ParseCNV software can detect disease-causing copy number variations

A novel software tool, developed at The Children's Hospital of Philadelphia, streamlines the detection of disease-causing genetic changes through more sensitive detection methods and by automatically correcting for variations that reduce the accuracy of results in conventional software.

Brown biology professor named Pew's Scholar of the Month

Biologist Erica Larschan, Ph.D., was named by The Pew Charitable Trusts as the "Scholar of the Month," for her innovative findings on chromosomal activity in fruit flies.

New special issue explores link between evolution and the body's fight against cancer

Over 500 billion cells in our bodies will be replaced daily, yet natural selection has enabled us to develop defenses against the cellular mutations which could cause cancer. It is this relationship between evolution and the body's fight against cancer which is explored in a new special issue of the Open Access journal Evolutionary Applications.

Rainbow Coral visits genome-mapping facility in Houston

Since the new year began, Rainbow Coral Corp. has wasted no time in searching for new targets to add to its portfolio of projects for commercialization. Last week, the Company's executive leadership accepted an invitation to tour a genome-mapping facility in Houston with which RBCC could soon partner.

Family members with rare gene mutation at high risk of developing schizophrenia

Johns Hopkins researchers have identified a rare gene mutation in a single family with a high rate of schizophrenia, adding to evidence that abnormal genes play a role in the development of the disease.

Study indicates rate of ADHD diagnosis has increased from 2001 to 2010

A study of medical records at the Kaiser Permanente Southern California health plan suggests the rate of attention-deficit/hyperactivity disorder (ADHD) diagnosis increased from 2001 to 2010, according to a report published Online First by JAMA Pediatrics, a JAMA Network publication.

Study reveals ugly cholesterol is the direct cause of ischaemic heart disease

The risk of ischaemic heart disease - a disease affecting some 150,000 Danes - is three times higher in persons with high levels of the so-called 'ugly' cholesterol. This is the finding of a new study of 73,000 Danes, which is shedding light on a long debate on this topic. The results have just been published in the Journal of the American College of Cardiology.

New DNA chip could improve diagnosis and therapeutics of ADHD

Attention Deficit Hyperactivity Disorder (ADHD) is the most common childhood neuropsychiatric disorder. Yet there is currently no tool that will confirm the diagnosis of ADHD. In her thesis entitled "Development of a genotyping system to be applied in Attention Deficit Hyperactivity Disorder and its Pharmacogenetics".

Winning the genetic body odor lottery could save on deodorant

Research shows that people who have two copies of the minor allele of a single nucleotide polymorphism found in the ABCC11 gene could save money on deodorant as they are genetically odorless.

Itch-specific nerve cells: an interview with Associate Professor Xinzhong Dong

Itch was actually defined by a German physician more than 350 years ago. His name was Samuel Hafenreffer. He defined itch as an unpleasant sensation that makes people want to scratch. You probably think this is a very simple definition but itch is really a very complex sensory modality.

Scientists discover role of OTUD7B enzyme as TRAF3's protector

Marked for death with molecular tags that act like a homing signal for a cell's protein-destroying machinery, a pivotal enzyme is rescued by another molecule that sweeps the telltale targets off in the nick of time.

Scientists identify a possible lead in treatment of two childhood leukemia subtypes

Research led by St. Jude Children's Research Hospital scientists has identified a possible lead in treatment of two childhood leukemia subtypes known for their dramatic loss of chromosomes and poor treatment outcomes.

Study refocuses on how neuroblastoma tumors evolve in response to medicine and other factors

An extensive genomic study of the childhood cancer neuroblastoma reinforces the challenges in treating the most aggressive forms of this disease. Contrary to expectations, the scientists found relatively few recurrent gene mutations—mutations that would suggest new targets for neuroblastoma treatment. Instead, say the researchers, they have now refocused on how neuroblastoma tumors evolve in response to medicine and other factors.

Researchers identify clear role for tags in mediating genetic risk for rheumatoid arthritis

In one of the first genome-wide studies to hunt for both genes and their regulatory "tags" in patients suffering from a common disease, researchers have found a clear role for the tags in mediating genetic risk for rheumatoid arthritis (RA), an immune disorder that afflicts an estimated 1.5 million American adults.

Law banning genetic discrimination doesn't apply to some insurers

NPR examines a key loophole in the law designed to keep health insurers from raising rates or denying coverage because of genetic issues. The law doesn't apply to life, disability or long-term-care insurance.

Stage IV cancer cells even more susceptible to grape seed extract than stage II

When the going gets tough, grape seed extract gets going: A University of Colorado Cancer Center study recently published in the journal Cancer Letters shows that the more advanced are colorectal cancer cells, the more GSE inhibits their growth and survival. On the other end of the disease spectrum, GSE leaves healthy cells alone entirely.

Intestinal bacteria can produce biochemicals and hormones that stop development of diabetes

All humans have enormous numbers of bacteria and other micro-organisms (10 to 14) in the lower intestine. In fact our bodies contain about ten times more bacteria than our own cells and these tiny passengers are extremely important for our health. They help us digest our food and provide us with energy and vitamins.

UC Davis professor receives supplemental funds from Parent Project Muscular Dystrophy

Parent Project Muscular Dystrophy (PPMD) has awarded Dr. Craig McDonald of the University of California, Davis (UC Davis) $175,000 in supplemental funds to expand his ongoing study through the 20 CINRG (Cooperative International Neuromuscular Research Group) centers to better understand the progression of Duchenne muscular dystrophy (Duchenne) and determine the impact of the Duchenne standards of care established by the Centers for Disease Control (CDC).

SPARC protein acts much like ibuprofen to heal tissues inflamed by tumors

Cancer researchers are increasingly aware that in addition to genetic mutations in a cancer itself, characteristics of the surrounding tissue can promote or suppress tumor growth. One of these important tissue characteristics is inflammation - most cancers prosper in and attach to inflamed tissue and so many cancers have developed ways to create it.

Researchers identify signaling pathway used by malarial parasites to destroy host cells

One of the most insidious ways that parasitic diseases such as malaria and toxoplasmosis wreak their havoc is by hijacking their host's natural cellular processes, turning self against self.
