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).

LabCorp, UnitedHealthcare extend partnership

Laboratory Corporation of America Holdings announced today that it has extended the term of its agreement with UnitedHealthcare Insurance Company, an affiliate of UnitedHealth Group Incorporated for an additional two years. The agreement, which was effective January 1, 2007, will now continue through the end of 2018.

Dysregulated neuronal RNA transport may cause Fragile X-associated tremor/ataxia syndrome

SUNY Downstate scientist Ilham Muslimov, MD, PhD, along with senior author Henri Tiedge, PhD, professor of physiology and pharmacology and of neurology, published a study suggesting that cellular dysregulation associated with certain neurodegenerative disorders may result from molecular competition in neuronal RNA transport pathways.

Biochemists reveal interaction between tumor suppressor protein and chaperone

Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.

New surprising discovery on division of mitochondria within cells

A surprising new discovery by the University of Colorado Boulder and the University of California, Davis regarding the division of tiny "power plants" within cells known as mitochondria has implications for better understanding a wide variety of human diseases and conditions due to mitochondrial defects.

London scientist hopes to improve diagnosis for Jeune syndrome

A London scientist is hoping a new study funded by children's charity Action Medical Research, will help to improve diagnosis and work towards new treatments for a rare, incurable genetic disorder called Jeune syndrome.

Researchers discover new genetic defect that can lead to Leigh syndrome

In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of 3. The problem is that the mitochondria responsible for powering their cells can't keep up with the demand for energy in their developing brains.

Researchers discover novel way to increase amounts of antibiotics

A novel way of increasing the amounts of antibiotics produced by bacteria has been discovered that could markedly improve the yields of these important compounds in commercial production. It could also be valuable in helping to discover new compounds. With the ever-growing threat from antibiotic resistance, these tools will be very useful in ensuring that we have enough of these useful compounds in the future.

'Shan Song' finds new way of processing non-genetically modified soybeans

How much did you know about soybeans? How did you find the difference between GM soybeans and non-GM soybeans? How can people find the 'New Market' for traditional non-GM soybeans? You may get the answer if you knew 'Shan Song'.

Cancer cells with specific genetic defect extra susceptible to therapy that damages DNA

Using a strategy based on treating cancer cells that carry a specific genetic signature - hyper-expression of the protein Myc - with therapy that affects the stability of the cell's DNA, more effective results can be achieved.

Scientists purify PARP protein that shows promise against breast, ovarian cancers

CANCER RESEARCH UK scientists have succeeded in purifying a protein found in bacteria that could reveal new drug targets for inherited breast and ovarian cancers - and other cancers linked to DNA repair faults.

C. sporogenes bacterium could be used as vehicle to deliver drugs in frontline cancer therapy

A bacterial strain that specifically targets tumours could soon be used as a vehicle to deliver drugs in frontline cancer therapy. The strain is expected to be tested in cancer patients in 2013 says a scientist at the Society for General Microbiology's Autumn Conference at the University of York.

Researchers discover new genetic defect that predisposes people to leukemia, myelodysplasia

A new genetic defect that predisposes people to acute myeloid leukemia and myelodysplasia has been discovered. The mutations were found in the GATA2 gene. Among its several regulatory roles, the gene acts as a master control during the transition of primitive blood-forming cells into white blood cells.

Scientists discover highly conserved mechanism governing brain development

If you think today's political rhetoric is overheated, imagine what goes on inside a vertebrate embryo. There, two armies whose agendas are poles apart, engage in a battle with consequences much more dire than whether the economy will recover---- they are battling for whether you (or frogs or chickens) will have a forebrain.
