Genetic link to autism found, known as CHD8 mutation

In a collaboration involving 13 institutions around the world, researchers have broken new ground in understanding what causes autism. This is the first time researchers have shown a definitive cause of autism to a genetic mutation. Previously identified genetic events like Fragile X, which account for a greater number of autism cases, are associated with other impairments, such as intellectual disability, more than autism. “We finally got a clear cut case of an autism specific gene,” said Raphael Bernier, the lead author, and UW associate professor in the Department of Psychiatry and Behavioral Sciences and the clinical director of the Autism Center at Seattle Children’s.Bernier said people with a mutation in the CHD8 gene have a very “strong likelihood” that they will have autism marked by gastrointestinal disorders, a larger head and wide set eyes.In their study of 6,176 children with autism spectrum disorder, researchers found 15 had a CHD8 mutation and all these cases had similar characteristics in appearance and issues with sleep disturbance and gastrointestinal problems.

Bernier and his team interviewed all 15 cases with CHD8 mutations.

To confirm the findings, researchers worked with scientists at Duke University who do zebra fish modeling. The researchers disrupted the CHD8 gene in the fish and the fish developed large heads and wide set eyes. They then fed the fish fluorescent pellets and found that the fish had problems discarding food waste and were constipated.

Bernier said this is the first time researchers have shown a definitive cause of autism to a genetic mutation. Previously identified genetic events like Fragile X, which account for a greater number of autism cases, are associated with other impairments, such as intellectual disability, more than autism. Although less than half a percent of all kids will have this kind of autism related to the CHD8 mutation, Bernier said there are lots of implications from this study.

Leveraging the showcase provided by the BIO International Convention, the Chilean Association of Biotechnology (ASEMBIO) alongside Grünenthal Chile, CORFO, INAPI, ProChile and CIE Chile organized the Chilean Pavilion, whose aim was to show the attendees potential country as a business platform and the different areas in which trabaja.El event, which takes place every year in the U.S. and brings together the leading exponents in the field worldwide, seeks to strengthen the network and share experiences and progress . ASEMBIO with its Chile Biotech sector brand, introduced the national scene through the forum, “Building a new bio industry, a public-private initiative: The Case of Chile.” To Araneda Patricio, President of ASEMBIO, “the opportunity to make presentations Theme and master increasingly better position allowed the country and our industry. There are many options and potential deal, this work is long and we are taking the first serious steps in the U.S. market. “Meanwhile, the Chilean Pavilion featured a large number of visitors, which endorsed the position that both public institutions and looking to give private domestic biotechnology industry. In the words of Araneda “this BIO has certainly been the occasion when Chilebiotech and Chile as a country has shown more strength, which is reflected in the number of visits and intensive work on stand by all members and authorities involved. “in addition to the above, and as a way to further enhance the work being done locally, Chilean representatives held collaborative meetings with members of the Bay Bio, Bio Mass, University of California, San Diego , San Diego Economic Development Count, among others. They also held a meeting with the ASEBIO (Spanish Association of Biotechnology) in order to establish closer links and collaborative execution of BIOLATAM 2015 in Santiago de Chile, which already is running.

Gene discovered that activates stem cells for organ regeneration in Planarians


The study, entitled “zic-1 Expression in Planarian Neoblasts after Injury Controls Anterior Pole Regeneration,” was reported in PLOS Genetics.

Many species across the animal kingdom have the ability to regenerate, but the mechanisms that connect injuries to stem cell activation and the production of new tissues are not fully understood. Developmental biologists have established that in the early embryo most animals use “tissue organizers” that secrete proteins to allow cell-cell communication for the formation of organs. But it was not clear how such tissue organizers could be produced from scratch to allow adult regeneration in animals like planarians.

Sweet genes: New way found by which metabolism is linked to the regulation of DNA

Scientists have discovered a new way by which metabolism is linked to the regulation of DNA, the basis of our genetic code. The findings may have important implications for the understanding of many common diseases, including cancer.

The DNA wraps around specialized proteins called histones in the cell’s nucleus. Normally, histones keep the DNA tightly packaged, preventing the expression of genes and the replication of DNA, which are required for cell growth and division. In order for these critical functions to take place, histones need to be modified with the attachment of an acetyl-group, donated by a critical molecule called acetyl-CoA. This attachment relaxes the DNA, allowing for DNA replication and gene expression. This mechanism is called “epigenetic regulation of DNA” and is important for normal functions (like the growth of an embryo or brain functions) or in common diseases like heart failure or cancer. Until now, how the nucleus generates acetyl-CoA for histone acetylation had remained elusive.

Aging: Too Much Telomerase Can Be as Bad as Too Little


How do I knock off thirty years from my age?

Faust, the protagonist in Johann Wolfgang von Goethe’s famous play, poses this question to Mephistopheles in the chapter Hexenküche (Witches’ kitchen). Mephistopheles provides some pretty good advice – considering that he is the devil and this fictitious exchange takes place in the dark Middle Ages:

Begib dich gleich hinaus aufs Feld,

Fang an zu hacken und zu graben

Erhalte dich und deinen Sinn

In einem ganz beschränkten Kreise,

Ernähre dich mit ungemischter Speise,
