Discovery of novel function of hormone found in gut that may lower glucose levels in diabetes

A research team led by Dr. Tony Lam at the Toronto General Research Institute and the University of Toronto discovered a novel function of a hormone found in the gut that might potentially lower glucose levels in diabetes.

Research looks at cellular stress response to low oxygen

Gary Chiang, Ph.D., and colleagues at Burnham Institute for Medical Research (Burnham) have elucidated how the stability of the REDD1 protein is regulated. The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation.

Baxter completes production of batches of CELVAPAN A/H1N1 pandemic vaccine

Baxter International Inc. (NYSE: BAX) today announced that it completed production of its first commercial batches of CELVAPAN A/H1N1 pandemic vaccine in late July and is discussing plans for distribution with national health authorities, subject to obtaining appropriate authorizations. CELVAPAN, the brand name for the company’s A/H1N1 pandemic influenza vaccine, is made using Baxter’s proprietary Vero cell culture technology.

New software for cochlear implants and hearing aids

Hearing aids and cochlear implants act as tiny amplifiers so the deaf and hard-of-hearing can make sense of voices and music. Unfortunately, these devices also amplify background sound, so they're less effective in a noisy environment like a busy workplace or cafe.

Aptamers offer unique therapeutic advantages

A novel class of drugs composed of single strands of DNA or RNA, called aptamers, can bind protein targets with a high strength and specificity and are currently in clinical development as treatments for a broad range of common diseases, as described in a comprehensive review article published online ahead of print in Oligonucleotides.

Protein DNA repair complex key to avoiding DNA repair mistakes

As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows.

New understanding on Gleevec's limitations

University of Michigan researchers have developed an animal model that provides strong evidence why imatinib, marketed as Gleevec, helps patients with chronic myeloid leukemia survive longer, but does not keep the disease from returning if treatment ends.

New insight into human ciliopathy

In the September 1st issue of G&D, Dr. Karen Oegema (UCSD) and colleagues identify the molecular basis of the lethal developmental disorder, hydrolethalus syndrome, and reveal that hydrolethalus syndrome actually belongs to the emerging class of human ciliopathy diseases.

Clinical trial to test gene therapy for Alzheimer’s disease

Researchers at the Shiley-Marcos Alzheimer's Disease Research Center at the University of California San Diego are about to launch a Phase 2 clinical trial to test a gene therapy treatment for Alzheimer’s disease (AD) called CERE-110.

Discovery of potential candidate protein for cancer vaccines

Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. The finding suggests that a vaccine against the protein might prevent malignancies in high-risk individuals.

Jefferson names endowed Professorship in transplant surgery

Cataldo Doria, M.D., Ph.D., F.A.C.S., director, Division of Transplant Surgery, in the Department of Surgery at Thomas Jefferson University Hospital, has been named the Nicoletti Family Professor of Transplant Surgery. This endowed professorship is a generous gift of Robert and Beatrice Nicoletti and their family. The family cited the care they received at Jefferson when Robert received a new kidney donated by his own daughter, as the reason for their donation.

Viral RNA linked to human immune response

In its fight against an intruding virus, an enzyme in our immune system may sense certain types of viral RNA pairs, according to scientists.

Silenced genes provide warning sign of blood cancer

In many types of cancer, parts of the genetic material of tumor cells are switched off by chemical labels called methyl groups. This kind of methyl labeling ranges among the epigenetic changes that do not change the sequence of DNA building blocks. Such labels are found particularly often in genes which act as important inhibitors of pathogenic cell growth.

New method selectively kills metastatic melanoma

An international team of researchers has identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma – a cancer that is highly resistant to current treatment strategies.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia.

Stem cell technology innovation could reduce the number of animal experiments

Researchers from the University of Bath are embarking on a project to use stem cell technology that could reduce the number of animal experiments used to study conditions such as motor neurone disease.

New function for missing protein in Duchenne muscular dystrophy found

Researchers at the University of Minnesota and National Institutes of Health have identified a new function for the protein missing in people with the most common and ultimately lethal form of childhood muscular dystrophy.

New research helps explain why treated genital herpes sores boost risk of HIV infection

New research helps explain why infection with herpes simplex virus-2 (HSV-2), which causes genital herpes, increases the risk for HIV infection even after successful treatment heals the genital skin sores and breaks that often result from HSV-2.

Discovery of mechanism that protects somatic cells against the behaviour of germ cells

An IRB Barcelona research team discovers the mechanism that favors the correct separation of germ cells -- future ovules and sperm -- from the rest of the cells during embryonic development

Discovery of unique 'DNA signature' in human sperm - unlocks egg's fertility

Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes a DNA signature that can only be recognised by an egg from the same species. This enables fertilisation and may even explain how a species develops its own unique genetic identity.
