UC Berkeley CRISPR scientist wins Nobel

Jennifer Doudna shares chemistry award with French colleague

UC Berkeley’s Jennifer A. Doudna and French scientist Emmanuelle Charpentie­r have won the Nobel Prize in chemistry for making one of the most monumental discoverie­s in biology: a cheap, fast, precise and powerful tool to “edit” DNA, known as CRISPR.

The gene- editing tool gives scientists near godlike power, allowing them to rewrite the code of life by moving genes from one living creature to another. Easily deployable, in merely eight years it has transforme­d research in plant and animal breeding, treatment for hereditary disease and new strategies for combating infectious disease and cancer. Most recently, it was enlisted to create a super-fast test to detect COVID-19 infection.

Doudna, who is the chair in biomedical and health sciences and a Howard Hughes Medical Institute investigat­or at UC Berkeley, has become a leader in the responsibl­e use of the tool, seeking to fend off a dystopian future in which scientists create an elite population of designer babies with enhanced intelligen­ce, beauty or other traits.

Doudna and Charpentie­r are the first all-woman team to win science’s highest honor.

“Many women think that, no matter what they do, their work will never be recognized the way it would be if they were a man,” said Doudna. “And I think (this prize) refutes that. It makes a strong statement that women can

do science, women can do chemistry, and that great science is recognized and honored.”

In a Wednesday morning news briefing, Doudna credited the San Francisco Bay Area with encouragin­g her to “dream big and swing for the fences,” adding that her research thrived through collaborat­ion “with other great universiti­es, and also the extraordin­ary culture that exists in Silicon Valley.”

It offers sweet justice during a contentiou­s and long-running patent battle over the use of CRISPR. Last month, the nation’s Patent Trial and Appeal Board ruled against UC Berkeley, saying that a group led by the Broad Institute of MIT and Harvard has “priority” in its already granted patents for uses of the original CRISPR system in human and animal cells — a finding that, when applied to medicine, could be worth millions of dollars.

The Nobel Prize rewards the fundamenta­l intellectu­al discovery made by Doudna and Charpentie­r. In contrast, the Broad Institute’s research focuses on its applicatio­n in humans.

The recipients were announced Wednesday in Stockholm by Goran Hansson, secretary general of the Royal Swedish Academy of Sciences.

Doudna said she went to bed on Tuesday night with her phone on silent mode, with no thought of the potential prize.

When the call came from Sweden, “I was deeply asleep,” she said. Finally, she was awakened at 2:53 a.m. by the phone’s persistent buzzing. A reporter on the line asked if she could comment on the Nobel.

“Who won it?” Doudna asked. Startled by the news, she reached out to colleagues, “and I was very glad to know it wasn’t all a big joke.”

It was UC Berkeley’s second Nobel Prize in as many days, after the committee honored professor emeritus Reinhard Genzel and UCLA physics and astronomy professor Andrea Ghez for their breakthrou­ghs in understand­ing the mysteries of cosmic black holes.

“This great honor recognizes the history of CRISPR and the collaborat­ive story of harnessing it into a profoundly powerful engineerin­g technology that gives new hope and possibilit­y to our society,” Doudna said Wednesday. “What started as a curiosity- driven, fundamenta­l discovery project has now become the breakthrou­gh strategy used by countless researcher­s working to help improve the human condition.”

The Doudna- Charpentie­r team didn’t conceive of the discovery out of thin air; rather, they discovered it in nature.

On campus in 2005, Doudna was intrigued by a thoughtful conversati­on with environmen­tal researcher Jillian Banfield, who described an obscure trait of microbes: unusual repeating sequences of DNA called “clustered regularly interspace­d short palindromi­c repeats,” or CRISPR. It served as the microbes’ immune system, helping them recognize and kill viruses, Banfield told her.

At a scientific conference in Puerto Rico six years later, she met Charpentie­r, a French microbiolo­gist then at Umea University in Sweden, who was already making important discoverie­s about microbes’ use of CRISPR.

Walking the streets of old San Juan, a partnershi­p was formed. In a eureka moment, the two scientists realized that microbes’ defense system could be enlisted to edit genomes, not just kill viruses.

They demonstrat­ed a way to use CRISPR to slice up any DNA sequence they choose — then add or subtract pieces.

CRISPR- Cas9 isn’t the first gene- editing method. But it is much faster, cheaper, easier and more accurate than earlier versions.

“It’s like the Model T — not the first car but the one that changed the world,” Hank Greely, director of the Center for Law and the Bioscience­s at Stanford Law School, told this news organizati­on in an article about pioneering research in the Bay Area.

Doudna’s discovery in 2012 galvanized the medical community — and now, CRISPR is moving toward testing in humans, with clinical trials for diseases such as sickle cell anemia, blindness, muscular dystrophy, cystic fibrosis and neurodegen­eration.

Concerned about CRISPR’s social implicatio­ns, in 2015, Doudna convened a meeting in Napa that addressed, for the first time, its potential impact. This led to an influentia­l paper in the journal Science, followed by a statement calling for caution and public input by the National Academy of Sciences.

“She sincerely cares about the ethical issues,” said Stanford’s Greely. Even while running a world-class lab, “She has continued to be very active on the regulation and control of CRISPR’s use in humans.”

Since their discovery, Doudna and Charpentie­r have formed competing startup companies. Doudna co-founded Caribou Bioscience­s Inc., Intellia Therapeuti­cs Inc. and Mammoth Bioscience­s. Charpentie­r, who now directs the Max Planck Institute for Infection Biology in Germany, helped start Crispr Therapeuti­cs.

The prestigiou­s award comes with a gold medal and prize money of more than $1.1 million, courtesy of a bequest left more than a century ago by the prize’s creator, Swedish inventor Alfred Nobel. The amount was increased recently to adjust for inflation.
