Vaccine to cope with viral diversity in HIV

The ability of HIV-1 to develop high levels of genetic diversity and acquire mutations to escape immune pressures contributes to our difficulties in producing a vaccine.

Scientists discover pathway that promotes muscle cell survival in mice

Scientists at the Salk Institute for Biological Studies have identified an enzyme that pumps up a cell's ability to maintain healthy muscle and restores normal muscle function in genetically engineered mice with weak muscles.

The convergence of embryonic and cancer signaling pathways: role in tumor cell plasticity

In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells.

Genetic risk for early death in rheumatoid arthritis

A chronic autoimmune disease, rheumatoid arthritis (RA) is marked by inflammation that takes a progressive toll on not only the joints, but also various organs and the whole body.

New test for liver disease

A researcher at the Stanford University School of Medicine has helped confirm the reliability of a new test for liver disease that is ushering in the long-promised era of personalized medicine based on each individual's genetic makeup.

Exercise pill switches on master regulator that controls the ability of cells to burn fat

By giving ordinary adult mice a drug - a synthetic designed to mimic fat - Salk Institute scientist Dr. Ronald M. Evans is now able to chemically switch on PPAR-d, the master regulator that controls the ability of cells to burn fat.

Environment rich in sensory stimuli restores memory in mice with neurodegeneration

Mice whose brains had lost a large number of neurons due to neurodegeneration regained long-term memories and the ability to learn after their surroundings were enriched with toys and other sensory stimuli, according to new studies by Howard Hughes Medical Institute researchers.

Respiratory control in insects: integration from the gene to the organism

Because of new imaging technology, researchers are getting a better understanding of a physiological paradox: how insects, which have a respiratory system built to provide quick access to a lot of oxygen, can survive for days without it.

Big win in the battle against diabetes

In newly published research scientists have revealed that they have discovered more genes linked to Type 2 Diabetes.

Important new discovery in metabolomics

St. Jude investigators have mapped out many of the dynamic genetic and biochemical changes that make up a cell's response to a shortage of a molecule called Coenzyme A (CoA), a key player in metabolism.

Ten genetic variants associated with type 2 diabetes

Ten genetic variants associated with type 2 diabetes, a disease which impacts more than 170 million people worldwide, have been identified or confirmed by a U.S.-Finnish team led by scientists at the University of Michigan School of Public Health.

New genetic risk factors for type 2 diabetes

In the most comprehensive look at genetic risk factors for type 2 diabetes to date, a U.S.-Finnish team, working in close collaboration with two other groups, has identified at least four new genetic variants associated with increased risk of diabetes and confirmed existence of another six.

New mechanism identified for resistance to targeted lung cancer drugs

An international research team, led by investigators from the Massachusetts General Hospital (MGH) Cancer Center and Dana-Farber Cancer Institute (DFCI), has found a new way that some lung tumors become resistant to treatment with targeted therapy drugs like Iressa and Tarceva.

New gene discovered in human stem cells may benefit transplant patients

Oxford scientists have revealed a link between a gene and the activity of human blood stem cells, giving hope that stem cell transplant success for blood cancer patients may be significantly improved.

New Parkinson's Disease diagnostic test

While Florey researchers have also created a genetic test for Parkinson's Disease (PD) [10% of PD cases are caused by genetic factors], this new test has a broader application by screening for many different types of PD and monitoring treatment, as well as measuring the effectiveness of drugs being developed to treat the disease.

Researchers find clear genetic risk factors for type 2 diabetes

Scientists from the Broad Institute of Harvard and MIT, Lund University and Novartis have announced the discovery of three unsuspected regions of human DNA that contain clear genetic risk factors for type 2 diabetes, and another that is associated with elevated blood triglycerides.
