'Shuttling' protein possibly key to resilience of cancer cells
Researchers at Purdue University have discovered a molecular mechanism that may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment and that also may be involved in Alzheimer's and heart disease.   view more (2006-03-08)

Cloned mice created from fully differentiated cells, a milestone in cloning research
New research dismisses the notion that adult stem cells are necessary for successful animal cloning, proving instead that cells that have completely evolved to a specific type not only can be used for cloning purposes, but they may be a better and more efficient starting point.   view more (2006-10-02)

Ocean 'dead zones' trigger sex changes in fish, posing extinction threat
Oxygen depletion in the world's oceans, primarily caused by agricultural run-off and pollution, could spark the development of far more male fish than female, thereby threatening some species with extinction.   view more (2006-03-30)

Growth factor protects brain against damage from stroke
A naturally occurring growth factor called neuregulin-1 protects brain cells from damage resulting from stroke, according to an animal study conducted by researchers at Morehouse School of Medicine (MSM) and the Atlanta-based Center for Behavioral Neuroscience (CBN).   view more (2005-12-14)

U of MN researchers identify new cord blood stem cell
Researchers at the University of Minnesota Medical School have discovered a new population of cells in human umbilical cord blood that have properties of primitive stem cells.   view more (2006-02-14)

Little known DNA repair enzyme may be a tumor suppressor gene
The DNA in our cells is constantly being bombarded by environmental, chemical and cellular insults. Fortunately, our cells contain many enzymes devoted strictly to detecting and repairing any damage caused by these insults.   view more (2006-01-04)

Researchers identify major source of muscle repair cells
In a surprising discovery with implications for treating muscular dystrophy, researchers at the University of Utah School of Medicine and other institutions have identified a major source of origin for two groups of adult cells that regulate muscle repair.   view more (2006-01-30)

K-State researchers study gene regulation in insects
Susan Brown, an associate professor of biology at Kansas State University, is interested in how evolution generates so much diversity in insects shapes and forms.   view more (2006-04-28)

Protein's potential as a regulator of brain activity discovered
UC Irvine researchers have found that a protein best known for building connections between nerve cells and muscle also plays a role in controlling brain cell activity.   view more (2006-04-21)

How to design a cancer-killing virus
One new way to treat individuals with cancer that is being developed is the use of viruses that infect and kill cancer cells while leaving normal cells unharmed.   view more (2007-10-26)

Dengue Virus Reveals Its Circular Secret
The first step in the transmission of mosquito-borne viruses is no mystery: it's the pesky insect's bite that allows the virus to enter its victim's bloodstream. But for some of the most dangerous insect-borne viruses, details of what happens next have been unclear.   view more (2006-08-02)

Stem cells can repair torn tendons or ligaments
Weekend athletes who overexert themselves running or playing basketball may one day reap the benefits of research at the Hebrew University of Jerusalem that shows that adult stem cells can be used to make new tendon or ligament tissue.   view more (2006-04-04)

IU School of Medicine scientists testing stem cells for peripheral artery disease
Indiana University School of Medicine scientists have begun a unique clinical trial using stem cell injections as a treatment that could offer hope to tens of thousands of people who face sores, ulcers and even amputations due to severe peripheral artery disease.   view more (2006-02-10)

Diabetes research yielding breakthrough success
Freedom from insulin injections and the myriad of health problems related to type 1 diabetes is closer to becoming reality.   view more (2006-03-17)

Rockefeller researchers show evidence of asymmetric cell division in mammalian skin
It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin.   view more (2005-08-17)

Antibiotics may not be enough to stop recurrent gastric lymphoma caused by Helicobacter pylori
Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.   view more (2005-08-25)

Insects and mammals share common fat-building pathway, study suggests
When it comes to gaining fat, insects and mammals may have something in common, researchers report in the Jan. 11, 2006, Cell Metabolism.   view more (2006-01-11)

Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during... view more (2006-03-06)

Scientists crack genetic secrets of human egg
The human egg's ability to transform into a new life, or into new cells that may someday save lives, is well documented. The mystery lies in the mechanics-in how a single cell can transform so nimbly.   view more (2006-09-06)

UCLA researchers observe how the immune system recognizes and responds to cancer
Using positron emission tomography (PET) imaging, researchers at UCLA's Jonsson Cancer Center were able to observe-in real time-how the immune system initially recognizes cancer and mobilizes to fight the disease.   view more (2005-11-15)

Protein finding could lead to treatment for inflammatory diseases
A protein that undesirably shields a skin poxvirus from the immune system may become the key ingredient in a new topical treatment for inflammatory diseases.   view more (2006-01-12)

New U of T strategy will boost cord blood stem cells
A team of bioengineers led by the University of Toronto has discovered a way to increase the yield of stem cells from umbilical cord blood, to an extent which could broaden therapeutic use of these cells.   view more (2005-10-19)

Cancer cell communication exposed
The discovery, by scientists at Monash University and the Sloan Kettering Cancer Centre in New York, of how communication between cancer cells is controlled has promised new treatment options for malignant tumours.   view more (2005-10-31)

Discarded placentas deliver researchers promising cells similar to embryonic stem cells
Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells.   view more (2005-08-08)

Potential heart benefit found in stem cells
