Researchers discover NPC1 protein as crucial for Ebola virus to enter host cells

Although outbreaks are rare, Ebola virus, the cause of Ebola hemorrhagic fever (EHF), is one of the deadliest known viruses affecting humans. According to the World Health Organization (WHO), approximately 1,850 EHF cases with more than 1,200 deaths have been documented since the virus was identified in 1976.

Largest ever molecular-genetic study of ependymomas of the cerebellum

Ependymomas are the second most frequent type of malignant brain tumor in children. Ependymoma develops from precursor cells of the tissue that lines the hollow cavities of the brain. Therapy results of ependymoma vary immensely: While in some patients tumor growth comes to a standstill after surgery and radiotherapy, in other children the disease rapidly takes a severe course.

Scientists identify molecular pathway that plays a key role in stress-related DNA damage

Working closely with a team of researchers from Duke University, scientists from the Florida campus of The Scripps Research Institute have helped identify a molecular pathway that plays a key role in stress-related damage to the genome, the entirety of an organism's hereditary information.

EMA accepts Pfizer's regulatory submissions of two investigational cancer drugs for review

Pfizer Inc. announced today that the European Medicines Agency (EMA) has accepted Pfizer's regulatory submissions for review of two investigational compounds - crizotinib, an oral first-in-class anaplastic lymphoma kinase (ALK) inhibitor, for the treatment of patients with previously treated ALK-positive advanced non-small cell lung cancer (NSCLC); and bosutinib for the treatment of adult patients with newly diagnosed Philadelphia chromosome positive (Ph+) chronic myeloid leukemia (CML) in the chronic phase.

Insight into how molecular motor proteins save energy

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets moved around the cell, and when.

G-CSF therapy does not induce chromosomal instability in healthy stem cell donors

According to a study published in Blood, the Journal of the American Society of Hematology (ASH), researchers have reported that administration of granulocyte colony-stimulating factor (G-CSF), a drug that releases stem cells from the bone marrow into the blood, is unlikely to put healthy stem cell donors at risk for later development of abnormalities involving loss or gains of chromosomes that have been linked to hematologic disorders such as myelodysplastic syndromes (MDS) and acute myeloid leukemia.

Blood test early in pregnancy to detect baby’s gender

While carrying the child, a mother's blood has cell-free fetal DNA floating around in it, and it's possible to use this to test for the baby's sex. In a meta-analysis that covered more, the test was found to be 95% efficient in guessing the sex of the fetus — and it works from as early as seven weeks. As the fetus and the placenta develop, the amount of DNA present in the mother increases, boosting the accuracy of the test, which hits its peak at 20 weeks.

Noninvasive prenatal DNA test can detect fetus at risk for sex-linked disorders

As a noninvasive method of determining the sex of a fetus, tests using cell-free fetal DNA obtained from the mother's blood after 7 weeks gestation performed well, while urine-based tests appear to be unreliable, according to a review and analysis of previous studies, reported in the August 10 issue of JAMA.

Researchers discover gene variant linked to meningiomas

The causes of brain tumours have been hard to discern in most cases. But Umeå researchers have previously identified an inherited predisposition for brain tumours, and now, in an international collaboration, they have also discovered a genetic variation that increases the risk of a certain type of brain tumour, called meningiomas.

Scientist urges federal officials to decide on genetically engineered salmon for consumption

A Purdue University scientist is urging federal officials to decide whether genetically engineered salmon would be allowed for U.S. consumption and arguing that not doing so may set back scientific efforts to increase food production.

Higher levels of B cells make women more prone to autoimmune diseases

Researchers at National Jewish Health have discovered a type of cell that may contribute to autoimmune disease and suggests why diseases such as lupus, multiple sclerosis and rheumatoid arthritis strike women more frequently than men. The cells, a subset of immune-system B cells, make autoantibodies, which bind to and attack the body's own tissue.

Incyte announces FDA acceptance of NDA filing for ruxolitinib to treat myelofibrosis

Incyte Corporation announced today that the US Food and Drug Administration (FDA) has accepted for filing the New Drug Application (NDA) for Incyte's lead investigational compound, ruxolitinib, as a potential treatment for patients with myelofibrosis.

British scientists find seven new gene variants linked to prostate cancer

Cancer Research UK-funded scientists have taken a further step to identifying men at a greater risk of prostate cancer with the discovery of seven new variants in the human genome that increase the chances of developing the disease. The research is published in Nature Genetics.

Human genes can be patented in U.S. - Court overrules previous ruling

A lower court in the U.S. had earlier ruled that human genes cannot be patented by biotech companies who use them for diagnostic purposes. Now a federal appeals court ruled on Friday that genes can be patented. The Court of Appeals for the Federal Circuit, which specializes in patent cases, said that Myriad Genetics was entitled to patents on two human genes used to predict if women have an increased risk of getting breast and ovarian cancer.

Researchers identify gene linked to Lesch-Nyhan disease

In humans, inherited mutations in a gene called HPRT1 lead to very specific self-destructive behavior. Boys with Lesch-Nyhan disease experience uncontrollable urges to bite their fingers, slam their arms into doorways and otherwise harm themselves.

Insect virus holds key to safer stem cell therapy: Singapore scientists

The future of regenerative medicine lies in harnessing the potential of the human body to renew and repair itself. Now, scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a new genetic engineering technique that promises safer stem cell therapy for cancer patients. Using an insect virus, the team of researchers successfully inserted a therapeutic gene into a safe site in the DNA of human embryonic stem cells without compromising the functionality of the engineered cells.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Scientists identify possible genetic variations linked to eating disorders

A substantial number of people with eating disorders, such as anorexia nervosa have a chronic course. They are severely underweight and have a high likelihood of dying from malnutrition. No treatment has been found that helps people who are chronically ill. Now, a new study sheds light on the reason that some people have poor outcome.
