Brookhaven Lab and BioSET develop a synthetic peptide that enhances the effect of BMP-2
...ogenetic protein 2, or BMP-2. BMPs are a family of proteins
in the human body responsible for the proliferation, repair, and differentiation of cells in many tissues, including bone. The researchers designed one portion of the peptide to target the BMP-2 receptor molecules that occur on the surface of bone-...
St. Jude scientist to lead NCI Pediatric Preclinical Testing Program
...nohistochemical determination of the expression of proteins
relevant to molecularly targeted new agent testing. New agents will be tested, when feasible, near the time that they are entering evaluation in adults with cancer and before their possible initial evaluation in children. Several standard chemother...
IgG treatment during pregnancy reduces severity of rare, recurring liver condition in newborns
...purifying, identifying and cloning candidate fetal proteins
for use in blood tests. Other future directions include other clinical trials and creating animal models of NH to further study the disease and perhaps improve postnatal therapy for NH. ...
Longterm immune memory cells cells do not develop during chronic viral infections
... T cells kill the virus-infected cells and produce proteins
called cytokines that prevent the growth of viruses and make cells resistant to viral infection. During the acute phase of a viral infection, activated CD8 T cells respond aggressively for a few weeks, then about five percent of them become "memory ...

because they set off a cascade of events by activating numerous genes, which in turn lead to the pro...
A key to pregnancy-associated malaria
...egnancies. Although a family of related malaria proteins
that confer the ability to bind to the placenta had been identified previously, the role of this protein has remained elusive. Salanti et al now show that another member of this protein family, VAR2CSA, is selectively produced on the surface of infe...
Molecular clock genes influence metabolism of sugar and dietary fats
...y. They found in mice that two of the well-studied proteins
in the clock control the ability of animals to recover from the fall in blood sugar that occurs in response to insulin. The investigators demonstrate a role for the circadian clock proteins, Bmal1 and Clock, in regulating the day-to-day level...
NIH awards OHSU $4 million biodefense contract to study tuberculosis
...art of the National Institutes of Health, look for proteins
that activate the body's immune response to emerging infectious diseases. OHSU's team will focus on tuberculosis and will use cells from TB patients whose immune response has been successful at keeping the disease under control. The goal is to use t...
Researchers shed light on cancer susceptibility using 'supermice'
...of human cancers. This locus encodes two different proteins
that act together to check uncontrolled tumor development. A study to be published in the November 15 issue of Genes and Development illustrates the importance of these gene products in controlling cancer in mammals. The Tumor Suppressor group heade...
Scientists discover enzyme crucial to HIV replication
...ell nucleus where they can then be translated into proteins
to begin their most destructive work. The cellular enzyme represents a potential new target for developing improved HIV drugs, say the researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes...
Gene-silencing technique offers new way to fight drug-resistant leukemia
... Medicine. "Lyn kinase is a member of a family of proteins
that we know plays a role in cell survival, growth, and development," explains Gewirtz. "CML cells, especially those that arise in Gleevec-resistant patients, are very dependent on its function." To disable it, the researchers used short interfering ...
New finding could make addiction treatment more effective
...sleep. The primary generators of spindle waves are proteins
called calcium channels that are involved with cell communication. These channels may also help to set the phase of sleep. Chronic alcohol consumption has been shown to disturb the function of calcium channels in the thalamus, a brain region i...
Technology points to possible targets for epilepsy and Alzheimer's drugs
..."Being able to measure levels of a large number of proteins
simultaneously is a step forward in understanding ...little is known about the hundreds of thousands of proteins
that are manufactured by genes. Genes exert their effects through these proteins. Humans and other o...
Animal study suggests safer immunization approach to Alzheimer's
.... "The vaccine reduces the accumulation of amyloid proteins
for at least four weeks, providing a window during which other treatments could be used to prevent the formation of new plaques." Alzheimer's is an age-associated degenerative neurological disease and the leading cause of dementia in older people. An...

Researchers identify brain protein that halts progression of Alzheimer's
... on the study. "In Alzheimer's patients, the 'bad' proteins
significantly outnumber the 'good' proteins." Johnson discovered the effect of transthyretin while studying mice genetically engineered with defective genes taken from human patients with early-onset Alzheimer's disease. As expected, the defective ge...
