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).

New mouse study indicates that mutant protein in muscle cells is responsible for SBMA

Sometimes known as Kennedy's disease, spinal and bulbar muscular atrophy (SBMA) is a rare inherited neuromuscular disorder characterized by slowly progressive muscle weakness and atrophy.

Viewpoints: Obamacare dilemma -- some people dislike the law but embrace its provisions; are health costs falling?

Polls have consistently shown that even though the public opposes Obamacare, people like some of its most significant provisions. That's particularly true of the requirement that insurers ignore preexisting conditions when signing up customers for coverage.

Optimal use of combination therapy achieves best treatment outcomes in patients with CHB

Three new studies presented today at the International Liver CongressTM 2014 have helped clarify the optimal use of combination therapy with peginterferon and nucleoside analogues (NUCs) to achieve the best treatment outcomes in patients with chronic hepatitis B (CHB).

Protein expression predicts postop NSCLC recurrence, survival

US-based researchers have identified a panel of 12 proteins that may help predict overall survival and the risk of recurrence in patients treated with surgery for non-small-cell lung cancer.

Daylight Medical releases SKY 6Xi disinfection technology for mobile devices

Daylight Medical, manufacturer and provider of innovative medical products, is pleased to announce its rollout of SKY 6Xi, disinfection technology for mobile devices. SKY 6Xi uses high intensity (254 nanometer wavelength) ultraviolet light in the "C" spectrum (UVC) at close proximity to thoroughly disinfect a mobile device. The unique power of SKY reduces the risk that Hospital-acquired infections (HAIs) are transmitted to patients while improving safety for healthcare workers.

New blood test accurately detects presence of breast cancer and monitors response to treatment

Johns Hopkins Kimmel Cancer Center investigators report they have designed a blood test that accurately detects the presence of advanced breast cancer and also holds promise for precisely monitoring response to cancer treatment.

New technique of single-cell genomic analysis to reverse tissue engineering

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body.

Engineers develop tools to efficiently analyze living cells

For more than a decade Chang Lu, associate professor of chemical engineering at Virginia Tech, has worked on the development of tools to efficiently analyze living cells. The long-term goal is to gain a better understanding of a range of diseases.

Bio-Rad Laboratories buys GnuBIO

GnuBIO, a privately-held life sciences company that has developed a droplet-based DNA sequencing technology, today announced that it was acquired by Bio-Rad Laboratories, Inc. With this acquisition, Bio-Rad will expand its Digital Biology Center and establish a research and development site in Cambridge, Massachusetts.

1/4 human tumor exist genetic polymorphisms linked with increased risk of cancer

In 10% of human tumors there is a family history of hereditary disease associated with mutations in identified genes. The best examples are the cases of polyps in the large intestine associated with the APC gene and breast cancer associated with BRCA1 and BRCA2 genes.

Researchers develop novel assay to identify genes controlling pharynx regeneration in flatworms

As multicellular creatures go, planaria worms are hardly glamorous. To say they appear rudimentary is more like it. These tiny aquatic flatworms that troll ponds and standing water resemble brown tubes equipped with just the basics: a pair of beady light-sensing "eyespots" on their head and a feeding tube called the pharynx (which doubles as the excretory tract) that protrudes from a belly sac to suck up food.

Tumor-suppressing protein acts as dimmer switch to dial down gene expression

A tumor-suppressing protein acts as a dimmer switch to dial down gene expression. It does this by reading a chemical message attached to another protein that's tightly intertwined with DNA, a team led by scientists at The University of Texas MD Anderson Cancer Center reported at the AACR Annual Meeting 2014.

Comprehensive genomic analysis of low-grade brain tumors sorts into three categories

Comprehensive genomic analysis of low-grade brain tumors sorts them into three categories, one of which has the molecular hallmarks and shortened survival of glioblastoma multiforme, the most lethal of brain tumors, researchers reported at the American Association for Cancer Research Annual Meeting 2014.

Scientists design new system for molecular blood group typing

Scientists in France have designed a new system for molecular blood group typing that offers blood banks the possibility of extensive screening of blood donors at a relatively low cost. Their approach is described in the current issue of The Journal of Molecular Diagnostics.

Stressful upbringings can leave imprints on genes of African American children

Stressful upbringings can leave imprints on the genes of children as young as age 9, according to a study led by Princeton University and Pennsylvania State University researchers. Such chronic stress during youth leads to physiological weathering similar to aging.

Multiple genomic data could help improve studies of association between genes and disease

The difference between merely throwing around buzzwords like "personalized medicine" and "big data" and delivering on their medical promise is in the details of developing methods for analyzing and interpreting genomic data. In a pair of new papers, Brown University epidemiologist Yen-Tsung Huang and colleagues show how integrating different kinds of genomic data could improve studies of the association between genes and disease.
