Ubiquitination protects against improper Notch signaling

The Notch pathway is an important molecular signaling mechanism whose existence has been known, or at least hinted at, for nearly a century since the identification of a mutant strain of Drosophila fruit flies with "notched" wings in Thomas Hunt Morgan's lab in 1910.

Key molecular signal allows malarial parasites to target human red blood cells

Northwestern University researchers have identified a key molecular "signal" that allows malarial parasites to release virulence proteins inside human red blood cells.

Trimming fat overcomes one of the major obstacles to drug design

Biochemists at Ohio State University and their colleagues have overcome one of the major obstacles to drug design, by trimming some of the fat from a molecular sponge that scientists use to study proteins.

New advances in sickle cell disease

Excruciating pain episodes, recurrent pneumonias, strokes, severe infections, chronic hemolytic anemia, and secondary pulmonary hypertension are common complications of sickle cell disease, a life-threatening inherited defect in blood that causes normally disc-shaped red blood cells to take on a sickle shape.

Method for healing spinal injuries in dogs offers hope for preventing human paralysis

Lab tests have shown that an injection of a liquid polymer known as polyethylene glycol (PEG), if administered within 72 hours of serious spinal injury, can prevent most dogs from suffering permanent spinal damage.

Scientists have given blind nerve cells the ability to detect light

Scientists at the University of California, Berkeley, have given "blind" nerve cells the ability to detect light, paving the way for an innovative therapy that could restore sight to those who have lost it through disease.

Discovery of a new cancer gene, which, when damaged, may promote prostate cancer

Together with an international research team, researchers from VTT Technical Research Centre of Finland have developed an effective method for the screening and identification of genes that under normal conditions suppress cancer growth.

Analysis shows Remicade reduces pain associated with Crohn's disease

According to a new sub-analysis from the ACCENT I (A Crohn's disease Clinical trial Evaluating infliximab in a New long-term Treatment regimen) trial patients who received a three-dose induction regimen of Remicade experienced a significantly greater reduction in pain as assessed by four different pain questions after ten weeks, compared with patients who received a single dose of Remicade.

Gene regulated by need to process proteins linked to enlargement of protein processing factory

Part of a cellular mechanism that regulates the folding of new proteins into their proper shapes also includes a genetic response that enlarges the factory where both protein folding and packaging of proteins occurs.

An errant enzyme linked to bipolar disorder impairs awareness, perception and reasoning

The disturbed thinking, impaired judgment, impulsivity, and distractibility seen in mania, a destructive phase of bipolar disorder, may be traceable to overactivity of protein kinase C (PKC), suggests the study, funded by the National Institute of Mental Health (NIMH) and National Institute on Aging (NIA), and the Stanley Foundation.

Trojan horse technique offers potential new therapeutic approach to Alzheimer's disease

A potential new therapeutic approach to Alzheimer's disease protects brain cells in culture by drastically reducing the neurotoxic amyloid protein aggregates that are critical to the development of the disease.

Research opens new possibilities for the treatment of metabolic disorders such as diabetes and obesity

For the first time, researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected with the Catholic University of Leuven have shown clearly that receptors in yeast cells detect and react to nutrients in the cell.

Bacterium Haemophilus influenza has to secrete a glue-like protein

To stick to cells in the respiratory tract and start an infection, the bacterium Haemophilus influenza has to secrete a glue-like protein. Researchers at Washington University School of Medicine in St. Louis report this week that a study of the valve that lets out the glue has produced some surprising information.

Stress response proteins offer a promising target for a novel drug guidance system

Their study, published in the September issue of the journal Cancer Cell, demonstrates how researchers can find protein tags that are unique to cancer cells and then tweak a drug delivery system to zero in on those tags and destroy the cells.
