New research sheds light on pluripotency

New research at the Hebrew University of Jerusalem sheds light on pluripotency-the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells.

Helmholtz-Zentrum Geesthacht to establish Virtual Institute

In collaboration with the university hospitals of Hamburg, Hannover and Graz, as well as further partners, the Helmholtz-Zentrum Geesthacht will establish a Virtual Institute, whose focus will be set on degradable magnesium implants. One aim of the research association coordinated from Geesthacht is to develop first prototypes of orthopedic implants.

Cadherin-catenin-actin structure exerts force inside and between cells in living tissues

If you place certain types of living cells on a microscope slide, the cells will inch across the glass, find their neighbors, and assemble themselves into a simple, if primitive tissue. A new study at Stanford University may help explain this phenomenon, and then some, about the mechanical structure and behavior of complex living organisms.

Novel molecular mechanism responsible for most important symptom of major depression

Stanford University School of Medicine scientists have laid bare a novel molecular mechanism responsible for the most important symptom of major depression: anhedonia, the loss of the ability to experience pleasure.

Blocking a fundamental process deep within cancer cells can selectively kill them

Investigators reporting in the July issue of the Cell Press journal Cancer Cell have found that blocking a fundamental process deep within cancer cells can selectively kill them and spare normal cells.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

Study sheds light on the assembly of ribosome

Scientists from the Florida campus of The Scripps Research Institute have identified a series of intricate biochemical steps that lead to the successful production of proteins, the basic working units of any cell.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Early brain changes predict chances of developing chronic pain

When people have similar injuries, why do some end up with chronic pain while others recover and are pain free? The first longitudinal brain imaging study to track participants with a new back injury has found the chronic pain is all in their heads -- quite literally.

Vaccine for nicotine addiction developed

Researchers at Weill Cornell Medical College have developed and successfully tested in mice an innovative vaccine to treat nicotine addiction.

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.

Gene transfer technique eliminates specific neural circuit linked to Parkinson's disease

In the brains of humans and non-human primates, over 100 billion nerve cells build up complicated neural circuits and produce higher brain functions. When an attempt is made to perform gene therapy for neurological diseases like Parkinson's disease, it is necessary to specify a responsible neural circuit out of many complicated circuits.

Deep brain stimulation reduces binge eating

Deep brain stimulation reduces binge eating in mice, suggesting that this surgery, which is approved for treatment of certain neurologic and psychiatric disorders, may also be an effective therapy for obesity. Presentation of the results will take place Sunday at The Endocrine Society's 94th Annual Meeting in Houston.

Scientists identify novel animal reservoir for tick-borne diseases

A team of scientists at Washington University in St. Louis has been keeping a wary eye on emerging tick-borne diseases in Missouri for the past dozen years, and they have just nailed down another part of the story.

New signal transduction pathway might be fruitful target for cancer drugs

Researchers at the University of California, San Diego School of Medicine have uncovered a new signal transduction pathway specifically devoted to the regulation of alternative RNA splicing, a process that allows a single gene to produce or code multiple types of protein variants. The discovery, published in the June 27, 2012 issue of Molecular Cell, suggests the new pathway might be a fruitful target for new cancer drugs.

FOXO3a transcription factor actually promotes growth of anaplastic thyroid cancer

A molecule widely believed to fight many forms of cancer actually helps deadly thyroid tumors grow, and cancer therapies now being tested in humans might boost the activity of this newly revealed bad guy, researchers at Mayo Clinic in Florida say.

Deep brain stimulation remains an effective treatment for Parkinson's

A "brain pacemaker" called deep brain stimulation (DBS) remains an effective treatment for Parkinson's disease for at least three years, according to a study in the June 2010 online issue of Neurology, the medical journal of the American Academy of Neurology.
