Research reveals a novel key player in the initiation of colon cancer

Gastric and colorectal cancers account for more than 1 million deaths worldwide every year and several research groups have been working to identify the molecular events that result in the initiation and progression of these tumors.

Women who feel more loved are less at risk for major depression than men

Virginia Commonwealth University researchers have found that women who feel more loved and supported by their friends, relatives and children are less at risk for major depression than men, suggesting important gender differences in the pathways leading to depression.

Mitochondria - the energy factories in our cells - can sustain a cancer

University of Glasgow scientists have discovered how mitochondria - the energy factories in our cells - can sustain a cancer, reporting their findings in a new study published in Cancer Cell.

Gene dynamin 2 underlies one form of Charcot-Marie-Tooth disease

A gene that plays many fundamental roles in cells throughout the body has, for the first time, been implicated in human disease, according to researchers at the Duke Center for Human Genetics.

What causes puberty to begin?

Puberty, that awkward phase when boys and girls are primed for their sexual reproductive years as men and women, appears to be triggered by the brain's own version of "It takes two to tango," whereby a signal literally gets turned on by a molecule that is produced by a gene aptly named KiSS-1.

Significant advance toward understanding lifelong process of blood cell formation

A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role of a key gene known to be required for blood cell formation. Information gained from this research will be useful for future studies aimed at directing stem cell differentiation in a variety of potential therapeutic contexts.

Do genes play a role in determining whether a man is gay or heterosexual?

In the first-ever study combing the entire human genome for genetic determinants of male sexual orientation, a University of Illinois at Chicago researcher has identified several areas that appear to influence whether a man is heterosexual or gay.

Psychiatric illness drugs may protect the brain cells that die in people with Huntington's disease

Researchers at UT Southwestern Medical Center have discovered that drugs commonly used to treat psychiatric illnesses and blood disorders in humans may protect the brain cells that die in people with Huntington's disease, possibly delaying the onset and slowing the progression of the disease.

Physical traits, genetic test help with early diagnosis of aneurysm syndrome

A research team led by Johns Hopkins doctors has defined the physical traits and genetic basis of a new aortic aneurysm syndrome that is extremely aggressive and can cause death in early childhood. Early diagnosis of the syndrome and rapid surgical repair of the swollen aorta can save lives, the researchers report in the Jan. 30 advance online section of Nature Genetics.

One of the most exciting developments in clinical research in decades

One of the most exciting developments in clinical research in decades is taking place at the University of Leeds, led by our professor of cancer medicine Peter Selby in collaboration with the Medical Research Council.

Health initiatives have led to Arab and Israeli cooperation in the Middle East

The cross-border project led to Palestinian and Israeli basic science research programmes between Bethlehem University and Tel Aviv University in the genetics of hearing loss, and generated joint-publications. From this followed a project to screen and habilitate 17 000 Israeli, Jordanian and Palestinian newborns for hearing loss.

Researchers discover way to overcome major hurdle in gene therapy for cancer

In a new study published in the Jan. 25 issue of the Proceedings of the National Academy of Sciences (PNAS), the researchers demonstrated that the technique works by incorporating it into a specially designed virus. The virus eradicated prostate cancer cells in the lab and in animals while leaving normal cells unscathed.

Instant tea may be a source of harmful levels of fluoride

The researchers found that some regular strength preparations contain as much as 6.5 parts per million (ppm) of fluoride, well over the 4 ppm maximum allowed in drinking water by the Environmental Protection Agency and 2.4 ppm permitted in bottled water and beverages by the Food and Drug Administration.

Theory on evolution of essential genes is overturned

A gene passed on by fathers that plays a vital role in helping fertilised eggs to develop into adults has helped scientists overturn the idea that essential genes have always been part of the genetic makeup of a species.

Local environment directly influences adult stem cell reservoirs

Using the common fruit fly, researchers at UT Southwestern Medical Center have discovered that an intricate set of signals released by stem cells' surroundings governs their maintenance.

Genetic defect leads to electrical instability and mechanical pump failure

In genetic mapping of a large family with several members affected by a type of heart failure called dilated cardiomyopathy (DCM), the Mayo Clinic team found a defect in a gene on chromosome 3 called SCN5A.

Research may provide the basis for development of a new, extensive immunotherapy for human tumors

Scientists have made significant progress towards understanding how the immune system can be more specifically and efficiently targeted against cancer cells. The research, published in the January issue of Immunity, may provide the basis for development of a new, extensive immunotherapy for human tumors.
