Redditemailprintcalifornia lecture, at berkeley, biochemist jennifer doudna received today 2020 nobel prize in chemistry, shared with colleague emmanuelle charpentier to co-develop crispr-cas9, a breakthrough in genome editing that has revolutionized biomedicine.

 

 

Crispr-cas9 allows scientists to rewrite dna — the code of existence - in any organism, including human cells, with unprecedented operational clarity and accuracy. The revolutionary power and versatility of crispr-cas9 has opened up new and indispensable preferences in biology, farming and medicine, including the treatment of thousands of intractable diseases. Max planck will share the prize of 10 million sek (over one million us dollars).

 

 

"This great honor recognizes the history of crispr and the shared history of its use in the most powerful engineering technology, which gives new hope and opportunities to our society," dudna said. "What started as a blueprint for fundamental discoveries, written on curiosity, has now become a breakthrough strategy used by countless researchers working to improve the ways of human existence. I call for continued support for basic science as well as public discussion about the ethical exploitation and responsible regulation of crispr technology."

While women were conducting research at uc berkeley that earned them the nobel prize after they left campus, doudna became the first woman on the faculty university of california at berkeley. Take the coveted reward. She is the 25th nobel laureate on campus; the 24th laureate, reinhard genzel, received the nobel prize in physics just yesterday.

 

 

Today's honor also brings another innovation: dudna and charpentier are the first ladies who jointly received the nobel prize in natural sciences that, according to dudna, now that "women are tough."

 

 

"Quite often, women believe that no matter what they form, their goal under no circumstances will remain recognized as such how it would be if the devices were a man, "said dudna, who was awakened by a reporter today at 2:53 in the morning after learning that the porn bunny had won the nobel prize for the first time. "And i think that such an award) refutes this. This is a strong statement of knowledge that ladies can immerse themselves in science, women can do chemistry, and what great science is recognized and honored. That if i was growing up, i couldn't have imagined this question in a million years."

Dudna said the porn bunny is "very, very proud to represent berkeley, ... A public university that supports great science and great education, ... A place which welcomes everyone, people from all over the world". She added: "it's a great feeling to have such great colleagues who are involved in the current one."

 

 

Dudna and charpentier were honored by the nobel foundation for their discovery of the gene-cutting cas9 molecule. , Used by bacteria to kill viruses, is transformed into an accurate and simple gene-editing tool at its best. The crispr-cas9 system is controlled by an rna molecule to bind to a particular sphere of dna, and at the end, the cas9 protein acts as a pair of molecular scissors, cutting the dna, allowing it to be altered in a meticulous manner. This work "opened a revolutionary new era in genomics," said university of california president michael w. Drake, md, in a description dedicated to doudna.

Conducting basic scientific research

 

Dudna's research focuses on rna, dna's partner in transferring genetic material and a key part of several molecular machines (like the ribosome and telomerase) that help dna do its job. She became interested in crispr because of a personal longstanding interest in such machines containing rna.

 

 

Dudna's attention to crispr was first attracted by a colleague from the university of california at berkeley, jill banfield, https://keycodesoftware.com/ who encountered a smoker while studying bacteria living in extreme conditions. The system intrigued dudna, who wondered how exactly the unusual repetitive dna sequence in the bacterial genome allows bacteria to successfully defend themselves against viral infections. They and other scientists have found that if viruses invade bacteria, the bacteria will cut the viral dna and place those segments in their genome like the most wanted posters." If similar viruses invade again, wandering enzymes with rna copies of these viral dna fragments examine the virus, and if the rna and dna match, they cut the dna and kill the virus.

 

 

Charpentier focused on this. About the type 2 system (crispr-cas9) even above, published in nature in 2011, described an unusual rna not found in other crispr systems - tracrrna (pronounced "tracer rna") - and how it works in conjunction with cas9. Protein to allow copies of the "most wanted posters" rna to be obtained. Later, she and doudna looked at the problem of how the cas9 protein might also be involved in crispr's final step in immunity: spying on the cell and cutting invading dna. They began their collaboration the same year after meeting at a scientific conference in puerto rico. Guided as tracrrna, never by the rna corresponding to the viral sequence, then it uses to search for and destroy matching viral dna.

