Man’s second face transplant is a world first
Posted by Genevieve Klien in categories: biotech/medical, genetics, neuroscience
A man in Paris has become the world’s first to successfully receive two facial transplants.
Jérôme Hamon, 43, underwent his first face transplantation procedure in 2010 to treat neurofibromatosis, a genetic disorder characterized by the growth of tumors along nerves in the skin, brain and other parts of the body. Yet Hamon’s body rejected the original transplant.
In January, a team of surgeons and paramedics at Georges Pompidou European Hospital AP-HP, led by surgeon Dr. Laurent Lantieri, performed Hamon’s second transplant.

CRISPR plants won’t be regulated
Posted by Shailesh Prasad in categories: bioengineering, biotech/medical, genetics
In a big win for the biotech industry, the US Department of Agriculture says once and for all it won’t regulate plants whose genomes have been altered using gene-editing technology.
Why it’s a field day: The decision means that we could see a boom in newfangled plants from firms like Monsanto, universities, and startups like Calyxt, whose oil-altered soybeans featured in our cover story late last year.
Here’s the logic: The USDA says gene editing is just a (much) faster form of breeding. So long as a genetic alteration could have been bred into a plant, it won’t be regulated. That includes changes that create immunity to disease or natural resistance to crop chemicals, as well as edits to make seeds bigger and heavier. It doesn’t include transgenic plants (those with a gene from a distant species)—those will still be regulated.

Breakthrough brings gene-editing medicine one step closer to patient applications
Posted by Ian Hale in categories: bioengineering, biotech/medical, genetics
Imagine a future where a guided biomachine put into your body seeks out defective gene sequences in each cell and edits in the correct information with precision accuracy.
It’s called gene editing, and University of Alberta researchers have just published a game-changing study that promises to bring the technology much closer to therapeutic reality.
“We’ve discovered a way to greatly improve the accuracy of gene-editing technology by replacing the natural guide molecule it uses with a synthetic one called a bridged nucleic acid, or BNA,” said Basil Hubbard, Canada Research Chair in Molecular Therapeutics and an assistant professor in the U of A’s Department of Pharmacology, who led the study.

Scientists Edit Thousands of Genes at Once With Upgraded CRISPR
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, genetics
When the gene-editing technology CRISPR first made a splash back in 2012, it foretold a future in which curing diseases might simply involve snipping out problematic bits of genetic code. Of course, innovation is rarely so straightforward. As incredible as CRISPR is, it also has some pretty sizable flaws to overcome before it can live up to its hype as a veritable cure-all for human disease.
A new study published this week in the journal Nature Genetics tackles one CRISPR complication. CRISPR gene-editing systems can easily cut many pieces of DNA at once, but actually editing all those genes is a lot more time-consuming. Now, scientists at UCLA have come up with a way to edit multiple genes at once.
When scientists use CRISPR for genetic engineering, they are really using a system made up of several parts. CRISPR is a tool taken from bacterial immune systems. When a virus invades, the bacterial immune system sends an enzyme like Cas9 to the virus and chops it up. The bacteria then adds short bits of virus DNA to its own code, so it can recognize that virus quickly in the future. If the virus shows up again, a guide RNA will lead the Cas9 enzyme to the matching place in the virus code, where it again chops it up. In CRISPR, when that cutting is done, scientists can also insert a new bit of code or delete code, to, for example, fix disease-causing genetic mutations in the code before patching it up. But delivering that new code and making the patch is where it can get especially tricky.
