Pets also suffer from obesity

It's no secret that obesity is a problem in humans. Reality television makes millions of dollars chronicling the efforts of Americans attempting to shed excess weight.

Study looks at bisphenol A exposure in boys and prostate cancer later in life

Does exposure of baby boys -- in utero or in infancy -- to bisphenol A, a man-made chemical which mimics natural estrogens, predispose them to prostate cancer later in life?

Discovery of gene expression pathway that influences process of oxidative stress

The same chemical reaction that causes iron to rust plays a similarly corrosive role in our bodies.

Genetic and environmental hormonal response to stress in children depends on family context

A study conducted on 346 19-month-old twins by an international team led by Universite Laval professor of psychology Michel Boivin reveals that the genetic and environmental bases of hormonal response to stress depend on the context in which a child grows up.

Mutation in TDP-43 gene may play role in common dementia

Scientists at Washington University School of Medicine in St. Louis have linked a mutation in a gene known as TDP-43 to an inherited form of amyotrophic lateral sclerosis (ALS), the neurodegenerative condition often called Lou Gehrig's disease.

Single microRNA plays role in innate immune response

Over the last few years scientists have discovered hundreds of microRNAs - tiny RNAs that regulate the expression of protein-coding genes.

Scientists shed light on long-distance signaling in developing neurons

A longstanding puzzle in neurodevelopment may have yielded up a key secret.

Researchers examine animal antibiotic resistance, possible human link

It's bad enough when pathogenic bacteria work their way into the animal food supply.

Gene therapy - immune system discovery may lead to effective treatment for glioblastoma multiforme

A new gene therapy approach that attracts and "trains" immune system cells to destroy deadly brain cancer cells also provides long-term immunity, produces no significant adverse effects and -- in the process of destroying the tumor -- promotes the return of normal brain function and behavioral skills, according to a study conducted by researchers at Cedars-Sinai Medical Center's Board of Governors Gene Therapeutics Research Institute.

L-acetyl carnitine effective ADHD treatment for children with fragile X syndrome

Fragile X syndrome (FXS) is the most common hereditary form of mental retardation.

New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

Researchers in a multi-institutional study led by Cincinnati Children's Hospital Medical Center slowed the growth of two particularly stubborn solid tumor cancers - neuroblastoma and peripheral nerve sheath tumors - without harming healthy tissues by inserting instructions to inhibit tissue growth into an engineered virus, according to study results published in the February 15 Cancer Research.

Transplanted cells can cure hemophilia

Scientists at the Albert Einstein College of Medicine of Yeshiva University have shown for the first time that transplanted cells can cure hemophilia A (the most common form of the disease) in an animal model.

Stanford researchers make first direct observation of 3-D molecule folding in real time

All the crucial proteins in our bodies must fold into complex shapes to do their jobs.

Role gound for glaucoma gene and a signaling pathway

Researchers have found that a gene and a related signaling pathway play a role in the development of glaucoma, which is a common cause of visual impairment and blindness worldwide.

Personalized medicine can cut breast cancer risk

The time has come for breast cancer risk assessment, counseling and genetic testing to move from cancer specialists to the realm of primary care, according to a presentation at the AAAS annual meeting, held this year in Boston.

Cholesterol-lowering drug used to block staph infections in mince

An international team of researchers supported by the National Institutes of Health (NIH) has blocked staph infections in mice using a drug previously tested in clinical trials as a cholesterol-lowering agent.

Discovery of new cataract gene

The international team of researchers was able to identify the location and defect in the coding region of the gene through analysis of genetic material (DNA) from members of a large Swiss family, the majority of whom suffered from autosomal dominant juvenile cataract.

Metabolic syndrome linked to climate

Researchers from the University of Chicago have discovered that many of the genetic variations that have enabled human populations to tolerate colder climates may also affect their susceptibility to metabolic syndrome, a cluster of related abnormalities such as obesity, elevated cholesterol levels, heart disease, and diabetes.
