A multi-disciplinary panel of 18 experts from all over the world, a two years long consultation, over 150 pages. The much-awaited report of the World Health Organization on human genome editing was delivered on July 12 and is divided into three parts: A framework for governance, Recommendations, and Position Paper. While not legally binding, it is expected to influence both governments and the scientific community, by offering a roadmap based on widely shared ethical principles and usable policy tools.

Here you can read a selection of notable comments about the landmark paper on in vivo genome-editing published in the New England Journal of Medicine on 26 June. The trial, conducted in the UK and New Zealand, produced the first-ever clinical data supporting the safety and efficacy of intravenous infusion of a single-dose CRISPR treatment. The treatment, developed by two US-based companies (Intellia Therapeutics and Regeneron Pharmaceuticals) targets a rare and fatal condition called transthyretin amyloidosis.
Jennifer Doudna (CRISPR co-inventor and co-founder of Intellia): “It’s a critical first step in being able to inactivate, repair, or replace any gene that causes disease, anywhere in the body” (source Science).

Anti-CRISPR proteins are the rock needed to stop CRISPR-based mosquito-eradicating gene drives, if necessary, and make them safer. In a news feature published last year in Nature, the molecular parasitologist Andrea Crisanti disclosed unpublished data about halting an anti-malaria gene-drive system by adding anti-drive mosquitoes to the mix. “They can completely, 100% block the drive. We can stop the [Anopheles gambiae] population from crashing,” he said. According to the scientist from the Imperial College London, it’s kind of like buying an insurance. Looking ahead to field-testing his sterilization strategy, Crisanti imagined having cages of anti-drive mosquitoes at the ready, just in case things go awry. Well, that work is now published, and anti-drive mosquitoes are a reality. To learn more, see the paper published on June 25 in Nature Communications by Chrysanthi Taxiarchi et al.
Soon after co-discovering the double helix, Francis Crick coined the term “central dogma of biology” to illustrate the flow of genetic information within biological systems. The basic idea is simple: DNA is the king of the cell, proteins are its major workforce, and RNA is a sort of a middle manager. He later admitted that dogma was a poor word choice for a rule that has exceptions. Indeed, he became one of the proponents of the RNA world hypothesis, where RNA is the primordial substance in the evolutionary history of life on Earth. We can only guess what the great British scientist might say about RNA taking the stage today.

You may have heard of the recent European Commission report on the New Genomics Techniques. But you probably don’t know how member states answered the related questionnaire. ““Could NGT-related research bring opportunities/benefits to science, to society and to the agri-food, medicinal or industrial sector?”. This and more in my news feature for Nature Italy.
“Virologists have infected millions of miniature organs with SARS-CoV-2, to learn how the virus wreaks havoc and how to stop it,” writes Smriti Mallapaty in the latest issue of Nature. In one study, published in Science Immunology in 2020, researchers used CRISPR in gut organoids to identify two proteins (TMPRSS2 and TMPRSS4) that facilitate the virus entry into human cells, together with the ACE2 receptor. “Other labs are knocking out ACE2 entirely, to see whether the virus can still get in”. Here the full text of the news feature.
I’m not sure this video is an effective communication strategy, maybe because I’m Italian (and I have no high blood pressure problems). Anyway, edited seedlings freely distributed to over 5000 home gardeners in Japan is great news!
