Covid19 is affecting everyone, but it has hit the sickle cell (SCD) community particularly hard. According to STAT News the pandemic has temporarily stopped clinical trials and the introduction of new drugs, besides directly impacting SCD patients who are at high risk for severe complications from Sars-Cov2 infection and may need hospital assistance for SCD pain crises.Continue reading
Consider this scenario, depicted in Nature a few years ago. “It’s 2037, and a middle-aged person can walk into a health centre to get a vaccination against cardiovascular disease. The injection targets cells in the liver, tweaking a gene that is involved in regulating cholesterol in the blood. The simple procedure trims cholesterol levels and dramatically reduces the person’s risk of a heart attack”.Continue reading
CRISPeR Frenzy asked Luigi Naldini of the San Raffaele Telethon Institute for Gene Therapy in Milan for comment on three studies published in June on the preprint server bioRxiv. The experiments were carried out independently by the groups of Kathy Niakan of the Francis Crick Institute in London, Dieter Egli of Columbia University in New York City, and Shoukhrat Mitalipov of Oregon Health & Science University in Portland. These findings heighten safety concerns about heritable genome editing (see the news item by Heidi Ledford in Nature). Below you can read Naldini’s thoughts.Continue reading
Victoria Gray is the first US patient treated with CRISPR for a genetic disorder. Don’t miss the interview she gave to NPR almost one year after the experimental treatment.
Say hello to CARMEN: a massively multiplexed, Cas13-based technology for nucleic acid detection, out yesterday in Nature. Its name stands for Combinatorial Arrayed Reactions for Multiplexed Evaluation of Nucleic acids, and it allows us to test many amplified samples for the presence of many viral sequences by using miniaturized detection reactions that self-organize in a microwell array. Sars-Cov2 included.Continue reading
Hopefully, CRISPR-based diagnostics will make an early debut amid COVID-19 outbreak. But what about a CRISPR prophylactic strategy to combat coronaviruses? The proof of concept is here, in bioRxiv, but it will be deployed in the next pandemic if we are lucky. It’s called PAC-MAN, like the videogame, stands for Prophylactic Antiviral CRISPR in huMAN cells, and comes from the Stanley Qi Lab.Continue reading
CAR-T cell therapy meets CRISPR. See the results from the first US trial of gene editing in patients with advanced cancer, just published by Carl June and colleagues in Science, together with a perspective by Jennifer Hamilton and Jennifer Doudna and a piece of news by Jennifer Couzin-Frankel. We still don’t know if edited T cells are effective against cancer, but this Phase 1 clinical trial suggests the approach is safe and feasible.
RNA editing takes off. Take a look at the news feature by Sara Reardon in Nature. It’s a four pages introduction to ADAR, an alternative to CRISPR for flexible, reversible therapies.
The new coronavirus spreading in China is one more reason to hear from the multi-talented geneticist how we could make our life virus-proof with DNA recoding and other exciting stuff coming from the Church Lab.
