Three-Parent Conception Helps Reduce Risk Of Inherited Mitochondrial Disease
2014-06-03 12:53:49

Brett Smith for redOrbit.com - Your Universe Online To prevent deadly, inherited mitochondrial diseases – UK doctors have devised a unique scheme: create a fertilized embryo using eggs from two different women and sperm from one man. According to a new report from the country’s Human Fertilization and Embryology Authority (HFEA), the proposed procedure would be safe and possibly useful, setting the stage for a debate surrounding the ethics of engineering a three-parent child. The US...

New research from the University of California, Davis, shows that the tiny proportion of a cell's DNA that is located outside the cell nucleus has a disproportionately large effect on a cell's metabolism. The work, with the model plant Arabidopsis, may have implications for future treatments for inherited diseases in humans. Plant and animal cells carry most of their genes on chromosomes in the nucleus, separated from the rest of the cell. However, they also contain a small number of genes...

UK Approves Three Person IVF
2013-06-28 12:33:48

Brett Smith for redOrbit.com - Your Universe Online A controversial yet lifesaving treatment that essentially engineers three-parent children using in vitro fertilization (IVF) and third-party mitochondrial DNA will move ahead with clinical trials in the UK, according to British officials. The procedure involves taking dysfunctional mitochondrial DNA from a prospective mother and swapping it out for healthy mitochondrial DNA from a female donor. The technique, called mitochondrial...

Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...

The trade in ivory was largely outlawed in 1989, but poaching continues and remains a serious threat to the African elephant. Seizures of large amounts of ivory, sometimes over a ton, continue to occur. Research by Alfred Roca, an assistant professor at the university, could be the basis for the development of new law enforcement tools. Roca has found a way to determine where the ivory comes from. With funding from the Division of International Conservation of the U.S. Fish and Wildlife...

Mutations in Mitochondria Affect Lifespan Of Men But Not Women
2012-08-03 11:56:45

Connie K. Ho for redOrbit.com — Your Universe Online Higher salaries and acceptance to elite colleges are a few of the benefits that men have over women. However, there is one title that women have long held over men—living longer. Researchers from Monash University in Australia recently discovered some of the facts that contribute to longer life expectancy for women, who, on average, live longer than men. In the project, Dr. Damian Dowling of Monash worked with Florencia...

(Ivanhoe Newswire) --A game-changing find challenges previously held beliefs about the role of mutations in cancer development. Researchers at the Fred Hutchinson Cancer Research Center in Seattle say their findings show that the number of new mutations is significantly lower in cancers than in normal cells. "This is completely opposite of what we see in nuclear DNA, which has an increased overall mutation burden in cancer," cancer geneticist Jason Bielas, Ph.D., an assistant member of the...

In exploring the genetics of mitochondria — the powerhouse of the cell — researchers at Fred Hutchinson Cancer Research Center have stumbled upon a finding that challenges previously held beliefs about the role of mutations in cancer development. For the first time, researchers have found that the number of new mutations are significantly lower in cancers than in normal cells. "This is completely opposite of what we see in nuclear DNA, which has an increased overall mutation...

This family comprises a cluster of six genes that may be altered in neurological conditions, such as Parkinson´s and Charcot-Marie-Tooth disease A team headed by Eduardo Soriano at the Institute for Research in Biomedicine (IRB Barcelona) has published a study in Nature Communications describing a new family of six genes whose function regulates the movement and position of mitochondria in neurons. Many neurological conditions, including Parkinson´s and various types of...

Study also highlights shortcomings of current genetic testing methods to prevent certain genetic disorders Research conducted at the Oregon National Primate Research Center at Oregon Health & Science University helps answer some long-standing questions about how certain disease-causing gene mutations are inherited. The research specifically focused on gene mutations in cell mitochondria that can cause several diseases, including forms of cancer, diabetes, infertility and...
