Genentech announces positive results from GA101 plus chlorambucil Phase III study on CLL

Genentech, a member of the Roche Group, today announced positive results from Stage 1 of CLL11, a Phase III randomized study to investigate the efficacy and safety profile of the investigational medicine obinutuzumab (GA101) plus chlorambucil chemotherapy compared with chlorambucil alone in people with previously untreated chronic lymphocytic leukemia (CLL).

Erbin protein critical to brain excitement

Scientists have found an early step in how the brain's inhibitory cells get excited. A natural balance of excitement and inhibition keeps the brain from firing electrical impulses randomly and excessively, resulting in problems such as schizophrenia and seizures. However excitement is required to put on the brakes.

Tributyltin exposure may cause ‘transgenerational obesity’

Research shows that offspring of mice exposed to low doses of the chemical tributyltin, used in paints, plastics, and other consumer products, have greater than normal body fat, liver fat, and fat-specific gene expression.

Clarient adopts QIAGEN’s therascreen KRAS test to diagnose colorectal cancer

QIAGEN N.V. today announced that Clarient - a GE Healthcare Company and leading provider of cancer laboratory testing services in the United States - has adopted the use of the therascreen KRAS RGQ PCR Kit (therascreen KRAS test) as a companion diagnostic to guide the use of Erbitux (cetuximab) as a treatment in patients with metastatic colorectal cancer.

Apolipoprotein E-4 useful in promoting neuron growth in the lab

A protein associated with neuron damage in people with Alzheimer's disease is surprisingly useful in promoting neuron growth in the lab, according to a new study by engineering researchers at Brown University.

Researchers create CoQ9-deficient mutant mouse model with mitochondrial encephalomyopathy

At three to six months of life, this genetic alteration in mice -similar to that occurred in human- causes a rapid degeneration in the lower limbs to death for cardiac arrest.

Hydrogen sulfide may play a wide-ranging role in staving off aging

Hydrogen sulfide (H2S) may play a wide-ranging role in staving off aging, according to a paper published online ahead of print in the journal Molecular and Cellular Biology.

Insight into reasons why precocious puberty occurs in females

New research from Oregon Health & Science University has provided significant insight into the reasons why early-onset puberty occurs in females.

ADRB receptors play a direct role in Src activation by PKA-mediated mechanism

Scientists at The University of Texas MD Anderson Cancer Center have discovered the signaling pathway whereby a master regulator of cancer cell proteins - known as Src - leads to ovarian cancer progression when exposed to stress hormones. The researchers report in the current issue of Nature Communications that beta blocker drugs mitigate this effect and reduce cancer deaths by an average of 17 percent.

FBH1 gene helps turn up the effect of chemotherapy

Chemotherapy is one of the most common treatments for cancer patients. However, many patients suffer from serious side-effects and a large proportion does not respond to the treatment. Researchers from the Biotech Research and Innovation Centre (BRIC) and Center for Healthy Aging, University of Copenhagen, now show that the gene FBH1 helps turn up the effect of chemotherapy.

Phenformin decreases size of lung tumors and increases survival in mice

Ever since discovering a decade ago that a gene altered in lung cancer regulated an enzyme used in therapies against diabetes, Reuben Shaw has wondered if drugs originally designed to treat metabolic diseases could also work against cancer.

Non-coding RNA essential for normal embryonic cardiogenesis

Many different tissues and organs form from pluripotent stem cells during embryonic development. To date it had been known that these processes are controlled by transcription factors for specific tissues. Scientists from the Max Planck Institute for Molecular Genetics in Berlin, in collaboration with colleagues at MIT and the Broad Institute in Boston, have now been able to demonstrate that RNA molecules, which do not act as templates for protein synthesis, participate in these processes as well.

One-step, off-the-shelf tool can help evaluate genetic cause of mitochondrial diseases

More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source of DNA—within the genes inside mitochondria, cellular power plants that, when abnormal, contribute to complex, multisystem diseases.

U-M researchers develop new method thet could enhance gene sequencing data

When researchers sequence the RNA of cancer cells, they can compare it to normal cells and see where there is more RNA. That can help lead them to the gene or protein that might be triggering the cancer.

Study examines how fear responses are learned, controlled and memorized

A rustle of undergrowth in the outback: it's a sound that might make an animal or person stop sharply and be still, in the anticipation of a predator. That "freezing" is part of the fear response, a reaction to a stimulus in the environment and part of the brain's determination of whether to be afraid of it.

Scientists identify genetic process in which normal liver cells transform into cancerous ones

A team of scientists from the Cancer Science Institute of Singapore (CSI) at the National University of Singapore (NUS) has identified a genetic process in which normal liver cells transform into cancerous ones. The finding provides new understanding into the pathogenesis of human cancers.

Oncolytics Biotech reports new findings at ASCO’s 2013 Gastrointestinal Cancers Symposium

What did Pope John Paul II, Ronald Reagan and Robin Gibb of the Bee Gees have in common? Each was diagnosed with colorectal cancer, the third most commonly diagnosed cancer in the world and the fourth most common cause of cancer death.

Scientists discover four processes by which gastric cancer is formed

Scientists at A*STAR's Genome Institute of Singapore (GIS) headed a study that discovered four processes by which gastric cancer is formed. This is extremely important since gastric cancer is the second most common cause of cancer deaths worldwide, claiming almost 750,000 lives annually, 60% of which are Asians.

Mutated Nesprin4 protein prevents hearing

Because half of all instances of hearing loss are linked to genetic mutations, advanced gene research is an invaluable tool for uncovering causes of deafness - and one of the biggest hopes for the development of new therapies. Now Prof. Karen Avraham of the Sackler Faculty of Medicine at Tel Aviv University has discovered a significant mutation in a LINC family protein - part of the cells of the inner ear - that could lead to new treatments for hearing disorders.
