UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

Blocking Skp2 protein might inhibit glycolysis and treat breast cancer

HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in the May 25 issue of Cell.

UC Irvine immunologist to create new line of neural stem cells for MS

A UC Irvine immunologist will receive $4.8 million to create a new line of neural stem cells that can be used to treat multiple sclerosis.

UCSD scientists receive new CIRM grants to conduct stem cell-based research

Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer's disease.

Scientists show how hemizygous deletion can contribute to cancer

Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute to cancer.

City of Hope receives CIRM grant to develop T cell-based immunotherapy against glioma

City of Hope was granted a $5,217,004 early translational research award by the California Institute for Regenerative Medicine (CIRM) to support the development of a T cell-based immunotherapy that re-directs a patient's own immune response against glioma stem cells.

X-chromosome involved in development of bowel cancer

Scientists have shown for the first time that one of the sex chromosomes is involved in the development of a cancer that can afflict both genders, according to a Cancer Research UK-funded study in Nature Genetics.

New, more accurate test for paralytic shellfish poisons

For decades, U.S. fisheries have tested the algal toxin levels of shellfish caught for human consumption by processing a sample of the shellfish in a blender and injecting the resulting slurry into the abdomen of live mice, causing them to suffer seizures, paralysis, and death by suffocation.

Overactive BAALC gene found in people with acute leukemia

A small inherited change in DNA is largely responsible for overactivating a gene linked to poor treatment response in people with acute leukemia.

Special surface allows adult-derived stem cells to thrive and transform into multiple cell types

University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.

'Killer silk' can kill anthrax in minutes

The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes a simple, inexpensive dip-and-dry treatment can convert ordinary silk into a fabric that kills disease-causing bacteria - even the armor-coated spores of microbes like anthrax - in minutes.

Bacteria are key contributors to the cause of IBS, study confirms

An overgrowth of bacteria in the gut has been definitively linked to Irritable Bowel Syndrome in the results of a new Cedars-Sinai study which used cultures from the small intestine. This is the first study to use this "gold standard" method of connecting bacteria to the cause of the disease that affects an estimated 30 million people in the United States.

Immune system involved in removing Alzheimer's-causing substance in the brain

Recent work in mice suggested that the immune system is involved in removing beta-amyloid, the main Alzheimer's-causing substance in the brain. Researchers have now shown for the first time that this may apply in humans.

Brain can rewire even at an advanced age

"This study overturns decades-old beliefs that most of the brain is hard-wired before a critical period that ends when one is a young adult," said MPFI neuroscientist Marcel Oberlaender, PhD, first author on the paper.

BBSRC allocates £250M for strategic investment programmes

Minister for Universities and Science, David Willetts, will today announce substantial funding that will ensure the UK's bioscience research base remains globally competitive and at the forefront of meeting the grand challenges faced by society in the coming decades. The announcement will be made by the Minister during a visit to the Babraham Research Campus, near Cambridge, and highlighted again during a major speech at the University of East Anglia in Norwich.

Gene therapy can effectively treat ADA-deficient severe combined immunodeficiency

Severe combined immunodeficiency is defect in the immune system that results in a loss of the adaptive immune cells known as B cells and T cells. Mutations in several different genes can lead to the development of severe combined immunodeficiency, including mutation of the adenosine deaminase (ADA) gene. Traditional treatment options, such as enzyme replacement therapy, are of limited efficacy, but bone marrow transplant from a compatible donor leads to a better response.

University of Kentucky researcher receives $1.8M NIH grant to study CF

David Feola, a University of Kentucky College of Pharmacy faculty member in the Department of Pharmacy Practice and Science, received a five-year, $1.8 million grant from the National Institutes of Health (NIH) to continue his research investigating immune responses in the lungs that will potentially lead to the discovery of medical treatments for patients with cystic fibrosis and other chronic pulmonary inflammatory conditions.

Thioridazine drug successfully kills human cancer stem cells

A team of scientists at McMaster University has discovered a drug, thioridazine, successfully kills cancer stem cells in the human while avoiding the toxic side-effects of conventional cancer treatments.

New diagnostic approach for Lyme disease

George Mason University researchers can find out if a tick bite means Lyme disease well before the bite victim begins to show symptoms.

Researchers uncover series of biological events that implicate stem cells' surroundings

Stem cells are essential building blocks for all organisms, from plants to humans. They can divide and renew themselves throughout life, differentiating into the specialized tissues needed during development, as well as cells necessary to repair adult tissue.
