
