New hope for Huntington disease cure

Researchers provide ground-breaking evidence for a cure for Huntington disease in a mouse offering hope that this disease can be relieved in humans.

Scientists cracking virus protection shield

Scientists reveal the structure of a protein that packages the viral genome and helps viruses to replicate while avoiding human immune reactions

Central nervous system can sometimes send out signals that invite hostile immune system attacks

It may sound like a case of blame the victim, but researchers at Washington University School of Medicine in St. Louis have shown that cells in the central nervous system can sometimes send out signals that invite hostile immune system attacks.

New roles for growth factors

During embryonic development, nerve cells hesitantly extend tentacle-like protrusions called axons that sniff their way through a labyrinth of attractive and repulsive chemical cues that guide them to their target.

From DNA to RNA to protein

Of the thousands of proteins produced in our cells, few are as important as the enzyme RNA polymerase (RNAP), which has the unique ability to faithfully copy genetic information from DNA.

Bioinformatics used to advance human disease research

The use of computers to advance human disease research - known as bioinformatics -- has received a major boost from researchers at the La Jolla Institute for Allergy & Immunology (LIAI).

Transcription factors act not only in isolation to regulate distinct sets of genes

Scientists eager to help develop a new generation of pharmaceuticals are studying cellular proteins called transcription factors, which bind to upstream sequences of genes to turn the expression of those genes on or off.

Researchers identify new keys to regulation of bacterial gene expression

The cellular process of transcription, in which the enzyme RNA polymerase constructs chains of RNA from information contained in DNA, depends upon previously underappreciated sections of both the DNA promoter region and RNA polymerase

Researchers identify mechanism that regulates how many new cells are produced by each intestinal stem cell

Researchers at Karolinska Institutet have identified an important mechanism that regulates how many new cells are produced by each intestinal stem cell.

Discovery of gene behind iron accumulation in brain has implications for Parkinson's, Alzheimer's

Oregon Health & Science University researchers have identified the gene behind a group of rare, progressive childhood disorders caused by an abnormal buildup of iron in the brain.

First drug treatment for late-stage cervical cancer approved

FDA has approved a combination of Hycamtin (topotecan hydrochloride) and cisplatin for use as the first drug treatment for women with late-stage cancer of the cervix.

Burkitt lymphoma gene expression signature identified

An international research study involving the University of Nebraska Medical Center, the National Cancer Institute and 10 other institutions has successfully identified the gene expression signature for Burkitt lymphoma.

Dasatinib offers new options for leukemia patients

Dasatinib, an experimental drug under development by Bristol-Myers Squibb, reverses the signs and symptoms of patients whose chronic myeloid leukemia has failed to respond to Gleevec, which is considered the standard of treatment for the disorder.

Circulating bone-marrow derived cells do not contribute to egg formation

Ovulated egg cells, or oocytes, in adult female mice are not formed from germ cells in the blood or bone marrow.

Scientists watch the behavior of a single gene in real time

Scientists at the Albert Einstein College of Medicine of Yeshiva University have observed for the first time that gene expression can occur in the form of discrete "pulses" of gene activity.

Scientists reveal two paths of neurodegeneration

Wiring the developing brain is like creating a topiary garden. Shrubs don't automatically assume the shape of ornamental elephants, and neither do immature nerve cells immediately recognize the "right" target cell.

Stem cell breakthrough

Researchers at The Hospital for Sick Children (SickKids) and the University of Calgary have found that stem cells derived from adult skin can create neural cell types that can be transplanted into and function in mouse models of disease.

Evidence of RNA in structures essential to cell division

Evidence for the first time that centrosomes, which play a key role in cell division, may carry their own genetic machinery, answering a controversial question of long standing.
