Brain development in schizophrenia strays from normal path

Schizophrenia is generally considered to be a disorder of brain development and it shares many risk factors, both genetic and environmental, with other neurodevelopmental disorders such as autism and intellectual disability. The normal path for brain development is determined by the combined effects of a complex network of genes and a wide range of environmental factors.

Zebrafish genes linked to human respiratory diseases

Hundreds of novel genes in the zebrafish have been identified that could be functionally identical to the human genes required for forming motile cilia, hair-like structures on the surface of airway cells. These are required for removing dust and pathogens from the human airway.

Genetics reveals patients susceptible to drug-induced pancreatitis

Doctors have discovered that patients with a particular genetic variation are four times more likely to develop pancreatitis if they are prescribed a widely used group of drugs. Clinicians at the Royal Devon and Exeter NHS Foundation Trust and the University of Exeter Medical School have discovered that 17 per cent of patients who have two copies of a particular genetic marker are likely to go on to develop pancreatitis if they are prescribed thiopurine drugs.

Response Genetics Announces Novel Lung Cancer Testing Approach - Bull Thesis Strengthened

Response Genetics it has launched a new and innovative Non-Small Cell Lung Cancer Profile that merges rapid turnaround on National Comprehensive Cancer Network guideline markers with next-generation sequencing. When I covered the company in depth I had discussed that novel tests in the pipeline were being developed and could serve as a catalyst for the company.

Genetic Screening and Breast Cancer Risk

Last week, the woman who discovered BRCA1, a gene that in a mutated form increases vulnerability to breast cancer, received a Lasker Award for her achievements in medical science. Mary-Claire King of the University of Washington, who simultaneously published an article in JAMA about population-based screening for cancer-related genetic mutations , took the opportunity to call for much wider use of genetic screening for breast and ovarian cancer than currently exists.

New knowledge of genes driving bladder cancer points to targeted treatments

The story of cancer care seems so simple: find the mutated gene that causes cancer and turn it off or fix it. But rarely does a single gene cause cancer.

Schizophrenia is eight different diseases, not one

New research shows that schizophrenia is not a single disease, but a group of eight distinct disorders, each caused by changes in clusters of genes that lead to different sets of symptoms.

Muscular dystrophy: Repair the muscles, not the genetic defect

A potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease. Muscular dystrophies are a group of muscle diseases characterized by skeletal muscle wasting and weakness.

Newly Discovered Prostate Cancer Genetic Variants Could Make Testing For Risk Better

Scientists have identified 23 new genetic variants that indicate a person's risk of prostate cancer, enabling them to explain up to a third of inherited risk. Screening for prostate cancer has seen huge advances, with scientists recently identifying 23 new genetic variants associated with risk of the disease.

Ocean algae can evolve fast to tackle climate change: study

Tiny marine algae can evolve fast enough to cope with climate change in a sign that some ocean life may be more resilient than thought to rising temperatures and acidification, a study showed. Evolution is usually omitted in scientific projections of how global warming will affect the planet in coming decades because genetic changes happen too slowly to help larger creatures such as cod, tuna or whales.

Epilepsy research fund gets A 50,000 windfall

RESEARCH into the genetic causes of epilepsy has received a cash boost after a A 50,000 donation from the Buckinghamshire Freemasons. The group gave the Chalfont St Peter-based Epilepsy Society the cash windfall in order for the charity to fund work into finding a molecular cause to the condition.

Nintedanib in combination with paclitaxel achieves total remission of ...

The experimental drug nintedanib, combined with standard chemotherapy with paclitaxel, causes a total remission of tumours in 50% of patients suffering from early HER-2- negative breast cancer , the most common type of breast cancer. These are the conclusions of the Phase I Clinical Trial, sponsored by the Spanish National Cancer Research Centre and carried out by CNIO s Breast Cancer Clinical Research Unit.

Zebrafish Model of a Learning and Memory Disorder Shows Better Way to Target Treatment

Using a zebrafish model of a human genetic disease called neurofibromatosis , a team from the Perelman School of Medicine at the University of Pennsylvania has found that the learning and memory components of the disorder are distinct features that will likely need different treatment approaches. They published their results this month in Cell Reports .

Molecular genetics of mouse serotonin neurons across the lifespan.

New molecular genetics approaches have been developed over the past several years to study brain serotonin neuron development and the roles of 5-HT neurons in behavior and physiology. These approaches were enabled by manipulation of the gene encoding the Pet-1 ETS transcription factor whose expression in the brain is restricted to developing and adult 5-HT neurons.

Potential link between assisted reproduction, autism: No link found

Over the past five years, several studies have focused on infertility treatment, partly because of the coincidental rise in both the diagnosis of autism and the use of assisted reproduction. A recent study examined a potential link, and concluded that there is none.

Protein appears to protect against bone loss in arthritis

A small protein named GILZ appears to protect against the bone loss that often accompanies arthritis and its treatment, researchers report. Arthritis as well as aging prompt the body to make more fat than bone, and the researchers have previously shown GILZ can restore a more youthful, healthy mix.
