Zebrafish model can test unique individual genetic differences in humans

The zebrafish is a potential tool for testing one class of unique individual genetic differences found in humans, and may yield information helpful for the emerging field of personalized medicine, according to a team led by Penn State College of Medicine scientists. The differences, or mutations, in question create minor changes in amino acids -- the building blocks of DNA -- from person to person.

Feinstein Institute to study overall impact of WTC disaster on responders

The Feinstein Institute for Medical Research has been awarded a $1 million grant from the World Trade Center Health Program, which is administered by the National Institute for Occupational Safety and Health, part of the US Centers for Disease Control and Prevention, the National Institute for Occupational Safety and Health and Safety to comprehensively study the overall physical, mental and socioeconomic impact of the World Trade Center (WTC) disaster on responders, as well as identify the linkage between socioeconomic status and health among all occupations of WTC responders.

HCFC1 protein may cause intellectual disability

Genetics researchers at the University of Adelaide have solved a 40-year mystery for a family beset by a rare intellectual disability - and they've discovered something new about the causes of intellectual disability in the process.

Researchers discover genetic biomarker for age-related hearing loss

University of South Florida researchers have identified a genetic biomarker for age-related hearing loss, a major breakthrough in understanding and preventing a condition of aging that affects 30 million Americans and greatly diminishes their quality of life.

Scientists create yellow potatoes with high carotenoid levels

Potatoes with higher levels of beneficial carotenoids are the result of U.S. Department of Agriculture (USDA) studies to improve one of America's most popular vegetables.

Three new gene variants associated with BMI levels in adults

A large international study has identified three new gene variants associated with body mass index (BMI) levels in adults. The scientific consortium, numbering approximately 200 researchers, performed a meta-analysis of 46 studies, covering gene data from nearly 109,000 adults, spanning four ethnic groups.

Paper details new target for anti-cancer drug development

In a new paper released today in Nature, BioFrontiers Institute scientists at the University of Colorado Boulder, Tom Cech and Leslie Leinwand, detailed a new target for anti-cancer drug development that is sitting at the ends of our DNA.

UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

New biomarker measures aggressiveness of primary prostate tumors

Research out of Roswell Park Cancer Institute (RPCI) supports the adoption of a new biomarker to measure the aggressiveness of primary prostate tumors.

Novel approach to assemble the 'connectome' via genetic barcoding

A team of neuroscientists has proposed a new and potentially revolutionary way of obtaining a neuronal connectivity map (the "connectome") of the whole brain of the mouse. The details are set forth in an essay published October 23 in the open-access journal PLOS Biology.

Link between autism spectrum disorders and schizophrenia

Autism Spectrum Disorders (ASD), a category that includes autism, Asperger Syndrome, and Pervasive Developmental Disorder, are characterized by difficulty with social interaction and communication, or repetitive behaviors. The U.S. Centers for Disease Control and Management says that one in 88 children in the US is somewhere on the Autism spectrum - an alarming ten-fold increase in the last four decades.

Austrian researchers receive $7.4 million award to verify new breast cancer pathways

The innovator's award recognises Josef Penninger's work in identifying a key molecular pathway how hormone replacement therapies and contraceptive pills can lead to breast cancer. His team provided the first genetic proof that a protein called RANKL is the master regulator of bone loss, which has contributed to the development of a novel drug already approved for the treatment of osteoporosis and skeletal related events in multiple cancers.

Breast cancer spread dependent on both environment and genetic changes

A new study from Johns Hopkins researchers suggests that the lethal spread of breast cancer is as dependent on a tumor’s protein-rich environment as on genetic changes inside tumor cells.

Thin ideal internalization: an interview with Jessica Suisman and Kelly Klump

Thin-ideal internalization is the extent to which a person identifies with the cultural ideal that thinness is equivalent to attractiveness.

Glioblastoma multiforme can originate from cortical neurons

Scientists have long believed that glioblastoma multiforme (GBM), the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. In a paper published October 18 in Science Express, however, researchers at the Salk Institute for Biological Studies have found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.

New approach to prevention of breast cancer wins $7.4M award

A new approach to possible future prevention of breast cancer and slowing the spread of tumours has won Austrian researcher Josef Penninger, director of the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) in Vienna, a $7.4 million innovator's award to continue his research, from the USA's Congressionally Directed Medical Research Program.

Insight into calcium pumps in cells

When animals and plants are exposed to influences such as bacterial attack, odour and cold, calcium ions flow into the cells. The calcium provides the cells with a signal about what is going on outside, but as high concentrations of calcium are toxic to the cells, it must be quickly pumped out again.

Epigenetic alteration associated with increased risk of breast cancer

Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is called "twin discordance". But how can people who have the same genetic sequence present different pathologies and at different ages? The explanation partly lies in the fact that the chemical signals added in the DNA to "switch off" or "switch on" genes can be different. These signals are known as epigenetic marks.

AMP report provides overview of next generation sequencing technology

The Association for Molecular Pathology published the report of the Whole Genome Analysis Working Group of the AMP Clinical Practice Committee in the November 2012 issue of The Journal of Molecular Diagnostics.

Common misconceptions about breast cancer risks

From the food we eat to the products we use, there are a lot of misconceptions about what may increase the risk of developing breast cancer. There are known factors, like genetics, that are well documented. But what about lifestyle issues like having a nightly cocktail or using deodorant? So, what is fact and what is fiction? Wendy Chen, MD, MPH, a breast cancer expert at Dana-Farber Cancer Institute in Boston says an overabundance of information can be confusing, and it often is incorrect to some degree.
