Around one in 20 men is infertile, but despite the best efforts of scientists, in many cases the underlying causes of infertility have remained a mystery. New findings by a team of Australian and Swedish researchers, however, will go a long way towards explaining this mystery. According to their research published in Science today, a small set of genes located within the power-plants of our cells "“ the mitochondria "“ are crucial to unravelling the secrets of male infertility....

(Ivanhoe Newswire) -- A specific genetic defect in one Chinese family shows that high blood pressure was inherited from the mother. The defect results from the substitution of a single DNA "base" for another during replication in the genes of a tiny cellular organ called the mitochondria, which generates a cell's energy. When reproductive cells come together to form an embryo, the mitochondrial DNA from the mother cell is passed on to the offspring. Evidence has suggested a mother-child...

American Heart Association rapid access journal report A specific genetic defect in one Chinese family shows that high blood pressure was inherited from the female parent, researchers report in Circulation Research: Journal of the American Heart Association. The defect results from a point mutation "” the substitution of a single DNA "base" for another during replication "” in the genes of a tiny cellular organ called the mitochondria, which generates a cell's energy. When...

A fertility treatment designed to prevent some incurable inherited diseases, opens the possibility that children could be conceived from three biological parents. British Health Minister Andrew Lansley asked the Human Fertilization and Embryology Authority (HFEA) to assess three-parent in-vitro fertilization (IVF) after researchers said they had mastered the technique using cloning technology, Reuters is reporting. Newcastle University has refined the technique which swaps DNA between two...

Scientists have analyzed the genomes of humans and closely related primates and discovered over 500 regulatory regions that chimpanzees and mammals have that humans do not.  Gill Bejerano, a biologist at Stanford University School of Medicine, and colleagues found that humans lack the penile spines found in many other mammals, and also why specific regions of human brains are larger than those of our closest relatives. "Rather than looking for species-specific differences in specific...

For the last several years, neurologists have been probing a connection between Parkinson's disease and problems with mitochondria, the miniature power plants of the cell. Toxins that mimic Parkinson's effects act specifically to poison mitochondria, and mitochondria appear to be damaged in the brain cells that are endangered in the disease. But one unresolved question has been: are mitochondria simply the vulnerable "canaries in the coal mine" or is their deterioration a key step on the way...

A curious contagious cancer, found in dogs, wolves and coyotes, can repair its own genetic mutations by adopting genes from its host animal, according to a new study in the journal Science. Scientists at Imperial College London have uncovered an unusual process that helps the cancer survive by stealing tiny DNA-containing 'powerhouses' (known as mitochondria) from the cells of the infected animal, to incorporate as its own. They say this may be because genes in the tumour's own mitochondria...

Medical researchers who crave a means of exploring the genetic culprits behind a host of neuromuscular disorders may have just had their wish granted by a team working at the National Institute of Standards and Technology (NIST), where scientists have performed surgery on single cells to extract and examine their mitochondria. The scientists reached into these cells and extracted their "engines""”the mitochondria that are in large part responsible for our metabolism. Many human cells...

Austrian researchers have uncovered mutations throughout the mitochondrial genome that are associated with prostate cancer. An exciting aspect of the study, published by Cell Press on December 2 in the American Journal of Human Genetics, is the association of tRNA mutations with elevated levels of prostate-specific antigen (PSA) in Austrian men diagnosed with various stages of prostate cancer. Prostate cancer is among the most prevalent cancers diagnosed in the United States and Europe. The...
