Gilead reports topline results from sofosbuvir Phase 3 trial in Japan for treatment of HCV infection

Gilead Sciences, Inc. today announced topline results from a Phase 3 clinical trial (Study GS-US-334-0118) in Japan evaluating the once-daily nucleotide analog polymerase inhibitor sofosbuvir in combination with ribavirin (RBV) for the treatment of genotype 2 chronic hepatitis C virus (HCV) infection.

International scientists identify novel genetic defects that induce oesophageal cancer

A team of scientists from the Cancer Science Institute of Singapore at the National University of Singapore and National University Cancer Institute Singapore, and their collaborators from the Cedars-Sinai Medical Centre, UCLA School of Medicine, demonstrated that a number of novel genetic defects are able to induce oesophageal cancer.

New gene-editing system holds potential for treating many genetic disorders

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

Genetic variations influence risk for developing choline deficiency symptoms

What is now considered to be the "right" amount of the essential nutrient, choline, might actually be "wrong," depending on who you are. That's because scientists have found that the "right" amount of choline needed by an individual is influenced by a wide range of factors, including gender, life stage, race and ethnicity of the individual.

Study suggest that women are resistant to mutations that contribute to autism

It takes more mutations to trigger autism in women than in men, which may explain why men are four times more likely to have the disorder, according to a study published 26 February in the American Journal of Human Genetics1.

Scientists unlock one of mysteries of modern genetics

Scientists at Indiana University have unlocked one of the mysteries of modern genetics: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds that cells don't know to silence some genes based on information hardwired into their DNA sequences, but recognize heritable chemical marks that are added to the genes. These chemical tags serve as a form of molecular memory, allowing cells to recognize the genes and remember to silence them again in each new generation.

Researchers identify steps by which cell removes RNA from cytoplasm

RNA encodes the proteins that play a key role in cellular reproduction, but the manner in which cells regulate its removal once these proteins are synthesized remains a mystery. One piece of this mystery has been solved as researchers at the University of North Carolina at Chapel Hill who have identified the steps by which a cell removes RNA from the cytoplasm.

New tool pinpoints genetic sources of disease

Many diseases are the result of either variations in the genome or reversible chemical changes to DNA, known as the epigenome. New data obtained by Johns Hopkins scientists show a connection between genetic variants and epigenetic information.

Two new risk loci for bipolar disorder identified

Researchers have found two new risk loci for bipolar disorder in a genome-wide association study of 2.3 million single-nucleotide polymorphisms.

Neurexin proteins play key role in formation of synaptic connections

Neuroscientists and bioengineers at Stanford are working together to solve a mystery: how does nature construct the different types of synapses that connect neurons -- the brain cells that monitor nerve impulses, control muscles and form thoughts.

Hepatitis C patients with ITPA gene variants exhibit lower risk of relapse after treatment

More than 100 million humans around the world are infected with hepatitis C virus. The infection gives rise to chronic liver inflammation, which may result in reduced liver function, liver cirrhosis and liver cancer.

Study: Musical aptitude is affected by a combination of genes involved in auditory pathway

Multiple regions in the human genome are reported to be linked to musical aptitude, according to a study published this week in Molecular Psychiatry.

Researchers explore how genetics affects causes and prevalence of preterm birth

More than 450,000 babies are born too soon each year in the U.S. Preterm birth is a serious health problem that costs the nation more than $26 billion annually, according to the Institute of Medicine, and is the leading cause of newborn death.

Homologous recombination technology for research applications in genetically modified rodents: an interview with Alexandre Fraichard, CEO, genOway

Homologous recombination is a technology that enables the targeted insertion of nucleotide fragments into the genome of a cell. It is called ‘homologous’ because it uses a sequence that is a homologue to the sequence being targeted in a gene, so that the sequence is recognized.

New findings shed light on how gene mutation causes motor neurone disease

Researchers have discovered a mechanism that may explain how a recently discovered mutation causes two devastating neurological diseases.

UCLA develops experimental treatment that eliminates acute type of leukemia in mice

A diverse team of scientists from UCLA's Jonsson Comprehensive Cancer Center has developed an experimental treatment that eradicates an acute type of leukemia in mice without any detectable toxic side effects.

Research reveals very unique evolutionary innovations in primate brain

New research by UC Santa Barbara's Kenneth S. Kosik, Harriman Professor of Neuroscience, reveals some very unique evolutionary innovations in the primate brain.

UCLA scientists developed experimental treatment that eradicates acute type of leukemia in mice

A diverse team of scientists from UCLA's Jonsson Comprehensive Cancer Center have developed an experimental treatment that eradicates an acute type of leukemia in mice without any detectable toxic side effects. The drug works by blocking two important metabolic pathways that the leukemia cells need to grow and spread.

Blocking mechanisms for DNA repair may help to potentiate chemotherapy, says study

Chemotherapies are cancer treatments that work by inducing lesions in the DNA of tumour cells in order to inhibit their proliferation. However, the body naturally tries to repair these lesions, and thus reduces the efficacy of chemotherapy.

New DNA Quantification kits may help scientists to quickly assess highly compromised human DNA

Forensic scientists can now more quickly assess the quantity and quality of human DNA in highly compromised and degraded casework samples and provide the critical information needed to drive informed decisions on subsequent steps in the analysis process, thanks to two new Life Technologies quantification solutions announced today by Thermo Fisher Scientific.
