CRISPR Technology explained by Dr. Martínez Mojica

El impacto de la tecnología CRISPR en biomedicina.

Sesión científica celebrada en la sede de la Reial Acadèmia de Medicina de les Illes Balears el 9 de julio de 2019 a cargo del profesor Francisco Juan Martínez Mojica, microbiólogo, investigador y profesor español titular del Departamento de Fisiología, Genética y Microbiología de la Universidad de Alicante.

Genome editing: a potential weapon of mass destruction

The Patent Dispute Over Gene Editing Technologies: The Broad Institute, Inc. vs. The Regents of the University of California

Nobody could imagine two decades ago that a small part of wide range of bacteria's immune system could represent so much for genome editing. Known as CRISPR, clustered regularly interspaced short palindromic repeats, such mechanism can recognise and defend against viruses. The other part of the defense mechanism is a set of enzymes called Cas that can cut DNA and avoid the invasion of viruses. Mostly, these research was originated in Les Salines d'Alacant by Francisco Mojica a microbiologist.
As far as this is a natural process Dr. Mojica didn't show interest in patenting it. Now the row over patents is hot between UC Berkeley and the Broad Institute. I will skip details, you may find it in The Economist.
It seems that the fight is only to determine who was the first, and the Court will have to decide on March 9th. However, my question is: why is it still possible to file a patent over human nature?.
Meanwhile the public debate may be moved towards the use of such CRISPR technology for genome editing, and Science was publishing an article about the threat that misuse represents for human beings. Are we facing a new weapon of mass destruction?
Both issues, patents and bioethical implications are crucial at the moment. Former examples provide clear guidance of outcomes that should be avoided. Unfortunately, the race for the biggest size of the pie (billions of $) seems to be a priority over health and humanity.

CRISPR Nobel prize

 Genetic scissors: a tool for rewriting the code of life


The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2020 to

Emmanuelle Charpentier, Max Planck Unit for the Science of Pathogens, Berlin, Germany

Jennifer A. Doudna, University of California, Berkeley, USA

“for the development of a method for genome editing”

Popular information: Genetic scissors: a tool for rewriting the code of life (pdf)

Scientific Background: A tool for genome editing (pdf)

Unfortunately, the Royal Swedish Academy of Sciences has shown its ignorance about the real discovery of CRISPR. It happened in the '90s in Salines de Santa Pola by Dr. Martinez Mojica.

Genome editing: the game of biology is about to change

Hacking the Code of Life: How gene editing will rewrite our futures

The foundations of gene editing came about because a scientist in Alacant, Dr. Mojica started to find weird DNA sequences in some bacteria he was studying. After that Profs. Doudna and Charpentier and later Prof. Zhang translated initial findings into practice. Therefore it all started when a microbiologist studied the arms race between bacteria and viruses.
You'll find all these details in a book by Nessa Carey. If you want to understand in plain words what CRISPR is and what may represent for biology, then you have to read it.
The gene editing revolution is creating a technological toolkit that almost any half-decent scientist can lean into and find something useful. On the one hand, that should make us very excited. We can both solve problems and simply indulge our curiosity. But should it also make us worried? Using chisels and a mallet, Michelangelo created some of the most exquisite sculptures we have ever seen. But give the same heavy, sharp tools to someone else, and we can get a very different and much bloodier outcome.
But the same technology can also be used to alleviate human suffering, and if we are smart enough, lessen the impact that our heavy-footed species has on the only planet we know of in the entire universe that supports complex life. We cannot un-invent this technology, we probably can’t even control its spread. So what choice do we really have but to embrace it and use it well, to create a safer, more equal world for all?

The long and bumpy road to CRISPR (2)

 Editing Humanity. The CRISPR Revolution and the New Era of Genome Editing

In 2017 I wrote a post about the book by Jennifer Doudna, A Crack in Creation, now Kevin Davies, the editor of the CRISPR journal has published a new book on CRISPR. It is an effort to put all the information and details about CRISPR in one book. Therefore, if you want to now the whole story (or close to) this is the book to read. If you are interested in a general approach, then the Doudna book is better.

It is quite relevant the chapter that explains the role of Francis Mojica in CRISPR (chapter 3), and the chapter 18, on crossing the germline and what happened about the scandal of genome editing by JK.

“When science moves faster than moral understanding,” Harvard philosopher Michael Sandel wrote in 2004, “men and women struggle to articulate their own unease.” The genomic revolution has induced “a kind of moral vertigo.”49 That unease has been triggered numerous times before and after the genetic engineering revolution—the structure of the double helix, the solution of the genetic code, the recombinant DNA revolution, prenatal genetic diagnosis, embryonic stem cells, and the cloning of Dolly. “Test tube baby” was an epithet in many circles but five million IVF babies are an effective riposte to critics of assisted reproductive technology.

With CRISPR, history is repeating itself,

That's it, great book.
