Loss of a gene called p63 accelerates aging in mice

Researchers have discovered that the loss of a gene called p63 accelerates aging in mice. Similar versions of the gene are present in many organisms, including humans. Therefore, the p63 gene is likely to play a fundamental biological role in aging-related processes.

Biochemical switch that affects how neurons fire in a part of the brain associated with learning

Researchers at UT Southwestern Medical Center have identified a biochemical switch that affects how neurons fire in a part of the brain associated with learning, findings that may aid in understanding schizophrenia and Alzheimer's disease.

Gene expression levels may reveal stage of Huntington's disease

A survey of the genome of patients with Huntington's Disease (HD) has identified potential markers of the progression of this devastating neurological disorder.

Researchers have discovered a gene linked to age-related maculopathy

University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. Their discovery suggests a simple test might be able to identify those at risk for what is commonly known as macular degeneration (AMD) and may lead to the development of more effective preventive strategies.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Weight control protein may yield new approaches for treating obesity and type 2 diabetes

The findings in mice further suggest that particular variants of the protein SH2-B might underlie obesity in humans, the researchers said.

Breakthrough in human stem cell research

A breakthrough in human stem cell research, producing embryonic-like cells from umbilical cord blood may substantially speed up the development of treatments for life-threatening illnesses, injuries and disabilities.

Adult stem cells may play a role in the development of some forms of cancer

Researchers at UT Southwestern Medical Center have determined that stem cells in a certain region of the brain may be the source of a particular type of incurable brain tumor and may be implicated in other types of brain cancers as well.

Researchers have found evidence that could explain why people continue to sunbathe

Drop by any beach or swimming pool on a summer day, and you'll probably see people doing something they know is bad for them: getting a tan.

Immune system more concerned with damage detected than foreign invaders, such as viruses

A well-respected researcher who is now a chief of an immunology laboratory of the National Institutes of Health (NIH) has rocked the boat in the past few years for the experts in the understanding of the autoimmune system.

Key toxin could provide for world's first treatment for Alzheimer's

Dr Karen Cullen at Sydney University’s Institute for Biomedical Research is part of a collaborative team which has identified a key component in the progression of Alzheimer’s disease, a finding which may produce the world’s first effective treatment to combat the debilitating effects of the disease.

Calcium fights prostate cancer

Calcium, more familiar in its role as one of the building blocks of the body, is being enlisted as a tool in the fight against prostate cancer.

Combined gene therapy eliminates glioblastoma multiforme in lab studies

Despite aggressive treatment, glioblastoma multiforme (GBM) - the most common and deadly of brain cancers - usually claims the lives of its victims within six to 12 months of diagnosis. Because GBM is so aggressive, the disease has been the target of a number of laboratory and clinical studies investigating the effectiveness of gene therapy to deliver novel therapies to the brain.

MiRNA is opening up a whole new way of understanding carcinogenesis

Scientists mining vast, largely unexplored regions of the human genome have identified a small handful of mini-molecules that play a major role in the development of cancer and perhaps many other diseases.

Activated Stat5 protein in prostate cancer can predict outcome, may help target treatment

Researchers from Lombardi Comprehensive Cancer Center at Georgetown University found that testing for an activated Stat5 protein in prostate tumor tissue effectively predicts which men have a form of prostate cancer that may become more aggressive and life threatening.

New gene technique useful for identifying genes and drug targets for diseases such as cancers and diabetes

A collaborative project between American and Chinese researchers developed a way to study the function of genes in mice and man by using a moveable genetic element from moths, according to a report in the journal Cell.

How negatively charged lipids stick to negatively charged DNA and self-organize into structures

Scientists studying the structure and interaction of negatively charged lipids and DNA molecules have created a "cookbook" for a class of nontoxic DNA delivery systems that will assist doctors and clinicians in the safe and effective delivery of genetic medicine.

Researchers have found a signal that could lead to earlier detection and treatment of ovarian cancer

The Penn State team of scientists led by principal investigator Kathleen M. Mulder, Ph.D., professor of pharmacology, and working in conjunction with a researcher from the Center for Cancer Research, National Cancer Institute in Bethesda, Md., studied "km23," a protein that helps to direct protein traffic in the cell.

Oxytocin and ingestive behavior

More than 15 years ago Edward Stricker and Joseph Verbalis reported that oxytocin (OT) is involved in the neural control of food and salt intake in adult rats. Linda Rinaman at the University of Pittsburgh is investigating the anatomical organization of this system, and also is taking a developmental approach to determine how OT modulates eating and digestion.
