Personal environment influences effects of genes and risk of disease

Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a study by scientists at Washington University School of Medicine in St. Louis suggests that, for most common diseases, genes alone only tell part of the story.

Gene mutation can lead to different mental illnesses when influenced by same environmental factor

Male mice born with a genetic mutation that's believed to make humans more susceptible to schizophrenia develop behaviors that mimic other major psychiatric illnesses when their mothers are exposed to an assault to the immune system while pregnant, according to new Johns Hopkins research.

Alteration in gene causes male embryos to develop as females

Scientists have discovered that the alteration of a single gene could cause some male embryos to develop as females.

Mothers exposure to farm animals and cats during pregnancy lowers risk of atopic dermatitis in children

Children whose mothers are exposed to farm animals and cats are better protected against atopic dermatitis and are less likely to develop this painful inflammation of the skin in their first two years of life. A group of researchers from the University of Zurich and other universities have published evidence supporting this theory in the Journal of Allergy & Clinical Immunology.

Scripps scientists find way to transform mature human cells into stem cells

Scripps Research Institute scientists have made a significant leap forward in the drive to find a way to safely reprogram mature human cells and turn them into stem cells, which can then change into other cell types, such as nerve, heart, and liver cells. The ability to transform fully mature adult cells such as skin cells into stem cells has potentially profound implications for treating many diseases.

Scientists propose new effort to identify proteins in cancer cells

Scientists are proposing an international effort, on the scale of the Human Genome Project (HGP), to identify all the proteins present in cancer cells. HGP was the international scientific research project that identified and mapped all the genes in humans.

Sirnaomics cemented partnership with Chinese pharmaceutical to develop siRNA therapeutics

Sirnaomics, Inc. announced today that the company has cemented a partnership with a Chinese pharmaceutical company for development of its small interfering RNA (siRNA) therapeutic (STP705) for scarless wound healing.

New clue in leukemia mystery

There is new hope for people with acute myelogenous leukemia (AML), a fast-growing cancer of the blood and bone marrow. Research led by Weill Cornell Medical College and published today in the online edition of the journal Cancer Cell reveals a surprising and unexpected cancer-causing mechanism. The investigators discovered that newly identified mutant enzymes in AML create a chemical poison to cause leukemia. Their findings should prove useful in treating patients by providing a molecular target against which to develop new drugs against one subset of AML as well as other cancers.

MicroRNA linked to mosquito blood digestion and egg development identified

Each year, dengue fever infects as many as 100 million people while yellow fever is responsible for about 30,000 deaths worldwide. Both diseases are spread by infected female Aedes aegypti mosquitoes, which require vertebrate blood to produce eggs. The blood feeding and the egg development are tightly linked to how the mosquito transmits the disease-causing virus.

Mount Sinai’s instructor receives Liz Tilberis Grant from OCRF

AnaLisa DiFeo, PhD, Instructor in the Department of Genetics and Genomic Sciences at Mount Sinai School of Medicine, has been honored by the Ovarian Cancer Research Fund (OCRF) with the Liz Tilberis Grant.

Longer life spans closer to reality

If you think life's too short, then you're not alone. A team of scientists from Texas set out to find what it would take to live a very long life and they made important discoveries that bring longer life spans much closer to reality. A new research report featured on the cover of The FASEB Journal, describes how scientists "activated" life extension in the worm, C. elegans, and in the process discovered a new metabolic state correlating with long life.

Lipids react and change to bacterial stimulus, trigger cell's immune response

For the first time, scientists have described not only the identities and quantities of fat species in a living mammalian cell in this case, a mouse macrophage or white blood cell but they also report how these lipids react and change over time to a bacterial stimulus triggering the cell's immune response.

Inserting plant's clock gene could replace circardian clock defect in humans

A gene that controls part of the 'tick tock' in a plant's circadian clock has been identified by UC Davis researchers. And not only is the plant gene very similar to one in humans, but the human gene can work in plant cells and vice versa.

LMO1 gene variation can increase neuroblastoma risk

Pediatric cancer researchers have identified variations in a gene as important contributors to neuroblastoma, the most common solid cancer of early childhood. The study team, led by researchers at The Children's Hospital of Philadelphia, found that common variants in the LMO1 gene increase the risk of developing an aggressive form of neuroblastoma, and also mark the gene for continuing to drive the cancer's progression once it forms.

Study identifies new genes responsible for early menarche

University of Minnesota School of Public Health researcher Ellen Demerath, Ph.D., is among an international group of researchers that has identified 30 new genes responsible for determining the age of sexual maturation in women. Many of these genes are also known to influence body fatness, obesity, and energy metabolism. Prior to the multi-institutional study, only four genes had been identified as contributing to the process.

Study finds duplicated region of DNA in major depressive disorder

A large genetic study of people with major depression has found that a duplicated region of DNA on chromosome 5 predisposes people to the disorder. The gene involved plays an important role in the development of nerve cells, adding to evidence that disruptions in neurotransmission networks form a biological basis for depression.

Genes linked to one-night stands and acts of infidelity

So, he or she has cheated on you for the umpteenth time and their only excuse is: "I just can't help it." According to researchers at Binghamton University, they may be right. The propensity for infidelity could very well be in their DNA.

New findings on folic acid supplementation reveal causes of low birth weight

Groundbreaking work by a team of UK scientists has identified, for the first time, a link between changes in the DNA of newborn babies, folic acid supplementation during pregnancy, and birth weight.

Diabetes plays a vital role in regulating brain cholesterol: Research

The brain contains more cholesterol than any other organ in the body, has to produce its own cholesterol and won't function normally if it doesn't churn out enough. Defects in cholesterol metabolism have been linked with Alzheimer's disease and other neurodegenerative conditions. Now researchers at Joslin Diabetes Center have discovered that diabetes can affect how much cholesterol the brain can make.

Mitochondrial brain changes contribute to risk of Alzheimer's disease: Research

What are the earliest brain changes associated with the risk of developing Alzheimer's disease. A scientific report published in the October Journal of Alzheimer's Disease finds reduced activity of an energy-generating enzyme in deceased young adult brain donors who carry a common genetic risk factor for Alzheimer's disease.
