Blood pressure enzyme can have tumor-sensing role

By increasing production of a blood pressure-regulating enzyme in mice, researchers have found they can enhance the mouse immune system's ability to sense tumor growth.

New mouse model grants insight into the genetic and molecular mechanisms underpinning acute myeloid leukemia

Leukaemia - cancer of blood or bone marrow is caused by mutations that allow defective blood cells to accumulate and displace healthy blood.

Rare genetic variants have big impact on blood pressure

Yale University researchers report in the journal Nature Genetics that they have discovered that rare genetic variants can be associated with a dramatically lower risk of developing high blood pressure in the general population.

Scientists visualize the machinery of mRNA splicing

Recent research at Yale provided a glimpse of the ancient mechanism that helped diversify our genomes; it illuminated a relationship between gene processing in humans and the most primitive organisms by creating the first crystal structure of a crucial self-splicing region of RNA.

Rare mutations in salt handling genes protect against hypertension

Howard Hughes Medical Institute (HHMI) researchers have found that rare mutations in three genes contribute to blood pressure variation in the general population.

Cancer treatment from a common avian virus under study

Researchers on the Blacksburg and College Park, Maryland campuses of the Virginia-Maryland Regional College of Veterinary Medicine have been awarded a major new grant from the National Institutes of Health (NIH) to support innovative work that seeks to develop a treatment for cancer from a common avian virus.

New potential approach to treat spinal muscular atrophy

In the neuromuscular disease called spinal muscular atrophy, or SMA, a protein deficiency caused by a single gene mutation leads to serious damage in growing nerve cells and the muscles they control.

Campaign focuses on hereditary spastic paraplegia

A campaign to raise awareness of Hereditary Spastic Paraplegia (HSP) and announce a world first test for the little known genetic neurological disorder will be launched today by researchers at Sydney University's ANZAC Research Institute.

Discovery of more genes involved in height

Scientists are beginning to develop a clearer picture of what makes some people stand head and shoulders above the rest.

Newly identified height genes may lead to treatments for arthritis and cancer

New research which has identified 20 sections of genetic code linked to height may also lead to new treatments for arthritis and cancer.

Discovery of new genetic links to psoriasis

In the first comprehensive study of the genetic basis of psoriasis, researchers at Washington University School of Medicine in St. Louis have discovered seven new sites of common DNA variation that increase the risk of the troublesome skin condition.

Rare genetic syndrome may hold key to cure for heat stroke

A genetic disorder that can cause a fatal rise in body temperature in some patients undergoing general anesthesia may hold the key to a cure for heat stroke, according to research published in the April 4 edition of the journal Cell.

Marketing of unproven genetic tests a threat to public health

No mechanism currently exists to ensure that genetic tests are supported by adequate evidence before they go to market, or that marketing claims are truthful and not misleading, according to a policy analysis to be published April 4 in Science.

Human breast tumors' 'microenvironment' primes them for metastasis

The environment within primary breast tumors can "empower" cells that break free and enter the bloodstream to successfully invade other organs, researchers report in the April 4th Cell, a publication of Cell Press.

Genetics, environment differently influence the 'pathway of risk' leading to alcohol dependence

Alcohol dependence (AD) is influenced by both genetic and environmental factors, and its development involves "transitioning" through multiple stages of drinking behaviors.

Aripiprazole has potential for treating alcohol dependence

Aripiprazole is currently approved to treat bipolar disorder as well as schizophrenia. A new study has found that it significantly and dose-dependently increases the sedative effects of alcohol and, to a lesser degree, decreases the euphoric effects of alcohol. Future research will need to examine the beneficial versus the side effects of aripiprazole for treatment of alcohol dependence.

Answer to troublesome question of why some genetic assoc. studies have failed replication attempts

A team of researchers from Harvard School of Public Health (HSPH), Brigham and Women's Hospital (BWH), and elsewhere have described a possible reason why some studies have been unable to replicate associations between genes and traits -- namely that the strength of a gene/trait association might vary with age and that current study designs typically fail to take that into account.

Optimal level of anxiety

Anxiety gets a lot of bad press. Dwelling on the negative can lead to chronic stress and anxiety disorders and phobias, but evolutionarily speaking, anxiety holds some functional value.

Discovery of gene variant linked to nicotine addiction and lung cancer

Scientists have identified a genetic variant that not only makes smokers more susceptible to nicotine addiction but also increases their risk of developing two smoking-related diseases, lung cancer and peripheral arterial disease.

Genetic variations raise lung cancer risk for smokers and ex-smokers

Two common inherited genetic variations are associated with increased risk of lung cancer for smokers and former smokers, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports April 2 in the online edition of Nature Genetics.
