Researchers step closer to cure for common childhood cancer

Acute lymphoblastic leukemia (ALL) is a malignant disease caused by the abnormal growth and development of white blood cells (WBC) in the bone marrow and blood. ALL is the most common cancer occurring in children with an annual rate of approximately 30 to 40 new cases per million.

Researchers find mutations in a multifunctional protein cause Parkinsonism

A team of researchers at Mayo Clinic in Jacksonville, Fla. and colleagues in Canada and Germany have discovered a gene and six mutations of it that cause symptoms associated with Parkinson's disease and other neurodegenerative disorders.

70% of cases of spina bifida are preventable by folic-acid supplementation

A seminar in this week’s issue of THE LANCET discusses the causes, symptoms, and treatments relating to spina bifida, and reinforces an important public-health message for women about to become pregnant

Sex genes of infectious fungus closely resemble human Y chromosome

Fungi and animals, including humans, have a lot in common when it comes to the arrangement of genes that determine their sex, according to new work by Howard Hughes Medical Institute geneticists at the Duke University Medical Center.

Search for genetic key to corneal disease

A new federal grant focusing on painful inherited visual disorders that scar the cornea will allow researchers to narrow the genetic cause of one type of corneal dystrophy and to offer improved diagnosis of this family of diseases.

Researchers find two locations in the human genome that may harbor genes that increase the risk of Alzheimer’s disease

Researchers at Columbia University Medical Center have found two locations in the human genome that may harbor genes that increase the risk of Alzheimer’s disease. If confirmed, they will be the first genes linked to Alzheimer’s disease since ApoE4 was discovered in 1993.

Improved risk classification for patients with acute lymphoblastic leukemia offers hope for eliminating irradiation

Improved risk classification for patients with acute lymphoblastic leukemia (ALL), coupled with more intensive intrathecal chemotherapy for high risk patients and the use of a drug called dexamethasone, could one day permit physicians to omit irradiation as a part of routine treatment.

Scientists decode the genome sequence of Cryptosporidium hominis, one of the most common causes of waterborne diseases in humans

A team of scientists at Tufts University School of Veterinary Medicine has helped decode the genome sequence of Cryptosporidium hominis, an insidious parasite identified as one of the most common causes of waterborne diseases in humans and classified by the Centers for Disease Control and Prevention as a potential bioterrorist agent.

New insight into the role of the breast cancer gene known as BRCA2

Researchers at the Medical Research Council (MRC) Cancer Cell Unit, Cambridge have gained an important new insight into the role of the breast cancer gene known as BRCA2.

Australian platypus research has implications for understanding the evolution of human sex determination

The mystery surrounding sex determination of the unique Australian platypus has yielded a surprising secret: it has 10 sex chromosomes.

Newly discovered gene could be a significant contributor to diabetes in Americans

A gene involved in the action of insulin is associated with type 2 diabetes and the body’s response to insulin, report scientists at Wake Forest University Baptist Medical Center.

Gene mutation causes Parkinson's disease in some families

An international research team, led by scientists at the National Institute on Aging (NIA), has discovered a gene, which when mutated, causes Parkinson's disease in some families.

Molecule that helps DNA replicate may make good target for cancer therapy

In order to divide, cells must first replicate their chromosomes. Cells use an array of proteins to accomplish the job, including a large enzyme complex that synthesizes new strands of DNA.

Discovery of the gene for a form of Joubert Syndrome

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered the gene for a form of Joubert Syndrome, a condition present before birth that affects an area of the brain controlling balance and coordination in about 1 in 10,000 individuals.

Researchers trim count of human genes to 20,000-25,000

Scientific description of the finished human genome sequence, reducing the estimated number of human protein-coding genes from 35,000 to only 20,000-25,000, a surprisingly low number for our species.

Scientists have devised a novel way to repair one of the genetic mutations that causes ataxia-telangiectasia

UCLA scientists have devised a novel way to repair one of the genetic mutations that causes ataxia-telangiectasia, (A-T), a life-shortening disorder that devastates the neurological and immune systems of one in 40,000 young children.

Comprehensive study raises questions about "demethylation" agents

Agents believed to selectively "restart" genes that limit cancer's growth -- a potential treatment option already in early clinical studies -- instead turn off as many genes as they turn on, a team of researchers from the National Cancer Institute and Johns Hopkins has discovered.

Technique for genetically modifying blood stem cells brings cure for blood diseases closer

The condition of mice with a genetic blood disease called beta-thalassemia improved significantly following treatment of their blood forming cells with a gene that enabled them to produce the type of hemoglobin normally found only in the fetus.

12 Oct 2004

Combination of computer science and biology could aid cancer research

The technique helps to show how cells modify their own genetic makeup and may allow cancer treatments to be tailored more precisely to a patient's disease.
