Researchers identify two proteins in cellular response to mechanical stimulation

Scripps Research Institute scientists have identified two proteins with potential to be important targets for research into a wide range of health problems, including pain, deafness, and cardiac and kidney dysfunction.

GABRA2 gene influences brain’s reward responses to alcohol odors: Research

Single nucleotide polymorphisms (SNPs) are DNA sequence variations that occur when a single nucleotide in the genome sequence is altered. Prior research suggested an association between SNPs in a gene that encodes aspects of the brain's gamma-amino butyric acid (GABA)-A receptors (the GABRA2 gene) and alcohol dependence. A study of responses to the aromas of alcoholic drinks according to subjects' genotyping at a SNP in GABRA2 has found that this genotype can affect the brain's reward responses to cues such as alcohol odors.

International consortium publishes third-generation map of human genetic variation

An international consortium today published a third-generation map of human genetic variation, called the HapMap, which includes data from an additional seven global populations, increasing the total number to 11 populations. The improved resolution will help researchers interpret current genome studies aimed at finding common and rarer genetic variants associated with complex diseases.

New hybrid proteins may lead to better gene replacement and editing therapies

An Iowa State University team of researchers has developed a type of hybrid proteins that can make double-strand DNA breaks at specific sites in living cells, possibly leading to better gene replacement and gene editing therapies.

'Molecular Diagnostics Europe' conference debuts at BIOTECHNICA 2010

BIOTECHNICA, Europe's Leading Exhibition for Biotechnology and Life Sciences, is broadening its portfolio to include a new conference and special display on molecular diagnostics. Produced by the Cambridge Healthtech Institute, a leading organizer of biomedical conferences in the United States, the "Molecular Diagnostics Europe" (MDxEU) conference is making its debut this year. The main focus will be on new methods for molecular diagnostics, particularly with regard to cancer and infectious diseases.

Light signaling pathways, circadian rhythms affect biological functions: Research

A new study of the genetic basis of circadian rhythms - the biological responses related to daily light exposure - has found that a few minutes of light exposure in a fungus directly affects a huge range of its biological functions, everything from reproduction to coloring and DNA repair.

Ambry Genetics acquires Illumina HiSeq 2000 Sequencing and BeadXpress Genotyping systems

Ambry Genetics, a global leader in genomic services, announced today that it has acquired the Illumina HiSeq 2000 Next Generation Sequencing System as well as received the first 510(K) approved Illumina BeadXpress Genotyping System. Ambry Genetics has been an early adapter of Illumina systems since late 2007 and has extensive experience as a Certified Service Provider.

Scientists discover influence of vitamin D in genes linked with autoimmune diseases

UK scientists at the University of Oxford have discovered that vitamin D can affect the activity of more than 200 genes of cells grown in the lab. Some of these genes are known from previous studies to be involved in diseases like diabetes and cancer.

Researchers find gene sequences of MLV in chronic fatigue syndrome patients' blood samples

Researchers have found murine leukemia viruses (MLV) related gene sequences in blood samples collected from patients diagnosed with chronic fatigue syndrome (CFS) and some healthy blood donors, according to a study published online today by the scientific journal Proceedings of the National Academy of Sciences (PNAS).

Scientists discover genetic flaw that causes facioscapulohumeral muscular dystrophy

Nearly two decades after they identified the specific genetic flaw that causes a common type of muscular dystrophy, scientists believe they have figured out how that flaw brings about the disease. The finding by an international team of researchers settles a longstanding question about the roots of facioscapulohumeral muscular dystrophy or FSHD.

Maternal stress contribute to an elevated risk for depression in offspring: Research

For more than a century, clinical investigators have focused on early life as a source of adult psychopathology. Although the hypothesized mechanisms have evolved, a central notion remains: early life is a period of unique sensitivity during which experience confers enduring effects.

New DNA sequencing method can lead to effective individualized medicine

In experiments with potentially broad health care implications, a research team led by a University of Washington physicist has devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively.That could open the door for more effective individualized medicine, for example providing blueprints of genetic predispositions for specific conditions and diseases such as cancer, diabetes or addiction.

Researchers discover genetic alterations responsible for Kabuki syndrome

Using a new, rapid and less expensive DNA sequencing strategy, scientists have discovered genetic alterations that account for most cases of Kabuki syndrome, a rare disorder that causes multiple birth defects and mental retardation. Instead of sequencing the entire human genome, the new approach sequences just the exome, the 1-2 percent of the human genome that contains protein-coding genes.

UCSF researchers discover new technology purifying special types of stem cells

UCSF researchers are reporting the first success in very rapidly purifying one type of embryonic stem cell from a mix of many different types of embryonic stem cells in the culture dish. The technique, which avoids the need to genetically alter the cells to distinguish them, is a key advance, the researchers say, for obtaining the appropriate cells for repairing specific damaged tissues.

Scientists suggest home genetic tests may cause unnecessary stress

In the age of the Internet, where cybercondriacs are just a mouse click away from a diagnosis, do-it-yourself home genetics test may seem like the next logical step in managing health. But these tests, which are relatively new and available online, are often not comprehensive and may cause unnecessary stress, warns Suzanne Mahon, DNSc., a clinical professor of hematology and oncology at Saint Louis University.

Self assembly approaches to improve DNA sequencing

In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers.Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand times smaller than the diameter of a human hair. They are used as sensors to detect and characterize DNA, RNA and proteins. But these materials shoot through such holes so rapidly that sequencing the DNA passing through them, for example, is a problem.

Scientists develop carbon based nanoscale to detect single DNA molecules

Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.The pores, burned into graphene membranes using electron beam technology, provide Penn physicists with electronic measurements of the translocation of DNA.

HTG patients face increased risk for heart disease, stroke: Study

It can make blood look like cream of tomato soup. Patients with high levels of triglycerides in their blood, a disease called hypertriglyceridemia face an increased risk for heart disease and stroke. HTG affects one in 20 people in North America and is also associated with obesity, diabetes and pancreatitis. Most people now understand the importance of LDL, the bad cholesterol and HDL, the good cholesterol, to their overall health.
