Mount Sinai Researchers Identify Genetic Alterations in Shared Biological Pathways as Major Risk Factor for Autism …

Posted: Published on April 25th, 2014

Contact Information Available for logged-in reporters only Newswise (NEW YORK April 24) A substantial proportion of risk for developing autism spectrum disorders (ASD), resides in genes that are part of specific, interconnected biological pathways, according to researchers from the Icahn School of Medicine at Mount Sinai, who conducted a broad study of almost 2,500 families in the United States and throughout the world. The study, titled Convergence of Genes and Cellular Pathways Dysregulated in Autism Spectrum Disorders, was first published online in The American Journal of Human Genetics on April 24. ASD affects about one percent of the population in the United States and is characterized by impairments in social interaction and communication, as well as by repetitive and restricted behaviors. ASD ranges from mild to severe levels of impairment, with cognitive function among individuals from above average to intellectual disability. Previously, ASD has been shown to be highly inheritable, and genomic studies have revealed that that there are various sources of risk for ASD, including large abnormalities in whole chromosomes, deletions or duplications in sections of DNA called copy number variants (CNVs), and even changes of single nucleotides (SNVs) within a gene; genes contain instructions to produce proteins that … Continue reading

International collaboration unravels novel mechanism for neurological disorder

Posted: Published on April 25th, 2014

PUBLIC RELEASE DATE: 24-Apr-2014 Contact: Glenna Picton picton@bcm.edu 713-798-4710 Baylor College of Medicine HOUSTON (April 24, 2014) A team of international scientists led by Baylor College of Medicine has discovered a novel gene (CLP1) associated with a neurological disorder affecting both the peripheral and central nervous systems. Together with scientists in Vienna they show that disturbance of a very basic biological process, tRNA biogenesis, can result in cell death of neural progenitor cells. This leads to abnormal brain development and a small head circumference as well as dysfunction of peripheral nerves. The study published today in the current issue of the journal Cell. "This is the first human disorder associated with the gene CLP1," said Dr. Ender Karaca, post-doctoral associate in the department of molecular and human genetics at Baylor. The gene find is significant because CLP1 has a role in RNA processing and has important implications for genomic approaches to Mendelian disease and for our understanding of human biology and brain development, Karaca said. Karaca's work with families of this rare disorder began many years ago during his residency training as a clinical geneticist in Turkey. A chance meeting with Dr. James R. Lupski, the Cullen Professor and Vice … Continue reading

Station genetics manager sad to leave

Posted: Published on April 25th, 2014

After seven years, Mt Linton Station genetics manager Hamish Bielski is walking off the farm feeling he has achieved his goal of breeding low-input, high-output sheep. Mr Bielski and his wife Amy have moved to an equity partnership on a 300ha property near Clydevale, in South Otago. He said he was sad to say goodbye to the place, especially when it was starting to see the rewards of an extensive breeding programme involving Texels and Romneys. ''The most successful part of my job was the start of the new maternal breeding programme, which basically held together our top Texels. We also bought Romneys and were heading to stabilise that over the last seven years, coupled with buying 750 of the Tan Bar Romney ewes in 2012. ''In my last two years at the station, I feel as though we are just starting to gain traction and starting to get there. It's taken six years to build the foundation. ''It's almost a bit of a shame to go at a time when we are in a sense starting to see rewards coming through, but it's well set up to keep the progress going.'' Working at Mt Linton station was the best … Continue reading

PUBLIC RELEASE DATE: 24-Apr-2014 Contact: Tamlyn Oliver toliver@clinicalomics.com 914-740-2199 Mary Ann Liebert, Inc./Genetic Engineering News New Rochelle, NY, April 24, 2014GEN Publishing recently introduced Clinical OMICs a semi-monthly digital publication focusing on the application of OMICs technologies in clinical settings. These advanced techniques, such as next-gen sequencing, are beginning to transform medical care just as they revolutionized basic life science research over the past decade-and-a-half. "GEN's editors and reporters have written about the research use of pharmacogenomics, genomics, metabolomics, transcriptomics, etc. etc. for years," said John Sterling, editor-in-chief of Genetic Engineering & Biotechnology News (GEN). "The rapid advance of OMICs technologies has reached the point where we are convinced that the time is now for a new publication that shows how these diagnostic methodologies are dramatically impacting clinical practice." Clinical OMICs is directed at clinical lab directors and managers, oncologists, infectious disease specialists, and cardiologists. Intended to serve as a resource for the development and standardization of best OMICs practices, Clinical OMICs provides critical information and insights on the trend toward personalized medicine. The premier issue contains articles on translating OMICs into cancer biology and medicine, how payers are grappling with reimbursement issues, a profile of Lawrence Brody, who is … Continue reading

Scientists Build a Custom Chromosome

Posted: Published on April 25th, 2014

BALTIMORE, MD. Scientists have built a custom chromosome -- a package of genetic material assembled entirely from synthetic DNA. This engineered chromosome belongs to yeast, but experts say it can help them understand how genes work in humans as well. And it could help make these tiny living factories better at producing everything from medicines to biofuels. Students were key to the project In a lab at Johns Hopkins University, students stitched together machine-made strands of DNA, the chemical that carries the genetic blueprints of life. Their goal: to assemble all 6,000 genes in the genome of yeast. "So, in every single well there should have hopefully been something, said Macintosh Cornwell, a student at Johns Hopkins. Cornwell, a junior, is looking for signs his last stitching reaction worked. So, overall, we had pretty moderate success across the board, he said. Johns Hopkins geneticist Jef Boeke leads the class. He said yeast does familiar jobs, like turning grapes into wine, but they also do more than that. We have yeast that are used not just to make alcohol and bread, but also all kinds of chemicals, medicines, vaccines and fuels. And I think were going to see more and more … Continue reading

Engineered E. coli produces high levels of D-ribose as described in Industrial Biotechnology journal

PUBLIC RELEASE DATE: 24-Apr-2014 Contact: Vicki Cohn vcohn@liebertpub.com 914-740-2100 x2156 Mary Ann Liebert, Inc./Genetic Engineering News New Rochelle, NY, April 24, 2014D-ribose is a commercially important sugar used as a sweetener, a nutritional supplement, and as a starting compound for synthesizing riboflavin and several antiviral drugs. Genetic engineering of Escherichia coli to increase the bacteria's ability to produce D-ribose is a critical step toward achieving more efficient industrial-scale production of this valuable chemical, as described in an article in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Industrial Biotechnology website. In "Engineering Escherichia coli for D-Ribose Production from Glucose-Xylose Mixtures." Pratish Gawand and Radhakrishnan Mahadevan, University of Toronto, Canada, describe the metabolic engineering strategy they used to increase the yield of D-ribose from the genetically modified E. coli, which were able to produce D-ribose from mixtures of glucose and xylose. The authors propose future research directions for additional metabolic engineering and bioprocess optimization. "The research article by Gawand and Mahadevan represents one of many ways that molecular biology is being deployed to expand Industrial Biotechnology development," says Co-Editor-in-Chief Larry Walker, PhD, Professor, Biological & Environmental Engineering, Cornell University, Ithaca, NY. ### … Continue reading
