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).

Aristolochic acid exposure leads to kidney failure and UUC

Aristolochic acid (AA), a component of a plant used in herbal remedies since ancient times, leads to kidney failure and upper urinary tract cancer (UUC) in individuals exposed to the toxin.

Berries may reduce Parkinson’s disease risk in men: Study

A new study has found that men who regularly consume foods rich in flavonoids, such as berries, apples, certain vegetables, tea and red wine, may significantly reduce their risk for developing Parkinson's disease. The study was published in the journal Neurology this week. It added that there was no such effect among women.

Sperm donor found to have fathered 600 babies

Bertold Wiesner and Mary Barton’s controversial clinic for high IQ donors helped women conceive more than 1,500 babies. Now two of the children conceived from the clinic discovered they are Wiesner’s biological sons and have found that he fathered hundreds of other children.

Five significant genetic associations for hypothyroidism found

Using its unique online research platform, 23andMe, a leading personal genetics company, has found five significant genetic associations for hypothyroidism in the largest known genome-wide association study of hypothyroidism conducted to date. The details of the study are now available online in the journal PLoS ONE.

Heart cells starved of nutrients less likely to be damaged during ischemia, reperfusion

Heart cells starved of nutrients are less likely to be damaged during periods of decreased blood flow and sudden influxes of blood, known as ischemia and reperfusion, and are also less likely to get out of synch with their cellular neighbors, the damaging phenomenon called arrhythmia.

Scientists discover novel genes that are mutated in stomach cancer

An international team of scientists, led by researchers from the Duke-NUS Graduate Medical School (Duke-NUS) in Singapore and National Cancer Centre of Singapore, has identified hundreds of novel genes that are mutated in stomach cancer, the second-most lethal cancer worldwide.

Research on how cells cope with stress could lead to more effective cancer treatment

Both radiation and many forms of chemotherapy try to kill tumors by causing oxidative stress in cancer cells. New research from USC on a protein that protects cancer and other cells from these stresses could one day help doctors to break down cancer cells' defenses, making them more susceptible to treatment.

New technique reveals another piece of spectrum's genetic architecture

There is little argument among experts that autism spectrum disorders (ASD), complex developmental disabilities that vary widely in their severity, are caused by both genetic and environmental factors. Advances in genome sequencing now permit scientists to uncover specific mutations in DNA that are associated with ASD at unprecedented resolution. Such data are vital to understanding the genetic basis of the disorder.

Gold nanostars can deliver drug directly to cancer cell nucleus

Nanotechnology offers powerful new possibilities for targeted cancer therapies, but the design challenges are many. Northwestern University scientists now are the first to develop a simple but specialized nanoparticle that can deliver a drug directly to a cancer cell's nucleus -- an important feature for effective treatment.

PTSD could be genetically predicted

PTSD can occur after any kind of experience that causes trauma, whether that be in war, after a natural disaster or because of child abuse or sexual assault. Symptoms can include flashbacks, feeling emotionally numb or hyper-alert to danger, and avoiding situations that act as reminders of the original trauma. It is estimated that up to 3% of the general population is likely to be affected by PTSD at some point.

Gene mutations, age of parents and autism

New research shows that several gene mutations sharply increase the chances that a child will develop autism spectrum disorders. The researchers have found further evidence that the risk increases with the age of the parents, particularly in fathers over age 35.
