The CRISPR biomedical duel between China and the US has been called “Sputnik 2.0”. Is Europe being left behind?

JD: As with any disruptive technology, there is intense competition to lead. However, unlike the space race, the CRISPR research effort is global and more collaborative. We consistently see key advances in CRISPR technology shared through scientific papers, written and read by research teams around the world. This collective approach has helped to democratize the technology. However, differing regulations across countries may impact how we ultimately translate research into real-world applications that can benefit the most number of people with the most need. Researchers in Europe have made valuable contributions to the development and application of CRISPR and will continue to play a role in establishing global standards. Continue reading

China vs USA: who leads the CRISPR race?

China vs US

The first human CRISPR trial approved in the United States is finally recruiting the first patient. In the meantime trials have grown to a dozen in China, considering those revealed by the Wall Street Journal inquiry besides the NIH database (check also this npr article for further details). Over 80 Chinese patients are already receiving a CRISPR-based treatment, while US researchers cautiously plan to test the safety of their experimental therapy on a single subject, and, if everything goes right, two more patients will be treated a month later. Is the West losing its genome-editing edge to Beijing? Continue reading

Playing a three of CRISPR kind

three acesIt is Science but it could be mistaken for The CRISPR Journal. The latest issue indeed runs three papers by three CRISPR aces – David Liu, Jennifer Doudna, and Feng Zhang – about the cutting-edge fields of biological recorders and advanced diagnostic tests. Continue reading

CRISPR latest edition

crispr-latest-edition[8047]There is hardly any day without CRISPR news. February starts with researchers correcting abnormalities associated with Duchenne muscular dystrophy (Science Advances) and performing allele-specific editing in blind mice (bioRxiv, forthcoming in The CRISPR Journal). A repechage from January also: how to get pluripotent stem cells by CRISPRing just one gene (Cell Stem Cell).

Epigenetic editing hits hat-trick

editing epigenetico Cell

Reversing three genetic diseases in the animal model without even changing a single DNA letter. A Salk Institute team did it by bringing together two of biomedicine’s hottest trends. One is the CRISPR technique, which edits target genes through a programmable molecular machine named Cas9. The other is epigenetics, i.e., the study of chemical modifications that switch genes on and off without altering their sequence. It’s called epigenetic editing, because corrections are precise as in manuscript revision and occur at a level that is over (epi- in Greek) genetics. Continue reading

Gene drives: the experiment goes social

harvard-mag-pete-ryanChoose a word to fill the gap in the sentence. “Gene drives are an ambitious experiment in …”. Genetics? Ecology? Evolution? Obviously, gene drives are all this and more. They may also represent a significant social experiment in risk communication, public engagement, participatory processes. Potential applications of this technology include controlling the transmission of vector-borne diseases and eliminating invasive species from sensitive ecosystems. We do not yet know if these genetic elements, designed to foster the preferential inheritance of a gene of interest with CRISPR’s help, will work in field trials as hoped. To find out, a green light to test this technology out of the labs will have to be negotiated with the public, stakeholders, regulators, and governments of affected countries. A first step in this direction was taken last week with the commitment to respect shared guiding principles in gene drive research and communication published in Science by the technology main sponsors and supporters. Signatory organizations are scattered around the world, from the US to India, with the Bill & Melinda Gates Foundation at the forefront with its Target Malaria project. Continue reading
