Study helps explain how large DNA viruses undergo rapid evolution

Scientists have discovered that poxviruses, which are responsible for smallpox and other diseases, can adapt to defeat different host antiviral defenses by quickly and temporarily producing multiple copies of a gene that helps the viruses to counter host immunity.

New DNA sequencing tests improve ability to analyze genetic disorders

Scientists at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School (UMDNJ-NJMS) have developed new DNA sequencing tests that hold significant promise for decreasing costs associated with diagnosing cancer and hereditary diseases, including cysticfibrosis.

Study reveals why human brain is large and more complex than that of other animals

Researchers have found what they believe is the key to understanding why the human brain is larger and more complex than that of other animals.

Rhomboid enzymes and malaria treatment: an interview with Sinisa Urban

Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.

Researchers discover why people with sickle cell disease get milder cases of malaria

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells.

Two papers may help identify gene variants that contribute to OCD or Tourette syndrome

Two papers that will appear in the journal Molecular Psychiatry, both receiving advance online release, may help identify gene variants that contribute to the risks of developing obsessive-compulsive disorder (OCD) or Tourette syndrome (TS). Both multi-institutional studies were led by Massachusetts General Hospital (MGH) investigators, and both are the first genome-wide association studies (GWAS) in the largest groups of individuals affected by the conditions.

New tool reveals surprising clues about how cancer cells respond to therapy

A new tool to observe cell behavior has revealed surprising clues about how cancer cells respond to therapy - and may offer a way to further refine personalized cancer treatments.

Protein folding: Nobel laureate Ahmed H. Zewail summarizes his insights

Living subjects are very complex systems and, at the same time, stunningly robust and accommodative. The secret of success are their proteins which build up the cells of the organisms, act as cleaners, messengers, transporter, motors, and fulfill much more jobs. How proteins are genetically coded and how their linear chains of amino acids are put together, is in principle well known.

Schizophrenia and the immune system: an interview with Prof Cyndi Shannon Weickert

Schizophrenia is the most disabling disease impacting youth today. It impacts 1% of the total population and typically causes withdrawal from society, loss in IQ, disordered thought and speech, hallucinations and delusions.

Researchers identify key element in the development of Burkitt lymphoma

Burkitt lymphoma is a malignant, fast-growing tumor that originates from a subtype of white blood cells called B lymphocytes of the immune system and often affects internal organs and the central nervous system. Now Dr. Sandrine Sander and Professor Klaus Rajewsky of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have identified a key element that transforms the immune cells into malignant lymphoma cells.

Scientists identify new genetic alterations underlying high-risk subtype of ALL

Scientists have identified new genetic alterations underlying a high-risk subtype of the most common childhood cancer that could be effectively targeted with existing leukemia therapies.

Researchers identify new gene in Cornelia deLange syndrome

Genetics researchers have identified a key gene that, when mutated, causes the rare multisystem disorder Cornelia deLange syndrome (CdLS). By revealing how mutations in the HDAC8 gene disrupt the biology of proteins that control both gene expression and cell division, the research sheds light on this disease, which causes intellectual disability, limb deformations and other disabilities resulting from impairments in early development.

Fluorescent molecules 'tag' DNA and monitor looping process

In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells.

Researchers discover gene mutations linked to spinocerebellar ataxia

A global hunt for the cause of a crippling inherited nerve disorder has found its target. The discovery opens the door for better diagnosis and treatment of this particular disease - but also for better understanding of why nerves in the brain's movement-controlling center die, and how new DNA-mapping techniques can find the causes of other diseases that run in families.

Johns Hopkins CIDR receives NIH contract to study genetic diseases

The Johns Hopkins Center for Inherited Disease Research (CIDR) program contract, which provides up to $101 million in research funding from the National Institutes of Health (NIH) to study the genetic contribution to human diseases, has been renewed for another five years.

Research focuses on evolution of sex and gamete function

The propagation of every animal on the planet is the result of sexual activity between males and females of a given species. But how did things get this way? Why two sexes instead of one? Why are sperm necessary for reproduction and how did they evolve? These as-yet-unresolved issues fascinate Timothy Karr, a developmental geneticist and evolutionary biologist at Arizona State University's Biodesign Institute.

Scientists discover how pten gene causes brain changes that lead to autism-like behavior

Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Reducing copper in the body delays onset of prion disease

Many of us are familiar with prion disease from its most startling and unusual incarnations-the outbreaks of "mad cow" disease (bovine spongiform encephalopathy) that created a crisis in the global beef industry. Or the strange story of Kuru, a fatal illness affecting a tribe in Papua New Guinea known for its cannibalism. Both are forms of prion disease, caused by the abnormal folding of a protein and resulting in progressive neurodegeneration and death.
