Discovery of new signal pathway important to diabetes research
Scientists at Karolinska Institutet in Sweden and Miami University have discovered that cells in the pancreas cooperate - signal - in a way hitherto unknown. The discovery can eventually be of significance to the treatment of diabetes.   view more (2008-06-05)

Mammalian neurogenesis breaks into the most static brain region
ifteen years ago, the discovery of adult neurogenesis (the production of new neurons) in the highly static, non-renewable mammalian brain was a breakthrough in neuroscience.   view more (2008-06-04)

U of M Sets Course For Cure of Fatal Childhood Skin Disease
Physicians at the University of Minnesota and University of Minnesota Children's Hospital, Fairview have set the path to a cure for a young boy's fatal genetic skin disease, recessive dystrophic epidermolysis bullosa (RDEB), by using a cord blood and bone marrow transplant. Nate Liao, a... view more (2008-06-04)

Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of... view more (2008-06-04)

Mouse model developed at UT Southwestern mimics hyperglycemia, aids in diabetes research
UT Southwestern Medical Center researchers have genetically engineered a laboratory mouse in which pancreatic beta cells can regenerate after being induced to die. The new animal model's regenerative ability may provide future insights into improved treatments of diabetes, which affects millions of... view more (2008-06-02)

Brain cells help neighboring nerves regenerate
Researchers have uncovered a completely unexpected way that the brain repairs nerve damage, wherein cells known as astrocytes deliver a protective protein to nearby neurons.   view more (2008-05-28)

Regulatory B cells exist -- and pack a punch
Researchers at Duke University Medical Center have uncovered definitive evidence that a small but potent subset of immune system B cells is able to regulate inflammation.   view more (2008-05-28)

Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells.   view more (2008-05-28)

Origin of cells for connective tissues of skull and face challenged
With improved resolution, tissue-specific molecular markers and precise timing, University of Oregon biologist James A. Weston and colleagues have possibly overturned a long-standing assumption about the origin of embryonic cells that give rise to connective and skeletal tissues that form the base... view more (2008-05-27)

UCLA researchers identify leukemia stem cells
Stem cell researchers at UCLA have identified a type of leukemia stem cell and uncovered the molecular and genetic mechanisms that cause a normal blood stem cells to become cancerous.   view more (2008-05-27)

Researchers find roadmap to next-generation cancer therapies
Pinpointing new targets for cancer treatments is as difficult as finding a needle in a haystack, yet a University of Rochester team has discovered an entire novel class of genes they believe will lead to a greater understanding of cancer cell function and the next generation of effective and less... view more (2008-05-27)

Protein that provides innate defense against HIV could lead to new treatments
By identifying a protein that restricts the release of HIV-1 virus from human cells, scientists believe they may be closer to identifying new approaches to treatment. The research is published in the advance online edition of Nature Medicine.   view more (2008-05-27)

Dual functions of gene revealed, for better and for worse
Researchers at WEHI have pinpointed the function of a potent cancer gene. The gene, known as "ERG", has long been associated with a range of human malignancies, including leukemia and sarcoma. American scientists showed in 2005 that ERG is mutated in more than half of all prostate... view more (2008-05-27)

Researchers demonstrate 'avalanche effect' in solar cells
Researchers at TU Delft and the FOM Foundation for Fundamental Research on Matter have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.   view more (2008-05-27)

OHSU Discovery May Lead to Early Cancer Detection
OHSU pancreatic cancer expert Brett Sheppard, M.D., and colleagues in the OHSU Oregon Stem Cell Center, have developed antibodies that recognize pancreatic cancer; Sheppard is presenting these findings this week during Digestive Disease Week in San Diego.   view more (2008-05-23)

USC stem cell study sheds new light on cell mechanism
Research from the University of Southern California (USC) has discovered a new mechanism to allow embryonic stem cells to divide indefinitely and remain undifferentiated.   view more (2008-05-22)

Many paths, few destinations: How stem cells decide what they'll be
How does a stem cell decide what specialized identity to adopt - or simply to remain a stem cell? A new study suggests that the conventional view, which assumes that cells are "instructed" to progress along prescribed signaling pathways, is too simplistic.   view more (2008-05-22)

Protein key to neuro-regeneration
Researchers at the Peninsula Medical School in the South West of England, University College London, the San Raffaele Scientific Institute in Milan and Cancer Research UK, have for the first time identified a protein that is key to the regeneration of damage in the peripheral nervous system and... view more (2008-05-21)

A potential route for human tumor gene therapy
The type 1 Na+/H+ exchanger (NHE1) is a transmembrane protein found in all eukaryotic cells. One of its functions is to evacuate excessive H+ in the cytoplasm by means of Na+-H+ exchange, resulting in stable intracellular pH value.   view more (2008-05-21)

Bone drug could help prevent the spread of breast cancer
Maintaining bone density could be a key to decreasing the spread of cancer in women with locally advanced breast cancer, according to research at Washington University School of Medicine in St. Louis.   view more (2008-05-19)

New Mount Sinai research tracks effects of addictive drugs on brain
Mount Sinai researchers may have unlocked the key to better understanding the effect addictive drugs have on the human brain.   view more (2008-05-16)

Vitamin D protects cells from stress that can lead to cancer
By inducing a specific gene to increase expression of a key enzyme, vitamin D protects healthy prostate cells from the damage and injuries that can lead to cancer, University of Rochester Medical Center researchers report.   view more (2008-05-14)

How embryonic stem cells develop into tissue-specific cells demonstrated
While it has long been known that embryonic stem cells have the ability to develop into any kind of tissue-specific cells, the exact mechanism as to how this occurs has heretofore not been demonstrated.   view more (2008-05-13)

Arsenic-based therapy shown to help eradicate leukemia-initiating cells
In both leukemia and solid tumors, there exists among the multitude of warrior cancer cells a small subgroup that work undercover, patiently lying in wait to launch their attacks.   view more (2008-05-13)
