Researchers question genetic screening programs

The study by a team at Shaare Zedek Medical Centre in Jerusalem, is the first to examine what couples actually did when they learned their unborn child had a condition called Gaucher disease, an inherited condition which can be effectively treated.

Test for lung cancer looks for discomforting quiet among protective genes

When it is quiet – "almost too quiet" – in movies, it is a sign that something is about to go wrong for the good guys.

Re-engineered human T cells effectively target and kill cancerous B cells

Human white blood cells, engineered to recognize other malignant immune cells, could provide a novel therapy for patients with highly lethal B cell cancers such as acute lymphoblastic leukemia (ALL), according to researchers at Memorial Sloan-Kettering Cancer Center (MSKCC).

New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape.

Liver cancer marker could yield blood test for early detection

In the face of an emerging liver cancer crisis in Asia, researchers at the Chinese University of Hong Kong have developed a test that could help millions.

Rheumatoid arthritis genes

A paper published this week in the open access journal PLoS Medicine provides strong evidence that one specific part of the genome is associated with rheumatoid arthritis.

Gene profiling can single out the worst cases of multiple myeloma and guide therapy

Multiple myeloma patients vary widely in how they respond to treatment, but now researchers at the Myeloma Institute for Research and Therapy at the University of Arkansas for Medical Sciences have identified a small subset of genes whose activity could predict high-risk cases and potentially guide therapy in the future.

Chronic stress can steal years from caregivers' lifetimes

The chronic stress that spouses and children develop while caring for Alzheimer's disease patients may shorten the caregivers' lives by as much as four to eight years, a new study suggests.

Women more depressed and men more impulsive with reduced serotonin functioning

Women and men appear to respond differently to the same biochemical manipulation.

Black men do not have more aggressive prostate cancer

A University of Minnesota study of prostate cancer tumors from Caucasian and African-American men has shown no evidence that the cancer is more aggressive in black men.

New understanding of gene mutation responsible for fragile X syndrome

Scientists have discovered how the gene mutation responsible for fragile X syndrome - the most common inherited form of mental retardation - alters the way brain cells communicate.

Smoking-cessation may be in the genes

Whether a smoking-cessation drug will enable you to quit smoking may depend on your genes, according to new genotyping research from the Centre for Addiction and Mental Health (CAMH).

Mechanism for the in-vivo transport of siRNA

It all started with flowers: in the nineties of the last century Norwegian researchers discovered that additional copies of a particular gene in petunias inhibited its activity instead of reinforcing it as had been assumed.

JAK genes and cancer

Cancer-causing genes can work in more powerful and sneaky ways than have been realized.

Mutations in the glucocerebrosidase gene are risk factors for Parkinson's disease

People with a certain gene mutation are more likely to get Parkinson's disease before the age of 50 compared to those without the gene abnormality, according to a study published in the September 18, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

The importance of gene regulation for common human disease

A new study published in Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code.
