DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Gene variations likely to have important effects on gene function: Study

Everyone is special in their own unique way. From a genetic point of view, no two humans are genetically identical. This means that DNA for each individual contains variants that are more or less comm. on in the overall population.

Chronix Biomedical expands biomarker development capabilities with installation of DNA mass sequencer

Chronix Biomedical today reported that it has significantly expanded and accelerated its biomarker development capabilities with the installation of Germany's first state-of-the-art high-throughput DNA mass sequencer at the University of Göttingen, Chronix's long-time collaborator. Chronix is developing disease-specific biomarkers based on DNA fragments that are released into the bloodstream by damaged and dying (apoptotic) cells.

Air quality along US Gulf Coast improves after stoppage of oil leak

The oil spill along the United States Gulf Coast poses health risks to volunteers, fishermen, clean-up workers and members of coastal communities, according to a new commentary by UCSF researchers who spent time in the region and are among the first to look into health problems caused by the oil spill. The good news, the authors say, is that one of the risk factors, coastal air quality, is improving now that the oil leak has been stopped.

Diets rich in antioxidants, omega-3 fatty acids can help protect people from skin cancer: Study

We all want that summer glow that comes from a day at the beach, but taking in the rays can have long-term implications for our health. Now Dr. Niva Shapira of Tel Aviv University's School of Health Professions suggests a way to make fun in the sun safer ― and it's all in our food.

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.

Experimental drug benefits women with advanced ovarian or breast tumours caused by BRCA gene faults

An experimental drug called olaparib has been shown to shrink tumours in women whose advanced cancers were caused by faults in their BRCA genes.

Scientists identify possible therapeutic strategy for reducing leukemia risk from chemotherapy

A UCSF-led team has discovered at least one key reason why blood stem cells are susceptible to developing the genetic mutations that can lead to adult leukemia. Their finding also may explain, they say, why some other age-related hematological disorders develop.The study, reported in "Cell Stem Cell" and reviewed in Cell Stem Cell and Cell, opens a new frontier for studying the molecular underpinnings of adult leukemia.

Study finds abnormal expression of miRNAs can contribute to human diseases

Researchers at Tufts University School of Medicine and Tufts Medical Center have identified an RNA sequence that promotes increased numbers of specific microRNAs (miRNAs), molecules that regulate cell growth, development, and stress response. The discovery helps researchers understand the links between miRNA expression and disease, including heart disease and cancer. The findings are published in the August 13 issue of Molecular Cell.

Scientists find epigenetic landscape map for tissue differentiation

Having charted the occurrence of a common chemical change that takes place while stem cells decide their fates and progress from precursor to progeny, a Johns Hopkins-led team of scientists has produced the first-ever epigenetic landscape map for tissue differentiation.The details of this collaborative study between Johns Hopkins, Stanford and Harvard appear August 15 in the early online publication of Nature.

Non-viral gene therapy delays onset of eye disease

In one of only two studies of its kind, a study from researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts demonstrates that non-viral gene therapy can delay the onset of some forms of eye disease and preserve vision. The team developed nanoparticles to deliver therapeutic genes to the retina and found that treated mice temporarily retained more eyesight than controls.

SIK2 impacts cell division cycle, regulates ovarian cancer response to chemotherapy: Research

For the first time, Salt Inducible Kinase 2 (SIK2) has been found to play a critical role in cell division and to regulate the response of some ovarian cancers to chemotherapy.Findings were reported by researchers from The University of Texas MD Anderson Cancer Center in the August issue of Cancer Cell. The study adds to growing evidence that combination therapies targeting different phases of the cell division cycle are vital for optimal cancer treatment.

Scientists identify genes associated with aggressive breast cancer

Researchers at the University of Gothenburg, Sweden, have for the first time identified 12 genes that could be associated with aggressive breast tumours. The discovery could result in more reliable prognoses and better treatment strategies for patients.

MeCP2 protein regulates properties of psychostimulant drugs: Research

When a certain protein is mutated or missing, symptoms of the neurodevelopmental disorder Rett syndrome arise, causing a gradual loss of brain function during early development.This fact led Duke University Medical Center researchers to test a theory that the protein might also contribute to nerve-cell connection (synapse) changes in a fully formed adult mouse brain when exposed to psychostimulant use.

Adverse effects in childhood lead to immune impairment later in life

The emotional pains we suffer in childhood can lead to weakened immune systems later in life, according to a new study.Based on this new research, the amount of this immune impairment even enhances that caused by the stress of caregiving later in life."What happens in childhood really matters when it comes to your immune response in the latter part of your life," explained Janice Kiecolt-Glaser, professor of psychology and psychiatry at Ohio State University. She explained her work at the annual meeting of the American Psychological Association in San Diego.

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.
