Technique Accelerates Gene Discovery
2013-12-13 08:05:12

redOrbit Staff & Wire Reports - Your Universe Online Researchers working to decipher the role of genes since the completion of the Human Genome Project may see their efforts accelerated by a new approach that lets them permanently and selectively delete genes from a cell's DNA. The new system, known as CRISPR, was developed by researchers at MIT, the Broad Institute, and the Whitehead Institute, and should allow scientists to study the entire genome at once. In two new papers...

Researchers Show B Cells Can Deliver Potentially Therapeutic Bits Of Modified RNA
2013-11-26 06:59:03

University of California - San Diego Researchers at the University of California, San Diego School of Medicine have successfully targeted T lymphocytes – which play a central role in the body's immune response – with another type of white blood cell engineered to synthesize and deliver bits of non-coding RNA or microRNA (miRNA). The achievement in mice studies, published in this week's online early edition of the Proceedings of the National Academy of Sciences, may be the first step...

Two Y Genes Can Replace Entire Y Chromosome For Assisted Reproduction In Mice
2013-11-21 15:33:20

University of Hawaii at Manoa The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y. "Does this mean that the Y chromosome (or most of it) is no longer needed? Yes, given our current...

As the Do-It-Yourself Biology (DIYbio) community has grown, so have concerns among media and policymakers about these science enthusiasts’ ability to wield DNA and manipulate life. In 2009, for example, a Wall Street Journal headline summed up the popular misconception: “In Attics and Closets, ‘Biohackers’ Discover their Inner Frankenstein.” But in a first-ever survey of DIYbio practitioners (DIYers), the Synthetic Biology Project at the Woodrow Wilson International Center for...

University of Adelaide researchers have taken a step forward in unraveling the causes of a commonly inherited intellectual disability, finding that a genetic mutation leads to a reduction in certain proteins in the brain. ARX is among the top four types of intellectual disability linked to the X-chromosome in males. So far, 115 families, including many large Australian families, have been discovered to carry an ARX (Aristaless related homeobox) mutation that gives rise to intellectual...
