Novel connection found between biological clock and cancer
Dartmouth Medical School geneticists have discovered that DNA damage resets the cellular circadian clock, suggesting links among circadian timing, the cycle of cell division, and the propensity for cancer. view more (2006-06-30)
Diet a major factor in breast cancer - time for government action
Hamburg, Germany: The rapid increase in the knowledge of breast cancer determinants and the continuing increase in incidence of breast cancer means that it is time to move from knowledge to action, a scientist said today (Friday 19 March) at the 4th European Breast Cancer Conference. Dr. Franco Berrino, head of preventive and predictive medicine... view more... (2004-03-17)
New clues to amyloidoses ?
Familial amyloid polyneuropathy (FAP), a hereditary disease characterised by abnormal deposits of insoluble protein in the organs, results from a mutation in a single gene (the transthyretin or TTR gene). Nevertheless, disease incidence and age of onset can vary significantly between patients what have always puzzled scientists. Now, in the latest... view more... (2005-02-18)
Different mutations in a single gene suggests Parkinson's disease is primarily an inherited genetic disorder
Two new international studies by researchers at the Mayo Clinic site in Florida are rounding out the notion that Parkinson's disease is largely caused by inherited genetic mutations that pass through scores of related generations over hundreds, if not thousands of years. view more (2008-04-17)
New sleep gene discovery wakes up scientists
Proteins that regulate sleep and biological timing in the body work much differently than previously thought, meaning drug makers must change their approach to making drugs for sleep disorders and depression and other timing-related illnesses. view more (2006-07-05)
Rare mutation causes early heart disease and metabolic syndrome
Yale School of Medicine researchers have identified a rare defect in a single gene that poses a substantial risk for metabolic syndrome and early heart disease, the leading cause of death worldwide. view more (2007-03-02)
Enzyme defect leads to hyperinsulinism
A recent study in the Journal of Biological Chemistry confirms that mutations in an enzyme called glutamate dehydrogenase can cause congenital hyperinsulinism. view more (2006-05-25)
Model to study age-related macular degeneration could pave way for better treatment
Researchers at the University of Pennsylvania School of Medicine have created the first animal model of age-related macular degeneration (AMD) caused by a mutation known to produce disease in people, an important first step in developing treatments. view more (2007-10-10)
Large study documents how p53 mutations link to high-grade breast cancer, poor outcomes
In what is believed to be the largest study of its kind in the US, researchers have found that almost 26 percent of women studied who have breast cancer have mutations in a gene important in controlling cell growth and death, and that patients with mutations in this gene -- known as p53 - had poorer outcomes including a significantly increased... view more...

Lineage trees for cells
Some fundamental outstanding questions in science - "Where do stem cells originate?" "How does cancer develop?" "When do cell types split off from each other in the embryo?" - might be answered if scientists had a way to map the history of the body's cells going back to the fertilized egg. view more (2005-10-31)
MIT researchers offer glimpse of rare mutant cells
MIT biological engineers have developed a new imaging system that allows them to see cells that have undergone a specific mutation. view more (2008-07-22)
Study reveals mechanism for cancer-drug resistance
Using the worm Caenorhabditis elegans, researchers at UT Southwestern Medical Center have discovered a mechanism by which cancer cells become resistant to a specific class of drugs. view more (2006-10-11)
New insights into progressive hearing loss
In parallel studies in human and mouse, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss. view more (2009-04-13)
Genetic counselors turn to unconventional counseling to meet demand for genetic testing
Imagine receiving genetic test results for a disease you could develop later in life without having anyone with whom to discuss your options for managing the risk. That's becoming a common occurrence as people turn to the Internet and other outlets for genetic testing without genetic counseling. view more (2008-03-17)
Hormones increase frequency of inherited form of migraine in women
Familial hemiplegic migraine (FHM) is an inherited form of severe migraine that is accompanied by visual disturbances known as aura. As with other types of migraine, it affects women more frequently than men. view more (2008-12-23)
Cancer immunoresistance linked to loss of tumor suppressor gene
Cancer immunoresistance may be partially due to loss of a well-known tumor suppressor gene, according to new research led by Andrew T. Parsa, MD, PhD, assistant professor of neurological surgery at the University of California, San Francisco. view more (2006-12-11)
Viral genetic differences are possible key to HIV dementia
The study of 18 HIV-positive subjects shows that HIV in the brain and central nervous system is genetically different from HIV that lives in the blood and peripheral tissues. view more (2006-07-26)
Rates of rare mutations soar 3 to 4 times higher in schizophrenia
People with schizophrenia have high rates of rare genetic deletions and duplications that likely disrupt the developing brain, according to studies funded in part by the National Institutes of Health. view more (2008-03-28)
Second gene discovered for recessive form of brittle bone disease
Researchers at the National Institutes of Health and other institutions have found a second genetic defect that accounts for previously unexplained forms of osteogenesis imperfecta (OI), a disorder that weakens bones, sometimes results in frequent fractures and is sometimes fatal. view more (2007-02-09)
Forced evolution: Can we mutate viruses to death?
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University bioengineers. view more (2008-11-11)
