Mechanism of X-chromosome dosage compensation in Drosophila

In Drosophila, like in humans, male cells have a single X chromosome, while female cells have two. Researchers have long debated over how X and autosomal chromosome gene expression is equalized between the sexes (generally regarding two different models, known as the activation model and the inverse model).

Molecule called DJ-1 is likely to be involved in the generation of human tumors

Scientists have discovered that a molecule called DJ-1 is likely to be involved in the generation of human tumors through negative regulation of the well-known tumor suppressor, PTEN. The research, published in the March issue of Cancer Cell, has important implications for determining the prognosis of some human cancers, and may prove to be a suitable target for cancer therapy.

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.

A single change in a person’s DNA can contribute to a range of life-shortening risk factors

A woman with hypertension, low magnesium levels, and a cooperative family allowed scientists to pinpoint the mutation, which affects the genes of the mitochondria — the energy-producing power plants of the cell that are passed from mother to offspring.

Gene responsible for a rare form of dystonia known as rapid-onset dystonia parkinsonism identified

Investigators funded in part by the National Institute of Neurological Disorders and Stroke (NINDS) have identified the gene responsible for a rare form of dystonia known as rapid-onset dystonia parkinsonism (RDP).

Mustard greens, cabbages, broccoli, cauliflower and brussels sprouts help to preserve cognitive abilities in ageing women

Harvard Medical School researchers have found that women who eat lots of mustard greens, cabbages, broccoli, cauliflower or brussels sprouts in middle age preserved more of their cognitive abilities as they entered their 70s.

New research could reduce risk of strokes in younger people

The study published in this month's edition of the international journal Stroke is the first to provide evidence that blood vessels elsewhere in the body, apart from the brain, in CADASIL sufferers are abnormal in over-constricting in response to the hormone Angiotensin II.

Alzheimer Society of Canada new Alzheimer fact sheet

Dementia is a syndrome consisting of a number of symptoms that include loss of memory, judgment and reasoning, and changes in mood, behaviour and communication abilities. Alzheimer Disease, the most common form of dementia, accounts for 64 per cent of all dementias in Canada.

Extensive gene traffic, the process of genes leaving and arriving on the chromosome

Researchers at the University of Chicago have discovered there is extensive gene “traffic”—the process of genes leaving and arriving on the chromosome—on the mammalian X chromosome. They also have overturned a conventional theory about how genes evolved on the sex chromosome.

Researchers find link that could aid in treatment of kidney cyst diseases

Researchers at UT Southwestern Medical Center at Dallas have uncovered a link between two cyst-forming diseases that affect the kidneys, a finding that could lead to treatments for both a rare form of diabetes and a common kidney disease.
