University of Oregon-made technique is putting new light on machinery driving intracellular transport Using new technology developed in his University of Oregon lab, chemist Andrew H. Marcus and his doctoral student Eric N. Senning have captured what they describe as well-orchestrated, actin-driven, mitochondrial movement within a single cell. That movement -- documented in a paper appearing online the week of Dec. 14-18 ahead of regular publication in the Proceedings of the National Academy...

OMAHA, Neb., Dec. 17 /PRNewswire-FirstCall/ -- Transgenomic, Inc. (OTC Bulletin Board: TBIO) announced today that it has reached agreement with Gene Solutions for an exclusive licensing option to a set of validated mutations found in Parkinson's disease patients that can form the basis of a novel and accurate diagnostic test for Parkinson's disease. Transgenomic's platform mitochondrial mutation detection technology will be evaluated and optimized to develop a diagnostic test that...

Soon you could be genetically screened for mitochondrial disorders quickly and comprehensively. Research published in BioMed Central's open access journal, Genome Medicine, outlines an innovative clinical diagnostic test for the early identification of a wide range of mitochondrial disorders. Mutations to one of the mitochondrial genes, or to a number of nuclear genes with roles in mitochondrial function, can cause diseases which have very similar symptoms, making them difficult to diagnose...

Diet boosts mitochondrial function, has implications for humans Flies fed an "anti-Atkins" low protein diet live longer because their mitochondria function better. The research, done at the Buck Institute for Age Research, shows that the molecular mechanisms responsible for the lifespan extension in the flies have important implications for human aging and diseases such as obesity, diabetes and cancer. The findings, which appear in the October 2 edition of Cell, also provide a new level of...

Researchers are delving into abnormal gene function in mitochondria, structures within cells that power our lives. Mitochondria are the place where energy is generated from the most basic molecules of food. Because this function is essential to life, defects in mitochondria may affect a wide range of organ systems in humans and animals. Some names of mitochondrial disorders are Leigh's disease, MELAS syndrome and complex I deficiency. These are often severe and progressive conditions that...

WOBURN, Mass., Aug. 27 /PRNewswire/ -- U.S. researchers using CRi's Oosight(TM) imaging system have developed a gene transfer technique that has potential to prevent inherited diseases passed on from mothers to their children through mutated DNA in cell mitochondria. The research, which demonstrated the technique in rhesus monkeys, appears in the Aug. 26 issue of the journal Nature. The group, headed by Dr. Shoukhrat Mitalipov of the Oregon National Primate Research Center and the Oregon...

Researchers believe they have found a way to avoid certain genetically inherited disorders through a special kind of in vitro fertilization (IVF).  Ethical concerns abound, but experts say that the future of the procedure looks promising. In lab experiments with rhesus macaque monkeys, scientists from the Oregon Health and Science University were recently able to transfer DNA from the nucleus of an unhealthy egg cell into a normal egg cell without a nucleus, ultimately resulting in the...

The normal aging process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesized in the cellular mitochondria "“ popularly known as the cells' power plants "“ become unstable and disintegrate, which in turn can impair cell respiration and cause premature aging.Every time we inhale, the blood...

Gene mutations that once helped humans evolve and survive could increase the risk of cancer and other diseases today, researchers in Israel said. The mutations were found in the genome of the mitochondria, the part of cells responsible for energy production that is passed from mother to child, scientists at Ben-Gurion University of the Negev said. Although mitochondria's role in the emergence of new species has been investigated recently, the idea that they are responsible for our...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