 

 

Perhaps more valuable, the two scientists also found that such a cellular defense system had applications apart from destroying viruses. They converted the two-part rna into a single rna and showed that it could be constructed to accurately label any gene from different species, not just bacteria, by allowing the cas9 protein to cleave here. Doudna and charpentier then made the far-sighted proposal that crispr-cas9 might be repurposed into an extremely powerful tool for editing plant or animal genomes, including human genes, and tuned to remove or add specific strands of dna.

 

 

"Jennifer throughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughoutthroughout duringduringduring has been a pioneer in the field of structural biology for many years in accepting the three-dimensional system and the operability of rna," said robert tian, professor of molecular and cellular biology at the university of california at berkeley and former head of the medical institute howard hughes. "Her development of the single-conductor fusion rna was essential to realizing the viable and empirical use of crispr-cas9 as a high performance molecular gene editing tool. Her continued work on the a priori structures of the cas9/guide rna complex was critical to the subsequent improvement of this powerful technology."

 

 

In early 2013, the uc berkeley dudna lab and others demonstrated a system that could edit human dna. In the eight years since dudna and charpentier published their landmark 2012 paper, crispr-cas technology has been used in almost every field of biomedicine, recklessly proving the power of their colleagues' vision.

 

 

In 2008 doudna's nascent research into crispr rna strands and the cas1 protein was funded by the us department of energy's (doe) research and development program through its affiliate at berkeley lab.Established by congress in 1991, the ldrd program has helped keep the united states at the forefront of technology through advanced interdisciplinary research from the us department of energy's national laboratories. Has become commonplace in labs all over the world because it is amazingly easy to use. Despite the "low barrier to entry", it is reliable in a rich range of settings. In particular, it contains new ways to treat and cure diseases, grow the latest generation of crops for a rapidly warming world, and understand the functions of living structures with astonishing speed and clarity.

 

 

In medicine, scientists and doctors have used crispr enzymes -cas to clearly change the genetic code of human cells and organs in a way that promises something in the treatment of genetic disorders and various disorders. It is remarkable that in just eight years this technology has gone from being so promising in theory to being the basis of numerous experimental efforts to treat genetics, viruses and cancer.

 

 

Thousands of laboratories around the world are already using crispr to create laboratory animals with genetics that mimic a human disease so that we can learn how a genetic defect causes symptoms and test ways to fix the problem.

 

 

In agriculture, researchers around the world are using crispr-cas9 to enhance crops that are resistant to pests and diseases, as well as healthier, more nutritious crop varieties. Highlighting the versatility of crispr-cas technology, this method is being used as a so-called "gene drive" material to monitor mosquito populations and suppress their ability to spread zika virus and malaria.

 

 

Three years ago, doudna was one from the organizers of the first international symposium at his native academy of sciences, dedicated to the social and ethical use of crispr technology. She has been at the forefront of the debate and advocated for an inclusive global discussion before making genetic changes to human sperm, eggs and embryos. She continues to encourage the medical and scientific community, as well as the general public, to discuss whether changes in the human germline are acceptable, and if so, when.

 

 

Dudna and charpentier have many awards for their invention, sharing award in 2014. Achievement award in genetics, gruber prize in genetics 2015, princess of asturias prize for instrumentation and science 2015, unesco l'oreal prize for girls in science 2016, canada gairdner international prize 2016, prize japan 2017 and the kavli prize 2018 nanoscience prize.

 

 

Dudna has also received a huge number of other major awards, even the lurie prize in biomedical sciences, the dr. Paul janssen prize for biomedical research, the dr. H. P. Heineken prize for biochemistry and biophysics; and the lui che woo prize for welfare improvement. She is a member of the national academy of sciences, the american academy of arts and sciences, the institute of medicine and the national academy of inventors, and a foreign member of the royal society. Three years ago, she was named by foreign policy magazine as one of the 100 proven international thinkers, and another one of the 100 most influential fans according to time.

 

 

Dudna was born in washington, dc, and grew up in hilo, hawaii, and got into chemistry during high school. She graduated from pomona college in claremont, california in 1985 with a degree in biochemistry, then went on to graduate school at harvard university. She received her ph.D.
