Plant species are threatened by pathogens and pests, and the climate crisis is making things worse. CRISPR could help address some forest health threats, by making trees more resilient. But intervening in a complex ecosystem is a big decision. What are the alternatives? What are the uncertainties? Let’s think about a specific example, the American chestnut, and watch this iBiology video.
Crispy salads are here!

I must say that I’m a bit envious and eager to taste this kind of Brassica juncea with the “mustard bomb” mechanism prevented by knocking-out multiple copies of the gene responsible for the bitter taste.

The Women in Enterprising Science Program (WIES) is located on the UC Berkeley campus and is supported by the foundation of Solina Chau Hoi Shuen (co-founder of Horizons Ventures in Hong Kong). The initiative, aiming to enhance gender equity in bio-entrepreneurship, was presented last March by IGI, the institute founded by Jennifer Doudna. In the pictures above you can see the inaugural cohort of fellows, announced this month.

Cholesterol down – ready set edit!

Last week Verve Therapeutics dosed the first patient with a candidate treatment for hypercholesterolemia. This is exciting news for a couple of reasons. First, the technology used: CRISPR 2.0, i.e., base-editing is hitting the clinic (see the news in Nature Reviews Drug Discovery). Second, this is a leap forward into common diseases (“CRISPR for the masses”, says The Washington Post) and a training session for the real challenge, which is to “stop the biggest killer on Earth”, cardiovascular disease (MIT Technology Review).
Happy 10th Birthday CRISPR!

The seminal paper by Doudna & Charpentier was published online at the end of June 2012. The printed issue came out a few weeks later, on August 17 (don’t try to buy it, Science VOLUME 337|ISSUE 6096 is out of stock). No wonder the gene-editing community is in the mood for celebration these days. If you are too, don’t miss the chance to read these articles on CRISPR’s ten-year anniversary!

Jonathan Weissman and colleagues used a CRISPR-based method to link each expressed human gene to its function in the cell. Here’s our suggested readings to learn more:

A pig virus in the xenoheart. How bad is the news?

As you probably know, the first patient with a pig heart died two months after the transplant surgery. You probably heard also that a porcine cytomegalovirus (PCMV) may have contributed to the death. However, if you are still wondering how bad is the news for the future of xentransplantation, Linda Scobie from Glasgow Caledonian University is the one to listen to. She leads a research group interested in viral zoonoses in the context of novel technologies such as xenotransplantation, and the contribution and/or reactivation of viruses in chronic disease conditions. Professor Scobie is a member of the World Health Organisation committee for the global consultation on regulatory requirements for xenotransplantation trials. I reached her by email for a feature just published in Le Scienze, the Italian edition of Scientific American. Below you can read her answers.

Have you heard of GEN Biotechnology? Issue 3 is already out, but I’ve just got my free copy of the inaugural issue (thanks!). Same publisher (Mary Ann Liebert), same executive editor (Kevin Davies), and the same passion for biotech frontiers as The CRISPR Journal. See below some crispy starters from issue number 1:

The San Raffaele-Telethon Institute in Milan has been a leading player in gene therapy for many years. Nowadays, Angelo Lombardo, Luigi Naldini, and colleagues are making news with epigenetic editing. Their 2016 paper in Cell on hit-and-run epigenetic editing is considered seminal work. The company they co-founded, Chroma Medicine, received substantial financing, as recently reported by Nature Biotechnology. Last but not least, the presentation given in May at the annual meeting of the American Society of Gene and Cell Therapy inspired a Science news entitled “Better than CRISPR? Another way to fix gene problems may be safer and more versatile.” In brief, they injected mice to silence the expression of the PCSK9 gene, lowering “bad” cholesterol levels for months
