Nerve growth factor positively related with liver cancer - potential therapy target

Nerve growth factor (NGF), as the name says, is an essential peptide factor for the growth and differentiation of neuronal cells.

Secrets of protein folding revealed

A team led by biophysicist Jeremy Smith of the University of Tennessee and Oak Ridge National Laboratory (ORNL) has taken a significant step toward unraveling the mystery of how proteins fold into unique, three-dimensional shapes.

LL37 peptide provides a new potential target for autoimmune disease

A human peptide that acts as a natural antibiotic against invading microbes can also bind to the body's own DNA and trigger an immune response in the absence of an infection, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in an early online publication in Nature.

Nanotechnology helps identify molecular signature common to Lou Gehrig's disease

A nanotechnology developed by a University at Buffalo professor has enabled researchers to identify a molecular signature common to both familial and sporadic cases of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease.

Low level of neuronal receptor LR11 linked to Alzheimer's disease

Results of a new study indicate a strong link between the loss of the neuronal receptor LR11and onset of mild cognitive impairment (MCI), often a harbinger of Alzheimer's disease.

New blood pressure drug Tekturna benefits heart failure patients too

A new blood pressure drug called Tekturna made by Novartis has been found to benefit heart failure patients also.

A drug-sensitive 'traffic cop' tells potassium channels to get lost

Our brains are buzzing with electrical activity created by sodium and potassium ions moving in and out of neurons through specialized pores. To prevent the constant chatter from descending into chaos the activity of these ion channels has to be tightly regulated.

The first clinically available oral direct renin inhibitor shows promise in heart failure

Drugs that block a hormonal cascade, known as the renin-angiotensin-aldosterone system (RAAS), help patients with heart failure. Direct renin inhibitors (DRIs) block the RAAS at its first and rate-limiting step.

Discovery of novel cause of iron overload in patients with thalassemia

According to the study, thalassemia patients overproduce a protein called GDF15, which suppresses the production of a liver protein, hepcidin, which in turn leads to an increase in the uptake of dietary iron in the gut.

Researchers unlock mystery of a third olfactory system

Researchers at the University of Maryland School of Medicine have found a "nose within the nose," a unique olfactory system within the noses of mice that is able to "smell" hormones involved in regulating water and salt balance in the body.

Early heart treatment can reverse damage

University of Minnesota researchers have discovered that treating people who have early cardiovascular abnormalities, but show no symptoms of cardiovascular disease, can slow progression and even reverse damage to the heart and blood vessels.

All eukaryotic kinases share 1 common set of substrates

Kinase mediated phosphorylation is generally recognised as the major regulator of virtually all metabolic activities in eukaryotic cells including proliferation, gene expression, motility, vesicular transport and programmed cell death.

Targeted quantum dot conjugates for siRNA delivery

Take a quantum dot, add a coating of poly(ethylene glycol) (PEG), and attach a homing peptide and a piece of small interfering RNA (siRNA), and the result is a targeted nanoparticle that can stop the production of a specific protein by a targeted cell.
